@ship-with-ai/stackmap-mcp

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.

Install

Claude Code

claude mcp add stackmap -- npx -y @ship-with-ai/stackmap-mcp

Cursor — .cursor/mcp.json:

{ "mcpServers": { "stackmap": { "command": "npx", "args": ["-y", "stackmap-mcp"] } } }

Codex CLI — ~/.codex/config.toml:

Tools

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.

How the data is made

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.
