The pricing address redirects to a sales form\n\n### Glean (B)\n\nGood for: Agents working inside a company that already runs Glean and need answers from its documents, chats, tickets, code and people with each user's permissions applied.\n\nAhead on:\n- Schema \u0026 documentation, 93 against 78\n- Agent ergonomics, 80 against 71\n- Security \u0026 auth, 87 against 63\n- Maintenance \u0026 community, 85 against 71\n\nWatch for: No public price, trial or self-serve signup. Access starts with a demo request\n\n\n## Score by category\n\n| Category | Weight | Alation | Glean | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 61 | 60 | Alation +1 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 78 | 93 | Glean +15 |\n| Agent ergonomics | 13% (16.2 this run) | 71 | 80 | Glean +9 |\n| Security \u0026 auth | 14% (17.5 this run) | 63 | 87 | Glean +24 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 0 | 0 | even |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 71 | 85 | Glean +14 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 76 | 80 | Glean +4 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **60.3 · C** | **69.8 · B** | |\n\n## Facts side by side\n\n| Fact | Alation | Glean |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Alation, Inc. | Glean Technologies, Inc. |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | HTTP, Streamable HTTP, stdio | HTTP |\n| Auth | OAuth or key | OAuth or key |\n| Pricing | Paid | Paid |\n| x402 | no | no |\n| Licence | Proprietary service under Alation's Master Cloud Software Licence and Services Agreement.

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.\n\n**Glean.** Three public OpenAPI specs (Client, Indexing, Platform) regenerated almost daily, plus llms.txt and Markdown docs. No public price, trial or self-serve signup. Access starts with a demo request.\n\n## Before you call either\n\n### Alation\n\n1. 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\n2. Pin `alation-ai-agent-mcp==1.0.0rc3`. An unpinned install resolves to 0.12.0, which predates the catalogue search agent\n3. Call `catalog_context_search_agent` for catalogue questions. `alation_context` is deprecated and its description tells models not to call it directly\n4. Watch `X-Entitlement-Usage` on Aggregated Context API responses. The 2,000 free calls never reset, and a quota 429 is not retryable\n5. 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\n\n### Glean\n\n1. Get the backend host from the Glean admin. APIs answer at https://\u003cinstance\u003e-be.glean.com and MCP at that host under /mcp/\u003cserver-name\u003e\n2. Ask for a user-scoped token with only the scopes the task needs. A global token can impersonate whoever `X-Glean-ActAs` names\n3. Keep chat under 0.5 calls a second and search under 5, and back off on 429\n4. Call the Platform API's `/api/search` for typed filters, `page_size` up to 100 and problem+json errors\n5. Send `X-Glean-Exclude-Deprecated-After` in tests to catch fields due for removal\n\n## Questions\n\n### Which is better for AI agents, Alation or Glean?\n\nGlean scores 69.8 (B) on agent readiness against Alation's 60.3 (C), and leads in 5 of 7 scored categories.\n\n### Do Alation and Glean need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Alation and Glean without installing anything?\n\nAlation runs on your own machine, with no hosted endpoint listed. No hosted endpoint is listed for Glean.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/alation-vs-glean.json, and with the fewest tokens: https://www.anchorterminal.com/compare/alation-vs-glean.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"alation\", \"b\": \"glean\"}`.
