Verifiable cognition: any agent file to a deterministic content-addressed brain_id.

Overview

AI-generated overview

Remote MCP service that compiles an agent file into a deterministic, content-addressed brain_id and lets an assistant re-verify that identifier.

What you can do
  • Detect which supported agent-file format a piece of content is
  • Compile agent content into a deterministic, content-addressed brain with node and edge counts, an invariant firing report and provenance
  • Recompute a brain from submitted content and check a claimed brain_id or content_hash against it
  • Return the service's capabilities and input contract
When to use it
Useful when you need a reproducible fingerprint for an agent definition and want an assistant to check that a claimed brain_id or content_hash actually matches the submitted content, rather than trusting a label.
Requirements
A remote streamable HTTP endpoint; no packages, environment variables or headers are declared. The README notes a free tier of 10 calls per day per service on the hosted fleet, with verification always free.
Before you install
Content you submit is sent to a third-party hosted service, so avoid sending secrets or private agent files. The README states the hosted service layer, including payment, settlement, signing authority and customer data, is proprietary and separate from the open-source cores.

Installation

In SourceWeft

  1. Open Verdigraph in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.jdhart81%2Fverdigraph/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

Viridis Agent Fleet: open-source agents for the agent economy

Deterministic, auditable MCP agents: trust and settlement rails (identity, trust, escrow, metering, arbitration, notary, surety, provenance, covenant, offsets, compute-ledger) and priced-grade services (tax credits, GHG accounting, construction takeoff, measurement, compliance). Every core is pure Python with no LLM in the serving path, and every result is content-addressed so anyone can re-verify it.

Licensed Apache-2.0. Run any agent yourself, fork it, embed it.

Run an agent locally (free, forever)

bash
pip install -r requirements-dev.txtpython3 agent-escrow-agent/adapters/mcp_server.py          # stdio MCPpython3 run_fleet_tests.py                                 # every agent's invariant tests

Or use the hosted fleet

https://mcp.viridisconservation.com runs all agents as one managed MCP service:

Self-hosted (this repo)Hosted by Viridis
Agent logic & verification✅ identical✅ identical
Viridis-signed receipts & notary chain–✅
Shared trust/reputation network data–✅
Maintained rule packs (tax, GHG factors, regs)snapshot✅ kept current
Payments (x402, card), seats, SLA–✅

Free tier: 10 calls/day per service; the rails (identity, escrow, metering…) are free forever. Verification is always free.

For agents

Agents and LLM tools can start from llms.txt, a generated index of every agent, and AGENTS.md, the rules for using and changing the fleet.

Part of the Viridis open-source commons

Building agents for conservation or energy work? VergeCommon and EnergyAI MCP also expose MCP tools, and ViridisOS serves its decision functions to agents over MCP.

This project is one of a connected set of open tools from Viridis. Each stands on its own; together they run from field evidence to checked decisions.

Conservation commons

Verifiable science

  • Viridis Canon: machine-checked Lean 4 mathematics for ecological decisions, with a DOI for every result
  • ViridisOS: open reference runtime for DOI-backed decision modules and recomputable results
  • Viridis Research: the nightly public research record, each claim labeled by what a verifier actually checked
  • ProofLens: see what a Lean statement means before reading the proof

Agent tools

  • Viridis Agent Fleet (this repository): open-source MCP agents with deterministic, auditable cores
  • EnergyAI MCP: energy-planning estimates and incentive sources for AI agents

Boundary

This repo contains agent cores, MCP adapters, tests, standards and self-host tooling. The hosted service layer (gateway, payment and settlement, seats, signing authority, operations, telemetry and customer data) is proprietary and is not in this repo. Please don't open PRs that add it.

Tools

4

build_brain

Compile an agent file into a deterministic, content-addressed brain. content = the file as a string; format = verdigraph_genome | claude_project_export | openai_assistant | prompt_list | auto. Returns brain_id, content_hash, node/edge counts, the 9-invariant firing report, and provenance. Identical bytes always produce the identical brain_id (VB1). include_document=true returns the full graph.

Parametersformatcontentrequiredrequest_idinclude_document

verify_brain

Machine-check a cognition claim: recompute the brain from the submitted content and compare against the claimed brain_id and/or content_hash. valid=true iff every claimed identifier matches the deterministic recomputation (VB3).

Parametersformatcontentrequiredbrain_idcontent_hash

detect_format

Detect which supported agent-file format the content is (verdigraph_genome, claude_project_export, openai_assistant, prompt_list) before building.

Parameterscontentrequired

describe_agent

Return capabilities and input contract.

Takes no parameters.
