turn-mcp

Overview

turn-mcp-web is a self-hosted MCP server that transforms single agent requests into durable human-in-the-loop conversations. It provides tools like 'turn.wait' that pause execution and allow humans to respond through a browser console, with the same agent run continuing afterward. This approach maintains context across checkpoints, making it valuable for approvals, branching decisions, operator handoffs, review queues, and long-running workflows. The server supports multiple client connection methods including HTTP transport for IDE MCP clients, stdio for desktop clients, and a REST long-poll API for non-MCP frameworks.

FAQ

What does 'infinite conversation turns' mean?

It means maintaining context across multiple human-AI interactions within a single continuous agent execution, rather than starting a new conversation for each interaction.

What MCP tools are provided?

The server provides MCP tool aliases: `turn.wait`, `turn_wait`, and `turn` - all referring to the same pause-and-wait-for-human-reply functionality.

Can I use this with non-MCP frameworks?

Yes, it includes a REST long-poll API and a Python client for integrating with frameworks that don't support MCP directly.
