mif-mcp

MCP server for the MIF (Modeled Information Format) ecosystem.

Exposes six tools over stdio, mirroring mif-cli:

• validate_mif_document — validate a MIF document (markdown with frontmatter, or JSON-LD) against the canonical schema, with no side effects (no embedding model load, no vector store write).
• resolve_ontology_reference — resolve an ontology's three-tier extends chain.
• ingest_mif_document — lint, validate, prove a lossless round trip, compute an embedding, and store the embedding vector for one MIF document (markdown with frontmatter, or JSON-LD). db_path defaults to .mif/vectors.db, created (with its parent directory) if absent.
• search_documents — free-text semantic search over previously ingested documents. limit defaults to 10.
• find_similar_documents — find previously ingested documents similar to an already-ingested one, identified by its id. limit defaults to 10 and excludes the anchor document itself.
• corpus_stats — summary statistics (count, embedding dimensionality) over the vector store.

Error output format

An MCP client is inherently a machine consumer — there is no terminal to detect — so every tool failure renders as a compact RFC 9457 application/problem+json envelope rather than plain text, using the same mif_problem/ToProblem pattern as mif-cli's --format json.
