Openmetadata

A comprehensive MCP interface to OpenMetadata that goes well beyond the embedded 1.12+ server with 172 tools covering full CRUD across every entity type, including Data Contracts, Metrics, Search Indexes, and API Collections. You get aggregation tools like lineage-impact that walk the dependency graph and return blast radius with owner lists in one call, semantic search over the vector index, and token-efficient projections that strip 80% of response bloat. Ships with four workflow prompts for impact analysis and quality investigation, seven MCP resources for direct entity access, and category toggles to shrink the tool schema from 24k to 4.6k tokens. Use this when you need bulk operations, automation against older OpenMetadata clusters, or entity coverage the embedded MCP doesn't handle yet. Requires a JWT bot token and stdio or HTTP transport.
