Minirag MCP Server

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: BASE_DIR (One document root; also the security boundary for file access. Defaults to the process working directory. Ignored when BASE_DIRS is set.), BASE_DIRS (JSON array of document roots, e.g. ["/docs/a", "/docs/b"]. Takes precedence over BASE_DIR. An invalid value is a hard configuration error.), DB_PATH (LanceDB index directory. Defaults to <first root>/.minirag/lancedb, so each corpus gets its own index.), CACHE_DIR (Embedding model cache. Defaults to the platform user cache dir, so the ~220 MB model is downloaded once and shared.), MODEL_NAME (fastembed model id. Changing it makes existing vectors incompatible with new queries; pair with a new DB_PATH or a full re-ingest.), MAX_FILE_SIZE (Per-file size limit in bytes, enforced before parsing.), CHUNK_TOKEN_BUDGET (Retrieval-unit size in the embedding model's own tokens. Range 16-128; the ceiling is the model's trained sequence length.), RAG_HYBRID_WEIGHT (Keyword weight in the weighted RRF fusion, range 0.0-1.0. 0 is vector-only; higher values raise the BM25 contribution.), RAG_GROUPING (Result grouping filter. 'similar' keeps only the closest group; 'related' also keeps the next one. Unset means no grouping filter.), RAG_MAX_DISTANCE (Drop results whose vector distance exceeds this value. Lower is stricter. Unset means no distance filter.), RAG_MAX_FILES (Keep chunks from at most this many best-scoring files. Unset means no per-file filter.), RAG_INSTRUCTIONS_APPEND (Extra paragraph appended to the instructions the server hands the client at connect time, for corpus-specific guidance.), ALLOW_PRIVATE_URLS (Let ingest_url fetch hosts resolving to loopback, link-local, private, reserved or unspecified addresses. Off by default.). The author declared them in the registry entry; get the values from the project itself.
