# Alation (slim) > Alation is a hosted data catalogue for tables, queries, BI reports, lineage and data quality. Agents reach it through REST APIs, a natural-language Aggregated Context API, a Python agent SDK and an MCP server on each cloud instance. - Full: https://www.anchorterminal.com/tools/alation.md (~8,350 tokens) · this version ~1,880 tokens · JSON https://www.anchorterminal.com/tools/alation.json · canonical https://www.anchorterminal.com/tools/alation - Index: https://www.anchorterminal.com/llms.txt · API: https://www.anchorterminal.com/api/v1/index.json · Updated: 2026-10-09 **C · 60.3/100 · rank #472 of 842 · #7 in Company knowledge & data catalogues · not agent-ready · confidence medium** Assessment: Each API has an OpenAPI 3.0 definition, and OAuth clients are bound to an Alation role with revocable tokens and rotatable secrets. Access needs a sales contract, since no price, trial or self-serve sign-up is published. The agent SDK and local MCP server have stayed at a release candidate since 14 January 2026. ## Facts - Kind: HTTP API · vendor: Alation, Inc. · category: Company knowledge & data catalogues · legal entity: Alation, Inc. · provenance 86/100 - Local only (HTTP, Streamable HTTP, stdio): pypi `alation-ai-agent-mcp`, pypi `alation-ai-agent-sdk`, pypi `allie-sdk` - Auth: OAuth or key · pricing: Paid · x402: no · licence: Proprietary service under Alation's Master Cloud Software Licence and Services Agreement.

Snippets in the full twin. ## Before you call it 1. Ask a Server Admin to register an OAuth client application with the lowest role that fits. Only admins can create one, and the secret is shown once 2. Pin `alation-ai-agent-mcp==1.0.0rc3`. An unpinned install resolves to 0.12.0, which predates the catalogue search agent 3. Call `catalog_context_search_agent` for catalogue questions. `alation_context` is deprecated and its description tells models not to call it directly 4. Watch `X-Entitlement-Usage` on Aggregated Context API responses. The 2,000 free calls never reset, and a quota 429 is not retryable 5. Page with `limit` and `skip` and follow `X-Next-Page`. The BI Source API uses `offset`, and one call returns at most 1,000 objects ## Connect ```bash uv pip install alation-ai-agent-mcp==1.0.0rc3 ``` Full config and headless snippets are in the full page.
