# UseKeen MCP Server

MCP Server for the UseKeen API, enabling Claude and other AI assistants to search documentation.

## Tools

### `usekeen_package_doc_search`
   - Search documentation of packages and services to find implementation details, examples, and specifications
   - Required inputs:
     - `package_name` (string): Name of the package or service to search documentation for (e.g. 'react', 'aws-s3', 'docker')
   - Optional inputs:
     - `query` (string): Search term to find specific information within the package/service documentation (e.g. 'file upload example', 'authentication methods')
   - Returns: Documentation search results with relevant matches, URLs, and snippets

## Prerequisites

1. **UseKeen API Key**: Get a UseKeen API key from the UseKeen service
2. **Node.js** (for NPX installation) or **Docker** (for Docker installation)
3. **Claude Desktop** or **VS Code with MCP extension**

## Installation

### Option 1: NPX (Recommended)

The easiest way to use this MCP server is via NPX:

```bash
npx usekeen-mcp
```

### Option 2: Docker

You can also run the server using Docker:

```bash
docker run -e USEKEEN_API_KEY=your_api_key_here mcp/usekeen
```

### Option 3: Local Development

For local development or manual installation:

```bash
# Clone the repository
git clone <repository-url>
cd usekeen-mcp

# Copy environment file and add your API key
cp .env.example .env
# Edit .env and add your USEKEEN_API_KEY

# Install dependencies
npm install

# Build and run
npm run build
npm start
```

## Configuration

### Usage with Claude Desktop

Add the following to your `claude_desktop_config.json`:

#### NPX

```json
{
  "mcpServers": {
    "usekeen": {
      "command": "npx",
      "args": [
        "-y",
        "usekeen-mcp"
      ],
      "env": {
        "USEKEEN_API_KEY": "your_api_key_here"
      }
    }
  }
}
```

#### Docker

```json
{
  "mcpServers": {
    "usekeen": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "USEKEEN_API_KEY",
        "mcp/usekeen"
      ],
      "env": {
        "USEKEEN_API_KEY": "your_api_key_here"
      }
    }
  }
}
```

### Usage with VS Code

For manual installation, add the following JSON block to your User Settings (JSON) file in VS Code. You can do this by pressing `Ctrl + Shift + P` and typing `Preferences: Open Settings (JSON)`.

Optionally, you can add it to a file called `.vscode/mcp.json` in your workspace. This will allow you to share the configuration with others.

> Note that the `mcp` key is not needed in the `.vscode/mcp.json` file.

#### NPX

```json
{
  "mcp": {
    "inputs": [
      {
        "type": "promptString",
        "id": "usekeen_api_key",
        "description": "UseKeen API Key",
        "password": true
      }
    ],
    "servers": {
      "usekeen": {
        "command": "npx",
        "args": ["-y", "usekeen-mcp"],
        "env": {
          "USEKEEN_API_KEY": "${input:usekeen_api_key}"
        }
      }
    }
  }
}
```

#### Docker

```json
{
  "mcp": {
    "inputs": [
      {
        "type": "promptString",
        "id": "usekeen_api_key",
        "description": "UseKeen API Key",
        "password": true
      }
    ],
    "servers": {
      "usekeen": {
        "command": "docker",
        "args": ["run", "-i", "--rm", "mcp/usekeen"],
        "env": {
          "USEKEEN_API_KEY": "${input:usekeen_api_key}"
        }
      }
    }
  }
}
```

### Manual Setup

#### Using the Helper Scripts

We provide two helper scripts to make it easier to run the server:

1. **Local Execution**:
   ```bash
   # Make the script executable (first time only)
   chmod +x run-local.sh
   
   # Run the server locally
   ./run-local.sh
   ```

2. **Docker Execution**:
   ```bash
   # Make the script executable (first time only)
   chmod +x run-docker.sh
   
   # Run the server in Docker
   ./run-docker.sh
   ```

Both scripts will check for a `.env` file containing your `USEKEEN_API_KEY`. You can create this file based on the provided `.env.example`.

#### Running with npm

Set the `USEKEEN_API_KEY` environment variable and run the server:

```bash
# Install dependencies
npm install

# Build the TypeScript code
npm run build

# Run the server
USEKEEN_API_KEY=your_api_key npm start
```

#### Running with Docker

Build and run the Docker container with the API key:

```bash
# Build the Docker image
docker build -t mcp/usekeen .

# Run the container
docker run -e USEKEEN_API_KEY=your_api_key mcp/usekeen
```

### Environment Variables

- `USEKEEN_API_KEY`: Required. Your UseKeen API key for authentication.

### Troubleshooting

If you encounter errors, verify that:
1. Your UseKeen API key is valid and correctly set in your configuration
2. You have an active internet connection to reach the UseKeen API
3. The UseKeen service is currently available

#### MCP result shape errors

- The server always returns MCP-compliant tool results as `result.content` (array of content blocks). Some clients display a generic error if a custom object is returned instead of `content`. This server normalizes API responses and also sets `isError: true` for failures so clients render them correctly. If integrating new tools, ensure they return `{ content: [{ type: "text", text: "..." }] }` and never wrap results under custom keys like `{ result: { results: [...] } }`.

## Build

Docker build:

```bash
docker build -t mcp/usekeen .
```
