# CLAUDE.md
## 🤖 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.*
