No published rate limits of Apideck's own, only connector limits mirrored in headers.\n\n**Xero API + MCP.** Granular OAuth scopes, such as accounting.reports.profitandloss.read, required for apps created from 29 April 2026. Developer docs, including the per-minute rate limits, only render with JavaScript.\n\n## Before you call either\n\n### Apideck Accounting API + MCP\n\n1. Stay in dynamic mode and search for tools. Static mode loads all 362 schemas\n2. Start the MCP with --lock-identity (or ?lock_identity=true) when one agent serves one customer\n3. Read x-downstream-ratelimit-remaining before fanning out, and wait until x-downstream-ratelimit-reset after a 429\n4. List before you retry a create that timed out. Writes aren't idempotent and there's no idempotency key\n5. Pass fields= on list calls to cut the response to the columns you need\n\n### Xero API + MCP\n\n1. Send xero-tenant-id on every call. The token alone doesn't name the organisation\n2. A bill is an Invoice with Type ACCPAY, a sales invoice is ACCREC. There's no separate bills endpoint\n3. Send an Idempotency-Key on creates so a retry after a timeout doesn't post twice\n4. Use If-Modified-Since and pageSize up to 100 to stay inside 1,000 calls a day on Starter\n5. Set XERO_SCOPES to read scopes only when the agent shouldn't write. The MCP still lists its write and delete tools\n\n## Other comparisons with Apideck Accounting API + MCP or Xero API + MCP\n\n- [Apideck Accounting API + MCP vs FreeAgent API](https://www.anchorterminal.com/compare/apideck-accounting-vs-freeagent.md)\n- [Apideck Accounting API + MCP vs FreshBooks API](https://www.anchorterminal.com/compare/apideck-accounting-vs-freshbooks.md)\n- [Apideck Accounting API + MCP vs QuickBooks Online API + MCP](https://www.anchorterminal.com/compare/apideck-accounting-vs-quickbooks-online.md)\n- [FreeAgent API vs Xero API + MCP](https://www.anchorterminal.com/compare/freeagent-vs-xero.md)\n- [FreshBooks API vs Xero API + MCP](https://www.anchorterminal.com/compare/freshbooks-vs-xero.md)\n- [Merge Accounting API vs Xero API + MCP](https://www.anchorterminal.com/compare/merge-accounting-vs-xero.md)\n- [QuickBooks Online API + MCP vs Xero API + MCP](https://www.anchorterminal.com/compare/quickbooks-online-vs-xero.md)\n- [Rutter Accounting API vs Xero API + MCP](https://www.anchorterminal.com/compare/rutter-vs-xero.md)\n- [Apideck Accounting API + MCP vs Invoice Ninja API](https://www.anchorterminal.com/compare/apideck-accounting-vs-invoice-ninja.md)\n- [Invoice Ninja API vs Xero API + MCP](https://www.anchorterminal.com/compare/invoice-ninja-vs-xero.md)\n- [Apideck Accounting API + MCP vs Merge Accounting API](https://www.anchorterminal.com/compare/apideck-accounting-vs-merge-accounting.md)\n- [Apideck Accounting API + MCP vs Rutter Accounting API](https://www.anchorterminal.com/compare/apideck-accounting-vs-rutter.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-04", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "Apideck Accounting API + MCP vs Xero API + MCP", "url": "" } ], "description": "Apideck Accounting API + MCP has a score of 73.2 (BB) against Xero API + MCP's 67.4 (B).
