Callable addresses a trust problem that no amount of technical workarounds can fix: platforms detect automation and shadowban or block synthetic activity. The solution isn't better spoofing — it's actual humans. Callable provides an API (and MCP server) that lets AI agents delegate tasks requiring human authenticity to a pool of real operators. Supported task types include outbound phone calls, user-generated content videos, social media posts, account verifications, and lead enrichment. The agent submits a task, a human operator completes it, and the result is delivered back to the agent automatically — no manual handoff, no polling loop. Currently 27 operators are available and the service is live on the MCP Registry, making it directly accessible from Claude and other MCP-compatible agent frameworks. Built for agent developers who hit the wall where automation ends and human trust signals begin.
