A ConnectWise PSA MCP server, so Claude can work with your ConnectWise data

Status: no official server yet

Authentication

The REST API lives at https://{your-site}/v4_6_release/apis/3.0. For cloud tenants in North America the host is api-na.myconnectwise.net.

Authentication uses API member keys. Each request sends a Basic header built from base64(companyId+publicKey:privateKey), plus a clientId header.

Honest limits

• You need a Client ID from developer.connectwise.com before any request works. It is registered on your side, or by us with your access.
• The tools can only see and change what the API member is allowed to. Use a dedicated API member with the narrowest access that covers the agreed tools.
• Write tools (create, update, notes, time) change live PSA data. We can ship a read-only build first if you prefer.

How you’d connect it

The server runs two ways: locally over stdio, started with npx, or remotely over Streamable HTTP at a URL on your own host. The commands below use placeholders; your README has the real package name, URL and variables. NOLU does not run a shared hosted ConnectWise server.

Claude Code

# remote (Streamable HTTP)
claude mcp add --transport http connectwise-psa https://<your-host>/mcp

# local (stdio)
claude mcp add connectwise-psa -e CW_SITE=<value> -e CW_COMPANY_ID=<value> -e CW_PUBLIC_KEY=<value> -e CW_PRIVATE_KEY=<value> -e CW_CLIENT_ID=<value> -- npx -y <your-server-package>

Claude Desktop

For a remote server, add the URL https://<your-host>/mcp as a custom connector. For a local server, add it to claude_desktop_config.json:

{
  "mcpServers": {
    "connectwise-psa": {
      "command": "npx",
      "args": ["-y", "<your-server-package>"],
      "env": {
        "CW_SITE": "<value>",
        "CW_COMPANY_ID": "<value>",
        "CW_PUBLIC_KEY": "<value>",
        "CW_PRIVATE_KEY": "<value>",
        "CW_CLIENT_ID": "<value>"
      }
    }
  }
}

Cursor

In .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "connectwise-psa": { "url": "https://<your-host>/mcp" }
  }
}

Variable names above are examples. Keep credentials in local config or your host’s secret store, never in the repository.

Who it is for

• ConnectWise customers (MSPs) who want Claude to work with their own ConnectWise account, using their own credentials.
• ConnectWise itself, if it wants an MCP server built around its API for its customers. That usually means the Standard tier, with OAuth so each user signs in with their own account.
