Building

npm run build

Note: Unlike typical Node.js projects, the build directory is committed to this repository to support direct npx execution without requiring users to build the project themselves.

Running in Development Mode

npm run dev -- --auth-token YOUR_SENTRY_TOKEN

Authentication

This server requires a Sentry authentication token to access the Sentry API. You can provide this token in two ways:

1. Using the --auth-token command-line option:

   mcp-sentry --auth-token YOUR_SENTRY_TOKEN

2. Using the SENTRY_TOKEN environment variable:

   SENTRY_TOKEN=YOUR_SENTRY_TOKEN mcp-sentry
