Which integrations are available for this server?

Allows exposing Hono API endpoints as MCP tools, enabling AI models to programmatically discover and interact with routes, parameters, and request bodies defined within a Hono application.

How do I use Hono MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Hono MCP Server list all users" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

MCP Server for Hono

Expose your Hono API endpoints as MCP tools.

Usage

import { Hono } from "hono"; import { mcp, describe } from "hono-mcp-server"; const app = new Hono() .get( "/users", describe("List all users", (c) => c.json([{ id: 1, name: "Alice" }])), ) .get( "/users/:id", describe("Get user by ID", (c) => c.json({ id: c.req.param("id") })), ) .post( "/users", describe("Create a user", async (c) => c.json(await c.req.json(), 201)), ); export default mcp(app, { name: "Users API", version: "1.0.0", });

This adds an /mcp endpoint that exposes your routes as MCP tools.

Options

mcp(app, { name: "API Name", // required version: "1.0.0", // required description: "...", // optional instructions: "...", // optional mcpPath: "/mcp", // optional, default: "/mcp" codemode: false, // optional, see below });

Codemode

Instead of exposing individual routes as tools, codemode exposes search and execute tools for dynamic API interaction. Requires Cloudflare Worker Loader.

export default mcp(app, { name: "API", version: "1.0.0", codemode: true, });
