Mcp Seatbelt

Overview

Mcp Seatbelt is a Model Context Protocol (MCP) server: MCP runtime security proxy. Blocks dangerous AI agent tool calls with a policy engine. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the npm package @kryptosai/mcp-seatbelt speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.7.0, published under the MIT license, with source at KryptosAI/mcp-seatbelt on GitHub.

You'll find Mcp Seatbelt in the AI & Agents category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
