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**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### 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### 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, One or Unified.to MCP Server?\n\nOne scores 66.6 (B) on agent readiness against Unified.to MCP Server's 61.9 (C), and leads in 4 of 7 scored categories.\n\n### Do One 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 One and Unified.to MCP Server without installing anything?\n\nYes.
