Implementation Reference

• src/index.ts:81-106 (handler)

  The implementation of the 'version' tool, which wraps `npm version` to bump package versions.

  server.tool(
    "version",
    "Bump the package version",
    {
      path: z.string().describe("Absolute path to the package directory"),
      bump: z
        .enum(["patch", "minor", "major", "prepatch", "preminor", "premajor", "prerelease"])
        .describe("Version bump type"),
      preid: z.string().optional().describe("Prerelease identifier (e.g. alpha, beta)"),
      noGitTag: z.boolean().optional().describe("Skip git tag creation"),
    },
    async ({ path, bump, preid, noGitTag }) => {
      const args = ["version", bump];
      if (preid) args.push("--preid", preid);
      if (noGitTag) args.push("--no-git-tag-version");
      try {
        const { stdout } = await run(args, path);
        return { content: [{ type: "text", text: stdout.trim() }] };
      } catch (e: any) {
        return {
          content: [{ type: "text", text: `Error: ${e.stderr || e.message}` }],
          isError: true,
        };
      }
    },
  );
