SRP Hub

An MCP (Model Context Protocol) server that exposes Hub API operations as tools for AI agents and MCP-compatible clients (e.g. Claude Desktop, GitHub Copilot, Cursor).

Overview

srp-hub-mcp acts as a bridge between AI assistants and the Hub API. It runs as a local stdio-based MCP server, allowing AI agents to interact with Hub resources — such as creating customer leads — using structured, validated inputs.

Requirements

• Node.js >= 18
• A valid HUB_API_TOKEN for authenticating against the Hub API

Installation

npm install
npm run build

Configuration

The server is configured via environment variables:

Variable	Required	Default	Description
HUB_API_TOKEN	Yes	—	Bearer token for Hub API auth
HUB_API_BASE	No	http://localhost:3001/v2	Base URL of the Hub API

Usage

Running directly

HUB_API_TOKEN=your_token node build/index.js

MCP client configuration

Add the following to your MCP client config (e.g. mcp.json or claude_desktop_config.json):

{
  "mcpServers": {
    "srp-hub-mcp": {
      "command": "npx",
      "args": ["srp-hub-mcp"],
      "env": {
        "HUB_API_TOKEN": "your_token_here",
        "HUB_API_BASE": "https://your-hub-api.example.com/v2"
      }
    }
  }
}

Running on Claude Desktop (Windows) via NPX

Step 1 — Install Node.js

Download and install Node.js >= 18 from https://nodejs.org.
Choose the LTS installer for Windows (.msi).

Verify the installation by opening Command Prompt or PowerShell:

node -v   # should print v18.x.x or higher
npm -v
npx -v

Step 2 — Install Claude Desktop

Download and install Claude Desktop from https://claude.ai/download.
Open it at least once so it creates its configuration folder.

Step 3 — Open the Claude Desktop config file

The configuration file is located at:

%APPDATA%\Claude\claude_desktop_config.json

You can open it quickly by pressing Win + R, pasting the path below, and pressing Enter:

%APPDATA%\Claude\claude_desktop_config.json

Or navigate manually:

C:\Users\<YourUsername>\AppData\Roaming\Claude\claude_desktop_config.json

If the file does not exist yet, create it as a new empty file in that folder.

Step 4 — Add the MCP server configuration

Open claude_desktop_config.json with any text editor (e.g. Notepad, VS Code) and add the block below.
If the file is already empty, paste the entire snippet. If it already has content, merge the mcpServers key.

{
  "mcpServers": {
    "srp-hub-mcp": {
      "command": "npx",
      "args": ["-y", "srp-hub-mcp"],
      "env": {
        "HUB_API_TOKEN": "your_token_here",
        "HUB_API_BASE": "https://your-hub-api.example.com/v2"
      }
    }
  }
}

Replace your_token_here with your real HUB_API_TOKEN and update HUB_API_BASE to point to your Hub API instance.
The -y flag in args tells NPX to skip the install confirmation prompt.

Step 5 — Save and restart Claude Desktop

1. Save claude_desktop_config.json.
2. Fully quit Claude Desktop (right-click the tray icon → Quit).
3. Re-open Claude Desktop.

Step 6 — Verify the integration

Start a new conversation in Claude Desktop and ask:

"What MCP tools do you have available?"

Claude should list post_customer among the available tools. You can then ask it to create a customer and it will use the Hub API through this server.

Troubleshooting

Problem	Solution
npx: command not found	Re-install Node.js and make sure it is added to PATH
Cannot find package 'srp-hub-mcp'	The package must be published to npm (npm publish) or use a local path (see below)
HUB_API_TOKEN errors	Double-check the token value in claude_desktop_config.json
Tools not appearing	Confirm the JSON is valid (no trailing commas) and restart Claude Desktop

Available Tools

post_customer

Creates a new customer (lead) in the Hub.

Field	Type	Required	Description
codigo	string	Yes	Unique customer code (max 40 chars)
tipo	number	Yes	Person type: 1=Juridical, 2=Physical, 3=Export
cnpjCpf	string	Yes	CPF (11 digits) or CNPJ (14 digits), numbers only
nomeFantasia	string	Yes	Trade name / display name (max 250 chars)
status	number	Yes	0=Inactive, 1=Active

Validation rules:

• If tipo is 2 (Física), cnpjCpf must be a valid 11-digit CPF.
• If tipo is 1 (Jurídica) or 3 (Exportação), cnpjCpf must be a valid 14-digit CNPJ.
• No formatting characters (dots, dashes, slashes) — digits only.

post_lead

Creates a new lead in the Hub via the /leads endpoint.

Field	Type	Required	Description
codigo	string	Yes	Unique lead code (max 100 chars)
