Query StackMap — the curated map of the open-source AI stack — from any MCP client. 344 repos across 21 topics, 817 connections, every one typed (complements / alternative / built_with) and human-reviewed, with the why written down — including when NOT to use a tool.
No auth. No state. No telemetry. Reads the site's static JSON API; the catalog is date-versioned (v2026.07.24 style) so you always know how fresh the map is.

Cursor — .cursor/mcp.json:
Codex CLI — ~/.codex/config.toml:
| Tool | What it answers |
|---|---|
search_catalog | "What's on the map for local voice transcription?" |
get_repo | "Tell me about langgraph — including when NOT to use it." |
get_alternatives | "What replaces crewai, and when do I pick which?" |
continue_stack | "I use langgraph + chroma — what pairs well next?" |
build_stack | "Build me a starter stack for a local-first RAG pipeline over PDFs." |
Every answer carries the curator's written why — the sentence a colleague would tell you over your shoulder, not a link dump.
Nothing on the map auto-publishes: an LLM proposes, a human approves, sharpens, or refuses — and both the refusal ledger and the dismissal ledger are public. Suggest a repo at /suggest; dispute any edge from its repo page.
