mcp-server-template

A template for building a TypeScript MCP server. It ships a reusable carcass — typed fetch client (timeouts, retries, backoff), rate limiting, TTL cache, OAuth token store, structured errors, leveled logging, MCP tool-result helpers — plus build tooling, node:test setup, .mcpb packaging and GitHub Actions CI/release.

The server speaks standard MCP over stdio, so it works with any MCP client (Claude Desktop/Code, Cursor, VS Code, Cline, …).

Use it

Click Use this template on GitHub (or copy this directory), then follow the checklist in TEMPLATE.md. In short: rename, edit src/config.ts, add your src/clients/ and src/tools/, and update the manifest and docs. The included search tool is a placeholder to delete.

Develop

npm install
npm run build        # type-check + bundle to dist/index.js
npm test             # node:test (mocked, offline)
npm run lint
npm run format
npm run check:api    # live upstream health-check (add your endpoints)
npm run inspector    # run under the MCP Inspector

Runtime requires Node ≥ 20. Contributor/agent guidance lives in AGENTS.md (the single source of truth; CLAUDE.md just links to it).

Updating

Document how users update your server (keep this section in the generated repo):

• .mcpb bundle: download the new bundle from the releases page and reinstall.

• From source: git pull && npm ci && npm run build.

• npx (if published): unpinned npx -y <package> fetches the latest next run.

Tell users to Watch → Releases, and keep the CHANGELOG current.
