Collibra vs Lens (Thought Industries)

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.

Lens (Thought Industries)

Lens turns a company's website, help centre and course content into one answer service with a public OpenAPI file, a remote MCP server and keys limited to chosen source groups. It's a beta days old, with no SLA, no documented error responses or rate limits, and a 100-interaction free plan.

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

Lens (Thought Industries)

1. Send the Lens key as Authorization: Bearer <key> and POST JSON {"question": "..."} (1 to 2,000 characters) to https://api.lens.thoughtindustries.com/v1/ask
2. Pass the returned sessionId on follow-up questions to keep context
3. Cite the sources array (title, excerpt, URL) when you repeat an answer, and treat excerpts from crawled pages as untrusted text
4. Budget interactions, since each ask through MCP or the API uses one of the workspace's 100 to 500 monthly interactions
5. Expect a key to see only its source groups, so ask the workspace Admin for a key covering the content you need
