Quick Start (Hosted)

Connect instantly to the hosted Counsel MCP server - no installation required:

http://counsel-mcp.getmason.dev/mcp

For MCP clients that support HTTP transport, simply add:

{
  "mcpServers": {
    "counsel": {
      "url": "http://counsel-mcp.getmason.dev/mcp",
      "transport": "http"
    }
  }
}

OAuth authentication is handled automatically by your MCP client.

---

Installation (Self-Hosted)

Run your own instance of the Counsel MCP server locally.

Prerequisites

1. Node.js 18+ installed on your system
2. A Counsel account at counsel.getmason.dev

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "counsel": {
      "command": "npx",
      "args": ["-y", "counsel-mcp-server", "start"]
    }
  }
}

{
  "mcpServers": {
    "counsel": {
      "command": "npx",
      "args": ["-y", "counsel-mcp-server", "start"]
    }
  }
}

Claude Code (CLI)

claude mcp add counsel -- npx -y counsel-mcp-server start

Or manually add to your MCP settings:

{
  "mcpServers": {
    "counsel": {
      "command": "npx",
      "args": ["-y", "counsel-mcp-server", "start"]
    }
  }
}

Cursor

Add to your Cursor MCP configuration (.cursor/mcp.json in your project or global settings):

{
  "mcpServers": {
    "counsel": {
      "command": "npx",
      "args": ["-y", "counsel-mcp-server", "start"]
    }
  }
}

Windsurf

Add to your Windsurf MCP configuration:

{
  "mcpServers": {
    "counsel": {
      "command": "npx",
      "args": ["-y", "counsel-mcp-server", "start"]
    }
  }
}

VS Code with Copilot

Add to your VS Code settings (settings.json):

{
  "mcp.servers": {
    "counsel": {
      "command": "npx",
      "args": ["-y", "counsel-mcp-server", "start"]
    }
  }
}

Other MCP Clients

The server supports two transport modes. Choose based on your client's capabilities:

STDIO Mode (Default)

Most MCP clients use STDIO transport. Configure with:

{
  "mcpServers": {
    "counsel": {
      "command": "npx",
      "args": ["-y", "counsel-mcp-server", "start"],
      "env": {
        "COUNSEL_API_KEY": "your_api_key_here"
      }
    }
  }
}

HTTP Mode with OAuth

For clients that support HTTP transport with OAuth 2.0, run the server separately:

# Start the HTTP server
npx -y counsel-mcp-server http --port 3000

This starts an HTTP server with:

• MCP endpoint: http://localhost:3000/mcp
• OAuth discovery: http://localhost:3000/.well-known/oauth-authorization-server

Then configure your client to connect:

{
  "mcpServers": {
    "counsel": {
      "url": "http://localhost:3000/mcp",
      "transport": "http"
    }
  }
}

HTTP mode uses OAuth 2.0 with automatic token management - no API key required.

Transport Comparison

Feature	STDIO Mode	HTTP Mode
Command	npx -y counsel-mcp-server start	npx -y counsel-mcp-server http
Auth	API key via env var	OAuth 2.0 (automatic)
Setup	Single config	Run server + configure client
Best for	Claude Desktop, Cursor, VS Code	Web clients, shared servers

---

Authentication

The server supports two authentication modes:

STDIO Mode (Default)

Set the COUNSEL_API_KEY environment variable with your API key from counsel.getmason.dev:

export COUNSEL_API_KEY=your_api_key_here

Or add it to your MCP client configuration:

{
  "mcpServers": {
    "counsel": {
      "command": "npx",
      "args": ["-y", "counsel-mcp-server", "start"],
      "env": {
        "COUNSEL_API_KEY": "your_api_key_here"
      }
    }
  }
}

HTTP Mode (OAuth 2.0)

When running in HTTP mode (npx -y counsel-mcp-server http), authentication is handled automatically through OAuth 2.0:

1. When you first use a Counsel tool, your MCP client will prompt for authentication
2. You'll be redirected to sign in with your Counsel account
3. After authorization, tokens are managed automatically

No manual API key required in HTTP mode - your MCP client handles the entire OAuth flow.

OAuth Endpoints (HTTP Mode)

The server exposes standard OAuth 2.0 endpoints:

Endpoint	Description
/.well-known/oauth-authorization-server	OAuth metadata discovery
/authorize	Authorization endpoint
/token	Token exchange endpoint
/register	Dynamic client registration

Troubleshooting

"Tool not found" Error

Ensure the MCP server is properly configured in your client. Restart your client after adding the configuration.

Authentication Issues

1. Check that you have a valid Counsel account
2. Try removing and re-adding the MCP server configuration
3. Clear your client's MCP cache if available

Connection Refused

If running in HTTP mode, ensure:

• The server is running (npx counsel-mcp-server start)
• The port isn't blocked by a firewall
• No other process is using the same port

Server Not Starting

# Check Node.js version (requires 18+)
node --version

# Try running directly to see errors
npx counsel-mcp-server start

Debug Mode

For verbose logging, check your MCP client's logs or run the server directly in a terminal to see output.
