yarr-mcp

yarr-mcp

Node launcher for the yarr MCP and CLI binary.

yarr-mcp is the npm package name because the shorter yarr package name is already occupied. The installed command is still yarr, and the GitHub repository remains jmagar/yarr.

npx -y yarr-mcp mcp

Install globally when you want the command on PATH:

npm i -g yarr-mcp
yarr --version
yarr mcp

The package downloads the matching GitHub Release binary during postinstall. The npm package version and the yarr release tag are expected to match. Release automation publishes this package from the repository v* tag workflow; the GitHub repository must have an NPM_TOKEN secret with publish access.

The package name is yarr-mcp because the shorter yarr npm name is already occupied by an unrelated package. The installed command is still yarr.
