Protect MCP Setup

protect-mcp-setup

Configure Cedar policy enforcement and Ed25519 signed receipts for Claude Code tool calls. Use when setting up projects that need cryptographic audit trails, policy-gated tool execution, or compliance-ready evidence of agent actions.

Install

Run this in your project folder. It works with Claude Code, Cursor, Codex and dozens of other agents.

$ npx skills add wshobson/agents --skill protect-mcp-setup

Needs Node.js. Add -g to install for every project, or -a claude-code to skip the agent picker.

How to use Protect MCP Setup

Once it's installed, Claude reads this skill on its own whenever a request matches what it's for, so you don't have to mention it by name. In Claude Code you can also run it directly by typing /protect-mcp-setup.

It contains no scripts, only instructions and reference files, so it can't run code on its own.
