Callimachus MCP Server

MCP server for Callimachus: local index and search of your AI coding-agent threads

The short version

Named for Callimachus, who built the first catalogue of the Library of Alexandria.

• Indexes — every conversation from 11 coding agents into one local SQLite store — Claude Code, Codex, Cursor, Gemini CLI, Qwen Code, Goose, OpenCode, Continue, Cline, Roo Code, and Kilo Code. Adding another source is a small, documented contract
• Searches — them with hybrid ranking: keyword (SQLite FTS5 / BM25) fused with on-device semantic similarity (sqlite-vec KNN, no cloud) via Reciprocal Rank Fusion. Filter by source, project, subagents, starred, and tags
• Finds code-aware — — type file:embed/mod.rs in the search bar (or cal files ) to find every thread that touched a path; backed by a file-mention index built at index time
• Curates the facts — — pin, edit, or delete distilled facts so your edits survive re-distilling, plus an LLM "Review conflicts" pass that flags decisions that contradict each other
• Asks your history (RAG) — — a synthesized, cited answer over your own threads, with [thread N] citations back to the sources it used. Needs an LLM engine (Knowledge/distillation enabled)
• Organizes into collections — — star threads and attach free-form tags, then filter the list by starred or by tag
