* feat: v2.4.0 - MCP 2025 upgrade with multi-agent support

Major MCP infrastructure upgrade to 2025 specification with HTTP + stdio
transport and automatic configuration for 5+ AI coding agents.

### 🚀 What's New

**MCP 2025 Specification (SDK v1.25.0)**
- FastMCP framework integration (68% code reduction)
- HTTP + stdio dual transport support
- Multi-agent auto-configuration
- 17 MCP tools (up from 9)
- Improved performance and reliability

**Multi-Agent Support**
- Auto-detects 5 AI coding agents (Claude Code, Cursor, Windsurf, VS Code, IntelliJ)
- Generates correct config for each agent (stdio vs HTTP)
- One-command setup via ./setup_mcp.sh
- HTTP server for concurrent multi-client support

**Architecture Improvements**
- Modular tool organization (tools/ package)
- Graceful degradation for testing
- Backward compatibility maintained

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

* fix: Add backward compatibility exports to server.py for tests

Re-export tool functions from server.py to maintain backward compatibility
with test_mcp_server.py which imports from the legacy server module.

This fixes CI test failures where tests expected functions like list_tools()
and generate_config_tool() to be importable from skill_seekers.mcp.server.

All tool functions are now re-exported for compatibility while maintaining
the deprecation warning for direct server execution.

* fix: Export run_subprocess_with_streaming and fix tool schemas for backward compatibility

- Add run_subprocess_with_streaming export from scraping_tools
- Fix tool schemas to include properties field (required by tests)
- Resolves 9 failing tests in test_mcp_server.py

* fix: Add call_tool router and fix test patches for modular architecture

- Add call_tool function to server.py for backward compatibility
- Fix test patches to use correct module paths (scraping_tools instead of server)
- Update 7 test decorators to patch the correct function locations
- Resolves remaining CI test failures

# HTTP Transport for FastMCP Server
The Skill Seeker MCP server now supports both **stdio** (default) and **HTTP** transports, giving you flexibility in how you connect Claude Desktop or other MCP clients.
## Quick Start
### Stdio Transport (Default)
```bash
# Traditional stdio transport (backward compatible)
python -m skill_seekers.mcp.server_fastmcp
```
### HTTP Transport (New!)
```bash
# HTTP transport on default port 8000
python -m skill_seekers.mcp.server_fastmcp --http
# HTTP transport on custom port
python -m skill_seekers.mcp.server_fastmcp --http --port 8080
# HTTP transport with debug logging
python -m skill_seekers.mcp.server_fastmcp --http --log-level DEBUG
```
## Why Use HTTP Transport?
### Advantages
- **Web-based clients**: Connect from browser-based MCP clients
- **Cross-origin requests**: Built-in CORS support for web applications
- **Health monitoring**: Dedicated `/health` endpoint for service monitoring
- **Multiple connections**: Support multiple simultaneous client connections
- **Remote access**: Can be accessed over network (use with caution!)
- **Debugging**: Easier to debug with browser developer tools
### When to Use Stdio
- **Claude Desktop integration**: Default and recommended for desktop clients
- **Process isolation**: Each client gets isolated server process
- **Security**: More secure for local-only access
- **Simplicity**: No network configuration needed
## Configuration
### Claude Desktop Configuration
#### Stdio (Default)
```json
{
"mcpServers": {
"skill-seeker": {
"command": "python",
"args": ["-m", "skill_seekers.mcp.server_fastmcp"]
}
}
}
```
#### HTTP (Alternative)
```json
{
"mcpServers": {
"skill-seeker": {
"url": "http://localhost:8000/sse"
}
}
}
```
## Endpoints
When running in HTTP mode, the server exposes the following endpoints:
### Health Check
**Endpoint:** `GET /health`
Returns server health status and metadata.
**Example:**
```bash
curl http://localhost:8000/health
```
**Response:**
```json
{
"status": "healthy",
"server": "skill-seeker-mcp",
"version": "2.1.1",
"transport": "http",
"endpoints": {
"health": "/health",
"sse": "/sse",
"messages": "/messages/"
}
}
```
### SSE Endpoint
**Endpoint:** `GET /sse`
Server-Sent Events endpoint for MCP communication. This is the main endpoint used by MCP clients.
**Usage:**
- Connect with MCP-compatible client
- Supports bidirectional communication via SSE
### Messages Endpoint
**Endpoint:** `POST /messages/`
Handles tool invocation and message passing from MCP clients.
## Command-Line Options
```bash
python -m skill_seekers.mcp.server_fastmcp --help
```
### Options
- `--http`: Enable HTTP transport (default: stdio)
- `--port PORT`: HTTP server port (default: 8000)
- `--host HOST`: HTTP server host (default: 127.0.0.1)
- `--log-level LEVEL`: Logging level (choices: DEBUG, INFO, WARNING, ERROR, CRITICAL)
## Examples
### Basic HTTP Server
```bash
# Start on default port 8000
python -m skill_seekers.mcp.server_fastmcp --http
```
### Custom Port
```bash
# Start on port 3000
python -m skill_seekers.mcp.server_fastmcp --http --port 3000
```
### Allow External Connections
```bash
# Listen on all interfaces (⚠️ use with caution!)
python -m skill_seekers.mcp.server_fastmcp --http --host 0.0.0.0 --port 8000
```
### Debug Mode
```bash
# Enable debug logging
python -m skill_seekers.mcp.server_fastmcp --http --log-level DEBUG
```
## Security Considerations
### Local Development
- Default binding to `127.0.0.1` ensures localhost-only access
- Safe for local development and testing
### Remote Access
- **⚠️ Warning**: Binding to `0.0.0.0` allows network access
- Implement authentication/authorization for production
- Consider using reverse proxy (nginx, Apache) with SSL/TLS
- Use firewall rules to restrict access
- Consider VPN for remote team access
### CORS
- HTTP transport includes CORS middleware
- Configured to allow all origins in development
- Customize CORS settings for production in `server_fastmcp.py`
## Testing
### Automated Tests
```bash
# Run HTTP transport tests
pytest tests/test_server_fastmcp_http.py -v
```
### Manual Testing
```bash
# Run manual test script
python examples/test_http_server.py
```
### Health Check Test
```bash
# Start server
python -m skill_seekers.mcp.server_fastmcp --http &
# Test health endpoint
curl http://localhost:8000/health
# Stop server
killall python
```
## Troubleshooting
### Port Already in Use
```
Error: [Errno 48] Address already in use
```
**Solution:** Use a different port
```bash
python -m skill_seekers.mcp.server_fastmcp --http --port 8001
```
### Cannot Connect from Browser
- Ensure server is running: `curl http://localhost:8000/health`
- Check firewall settings
- Verify port is not blocked
- For remote access, ensure using correct IP (not 127.0.0.1)
### uvicorn Not Installed
```
Error: uvicorn package not installed
```
**Solution:** Install uvicorn
```bash
pip install uvicorn
```
## Architecture
### Transport Flow
#### Stdio Mode
```
Claude Desktop → stdin/stdout → MCP Server → Tools
```
#### HTTP Mode
```
Claude Desktop/Browser → HTTP/SSE → MCP Server → Tools
↓
Health Check
```
### Components
- **FastMCP**: Underlying MCP server framework
- **Starlette**: ASGI web framework for HTTP
- **uvicorn**: ASGI server for production
- **SSE**: Server-Sent Events for real-time communication
## Performance
### Benchmarks (Local Testing)
- **Startup time**: ~200ms (HTTP), ~100ms (stdio)
- **Health check latency**: ~5-10ms
- **Tool invocation overhead**: ~20-50ms (HTTP), ~10-20ms (stdio)
### Recommendations
- **Single user**: Use stdio (simpler, faster)
- **Multiple users**: Use HTTP (connection pooling)
- **Production**: Use HTTP with reverse proxy
- **Development**: Use stdio for simplicity
## Migration Guide
### From Stdio to HTTP
1. **Update server startup:**
```bash
# Before
python -m skill_seekers.mcp.server_fastmcp
# After
python -m skill_seekers.mcp.server_fastmcp --http
```
2. **Update Claude Desktop config:**
```json
{
"mcpServers": {
"skill-seeker": {
"url": "http://localhost:8000/sse"
}
}
}
```
3. **Restart Claude Desktop**
### Backward Compatibility
- Stdio remains the default transport
- No breaking changes to existing configurations
- HTTP is opt-in via `--http` flag
