RAGMap (RAG MCP Registry Finder)

RAGMap is a lightweight MCP Registry-compatible subregistry + MCP server focused on RAG-related MCP servers.

It:

• Ingests the official MCP Registry, enriches records for RAG use-cases, and serves a subregistry API.
• Exposes an MCP server (remote Streamable HTTP + local stdio) so agents can search/filter RAG MCP servers.

MapRag (RAGMap)

MapRag is a discovery + routing layer for retrieval. It helps agents and humans answer: which retrieval MCP server should I use for this task, given my constraints?

RAGMap does not do retrieval itself. It indexes and enriches retrieval-capable servers, then routes you to the right tool/server.

What you get after install (plain English)

• You get discovery/routing tools (rag_find_servers, rag_get_server, rag_list_categories, rag_explain_score).
• RAGMap helps you find the best retrieval server for your task and constraints.
• Your agent then connects to that chosen server to do the actual retrieval.

RAGMap does not:

• Ingest your private documents automatically.
• Host your personal vector database.
• Replace your end-to-end RAG pipeline.

If you need retrieval over your own data, use a retrieval server from RAGMap results (or your own server) that supports your ingest/index flow.

Freshness and ingest

• Hosted RAGMap updates its index on a schedule. Newly published/changed servers may appear with some delay.
• Most users do not run ingest themselves when using the hosted service.
• If you need tighter freshness control or private indexing behavior, self-host and run your own ingest schedule (docs/DEPLOYMENT.md).

Features: Registry-compatible API; semantic + keyword search (when OPENAI_API_KEY is set, e.g. from env or your deployment’s secret manager); categories and ragScore; filter by hasRemote, reachable (HEAD-checked), citations, localOnly, transport, minScore, categories. Human browse UI at ragmap-api.web.app/browse — search, filter, copy Cursor/Claude config. MCP tools: rag_find_servers, rag_get_server, rag_list_categories, rag_explain_score.

Local dev

cp .env.example .env
corepack enable
pnpm -r install
pnpm -r dev

Optional: set OPENAI_API_KEY in .env (see .env.example) to enable semantic search locally; GET /health will show "embeddings": true.

API: http://localhost:3000 MCP remote: http://localhost:4000/mcp

Ingest

curl -X POST http://localhost:3000/internal/ingest/run \
  -H "Content-Type: application/json" \
  -H "X-Ingest-Token: $INGEST_TOKEN" \
  -d '{"mode":"full"}'

MCP usage

Remote (Streamable HTTP):

claude mcp add --transport http ragmap https:///mcp

Local (stdio, npm):

npx -y @khalidsaidi/ragmap-mcp@latest

Local (stdio):

pnpm -C packages/mcp-local dev

Key endpoints

• GET /embed — embeddable “Search RAG MCP servers” widget (iframe; query params: q, limit)
• GET /health (includes embeddings: true|false when semantic search is on/off)
• GET /readyz
• GET /v0.1/servers
• GET /v0.1/servers/:serverName/versions
• GET /v0.1/servers/:serverName/versions/:version (supports latest)
• GET /rag/search
• GET /rag/categories
• GET /api/stats (public usage aggregates; no PII)
• GET /api/usage-graph (HTML chart of usage)
• POST /internal/ingest/run (protected)

For hosted ragmap-api.web.app, /internal/* routes are not exposed publicly.

GET /rag/search query params:

• q (string)
• categories (comma-separated)
• minScore (0-100)
• transport (stdio or streamable-http)
• registryType (string)
• hasRemote (true or false — only servers with a remote endpoint)
• reachable (true — only servers whose streamable-http URL passed a HEAD check)
• citations (true — only servers that mention citations/grounding in metadata)
• localOnly (true — only stdio, no remote)
