Install Prism in Claude Code
What you need first
- Claude Code, installed.
- Node.js, which
gives the
npxcommand the server starts with. - Your own value for
YOUR_TYPESAFE_API_KEY.
Steps
- Run this in a terminal, in the project folder. It adds the server for you in that
project; put
--scope userafterclaude mcp addto have it in every project.
claude mcp add --env TYPESAFE_API_KEY=YOUR_TYPESAFE_API_KEY --transport stdio prism -- npx -y @tulipe1735/[email protected] - Replace
YOUR_TYPESAFE_API_KEYwith your own value. - Start Claude Code and type
/mcp: the server is listed with its state.
Check it worked
Ask Claude Code: List the tools of prism.
If it does not start
- spawn npx ENOENT
- Node.js is not on the PATH that Claude Code sees. Install it, or write the
full path of
npxin the config. - The server starts, but its tools fail
- A
YOUR_…placeholder is still in the config, or its value is wrong.
