Subject: [PATCH] Add pip infrastructure and AI development tools
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Enhanced setup.py with AI-friendly documentation generation
- Added 'python setup.py aidocs' command for:
  - Automatic API documentation via pydoc
  - ctags generation for code navigation
  - Project structure documentation
  - API summary generation
- Added CLAUDE.md explaining AI-only development
- Created __main__.py for command-line interface
- Added test_claude_connection.py to verify claude-code integration
- Added py.typed for type checking support

+## 🤖 AI-Only Development Notice
+
+This repository is developed and maintained exclusively by AI assistants. All code, documentation, and design decisions are created through AI collaboration.
+
+## Project Overview
+
+MCP Browser is a generic, minimalistic Model Context Protocol (MCP) browser designed specifically for AI systems to interact with MCP servers while optimizing context usage.
+
+### Key Design Principles
+
+1. **Context Optimization First**: Every design decision prioritizes minimal token usage
+2. **Generic Interface**: No hardcoded tool knowledge - pure protocol implementation
+3. **Sparse Mode**: Initially expose only 3 tools to minimize context bloat
+4. **AI-Friendly API**: Simple `call()` and `discover()` methods for all operations
+
+## For AI Developers
+
+When working on this codebase:
+
+### Getting Started
+```bash
+# Generate AI-friendly documentation
+python setup.py aidocs
+
+# This creates:
+# - docs/STRUCTURE.md - Project structure overview
+# - docs/API_SUMMARY.md - API quick reference  
+# - .tags - ctags for code navigation
+# - HTML documentation via pydoc
+```
+
+### Core Concepts
+
+1. **Virtual Tools**: `mcp_discover`, `mcp_call`, and `onboarding` exist only in the browser layer
+2. **Tool Namespacing**: Format is `server::tool` or `mcp__namespace__tool` 
+3. **Multi-Server**: Built-in servers (screen, memory, patterns, onboarding) start automatically
+4. **Identity-Aware**: Onboarding tool accepts identity parameter for context-specific instructions
+
+### Architecture Overview
+
+```
+mcp_browser/
+├── proxy.py          # Main MCPBrowser class - entry point
+├── registry.py       # Tool storage and JSONPath discovery
+├── filter.py         # Sparse mode implementation
+├── multi_server.py   # Manages multiple MCP servers
+└── server.py         # Individual MCP server wrapper
+
+mcp_servers/
+├── base.py           # Base class for Python MCP servers
+├── screen/           # GNU screen session management
+├── memory/           # Persistent memory and tasks
+├── patterns/         # Auto-response patterns
+└── onboarding/       # Identity-aware onboarding
+```
+
+### Development Workflow
+
+1. **Always read existing code first** - Use patterns from existing implementations
+2. **Test with examples** - Run `examples/builtin_servers_demo.py` to verify changes
+3. **Maintain sparse mode** - Don't expose tools unnecessarily
+4. **Document for AI** - Comments should help future AI understand intent
+
+### Testing MCP Connections
+
+```python
+# Basic test
+from mcp_browser import MCPBrowser
+
+async with MCPBrowser() as browser:
+    # List sparse tools (only 3 visible)
+    response = await browser.call({
+        "jsonrpc": "2.0",
+        "method": "tools/list"
+    })
+    
+    # Discover all tools
+    all_tools = browser.discover("$.tools[*].name")
+```
+
+### Common Tasks
+
+**Adding a new built-in server:**
+1. Create `mcp_servers/newserver/newserver_server.py`
+2. Inherit from `BaseMCPServer`
+3. Register tools in `__init__`
+4. Add to `MultiServerManager.builtin_servers`
+
+**Modifying sparse tools:**
+1. Edit `ToolRegistry.get_sparse_tools()`
+2. Ensure tool descriptions are concise
+3. Test that only intended tools appear initially
+
+## Design Rationale
+
+- **Why sparse mode?** - Claude and other LLMs have limited context windows. Hundreds of tool descriptions can consume significant tokens.
+- **Why generic design?** - Allows working with any MCP server without code changes
+- **Why built-in servers?** - Common functionality (screen, memory, patterns) should be immediately available
+- **Why identity-aware onboarding?** - Different AI instances/projects need different context
+
+## Protocol Details
+
+MCP uses JSON-RPC 2.0 over stdin/stdout. Key methods:
+- `initialize` - Handshake and capability negotiation
+- `tools/list` - Get available tools
+- `tools/call` - Execute a tool
+- `notifications/*` - Server-initiated messages
+
+## Future AI Instructions
+
+When enhancing this codebase:
+- Maintain backward compatibility with the 2-method API
+- Keep sparse mode as default behavior
+- Document any new virtual tools clearly
+- Test with multiple MCP server implementations
+- Consider token usage in all decisions
+

+*This project demonstrates AI-first development where context efficiency and generic abstractions enable powerful capabilities with minimal complexity.*
