+### Smithery entrypoint
+
+Smithery deployments build from source using the Smithery CLI. The CLI discovers the TypeScript entrypoint from `package.json#module`, so this repository intentionally points `module` to `src/smithery.ts`. The npm runtime entrypoint is defined by `exports` and targets the compiled `build/` output.
