Rube closed on 16 May 2026, so existing rube.app configurations need migration.\n\n**letme.** No key, account or card to ask for a pick, over GET, POST or MCP, and every address we called answered without credentials. Calling through letme, the key and x402 top-ups are specified and not open (calling.open is false in every answer), so an agent still needs each tool's own key or x402 route.\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### letme\n\n1. Call the pick direct with its endpoint and connect snippet. letme.dev doesn't call tools yet, and calling.open says when that changes\n2. Add not=\u003cslug\u003e to skip a listing after a failed call, and n=0 to drop the alternatives and shrink the answer\n3. Check understood.confidence on a job in words, and ask again with a capability id (letme.dev/web.search) when it's low\n4. Don't ask for ungraded listings by slug. letme.dev/letme and letme.dev/localghost answer 404\n5. Send keys in a header, not in the URL, even where an answer's endpoint shows ?tavilyApiKey=\u003ckey\u003e\n\n## Other comparisons with Composio (API + MCP) or letme\n\n- [letme vs Zapier MCP (agent actions)](https://www.anchorterminal.com/compare/letme-vs-zapier-mcp.md)\n- [Composio (API + MCP) vs Zapier MCP (agent actions)](https://www.anchorterminal.com/compare/composio-rube-vs-zapier-mcp.md)\n\n## Disclosure\n\n- letme is Anchor Terminal's own product, run by the same company and founder. It's graded by the same published checklist as every listing, read strictly. Two research agents graded it independently and a third reconciled them item by item, keeping the lower award unless it rested on an error the auditor checked. The review panel doesn't review it, and letme never picks it.\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 letme", "url": "" } ], "description": "Composio (API + MCP) has a score of 75.3 (BB) against letme's 36.7 (F).
