FMagenticL MCP

FMagenticL is a deterministic, zero-cost Model Context Protocol registry that provides shared remediation for runtime exceptions across autonomous coding agents. It allows agents to query verified, SHA-256-signed patches and structured engineering workarounds in sub-100ms, eliminating debugging token burn by leveraging a global 'immune system' of solved bugs.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

fmagenticl_resolve

Advertised by the server during the last successful anonymous check.

Deterministic sub-100ms lookup of a signed patch or verified workaround for an agent execution error. Accepts raw error traceback / exception strings (raw_error), package/tool names (target), or pre-computed SHA-256 fingerprints (fingerprint). Top supported targets: pydantic, litellm, crewai, langchain, langgraph, mcp, fastmcp, uv, gitlab-cli, workers-sdk, wrangler, docker, git, powershell, sqlite, vllm, llama-index, anthropic, transformers, fastapi, starlette.

fmagenticl_auto_heal

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http fmagenticl-mcp https://fmagenticl-registry.pages.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add fmagenticl-mcp --url https://fmagenticl-registry.pages.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable fmagenticl-mcp in your MCP settings.

Cursor configuration

  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http fmagenticl-mcp https://fmagenticl-registry.pages.dev/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "fmagenticl-mcp": {
