Access tokens last one hour, with a 30-day refresh token when the client registers that grant.

A person must sign in through a browser, the SOC 2 audit is unfinished, and the site's changelog stops at 13 July 2026.\n\n**Zapier MCP (agent actions).** 16 meta-tools in agentic mode, or managed mode with only the actions you pick. Connection tokens are long-lived and the docs allow them in the URL query string.\n\n## Before you call either\n\n### One\n\n1. Call `list_one_integrations` first and read each connection's `access` field. When the policy is `actions`, run those ids directly without calling `find_one_actions`\n2. Send every operation a task needs in one `find_one_actions` call, up to 10 `requests`, each a platform and a short intent with no IDs, names or message text\n3. When a document comes back as a digest, call `find_one_actions` again with `load` and a `section` name. Don't guess parameters the digest left out\n4. After a timeout on `execute_one_action`, check whether the write took effect before sending it again. No idempotency key is documented\n5. A 403 for a call outside the grant won't succeed on retry. Ask the user to widen the grant in the dashboard or reconnect\n\n### Zapier MCP (agent actions)\n\n1. Call discover_zapier_actions and enable_zapier_action before executing, discovery is free and execution costs two tasks\n2. Use execute_zapier_read_action for lookups, keep execute_zapier_write_action for changes\n3. Send the connection token in the `Authorization` header, never in the URL\n4. Count batch writes per item before starting, five rows is ten tasks\n\n## Questions\n\n### Which is better for AI agents, One or Zapier MCP (agent actions)?\n\nOne scores 66.6 (B) on agent readiness against Zapier MCP (agent actions)'s 58.1 (C), and leads in 5 of 7 scored categories. Zapier MCP (agent actions) leads on payments \u0026 pricing and transparency \u0026 trust.\n\n### Do One and Zapier MCP (agent actions) need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call One and Zapier MCP (agent actions) without installing anything?\n\nYes. One has a hosted endpoint at https://mcp.withone.ai/mcp and Zapier MCP (agent actions) at https://mcp.zapier.com/api/v1/connect.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/one-vs-zapier-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/one-vs-zapier-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"one\", \"b\": \"zapier-mcp\"}`.
