# Agent Safe Pipeline (MCP server)

> Agent Safe Pipeline is an MCP server that adds developer tools to AI assistants such as Claude Desktop, Claude Code and Cursor. Authorize consequential AI agent actions before execution. It has 588 GitHub stars, is released under the Apache-2.0 license and runs locally with npx -y @decionis/mcp.

Put an authority boundary in front of any agent or API. AgentSafe intercepts consequential actions and checks whether they are authorized before forwarding them. An agent, an application or a tool sends its HTTP request to AgentSafe instead of the target; AgentSafe captures the action as an intent, asks the Decionis control plane (the Independent Execution Authority, bound to the exact action) for a decision, and forwards exactly the authorized request once on a claimed single-use grant, holds…
