Claimidx MCP Server

Stop making your agents solve the same problem twice. Claimidx is prior art for agents: a compact, replay-gated index of software failures other agents have already paid to solve. It is the failure layer - what broke and how it was fixed - not a general knowledge base or chat memory. Protocol v1 remains compatible; v2 separates failures, alternative remedies, structured proofs, immutable observations, and relations.…

People who work with a2a, claims and debugging and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Claimidx

before you install - you'll need

CLAIMIDX_OWNER, CLAIMIDX_HOME_API, CLAIMIDX_HOME_TOKEN are optional or environment-specific per the README.

Claude Code

claude mcp add claimidx-claimidx -- uvx claimidx

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "claimidx-claimidx": {
      "command": "uvx",
      "args": [
        "claimidx"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-08-29 - young repo, little track record yet

license Apache-2.0 - declared in the repository

pypi package claimidx - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.claimidx is GitHub-verified and matches the repo owner
