Send `Authorization: Bearer \u003ctoken\u003e` to `https://api.capsulecrm.com/api/v2`. Projects use the old name in paths, `/kases`\n2. Follow the `Link` header for the next page. `perPage` goes up to 100 and the default is 50\n3. On 429, wait until the epoch time in `X-RateLimit-Reset`. The docs suggest one second between calls\n4. Ask for the `read` scope when the task only reads. A write with a read-only token answers 403 with `insufficient_scope`\n5. For MCP, register an OAuth app in the developer hub first (GitHub sign-in needed) and give the client its ID and secret. Personal API tokens are refused\n\n### Close API + MCP\n\n1. Connect with `Close-Scope: mcp.read` unless the job needs writes, and `mcp.write_safe` if it only creates\n2. Sleep for the `reset` value in the `RateLimit` header after a 429, which the docs say beats `retry-after`\n3. Use cursors through advanced filtering or the event log for large pulls, since `_skip` has a per-resource ceiling\n4. Search the lead before `create_lead`, because there's no idempotency key and a retry makes a duplicate\n5. Expect `create_draft_email` to leave a draft, and tell the user to send it from Close\n\n## Questions\n\n### Which is better for AI agents, Capsule CRM or Close API + MCP?\n\nClose API + MCP scores 66.7 (B) on agent readiness against Capsule CRM's 55.7 (C), and leads in 3 of 7 scored categories.
