How to access Hono Context from within @hono/mcp tool definition

[abegehr]

I'm building with https://www.npmjs.com/package/@hono/mcp

How can I access the Hono Context from within a tool call definition, to get things like env vars?

import { McpServer } from '@modelcontextprotocol/sdk/server/mcp.js'
import { StreamableHTTPTransport } from '@hono/mcp'
import { Hono } from 'hono'

const app = new Hono()

// Your MCP server implementation
const mcpServer = new McpServer({
  name: 'my-mcp-server',
  version: '1.0.0',
})

// Register tools
server.registerTool(
  "test",
  {
    title: "Test Tool",
    inputSchema: {},
    outputSchema: { … },
  },
  async () => {
    // ! How to access c (var and env) from here?
  },
);

app.all('/mcp', async (c) => {
  const transport = new StreamableHTTPTransport()
  await mcpServer.connect(transport)
  return transport.handleRequest(c)
})

export default app

@MathurAditya724 could you help me with this?

Use this - https://hono.dev/docs/middleware/builtin/context-storage

You will then be able to access the context variable from anywhere
