Installation

Via MCP Registry (Recommended)

The server is published in the official MCP Registry as io.github.zeiq-co/thoth-mcp.

Browse and install via the registry web interface, or configure directly in your MCP client (see MCP Client Configuration below).

Via Smithery (Zero-Setup Deployment)

The easiest way to get started is through Smithery, which provides:

• One-click installation - No local dependencies or configuration needed

• Automatic updates - Always get the latest version

• Secure hosting - Your API keys are safely managed

• Interactive playground - Test tools before using them

Install from Smithery:

1. Visit the Thoth MCP Server on Smithery

2. Click "Install"

3. Enter your Thoth API key when prompted

4. Start using immediately in Claude Desktop or other MCP clients

Global Installation (via npx)

npx @usethoth/mcp-server --api-key YOUR_API_KEY

Local Development

git clone https://github.com/perminder-klair/thoth-mcp.git
cd thoth-mcp
pnpm install
pnpm build

Usage

Prerequisites

You'll need a Thoth API key. Generate one at:

• Production: https://app.usethoth.com/settings/api-keys

• Development: http://localhost:3000/settings/api-keys

Running the Server

Stdio Mode (Local)

This is the default mode for use with MCP clients like Claude Desktop:

npx @usethoth/mcp-server --api-key YOUR_API_KEY

Or debug with MCP Inspector:

npx @modelcontextprotocol/inspector npx @usethoth/mcp-server --api-key YOUR_API_KEY

With custom base URL:

npx @usethoth/mcp-server \
  --api-key YOUR_API_KEY \
  --base-url https://app.usethoth.com

Remote HTTP Server Mode

Run the server in HTTP mode for cloud deployments (like Smithery) or to expose the server over HTTP:

npx @usethoth/mcp-server --remote --api-key YOUR_API_KEY

The server will start an HTTP server on port 8081 (configurable via PORT environment variable) with:

• /mcp - Main MCP endpoint (POST)

• /health - Health check endpoint (GET)

With custom configuration:

PORT=3000 npx @usethoth/mcp-server \
  --remote \
  --api-key YOUR_API_KEY \
  --base-url https://app.usethoth.com

Note: In HTTP mode, the server implements MCP Streamable HTTP transport with proper CORS configuration for browser-based clients.

Environment Variables

Instead of command-line flags, you can use environment variables:

For stdio mode:

export THOTH_API_KEY=your_api_key
export THOTH_BASE_URL=http://localhost:3000
npx @usethoth/mcp-server

For HTTP mode:

export THOTH_API_KEY=your_api_key
export THOTH_BASE_URL=https://www.usethoth.com
export PORT=8081
npx @usethoth/mcp-server --remote

Available environment variables:

• THOTH_API_KEY - Your Thoth API key (stdio mode only; HTTP mode uses query params)

• THOTH_BASE_URL - Base URL for Thoth API (default: https://www.usethoth.com)

• PORT - HTTP server port (HTTP mode only, default: 8081)

MCP Client Configuration

Claude Desktop

Add to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "thoth": {
      "command": "npx",
      "args": [
        "@usethoth/mcp-server",
        "--api-key",
        "YOUR_API_KEY",
        "--base-url",
        "http://localhost:3000"
      ]
    }
  }
}

Other MCP Clients

For other MCP clients that support stdio transport, use a similar configuration with appropriate command and args.

The server provides detailed error messages for common issues:

• Invalid API Key: Check your API key is correct and active

• Rate Limit Exceeded: Wait before making additional requests

• Post Not Found: Verify the post ID is correct

• Invalid Parameters: Check parameter types and formats

• Network Errors: Verify the base URL and network connection

Examples

Creating a Multi-Platform Post

{
  "content": "Excited to share our latest feature! \ud83d\ude80 AI-powered content optimization for all your social platforms.",
  "platforms": ["twitter", "linkedin", "instagram"],
  "length": "medium",
  "createImage": true,
  "createHashtags": true
}

Scheduling a Post

{
  "content": "Join us for our product launch next week!",
  "platforms": ["twitter", "linkedin"],
  "scheduleTime": "2025-10-20T14:00:00Z",
  "createImage": true
}

Retrieving Post Data

// Using the get-post tool
{
  "postId": "123e4567-e89b-12d3-a456-426614174000"
}

Accessing Resources

// Read post resource
{
  "uri": "post://123e4567-e89b-12d3-a456-426614174000"
}

// Read platform-specific preview
{

}

Testing HTTP Mode Locally

Start the server in HTTP mode:

npx @usethoth/mcp-server --remote --api-key YOUR_API_KEY

Test the health endpoint:

curl http://localhost:8081/health

Test the MCP endpoint with MCP Inspector:

npx @modelcontextprotocol/inspector http://localhost:8081/mcp?apiKey=YOUR_API_KEY

Or use with a Streamable HTTP MCP client that supports query-based configuration.

Troubleshooting

Server won't start

• Check that you have Node.js 18+ installed

• Verify your API key is valid

• Ensure the base URL is correct and accessible

Tool calls fail

• Verify your API key has the required permissions

• Check rate limits haven't been exceeded

• Ensure post IDs are valid UUIDs

• Verify platform names are spelled correctly

HTTP mode not accessible

• Check the port isn't already in use: lsof -i :8081 (or your configured PORT)

• Verify firewall settings allow the connection

• Ensure the server process is running with the --remote flag

• Check the server logs for any startup errors

• Verify the /health endpoint responds: curl http://localhost:8081/health

• For Smithery deployments, check the deployment logs in the Smithery dashboard

Smithery deployment fails

• Ensure your GitHub repository is public or connected to Smithery

• Verify smithery.yaml and Dockerfile are in the repository root

• Check the build logs in Smithery dashboard for specific errors

• Ensure all dependencies are declared in package.json

• Try building the Docker image locally: docker build -t thoth-mcp .

Contributing

Contributions are welcome! Please follow these steps:

1. Fork the repository

2. Create a feature branch (git checkout -b feature/amazing-feature)

3. Commit your changes (git commit -m 'Add amazing feature')

4. Push to the branch (git push origin feature/amazing-feature)

5. Open a Pull Request

Please ensure your code:

• Follows the existing TypeScript style

• Includes appropriate Zod schemas for validation

• Updates documentation as needed

• Passes type checking (pnpm typecheck)

• Uses console.error() for logging (not console.log() - it breaks stdio mode)

For Maintainers

See PUBLISHING.md for detailed instructions on building and publishing updates.
