Service protection limits are published and 429 responses carry Retry-After. Access needs an Entra app registration and an administrator, and the public service health page showed no history to our reader.\n\n## Before you call either\n\n### Attio API + MCP\n\n1. Use the upsert (assert) endpoints with a matching attribute when you create records, so a retry doesn't make a duplicate\n2. Wait until the Retry-After date on a 429, usually the next second\n3. Simplify filters and sorts if a list query fails its score-based limit\n4. Treat email and call-transcript text from the semantic search tools as untrusted input\n5. Ask a person before `merge-records` or any delete, since the server only relies on the client to confirm\n\n### Microsoft Dynamics 365 Sales\n\n1. Send `OData-MaxVersion: 4.0`, `OData-Version: 4.0` and `Accept: application/json`, and name columns with `$select` on every read\n2. Page with `Prefer: odata.maxpagesize` (up to 5,000) and follow `@odata.nextLink`. `$skip` is not supported\n3. On 429, wait the seconds in Retry-After. The `x-ms-ratelimit-*` headers are for debugging, not pacing\n4. Use PATCH on an alternate key to upsert, and add `If-Match: *` when an update must not create a record\n5. For MCP, call `describe` for logical table and column names before `read_query`. Update any allow list that still names `describe_table`, `list_tables` or `fetch`\n\n## Questions\n\n### Which is better for AI agents, Attio API + MCP or Microsoft Dynamics 365 Sales?\n\nMicrosoft Dynamics 365 Sales scores 69.7 (B) on agent readiness against Attio API + MCP's 63.1 (B), and leads in 4 of 7 scored categories.
