mcp-data-platform v1.50.0 — Advanced DataHub Search & Connection Editor Fixes

Advanced DataHub Search with Column-Level Filtering (#289)

Upgrades mcp-datahub to v1.8.0, switching the search backend from the basic search GraphQL endpoint to DataHub's searchAcrossEntities API. Agents can now search for datasets by column name, column-level tags, glossary terms, and more — without scanning every schema individually.

Simple search (unchanged):

datahub_search(query: "revenue", entity_type: "DATASET")

Search by column name:

datahub_search(
  query: "*",
  filters: [{ field: "fieldPaths", values: ["email"], condition: "CONTAIN" }]
)

Multi-type search with filters:

datahub_search(
  query: "customer",
  types: ["DATASET", "DASHBOARD"],
  filters: [
    { field: "platform", value: "urn:li:dataPlatform:trino" },
    { field: "tags", values: ["urn:li:tag:deprecated"], negated: true }
  ]
)

New tool parameters

Parameter	Description
types	Search across multiple entity types (e.g., ["DATASET", "DASHBOARD"])
filters	Advanced field-level filters (AND'd together)
mode	Search strategy: keyword (default) or semantic

Filter fields reference

Field	Matches
fieldPaths	Column/schema field names
fieldTags	Column-level tags
fieldGlossaryTerms	Column-level glossary terms
fieldDescriptions	Column-level descriptions
platform	Data platform (URN)
domains	Domain (URN)
owners	Owner (URN)
tags	Entity-level tags
glossaryTerms	Entity-level glossary terms
typeNames	Entity subtypes

Semantic layer changes

• SearchFilter type extended with EntityTypes, Mode, and Filters fields
• New FieldFilter type for arbitrary field-level filter criteria
• DataHub adapter switched from Search to SearchAcrossEntities / SemanticSearch
• Legacy filter fields (Platform, Tags, Domain, Owner) mapped to DataHub equivalents for backward compatibility
• Mode comparison is case-insensitive

Connection Editor Fixes (#288)

Fixes several issues in the admin connection editor UI, verified against the running dev environment.

• S3 path-style toggle: UI read force_path_style but the backend config key is use_path_style — toggle always showed OFF. Fixed key alignment in S3ConfigForm.
• Runtime config keys in detail view: redactConnectionConfig() now strips platform-injected keys (elicitation, progress_enabled) so only user-configured values appear in the connection config table.
• Description empty for file-only connections: File-sourced connections store description inside the config map, but the editor only read the top-level connection.description. Added fallback to config.description.
• Missing Schema field: Added "Default Schema" field to the Trino connection editor alongside "Default Catalog".
