Local index & search for your AI coding-agent threads — across 11 tools (Claude Code, Codex, Cursor, Gemini CLI, Qwen Code, Goose, OpenCode, Continue, Cline, Roo Code, Kilo Code) — plus a provider-agnostic chat, an MCP server, a CLI, and a VS Code / Cursor extension. Everything stays on your machine.
Named for Callimachus, who built the first catalogue of the Library of Alexandria.
MCP server for Callimachus: local index and search of your AI coding-agent threads

That memory is prepended when you "Open in CLI", and you can inject it into any agent automatically: Update AGENTS.md (or cal agents) writes a managed block into the repo's AGENTS.md / CLAUDE.md, and cal hook feeds it to a Claude Code SessionStart hook.[thread N] citations back to the sources it used. Needs an LLM engine (Knowledge/distillation enabled).git log's changed files inside the thread's time window (shared-file count = confidence).

First launch: the index is empty — open Settings (or hit Reindex) to index your sources, then Build semantic index to enable semantic search. Reindex runs as a background job with a per-source progress bar, separate from Build semantic index — the two are mutually exclusive (one pauses while the other holds the write lock).
cd apps/desktop/src-tauri
cargo test # fast unit tests
cargo test -- --ignored --nocapture # real-data + model + keychain smoke tests
The --ignored tests touch live data on this machine: each source has a real_<source>_index smoke test that indexes your real history read-only (~/.claude, ~/.codex, Cursor, ~/.gemini, ~/.qwen, Goose, OpenCode, Continue, Cline/Roo/Kilo), plus the embedding-model download (first run, needs network) and a Keychain round-trip.
Beyond the desktop window, the same local index is reachable from your agents, terminal, and editor — all reading one index.db.
MCP server — let any agent search its own past work mid-session. The quickest way is npx (it downloads the prebuilt binary on first run); it's also listed on the official MCP registry as io.github.betabots-llc/callimachus:
claude mcp add callimachus -- npx -y callimachus-mcp # or any MCP client
Already running the desktop app? callimachus-mcp is on your PATH, so claude mcp add callimachus -- callimachus-mcp works without npm. Building from a checkout instead? cargo install --path apps/desktop/src-tauri --bin callimachus-mcp.
Tools (21) — now read and write. Reads (17): search_threads, search_current_project (auto-scoped to the repo it runs in), recent_threads, get_thread, list_tags, list_open_todos, get_thread_knowledge, recall_decisions, recall_gotchas, find_prior_work (the "have I done this before?" guard — prior sessions similar to a task), project_memory (a project's aggregated decisions / gotchas / open TODOs), ask_history (a cited RAG answer over your history), threads_for_file (which sessions touched a path), check_decision (surface settled decisions before re-litigating a proposal), linked_commits (the commits a thread likely produced), list_snapshots (a project's session snapshots), and load_snapshot (restore a saved checkpoint). Writes (4, into Callimachus's own memory, never your code): complete_todo (close an open TODO), record_decision (optionally with a rationale), record_gotcha (persist a fact into a project's memory), and snapshot_session (checkpoint a thread for handoff). The bundled /recall skill (.claude/skills/recall) tells agents when to reach for them.
CLI — cal, pipe-friendly. Ships with the desktop app (on your PATH); or build from a checkout with cargo install --path apps/desktop/src-tauri --bin cal.
cal search "vector index migration" -y # -y = hybrid (semantic + keyword)
cal recent -n 10
cal cat 42 | pbcopy # packed transcript → clipboard
cal stats # index totals + per-source breakdown
cal export 42 --vault ~/Obsidian # write a thread as an Obsidian note
cal ask "how did we set up releases?" # cited RAG answer over your history
cal files embed/mod.rs # threads that touched a file path
cal memory # this repo's distilled memory (decisions/gotchas/TODOs)
cal done 17 # mark an open TODO done (id from `cal todos`)
cal remember decision "use sqlite-vec for KNN" --because "no cloud, KNN in SQL" # record a fact (+ rationale) into the repo's memory
cal check "switch to pgvector" # surface settled decisions before re-litigating one
cal commits # infer the thread→commit timeline for this repo (--json; or pass a path)
cal issues # recurring errors you keep hitting across sessions (last 180 days)
cal cost # estimated $ spend by model + your priciest threads
cal audit-pr . --changed-files a,b --shas s1,s2 # one JSON bundle for an external PR auditor
cal snapshot 42 -l "pre-refactor" # checkpoint a thread for handoff (transcript + project memory)
cal snapshots # list saved session snapshots (optionally for a project)
cal resume 7 -a claude # resume a snapshot in an agent CLI
cal agents # write the repo's memory into AGENTS.md (any agent reads it)
cal hook # print the repo's memory (use as a Claude Code SessionStart hook)
star, tag, tags, todos, knowledge, distill, decisions, gotchas, and related also exist — run cal help for the full list.
VS Code / Cursor — the extension adds a "Callimachus History" sidebar, a status-bar search button, and commands to search / insert / copy threads (it shells out to cal). Install from the VS Code Marketplace or Open VSX (the registry Cursor and VSCodium use), or grab the .vsix from Releases. See apps/vscode/README.md.
Issues and PRs welcome. CONTRIBUTING.md covers local setup, conventions, and the release flow. Adding support for another agent is a small, documented contract — usually one indexer module + a migration + a few wiring points.
Callimachus is local-first by design: your conversation index never leaves your machine, API keys live in the OS keychain (never on disk), and the only outbound traffic is to the LLM provider you explicitly choose. To report a vulnerability, see SECURITY.md.
