Run local Froglet verifiable compute, signed receipts, settlement, and service publication.
Overview
Froglet's MCP bridge lets an assistant discover, invoke and publish verifiable compute services and inspect signed receipts on a local Froglet node.
- What you can do
- Discover and invoke published services, and run open-ended compute against a chosen provider
- Publish services and local artifacts through a two-step marketplace publication flow, with status, logs, pause, resume, rollback and confirmed unpublish
- Check node status, poll tasks, and view settlement and marketplace wrappers
- Plan an install without writing anything, then generate an approved install command, and plan a use case after install
- Prepare fixed HTTPS JSON services, issue expiring invitations and control admission limits (native bridge)
- When to use it
- Useful when you want an agent to publish a data catalog or small Wasm function as a service another agent can call, or to run bounded compute and get signed, hash-linked evidence of what was authorised. Also relevant for self-hosted operators who need publication lifecycle control from an agent host.
- Requirements
- Runs as a local process over stdio; the npm package defaults to a local profile pointing at the local node's provider and runtime URLs. A running Froglet node and its local token files are needed for most actions, referenced by environment variables such as FROGLET_PROVIDER_AUTH_TOKEN_PATH and FROGLET_RUNTIME_AUTH_TOKEN_PATH. Supported targets are Apple Silicon macOS and Linux x86_64/arm64, and the host must stay online.
Installation
In SourceWeft
- Open Froglet in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.

Froglet
The rail-neutral evidence layer for agent transactions.
[CI] [Release] [License: Apache-2.0] [Rust] [Edition] [Docker]
Whatever rail moves the money, Froglet produces a signed, hash-linked record of what was authorised, under which limits, and what the executing party attested to — verifiable offline by anyone, with no node and no account.

Overview
Launch preparation, 2 October 2026: the current scope is free selected-data sharing and bounded Wasm through native MCP, with optional configured A2A. Use the production handoff and explicit remaining gates. Local software checks, local packages and the public documentation website do not qualify a new production compute deployment or an immutable release.
Development checkpoint, 1 October 2026: work has resumed on the free native MCP workflow, optional configured A2A transport, and selected-data sharing with bounded Wasm computation. The final candidate's actual Codex CLI workflow and extracted demo bundle are qualified on the current Apple Silicon Mac. The same production inputs also passed 625 library and nine native MCP tests, plus the terminology workflow, in an isolated Linux arm64 development container. Thirteen library tests were ignored; Python OS isolation and a Linux agent host remain unqualified. Claude Code host qualification is blocked on sign-in. Selected-data/profile examples and bounded local capacity have recorded checks; clean machines, public compute HTTPS/capacity, and first-user value remain separate gates. See current work and the qualification evidence.
The public documentation website was restored on 1 October; seven checked routes returned HTTP 200 and matched the local build bytes. See the deployment record and remaining gates. The last observed hosted compute trial was unavailable; this pass has not requalified that deployment. Production and available hosted compute qualification remain open. The immutable v0.4.7-beta.1 prerelease is now published; its downloaded Apple Silicon binary passed a separate deterministic localhost replay. Distribution and exact released-Mac evidence also record a separate native-MCP Mac-to-Fly proof: six bounded free cases, restart persistence and offline task recovery on one isolated test host, now removed. That proof does not qualify production, load, a fresh agent host, a clean operating system or paid operation. The September pause and rollback record is preserved. File downloads remain experimental; Node/UI/relay qualification is open. General CPU jobs, GPU rental, and new payment work are outside the resumed scope.
The optional research profile makes namespace, version, field types, units, provenance and mapping assumptions explicit. The final local example retrieves a pinned public GO catalog in 100- and 40-row pages with verified receipts; this establishes data exchange and declared metadata compatibility, not scientific correctness or independent user demand.
On one shared machine, eight concurrent tiny workflows using independent requester identities completed without errors in the measured sweep. At 16 and 32, six selected-data jobs hit the four-process limit and returned independently verified failure chains. Shared requester identities still face about one identical requester/workload/terms Quote per second; collisions now fail before Deal admission and leave no pending requester submissions. These measurements do not establish production capacity, performance superiority or developer-time savings. See the exact local qualification.
The current product candidate starts with “Make this catalog usable by another agent.” Codex or Claude Code can prepare selected JSON, typed CSV, or SQLite data, or a small Wasm function; run a local example; ask for exact publication approval; and return a provider/service share link. Native setup preserves existing agent settings. Recipients use the same native integration without npm.
See the publishing workflow and the qualification gates. This is a public prerelease: clean-machine agent tests, the real public relay journey through this profile, and first-time-user acceptance remain qualification gates. The first-user trial kit separates setup usability from evidence of a useful job. Supported targets are Apple Silicon macOS and Linux x86_64/arm64. The host must stay online.
The local captured-program replay now has complete evidence: Alice's retained
81,222-byte Wasm program matched four independently frozen answers, and all
seven admitted signed chains were verified offline. The seven include an owner
control, selected-data retrieval, four program executions and a separate looping
program's budget failure. Exact completed data and compute retries recovered
cached results after Bob stopped and Alice restarted. In that historical replay,
get_task returned HTTP 502 with Bob stopped. The 3 October correction now
revalidates saved terminal task evidence locally; unsigned or unresolved tasks
still require Bob for refresh. Current-source local regressions pass; a fresh
optimized native candidate also passed independent verification of all seven
chains and all six saved Alice terminal task reads after Bob stopped and Alice
restarted. Package/release gates and website publication remain separate checks.
This is deterministic replay of a program created in an earlier actual Codex session. That earlier fresh-session qualification remains failed because its complete chains were not captured and persistent Codex configuration changed. The replay starts no LLM, compiler or agent settings operation. See the reusable runbook and local finalization evidence.
Froglet gives one signed economic primitive for three product shapes:
The primary bot-facing integration surfaces are intentionally simple:
- One OpenClaw/NemoClaw plugin id:
froglet(atintegrations/openclaw/froglet/) - One MCP server under
integrations/mcp/froglet/, published asfroglet-mcpfornpx froglet-mcp, plus a dependency-minimal native bridge infroglet-node mcp - Both surfaces register a single agent-facing tool named
frogletto the host (Claude Code, Codex, Cursor, Windsurf, etc.). The headline action is two-stepmarketplace_publish: the first call is a non-mutating plan, and the second must carry the exact approvedconsent_hash. Both native and JavaScript adapters delegate to the same Rust publication module and provider-control contract. - The
froglet-nodebinary is both the daemon (running as a provider) and the author CLI (froglet-node init/build/publish/whoami,prepare-service,invoke,doctor, andcheck-updates).status --open --jsonreturns a short-lived read-only local status URL.
Bots should be able to create small scriptable services directly, validate them locally, and publish them without starting from OCI images. OCI containers remain a supported packaging and deployment path.
Product Model
- Any Froglet node can publish resources and invoke remote resources
- Published resources are execution bindings backed by bot-authored projects, explicit source, or prebuilt artifacts
- Easy bot authoring and local checking of scriptable services is a core product requirement
- Identity is first-class in signed artifacts
- Clearnet HTTPS, outbound relay HTTPS, and Tor v3 onion transport are supported registration paths for self-hosted providers. Bootstrap plans the official relay URL and suffix by default but keeps them dormant; publication fails closed until an exact durable grant makes the endpoint ready. Planned configuration is not a claim that its public operator service is deployed.
[!NOTE] Marketplace, ranking, incentive, and broker policy live above the protocol. Payment rails are adapter-level surfaces for local or self-hosted operators, not normal buyer onboarding. Lightning, Stripe, and x402 are the launch adapters in this repo. Lightning and x402 have standardized kernel settlement methods with conformance vectors; Stripe's
stripe_mpp.v1receipt shape is standardized but attested rather than cryptographic. Only Lightning escrow uses the signed invoice-bundle flow. x402's wire format is settled (x402.eip3009.v1,conformance/x402_v1.json) but its rail is not: no publish-path exposure and no live transcript on any network. The first-party hostedtry.froglet.devtrial was retired on 8 October 2026; the free public beta at https://froglet.dev/services/ replaces it. Hosted paid rails must not be claimed live until Lightning and Stripe have public payment transcripts, and users should not be asked to manage LND channels or payment secrets just to try Froglet.
Discovery & Compute model
- Named services and data services are discovered through discovery
- Open-ended compute uses the provider's direct compute offer via
run_compute, targeted withprovider_idorprovider_url - Publication and bootstrap adapters may include Nostr-style publication without making any single relay or network the kernel source of truth
Components
Product-wise, Froglet is one node that can both provide and consume. The reference implementation exposes these binaries:
[!TIP] Marketplace integration is part of the public Froglet surface. Runtimes can point at the default public marketplace with
FROGLET_MARKETPLACE_URL; providers can self-register there after exposing a public HTTPS URL, identity-assigned relay URL, Tor v3 onion URL, or claimed*.providers.froglet.devhostname. See docs/MARKETPLACE.md.
Prerequisites
Binary install (quickest): curl, tar, sha256sum (Linux) or shasum (macOS). Supported: Linux x86_64/arm64, macOS arm64.
Build from source: Rust 1.91+, Python 3.12+ (for tests), Node 18+ with npm (for Claude Code/Codex MCP setup and integration tests).
Docker (optional fallback/contributor stack): Docker with Compose v2.
Quick Start
Canonical onboarding lives in
docs-site/src/content/docs/docs.mdx
(the learn/ index remains as a legacy route).
Use the repo README for the product and codebase overview, the docs-site
manual for the public launch path, and docs/ for specs, operator notes, and
integration reference.
The public launch story still has exactly two entry points:
1. Try the public beta
- Open https://froglet.dev/services/ in a browser: no installation, signup or invitation. It runs your bounded Wasm program or a synthetic catalog query on a real remote node and returns signed evidence the browser verifies.
- Scope and limits: docs-site/src/content/docs/learn/cloud-trial.mdx
- The older hosted trial at
try.froglet.dev(and itsai.froglet.devorigin) was retired on 8 October 2026; see docs/HOSTED_TRIAL.md. - The public beta does not prove paid rails, persistent identity, service publication, marketplace depth, or general runtime access.
2. Run Locally
- Start with docs-site/src/content/docs/learn/quickstart.mdx
- Then use docs-site/src/content/docs/learn/agents.mdx and docs-site/src/content/docs/learn/payment-rails.mdx
- Self-host and operator follow-ons live in docs/DOCKER.md, docs/GCP_SINGLE_VM.md, and docs/MARKETPLACE.md
Minimal full local stack from zero:
plan is the safe default and writes nothing outside its temporary workspace.
It resolves the immutable release, verified manifest and target-platform binary
asset digests, exact bootstrap/install/configuration script digests, persistent
paths, and service-manager impact into one canonical approval hash. execute
recomputes that contract and stops before any persistent write if the release,
script bytes, profile, paths, or supplied hash changed.
After approval, the agent bootstrap verifies a Release Bundle, installs the checksum-verified
froglet-node, starts the native dual-role service through launchd/systemd,
writes native MCP config, and returns only after health plus a non-seeding MCP
status proof and a transient read-only data proof that is confirmed-unpublished.
The proof first requires an empty active-offer feed and no lifecycle for its
exact service ID, records a private cleanup intent before publishing, and
removes both its offer and authoring directory only after an empty-feed check.
A failed proof attempts exact unpublish while the service is still live and
preserves a recovery marker if cleanup cannot be proved.
A digest-pinned dual-role GHCR image is the fallback
when native service management is unavailable.
The approval plan includes the official relay endpoint and DNS suffix by
default. This is dormant configuration: it derives an exact planned HTTPS URL
but opens no WSS connection and exposes no service before an exact durable
publication grant. Set both FROGLET_RELAY_URL='' and
FROGLET_RELAY_PUBLIC_SUFFIX='' before plan to opt out. The first-party
DNS/TLS endpoint is not yet live-proven, so relay publication remains an
explicit external gate rather than an install success claim. See
docs/RELAY.md. The implementation/evidence matrix in
docs/AGENT_FIRST_PUBLICATION_PLAN.md
tracks which clean-host and external gates remain open.
From a trusted checkout, run the disposable-host proof with
bash scripts/fresh_host_quickstart_smoke.sh.
The lower-level scripts/install.sh is an internal release-bundle installer;
agents should use the approval-gated bootstrap above.
Source-checkout Compose and generated host-side agent configs depend on
FROGLET_HOST_READABLE_CONTROL_TOKEN=true; the default user path is the
no-clone /agent bootstrap. The quickstart page carries the step-by-step
MCP-first explanation, payment-rail decisions, Tor registration, managed
subdomains, and contributor/source-mode fallbacks.
Running binaries directly (without Compose)
The normal model is one node running both provider and runtime roles
(FROGLET_NODE_ROLE=dual), so it can publish local resources and invoke
remote ones.
Set FROGLET_MARKETPLACE_URL on runtime nodes to search through an external
marketplace. Providers can self-register with the default public marketplace
after they advertise a matching public HTTPS origin, assigned relay HTTPS URL,
Tor v3 onion URL, or claimed *.providers.froglet.dev hostname.
Bot Surfaces
OpenClaw, NemoClaw, and MCP-compatible hosts are the primary bot-facing surfaces today. Distribution status and marketplace/plugin ordering live in PLUGIN_DISTRIBUTION.md.
OpenClaw & NemoClaw
Use the shared plugin package in
integrations/openclaw/froglet.
Current OpenClaw plugin install/inspect and gateway invocation require
Node.js 22.14.0 or newer. Gateway-mediated local actions should launch with
FROGLET_PROVIDER_AUTH_TOKEN_PATH and FROGLET_RUNTIME_AUTH_TOKEN_PATH
pointing at the local data/runtime/ token files.
Configuration keys
The generated local OpenClaw config uses the split provider/runtime keys above.
Legacy baseUrl and authTokenPath remain supported for single-surface
configs such as the checked-in NemoClaw examples.
The one froglet tool covers:
- Service discovery and invocation
- Agent-grade service publication via
marketplace_publish - Local artifact publication via
publish_artifact - Settlement visibility and current marketplace wrappers
- Status and task polling
- Exact install approval via non-mutating
plan_install, then approved command generation viaget_install_guide - Post-install workflow planning via
plan_use_case - Raw compute
Important behavior notes

MCP: native default and JavaScript compatibility
The no-clone native install configures the released binary directly:
This bridge needs no Node.js runtime. Its deliberately focused froglet tool
supports status, invoke_service, run_compute, get_task, two-step
marketplace_publish, and publication status/logs/pause/resume/rollback/
confirmed-unpublish. Durable cloud-adapter work is separately visible through
managed-operation status, confirmed reconciliation, and confirmed compensation.
local_proof is available only when an operator has
deliberately enabled the bundled demo catalog; clean installation does not.
Publication delegates to the same canonical project
loader, consent logic, and provider-control API as the CLI.
For bounded inline Wasm computation and optional A2A transport, use a binary built from this checkout or a release that includes these actions. The local MCP/A2A demo starts isolated Alice and Bob Nodes and exercises the real native MCP path. It uses free loopback computation and separate private A2A credentials; it does not configure a production wallet or publish a service externally. The supported profile and remaining release gates are in the interoperability specification.
The JavaScript MCP package is the broader compatibility and contributor surface for discovery, settlement, install planning, raw compute, and existing host integrations:
The npm package defaults to FROGLET_PROFILE=local, with provider/runtime URLs
pointing at http://127.0.0.1:8080 and http://127.0.0.1:8081. Agents should
call status first. If the local node or token files are missing, call
plan_install, show its immutable release tag, manifest/bootstrap SHA-256
values, persistent paths, process-manager impact, and exact command preview,
then wait for approval. Only after approval, pass the returned release_tag
and install_approval_hash unchanged to get_install_guide and run its
verified-temp-file command through the host shell. After local health is
verified, use plan_use_case before
implementing consumer, provider, evidence, payments, batch, or GPU workflows.
The native froglet-node mcp bridge also prepares fixed HTTPS JSON services,
issues expiring invitations into private files, and controls durable admission
limits. See bounded HTTP services and invitations.
Payments remain a separate operator decision. Public marketplace canaries
currently require anonymous access; private/invite services use direct provider
invocation.
GPU execution is currently unavailable: the reference OCI worker does not
attach or account for devices. GPU capabilities are not advertised and GPU
requests fail explicitly. Earlier Docker/GCP hardware proof does not qualify
this worker. Batch fan-out, GPU scheduling and general storage remain separate
work. The public no-install proof remains the HTTP flow at
https://froglet.dev/llms.txt; it is not an installed MCP action.
For a local node, use the local profile:
From a source checkout, the same server can be run directly:
The npm, source-checkout, and digest-pinned MCP-image modes expose the broader JavaScript surface over MCP stdio. The native mode exposes the smaller dependency-free publication/lifecycle surface above; it does not claim action parity with JavaScript.
For normal users, the /agent bootstrap writes the local MCP config without a
repo clone. From a source checkout, contributors can still generate the exact
config file instead of editing JSON or TOML by hand:
Portable Managed Hosting and OCI Isolation
froglet-service/v4 expresses managed hosting as a provider-neutral
target/profile. It does not contain AWS regions, Lightsail names, Fly apps,
ECR repositories, or cloud SDK types. The sibling
Managed Deployment operator (private froglet-services repository, not open source)
implements the corresponding portable desired-state lifecycle through the
current Lightsail compatibility adapter or generic SSH + OCI adapter and
returns the same normalized result shape. Publish-engine-to-operator wiring
and credentialed live canaries remain separate open gates.
V3 manifests remain readable. hosting.default = "fly" and hosting.fly.*
are deprecated compatibility inputs only; new authoring uses v4 managed, and
provider selection belongs in operator-owned adapter configuration. See
docs/PUBLICATION_CONTRACT.md.
Arbitrary OCI execution does not give the Froglet Node a Docker/Podman socket.
The node sends a digest-only, bounded, capability-reduced request to an
authenticated worker endpoint configured by FROGLET_OCI_WORKER_URL and
FROGLET_OCI_WORKER_TOKEN_PATH. The reference
OCI worker (private froglet-services repository, not open source)
owns rootless engine access and defaults to read-only, non-root, no-network
execution. With no worker configured, OCI execution fails closed.
Verification
Verifying artifact chains (what a counterparty does)
froglet-verify is a standalone offline verifier: no node, no network, no
account, and no clock unless you supply one. Point it at a chain and it checks
every envelope signature, every per-artifact semantic rule, and every hash link
between artifacts.
It accepts a single artifact, a JSON array, a /v1/feed page, or a conformance
fixture, from a file or stdin; --json emits a machine-readable report and
--now <unix> turns on expiry checks. Exit codes: 0 valid, 1 invalid,
2 usage error.
To check what a running node publishes, pipe its feed straight in. The feed is paged, so the verdict covers the page you fetched:
The Rust facade, browser WASM build, and in-repo Rust conformance runners share
the froglet-protocol implementation. python/froglet-verify
is independently implemented and checks the same public vectors. Multiple Rust
runners exercise distribution paths; they do not provide implementation diversity. See
conformance/README.md for what a conforming runner must
assert, and docs/SPEC.md for the normative rules.

Current Scope
In this repo now:
- Protocol and supporting specifications under
docs/andconformance/— stability guarantees in docs/VERSIONING.md; to build a second implementation in another language, start from the canonical test vectors inconformance/kernel_v1.json(guide: froglet.dev/spec/conformance) - Reference Froglet node implementation: a single
froglet-nodebinary serving split provider and runtime planes (published asfroglet-providerandfroglet-runtimecontainer images) - OpenClaw source-plugin integration and shared NemoClaw plugin code, with host-specific verification status documented separately
- Native dependency-minimal MCP bridge plus the broader JavaScript MCP server for external agent hosts and automations
- Python-backed helpers and tests for the public node and protocol surface
- Local project authoring, build, test, and publish flows for bot-authored services
- Direct artifact publication for prebuilt Wasm and OCI-backed profiles
- Reference execution profiles for Wasm, Python, container, and confidential execution paths
- Local/self-hosted reference settlement support for operator-controlled Lightning, Stripe, and x402
- Clearnet and outbound relay transports plus optional self-hosted Tor and Nostr-facing adapter support; live public relay readiness is an external deployment gate, not inferred from the client implementation
- Tests, validation scripts, and release docs for the public repo surface
- Public-facing self-host documentation and examples
Later or separately deployed:
- First-party hosted paid rail claims for Lightning and Stripe, pending public live transcripts; hosted x402 remains desirable but non-blocking
- Higher-layer marketplace ranking, reputation, and policy services
- Long-running batch orchestration, which remains out of scope for the current v1 runtime surface
- Credentialed live proof for the provider-neutral Lightsail and generic SSH +
OCI Managed Deployment adapters maintained in
froglet-services - Additional provisioning adapters for GCP, OVH, and similar providers when demand justifies them; no new provider enum belongs in the manifest
- Zip or archive packaging as a first-class execution submission format
- First-party hosted control-plane operations and runbooks
[!WARNING] Execution hardening is not uniform across all runtimes. Wasm is the strongest runnable in-process isolation path. Confidential/TEE artifact types remain protocol scaffolding only: this build rejects mock attestation/key-release policies and does not advertise
tee.*runtimes. Python requires Linux Landlock ABI v3 plus seccomp; OCI/container execution inherits the separately configured worker's isolation characteristics.
Documentation
First-party hosted deployment tooling and operator runbooks are maintained separately from the public protocol and self-host docs in this repo.
