Bug Fixes

Fix: datahub_get_entity, datahub_get_lineage, datahub_get_data_product broken through Claude.ai

Bumps mcp-datahub to v1.0.3, which fixes three tools that were returning "Anthropic Proxy: Invalid content from server" when called through Claude.ai. Direct MCP clients were unaffected. The root cause was structured output responses not matching the declared OutputSchema on each tool.

  • datahub_get_entity — entity fields are now returned flat at the top level; query_table, query_examples, and query_availability appear at the same level rather than nested under a wrapper key
  • datahub_get_lineage — lineage fields are now returned flat at the top level; schema field names corrected (start/nodes/edges/depth) to match the actual response structure
  • datahub_get_data_product — schema now declares the properties field, which caused proxy rejection when populated

See mcp-datahub v1.0.3 for full details.
