I have implemented the Notion MCP using the Vercel AI SDK like this:
const mcpClient = await experimental_createMCPClient({ transport: new Experimental_StdioMCPTransport({ command: 'npx', args: ['-y', '@notionhq/notion-mcp-server'], env: { OPENAPI_MCP_HEADERS: JSON.stringify({ Authorization: `Bearer ACCESS_TOKEN`, 'Notion-Version': '2022-06-28', }), }, }),});const tools = await mcpClient.tools();Then I pass the tools to the Vercel AI SDK. The code is located inside a Vercel Function (Next.js)
It works well in my local environment but when I deploy to Vercel I have the following error:
npm error code ENOENTnpm error syscall mkdirnpm error path /home/sbx_user1051npm error errno ENOENTnpm error enoent Invalid response body while trying to fetch https://registry.npmjs.org/@notionhq%2fnotion-mcp-server: ENOENT: no such file or directory, mkdir '/home/sbx_user1051'npm error enoent This is related to npm not being able to find a file.npm error enoentnpm noticenpm notice New major version of npm available! 10.9.2 -> 11.4.1npm notice Changelog: https://github.com/npm/cli/releases/tag/v11.4.1npm notice To update run: npm install -g npm@11.4.1npm notice
