Skill Seeker MCP Server

Model Context Protocol (MCP) server for Skill Seeker - enables Claude Code to generate documentation skills directly.

What is This?

This MCP server allows Claude Code to use Skill Seeker's tools directly through natural language commands. Instead of running CLI commands manually, you can ask Claude Code to:

• Generate config files for any documentation site
• Estimate page counts before scraping
• Scrape documentation and build skills
• Package skills into .zip files
• List and validate configurations
• NEW: Split large documentation (10K-40K+ pages) into focused sub-skills
• NEW: Generate intelligent router/hub skills for split documentation

Quick Start

1. Install Dependencies

# From repository root
pip3 install -r mcp/requirements.txt
pip3 install requests beautifulsoup4

2. Quick Setup (Automated)

# Run the setup script
./setup_mcp.sh

# Follow the prompts - it will:
# - Install dependencies
# - Test the server
# - Generate configuration
# - Guide you through Claude Code setup

3. Manual Setup

Add to ~/.config/claude-code/mcp.json:

{
  "mcpServers": {
    "skill-seeker": {
      "command": "python3",
      "args": [
        "/path/to/Skill_Seekers/mcp/server.py"
      ],
      "cwd": "/path/to/Skill_Seekers"
    }
  }
}

Replace /path/to/Skill_Seekers with your actual repository path!

4. Restart Claude Code

Quit and reopen Claude Code (don't just close the window).

5. Test

In Claude Code, type:

List all available configs

You should see a list of preset configurations (Godot, React, Vue, etc.).

Available Tools

The MCP server exposes 9 tools:

1. generate_config

Create a new configuration file for any documentation website.

Parameters:

• name (required): Skill name (e.g., "tailwind")
• url (required): Documentation URL (e.g., "https://tailwindcss.com/docs")
• description (required): When to use this skill
• max_pages (optional): Maximum pages to scrape (default: 100)
• rate_limit (optional): Delay between requests in seconds (default: 0.5)

Example:

Generate config for Tailwind CSS at https://tailwindcss.com/docs

2. estimate_pages

Estimate how many pages will be scraped from a config (fast, no data downloaded).

Parameters:

• config_path (required): Path to config file (e.g., "configs/react.json")
• max_discovery (optional): Maximum pages to discover (default: 1000)

Example:

Estimate pages for configs/react.json

3. scrape_docs

Scrape documentation and build Claude skill.

Parameters:

• config_path (required): Path to config file
• enhance_local (optional): Open terminal for local enhancement (default: false)
• skip_scrape (optional): Use cached data (default: false)
• dry_run (optional): Preview without saving (default: false)

Example:

Scrape docs using configs/react.json

4. package_skill

Package a skill directory into a .zip file ready for Claude upload. Automatically uploads if ANTHROPIC_API_KEY is set.

Parameters:

• skill_dir (required): Path to skill directory (e.g., "output/react/")
• auto_upload (optional): Try to upload automatically if API key is available (default: true)

Example:

Package skill at output/react/

5. upload_skill

Upload a skill .zip file to Claude automatically (requires ANTHROPIC_API_KEY).

Parameters:

• skill_zip (required): Path to skill .zip file (e.g., "output/react.zip")

Example:

Upload output/react.zip using upload_skill

6. list_configs

List all available preset configurations.

Parameters: None

Example:

List all available configs

7. validate_config

Validate a config file for errors.

Parameters:

• config_path (required): Path to config file

Example:

Validate configs/godot.json

8. split_config

Split large documentation config into multiple focused skills. For 10K+ page documentation.

Parameters:

• config_path (required): Path to config JSON file (e.g., "configs/godot.json")
• strategy (optional): Split strategy - "auto", "none", "category", "router", "size" (default: "auto")
• target_pages (optional): Target pages per skill (default: 5000)
• dry_run (optional): Preview without saving files (default: false)

Example:

Split configs/godot.json using router strategy with 5000 pages per skill

Strategies:

• auto - Intelligently detects best strategy based on page count and config
• category - Split by documentation categories (creates focused sub-skills)
• router - Create router/hub skill + specialized sub-skills (RECOMMENDED for 10K+ pages)
• size - Split every N pages (for docs without clear categories)

9. generate_router

Generate router/hub skill for split documentation. Creates intelligent routing to sub-skills.

Parameters:

• config_pattern (required): Config pattern for sub-skills (e.g., "configs/godot-*.json")
• router_name (optional): Router skill name (inferred from configs if not provided)

Example:

Generate router for configs/godot-*.json

What it does:

• Analyzes all sub-skill configs
• Extracts routing keywords from categories and names
• Creates router SKILL.md with intelligent routing logic
• Users can ask questions naturally, router directs to appropriate sub-skill

Architecture

Server Structure

mcp/
├── server.py           # Main MCP server
├── requirements.txt    # MCP dependencies
└── README.md          # This file

How It Works

1. Claude Code sends MCP requests to the server
2. Server routes requests to appropriate tool functions
3. Tools call CLI scripts (doc_scraper.py, estimate_pages.py, etc.)
4. CLI scripts perform actual work (scraping, packaging, etc.)
5. Results returned to Claude Code via MCP protocol

Tool Implementation

Each tool is implemented as an async function:

async def generate_config_tool(args: dict) -> list[TextContent]:
    """Generate a config file"""
    # Create config JSON
    # Save to configs/
    # Return success message

Tools use subprocess.run() to call CLI scripts:

result = subprocess.run([
    sys.executable,
    str(CLI_DIR / "doc_scraper.py"),
    "--config", config_path
], capture_output=True, text=True)

Testing

The MCP server has comprehensive test coverage:

# Run MCP server tests (25 tests)
python3 -m pytest tests/test_mcp_server.py -v

# Expected output: 25 passed in ~0.3s

Test Coverage

• Server initialization (2 tests)
• Tool listing (2 tests)
• generate_config (3 tests)
• estimate_pages (3 tests)
• scrape_docs (4 tests)
• package_skill (3 tests)
• upload_skill (2 tests)
• list_configs (3 tests)
• validate_config (3 tests)
• split_config (3 tests)
• generate_router (3 tests)
• Tool routing (2 tests)
• Integration (1 test)

Total: 34 tests | Pass rate: 100%

Troubleshooting

MCP Server Not Loading

Symptoms:

• Tools don't appear in Claude Code
• No response to skill-seeker commands

Solutions:

1. Check configuration:

   cat ~/.config/claude-code/mcp.json
   

2. Verify server can start:

   python3 mcp/server.py
   # Should start without errors (Ctrl+C to exit)
   

3. Check dependencies:

   pip3 install -r mcp/requirements.txt
   

4. Completely restart Claude Code (quit and reopen)

5. Check Claude Code logs:

   • macOS: ~/Library/Logs/Claude Code/
   • Linux: ~/.config/claude-code/logs/

"ModuleNotFoundError: No module named 'mcp'"

pip3 install -r mcp/requirements.txt

Tools Appear But Don't Work

Solutions:

1. Verify cwd in config points to repository root

2. Check CLI tools exist:

   ls cli/doc_scraper.py
   ls cli/estimate_pages.py
   ls cli/package_skill.py
   

3. Test CLI tools directly:

   python3 cli/doc_scraper.py --help
   

Slow Operations

1. Check rate limit in configs (increase if needed)
2. Use smaller max_pages for testing
3. Use skip_scrape to avoid re-downloading data

Advanced Configuration

Using Virtual Environment

# Create venv
python3 -m venv venv
source venv/bin/activate
pip install -r mcp/requirements.txt
pip install requests beautifulsoup4
which python3  # Copy this path

Configure Claude Code to use venv Python:

{
  "mcpServers": {
    "skill-seeker": {
      "command": "/path/to/Skill_Seekers/venv/bin/python3",
      "args": ["/path/to/Skill_Seekers/mcp/server.py"],
      "cwd": "/path/to/Skill_Seekers"
    }
  }
}

Debug Mode

Enable verbose logging:

{
  "mcpServers": {
    "skill-seeker": {
      "command": "python3",
      "args": ["-u", "/path/to/Skill_Seekers/mcp/server.py"],
      "cwd": "/path/to/Skill_Seekers",
      "env": {
        "DEBUG": "1"
      }
    }
  }
}

With API Enhancement

For API-based enhancement (requires Anthropic API key):

{
  "mcpServers": {
    "skill-seeker": {
      "command": "python3",
      "args": ["/path/to/Skill_Seekers/mcp/server.py"],
      "cwd": "/path/to/Skill_Seekers",
      "env": {
        "ANTHROPIC_API_KEY": "sk-ant-your-key-here"
      }
    }
  }
}
