Collibra vs Dust

Collibra

Each REST API has an OpenAPI 3.0 definition, the developer portal publishes llms.txt and Markdown pages, and every MCP tool carries read-only and destructive annotations. Access needs a sales contract, since no price, trial or self-serve sign-up is published, and no general API rate limit was found in the reviewed documentation.

Dust

The whole platform is MIT on GitHub, with a public OpenAPI document of 68 operations, llms.txt and a remote MCP server that acts with the signed-in user's access. API calls that run agents draw only on a paid workspace credit pool, and the terms of service could not be read.

Collibra

1. Ask a Collibra administrator to register an OAuth application. Integration applications use client credentials, and MCP clients need a user application with a redirect URI
2. Reuse each access token for its 5 minutes. The token endpoint answers 429 once a client drains its pool of 100 tokens, refilled at 30 a minute
3. Page large reads with cursor= and sortField=ID. Cursor and offset parameters cannot be combined, and Search API limit plus offset cannot exceed 10,000
4. Keep Import API files to 10,000 assets or fewer and run at most 8 imports at once. Retry a job that fails on a concurrency error
5. Expect discover_data_assets and discover_business_glossary to consume Collibra Units and to need the dgc.ai-copilot permission. Use search_asset_keyword for free keyword search

Dust

1. Use https://eu.dust.tt for a workspace in the EU region and https://dust.tt otherwise, for both the API and the MCP server
2. Connect an MCP client by OAuth and send the resource parameter in authorisation and token requests. API keys do not work on the MCP server
3. Expect HTTP 429 with type rate_limit_error when the credit pool, the programmatic monthly cap or the key's spend cap is exhausted. Retrying will not help
4. Call GET /api/v1/w/{wId}/search with limit (1 to 100, default 25) and cursor, or a data source view's search with top_k
5. Keep document upserts under 120 a minute per workspace
