Callable
Delegate agent-stuck work to verified humans through MCP when automation cannot finish verification, ops, or real-world steps.
Overview
Callable is an MCP server for the Build phase that lets AI agents delegate tasks to real humans via a streamable HTTP API.
What is this MCP server?
- Remote MCP endpoint at https://getcallable.dev/api/mcp (streamable HTTP)
- API for AI agents to delegate tasks to real humans
- Version 1.0.0 with GitHub source callable-task-deck
- Supports human handoff when agents hit physical, legal, or judgment limits
- Fits operate and grow scenarios for support tickets and lifecycle tasks agents cannot close alone
- Remote MCP URL https://getcallable.dev/api/mcp
- Server version 1.0.0
What problem does it solve?
Autonomous agents fail on real-world steps that need a person, leaving solo founders to manually rescue every blocked run.
Who is it for?
Indie builders prototyping agent workflows that need occasional human verification, ops, or field actions.
Skip if: Fully offline CLI tools or products that never require a human executor.
What do I get? / Deliverables
Agents enqueue human-completed tasks through MCP so mixed human-agent workflows finish without constant founder intervention.
- Human-executed task outcomes reachable from agent MCP calls
- Production remote endpoint for mixed autonomous and manual workflows

Journey fit
Canonical shelf is Build because human-in-the-loop delegation is agent infrastructure you integrate while designing autonomous workflows. Agent-tooling captures Callable as remote MCP (streamable HTTP) that extends what your coding agent can legally and practically execute.
How it compares
Human-delegation MCP API, not an LLM prompt library or local code execution sandbox.
Common Questions / FAQ
Who is Callable for?
Solo builders and agent developers who need a managed way to pass tasks from MCP clients to real human workers.
When should I use Callable?
When your agent hits steps only a person can perform and you want that escalation inside the same MCP tool chain.
How do I add Callable to my agent?
Add the remote MCP server URL https://getcallable.dev/api/mcp with streamable HTTP transport in your agent’s MCP configuration per Callable docs.
