Max MCP Server (Digital Crew)

MCP server for Max, the AI sales agent from Digital Crew. Max is built for lead qualification, cold outreach, and pipeline growth—see the product story on max.digitalcrew.tech.

This repo hosts a Next.js app that exposes MCP tools over Streamable HTTP so Max (or any MCP-capable client) can read and update workspace profile settings against the Digital Crew backend API.

What it does

The server registers tools that proxy to Digital Crew’s workspace profile API (/api/v1/workspace-profile-settings):

Tool definitions and validation use Zod (features/workspace-profile/mcp/schema.ts). Registration lives under features/workspace-profile/mcp/.

Requirements

• Node.js (see Next.js 15 requirements)

• pnpm (see packageManager in package.json)

Configuration

Set these environment variables (e.g. in .env.local for local dev, or in your host’s env for production):

*If you omit these, callers must supply auth per request: Authorization: Bearer <token> on the MCP HTTP request, or the optional bearer_token argument on a tool call. Precedence is: tool bearer_token → MCP Authorization → env.

Getting started

pnpm install
# Create .env.local with DIGITALCREW_API_BASE_URL (and optional token vars)

pnpm dev

The MCP endpoint is:

• Local: http://localhost:3000/mcp

• Production: https://<your-deployment>/mcp

Point your MCP client at that URL using Streamable HTTP transport.

Optional: smoke-test with the bundled script

scripts/test-streamable-http-client.mjs lists tools via Streamable HTTP. It expects the @modelcontextprotocol/sdk client package available in your environment (install it if the script is not runnable yet):

node scripts/test-streamable-http-client.mjs http://localhost:3000

Note: SSE is currently disabled in app/mcp/route.ts (disableSse: true). The older scripts/test-client.mjs (SSE) is not aligned with the default setup unless you enable SSE and Redis per Vercel’s MCP pattern.

Stack

• Next.js App Router

• mcp-handler (Vercel MCP adapter)

• Zod for tool input schemas

Deploying on Vercel

• Enable Fluid compute for efficient execution.

• Adjust maxDuration in app/mcp/route.ts if your plan allows (e.g. up to 800s on Pro/Enterprise).

• SSE: If you switch disableSse to false, attach Redis and set REDIS_URL as required by the adapter. See also the Next.js MCP template.
