Install Guardrly in Claude Code

What you need first

• Claude Code, installed.
• uv, which gives the uvx command the server starts with.
• Your own values for YOUR_GUARDRLY_API_KEY,YOUR_HMAC_SECRET.

Steps

1. Run this in a terminal, in the project folder. It adds the server for you in that project; put --scope user after claude mcp add to have it in every project.

claude mcp add --env GUARDRLY_API_KEY=YOUR_GUARDRLY_API_KEY --env HMAC_SECRET=YOUR_HMAC_SECRET --transport stdio guardrly-mcp -- uvx guardrly==0.1.3

2. Replace YOUR_GUARDRLY_API_KEY,YOUR_HMAC_SECRET with your own values.
3. Start Claude Code and type /mcp: the server is listed with its state.

Check it worked

Ask Claude Code: List the tools of guardrly-mcp.

If it does not start

spawn uvx ENOENT

uv is not on the PATH that Claude Code sees. Install it, or write the full path of uvx in the config.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.
