The eight default tools carry about 26,000 characters of descriptions, and search and get_lineage each repeat the same 3,063-character filter grammar.\n\n**OpenMetadata.** MCP built into every instance at /mcp and on by default since 2.0, with nothing extra to install. The 16 default tools take about 50,000 characters of definitions, 12,285 of them for search_metadata alone.\n\n## Before you call either\n\n### DataHub\n\n1. Start keyword queries with `/q` and pass filters as one string, such as `entity_type = dataset AND platform = snowflake`\n2. Call `search` with `num_results=0` first to get the tags, glossary terms, platforms and domains in use\n3. Page with `offset`. `num_results` is capped at 50\n4. Expect no write tools unless the operator set `TOOLS_IS_MUTATION_ENABLED=true`, and create tags and terms before `add_tags` or `add_terms` refers to them\n5. Use https://mcp.datahub.com/mcp with OAuth only on DataHub Cloud v1.0.2 or later. DataHub Core needs the local server and a personal access token\n\n### OpenMetadata\n\n1. Set `entityType` for data-quality questions. testCase and testSuite are outside the default search scope\n2. Match a table's tests on `originEntityFQN`, not `entityFQN`. Column-level tests store the column's FQN there\n3. Read several known entities in one `search_metadata` call with a `terms` clause on `fullyQualifiedName` plus `fields`\n4. Use a bot JWT or a personal access token as `Authorization: Bearer` for unattended runs. OAuth needs a browser sign-in\n5. Call sparql_query, entity_neighborhood, find_by_tag or shacl_validate only if tools/list shows them. They appear only when the operator enabled RDF\n\n## Other comparisons with DataHub or OpenMetadata\n\n- [Atlan vs DataHub](https://www.anchorterminal.com/compare/atlan-vs-datahub.md)\n- [Atlan vs OpenMetadata](https://www.anchorterminal.com/compare/atlan-vs-openmetadata.md)\n- [DataHub vs Marmot](https://www.anchorterminal.com/compare/datahub-vs-marmot.md)\n- [Marmot vs OpenMetadata](https://www.anchorterminal.com/compare/marmot-vs-openmetadata.md)\n- [DataHub vs Guru](https://www.anchorterminal.com/compare/datahub-vs-guru.md)\n- [Guru vs OpenMetadata](https://www.anchorterminal.com/compare/guru-vs-openmetadata.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-05", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "DataHub vs OpenMetadata", "url": "" } ], "description": "OpenMetadata has a score of 66.9 (B) against DataHub's 59.5 (C).
