Rube closed on 16 May 2026, so existing rube.app configurations need migration.\n\n**Unified.to MCP Server.** Every previewed tool carries a typed input schema and read-only, destructive and idempotent annotations, and the list can be narrowed by permission or tool name. The default credential is a workspace API key that reaches every connection, and the SSE transport was removed on 23 September 2026 in the changelog entry that announced it.\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### 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## Questions\n\n### Which is better for AI agents, Composio (API + MCP) or Unified.to MCP Server?\n\nComposio (API + MCP) scores 75.1 (BB) on agent readiness against Unified.to MCP Server's 61.9 (C), and leads in 6 of 7 scored categories.\n\n### Do Composio (API + MCP) and Unified.to MCP Server need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Composio (API + MCP) and Unified.to MCP Server without installing anything?\n\nYes. Composio (API + MCP) has a hosted endpoint at https://backend.composio.dev/api/v3.1 and Unified.to MCP Server at https://mcp-api.unified.to/mcp.\n\n### Are Composio (API + MCP) and Unified.to MCP Server open source?\n\nComposio (API + MCP) is open source (MIT).
