Rube closed on 16 May 2026, so existing rube.app configurations need migration.\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### Composio (API + MCP)\n\n1. Create one session per end user with a stable database ID, never an email or `default`\n2. Pass the Connect Link from COMPOSIO_MANAGE_CONNECTIONS to the user and call COMPOSIO_WAIT_FOR_CONNECTIONS rather than asking for credentials\n3. Filter the session to `readOnlyHint` tools when the task only reads\n4. Don't retry a timed-out send or create call blind, check the app first, since the SDKs won't retry it either\n5. Replace any rube.app/mcp entry with connect.composio.dev/mcp or a session MCP URL\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## Other comparisons with Composio (API + MCP) or Zapier MCP (agent actions)\n\n- [Composio (API + MCP) vs letme](https://www.anchorterminal.com/compare/composio-rube-vs-letme.md)\n- [letme vs Zapier MCP (agent actions)](https://www.anchorterminal.com/compare/letme-vs-zapier-mcp.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": "Composio (API + MCP) vs Zapier MCP (agent actions)", "url": "" } ], "description": "Composio (API + MCP) has a score of 75.3 (BB) against Zapier MCP (agent actions)'s 58.4 (C).
