- Generates comprehensive JSON documentation of MCP API
- Includes all servers, tools, schemas, and capabilities
- AI-optimized format with discovery patterns
- Runtime server status information
- Perfect for adding to project knowledge bases
**API Documentation Features**:
- Complete server inventory with tool counts
- Capability inference from tool names/descriptions
- Discovery pattern examples for common queries
- Sparse mode information for context optimization
- Tool grouping by server with metadata
This enables powerful regex-based tool discovery and provides
comprehensive API documentation for AI consumption.

The server was hanging on initialize requests because:
1. It was calling browser.initialize() at startup which tried to connect to upstream servers
2. It was using blocking stdin.read(4096) instead of line-based reading
Fixed by:
- Removing premature initialization in server mode (let it happen lazily)
- Switching to readline() for proper line-based JSON-RPC handling
- Adding proper error responses for malformed JSON
This resolves the 60-second timeout error when Claude Desktop tries to connect.

Major refactoring to fix high CPU usage and improve architecture:
## Fixed Issues
- MCP servers were stuck in infinite loops when stdin closed
- Fixed by checking for EOF (empty string) from stdin.read()
- Fixed indentation error in base.py causing syntax errors
## New Architecture
- Split into separate client and daemon binaries:
- `mcp-browser`: Smart client that can use daemon or run standalone
- `mcp-browser-daemon`: Persistent daemon process
- `mcp-browser-legacy`: Old monolithic version (deprecated)
## Client Features
- Auto-detects and uses daemon if available
- Can auto-start daemon if needed
- Falls back to standalone mode
- Supports `--use-daemon` with modes: auto, always, never
- Works as MCP server (stdin/stdout) or CLI tool
## Daemon Features
- Runs as background process with socket server
- Supports multiple concurrent clients
- Can run in foreground with `--foreground`
- Includes systemd service files for production
- Proper signal handling and cleanup
## Usage Examples
```bash
# CLI usage (auto-uses daemon if available)
mcp-browser tools-list
mcp-browser tools-call builtin:patterns::list_patterns '{}'
# Force standalone mode
mcp-browser --use-daemon never tools-list
# Run daemon manually
mcp-browser-daemon --foreground --log-level DEBUG
# Use as MCP server
echo '{"method":"tools/list"}' | mcp-browser --mode server
```

- Added comprehensive logging system with configurable levels
- TRACE: Shows raw JSON-RPC I/O with server names
- DEBUG: Detailed operational logging
- INFO/WARNING/ERROR: Standard logging levels
- New command line options:
- --log-level: Set logging level (TRACE/DEBUG/INFO/WARNING/ERROR)
- --log-file: Log to file instead of stderr
- Improved error handling and timeouts:
- Initial server discovery timeout reduced to 3 seconds
- Servers marked as offline for 30 minutes after failure
- Better error messages with server context
- All debug output now goes to stderr, keeping stdout clean for JSON
Example usage:
mcp-browser --log-level TRACE tools-list # See raw I/O
mcp-browser --debug --log-file debug.log # Debug to file
