Overview

AI-generated overview

Remote MCP server offering pay-per-call USDC services: bi-temporal memory storage and search, plus summarization, fact-checking, code review and embeddings.

What you can do
  • Discover the paid service catalog and read how the memory service works before buying
  • Provision an isolated bi-temporal memory namespace, store memories, and run semantic search over current beliefs
  • Retrieve a budget-packed context block for a completion, or replay what the store believed at a past time
  • Summarize documents, verify factual claims, review code snippets, and produce research briefs
  • Generate text embeddings in batches and create tamper-evident notarization records
  • Probe a URL's trust signals and aggregate bazaar statistics
When to use it
Use it when an assistant needs persistent, auditable memory with time-travel queries, or occasional paid one-off tasks such as summarization, fact verification, code review or embeddings, and you are willing to pay per call in USDC.
Requirements
A remote streamable HTTP endpoint; no local install. A wallet able to settle x402 payments in USDC on Base for paid tools. A tenant key issued by the provisioning tool, sent as the X-TENANT-KEY header for memory operations. Free tools need no payment or auth.
Before you install
Most tools cost USDC per call, and provisioning carries a monthly floor, so spending is real money. Payment is the identity for provisioning and the tenant key is shown only once, so losing it may mean paying again. Memory writes are append-only and supersede prior beliefs rather than deleting them. Research briefs use model knowledge only and carry no citations. Content is sent to a third-party service.

Installation

In SourceWeft

  1. Open Mnemos — memory as a service 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/com.virohanalife%2Fmnemos/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

Tools

agora_catalog

FREE. Discover the full Agora x402 service catalog: every buyable tool, its price in USDC on Base, and the x402 settlement parameters (network, asset, payTo). Call this first to see what you can buy and how to pay.

Takes no parameters.

summarize_demo

FREE. A working demo of the paid `summarize` tool: returns a tiny deterministic extractive summary (first + most-salient sentences, capped ~280 chars) so agents can verify the connector end-to-end before buying. No payment, no auth required.

Parameterstextrequired

summarize

PAID (0.03 USDC). Full-quality document summarization. Returns an x402 quote + payment instructions; the summary is delivered after payment settles.

Parameterstextrequiredmax_words

fact_verify

PAID (0.25 USDC). Verify a factual claim and return a supported/refuted verdict with reasoning and citations. Returns an x402 quote + payment instructions.

Parametersclaimrequiredsources

code_review

PAID (0.05 USDC). Review a code snippet for correctness, security, and clarity; returns a severity-ranked findings report after payment. Returns an x402 quote.

Parameterscoderequiredlanguage

research_brief

PAID (0.10 USDC). Structured synthesis brief on a topic, from local model knowledge only. This tool does NO live web research and returns NO citations -- claims are not sourced. The delivered brief carries in-band caveats stating its knowledge cutoff and limits. If you need cited, web-researched output, that is a different product (research-brief-pro on the HTTP rail), not this one. Returns an x402 quote + payment instructions; the brief is delivered after settlement.

Parametersdepthtopicrequired

notarize

PAID (0.10 USDC). Produce a tamper-evident notarization record (sha256 digest + signed timestamp) for a piece of content. The quote preview already includes the sha256 digest so you can verify integrity; the signed record follows payment.

Parameterscontentrequired

trust_check

PAID (0.05 USDC). Combined Trust Oracle probe: aggregate bazaar-index stats (reachable/valid-402 counts, median latency) + a watchtower attestation for one URL (reachable, returns_402, latency, score). Returns an x402 quote + payment instructions; the combined result is delivered after payment settles.

Parametersurlrequired

embed_batch

PAID (0.005 USDC). Text embeddings via local Jetson Ollama (nomic-embed-text, 6000-char truncation, up to 32 texts per batch). Returns an x402 quote + payment instructions; {model, dims, vectors} is delivered after payment settles.

Parameterstextsrequired

mnemos_saas_info

FREE. Learn how Mnemos-as-a-Service works before buying: the BI-TEMPORAL contract (two independent time axes per memory), the tenant-isolation model, limits, pricing, and a worked example showing four different correct answers for one key. No payment, no tenant data. Call this first.

Takes no parameters.

mnemos_provision

PAID (0.50 USDC, monthly floor). Mint your own fully isolated bi-temporal memory namespace. Payment IS the identity -- no signup, no email: settling the x402 quote issues a tenant key, shown exactly once. Returns an x402 quote.

Parameterslabel

mnemos_store

PAID (0.01 USDC). Store a memory in your isolated bi-temporal namespace. Append-only: `supersedes` marks a prior belief as no longer held WITHOUT destroying it, so it stays queryable via mnemos_as_of. `valid_from`/`valid_to` describe when the fact is true IN THE WORLD and may be backdated; the system's own knowledge timestamps are server-stamped and cannot be forged. Returns an x402 quote; requires header X-TENANT-KEY once settled.

Parameterskeyrequiredvaluerequiredvalid_tosupersedesvalid_from

mnemos_get_context

PAID (0.005 USDC). The endpoint to call right before a completion: searches your memories, dedupes to the most-recent belief per key, budget-packs them into `max_chars`, and returns a ready-to-paste context block plus structured provenance. Content flagged as prompt-injection is excluded from the block. Optionally assembled AS OF a past time. Returns an x402 quote.

Parameterskas_ofqueryrequiredmax_chars

mnemos_as_of

PAID (0.005 USDC). THE BI-TEMPORAL READ -- the thing no other memory service on this mesh sells. Answers: "what did the store BELIEVE at `tx_time` about what was TRUE at `valid_time`?" Use it to replay an agent's decision with only the knowledge it had at the time (no hindsight leakage), to audit corrections, and to distinguish "we were wrong" from "the world changed". Returns an x402 quote.
