mcp-data-platform-v1.45.0

CRUD Write Tools for DataHub

Replaces the 7 individual DataHub write tools with 3 unified CRUD tools using a what discriminator pattern. Bumps txn2/mcp-datahub from v1.4.3 to v1.5.0.

Before (7 tools)

datahub_update_description, datahub_add_tag, datahub_remove_tag, datahub_add_glossary_term, datahub_remove_glossary_term, datahub_add_link, datahub_remove_link

After (3 tools)

Tool	Purpose
datahub_create	Create tags, glossary terms, links, structured properties, incidents
datahub_update	Update descriptions, structured property values, resolve incidents
datahub_delete	Remove tags, glossary terms, links, structured properties

Each tool accepts a what parameter that selects the operation type (e.g., datahub_create with what: "tag" replaces datahub_add_tag).

Read-Only Mode

A new read_only configuration option for the DataHub toolkit controls whether write tools are registered:

toolkits:
  datahub:
    instances:
      primary:
        read_only: true   # Only register read tools

When read_only: true, the three CRUD tools (datahub_create, datahub_update, datahub_delete) are not registered. Defaults to false.

Breaking Changes

Persona configurations referencing the old write tool names must be updated:

Old Pattern	New Pattern
datahub_add_*	datahub_create
datahub_update_description	datahub_update
datahub_remove_*	datahub_delete

Bug Fixes (upstream, via mcp-datahub v1.4.1–v1.4.3)

These fixes shipped in prior mcp-datahub patch releases that are included in this release:

• raise_incident — Fixed GraphQL mutation sending resourceUrns as an array of objects instead of the expected singular resourceUrn: String! field
• set_structured_property — Fixed wrong GraphQL field name (propertyUrn vs structuredPropertyUrn), missing selection set on non-scalar return type, and value serialization (raw values now wrapped in typed maps like {"stringValue": "..."})
• resolve_incident — Fixed GraphQL input type mismatch (UpdateIncidentStatusInput! → IncidentStatusInput!)
• update_description / add_tag / remove_tag on domains, glossary terms, and glossary nodes — REST API does not register these aspects as writable; operations now route through GraphQL mutations instead
