description: 'Kimetsu (kimetsu.dev) is Rodrigo Córdoba''s open-source infrastructure for coding agents. Kimetsu itself
  is a local, model-free memory sidecar — one Rust binary and one SQLite brain per project — that Claude Code, Codex,
  Cursor, Pi and OpenClaw load as a local-stdio MCP server (~28 kimetsu_* tools), with a CLI, npm/cargo/PyPI packages,
  a self-hostable Kimetsu Remote HTTP MCP server and published benchmark numbers. The domain also operates agents.kimetsu.dev,
  a credential-free, read-only Agent Gateway with a published OpenAPI 3.1.0 (15 operations), an A2A Agent Card served
  at the RFC 8615 path (0.3 by default, 1.0 negotiated with the A2A-Version header) and a live JSON-RPC guide for
  Sidequest Commons — the maintainer''s daily public project-selection loop run through GitHub issues and reactions
  — plus llms.txt on two hosts, a /.well-known/kimetsu-agents.json discovery pointer and JSON Schemas for its discovery
  documents. Everything is MIT OR Apache-2.0. Seeded from the A2A Registry listing dev.kimetsu.sidequest_commons_guide
  under the harvest name "Sidequest Commons".'

  description: >-
    A2A agent (JSON-RPC; 0.3 message/send by default, 1.0 SendMessage with A2A-Version 1.0) that returns
    deterministic, credential-free guidance on discovering Sidequest Commons and on proposing, voting
    and contributing through GitHub. Two skills: discover_sidequests, explain_participation. No streaming,
    push notifications or tasks; performs no writes and rejects credentials. Listed in the A2A Registry
    as dev.kimetsu.sidequest_commons_guide.

  name: Kimetsu MCP Server (local stdio)
  description: >-
    The memory product's agent surface: `kimetsu mcp serve` exposes ~28 kimetsu_* tools (context retrieval,
    lesson recording, memory CRUD and curation, citations, conflict resolution, embedding-model management,
    repo ingest, skill bridge) over stdio to Claude Code, Codex, Cursor, Pi, OpenClaw and Gemini CLI,
    backed by a per-project SQLite brain with no cloud and no telemetry. No provider-hosted endpoint;
    Kimetsu Remote (beta) lets an operator self-host the same surface over HTTP MCP with bearer tokens.
    Distributed as npm kimetsu-ai, crates.io kimetsu-cli and GitHub Release archives (v2.8.0, 2026-09-09).
