Installation - @phake/mcp

Requirements

Bun 1.x or Node.js 20+
Wrangler CLI — required for Cloudflare Workers deployments
A Cloudflare account with Workers and KV access — required for Worker deployments

Install the package

npm install @phake/mcp

bun add @phake/mcp

yarn add @phake/mcp

pnpm add @phake/mcp

Package exports

@phake/mcp exposes three entry points:

Export	Import path	Description
Core	`@phake/mcp`	`defineTool`, `createMCPServer`, and all helpers
Worker runtime	`@phake/mcp/runtime/worker`	Cloudflare Workers adapter internals
Node runtime	`@phake/mcp/runtime/node`	Node.js adapter internals (experimental)

Most projects only need the core entry point. The runtime exports are used internally by the adapters and are available if you need lower-level access.

import { defineTool, createMCPServer } from "@phake/mcp";

Peer dependencies

The following peer dependencies are optional. Install them only if you use the corresponding runtime or feature:

Package	When required
`hono`	Node.js runtime (`node-hono` template)
`@hono/node-server`	Node.js runtime (`node-hono` template)
`better-sqlite3`	`SqliteSessionStore` storage backend

If you scaffold a project with bun create @phake/mcp, the template’s package.json already lists the correct peer dependencies for your chosen runtime. You only need to install them manually when adding @phake/mcp to an existing project.

Install peer dependencies as needed:

# Node.js runtime
npm install hono @hono/node-server

# SQLite session store
npm install better-sqlite3

# Node.js runtime
bun add hono @hono/node-server

# SQLite session store
bun add better-sqlite3
