Add my server

Install mcp-sanctions in Claude Code

What you need first

  • Claude Code, installed.
  • uv, which gives the uvx command the server starts with.
  • Your own value for YOUR_MCP_SANCTIONS_API_KEY.

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 MCP_SANCTIONS_API_KEY=YOUR_MCP_SANCTIONS_API_KEY --transport stdio mcp-sanctions -- uvx atomno-mcp-sanctions==0.1.1
  1. Replace YOUR_MCP_SANCTIONS_API_KEY with your own value.
  2. Start Claude Code and type /mcp: the server is listed with its state.

Check it worked

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

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.
