Connection tokens are long-lived and the docs allow them in the URL query string.\n\n## Before you call either\n\n### Unified.to MCP Server\n\n1. Use the host for the workspace's region. US is `mcp-api.unified.to`, EU is `mcp-api-eu.unified.to` and AU is `api-au.unified.to`. A credential on another region's host resolves to not found\n2. Send the key as `Authorization: Bearer \u003ckey\u003e` and put `connection=\u003cid\u003e` in the URL. Without `connection` the server lists workspace management tools, not the customer's data tools\n3. Pass `tools` or `permissions` in the URL before listing. An unfiltered connection can list dozens of tools with large output schemas\n4. Expect HTTP 429 on tool calls since 23 September 2026. Unified does not queue or retry, so back off and retry yourself\n5. Page with `limit` (100 at most on most endpoints) and `offset`, and stop when a page returns fewer records than `limit`\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, Unified.to MCP Server or Zapier MCP (agent actions)?\n\nUnified.to MCP Server scores 61.9 (C) on agent readiness against Zapier MCP (agent actions)'s 58.1 (C), and leads in 4 of 7 scored categories. Zapier MCP (agent actions) leads on security \u0026 auth, payments \u0026 pricing and transparency \u0026 trust.\n\n### Do Unified.to MCP Server 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 Unified.to MCP Server and Zapier MCP (agent actions) without installing anything?\n\nYes.
