A decentralized, multi-agent peer-to-peer (P2P) Model Context Protocol (MCP) router built strictly in **Python 3.10+**. It bridges physically distributed, independent MCP servers into an encrypted, self-healing swarm mesh, complete with an interactive **Streamlit Web Application Control Center**.

## 🌟 Key Architecture & Capabilities

* **👑 Gateway Node Lifecycle (`FR-01`)**: Bridges upstream MCP clients (Claude Desktop, Cursor, Autonomous Agents) over standard Stdio and SSE transports.
* **🌐 P2P Transport & Dynamic Discovery (`FR-02`)**: Decentralized node discovery over asynchronous UDP gossip protocol and encrypted mutual TLS 1.3 socket streams.
* **📋 Dynamic Capability Registry (`FR-03`)**: Aggregates tools, resources, and prompt templates into a unified catalog exposed via `mesh://capabilities/registry`.
* **⚡ Distributed Task Delegation (`FR-04`)**: Routes execution payloads via `mesh_delegate_task` to specific or auto-selected peers with progress streaming.
* **🤝 Swarm Consensus Orchestration (`FR-05`)**: Coordinates multi-agent deliberation routines (`swarm_consensus_review`) with customizable quorum thresholds and variance synthesis.
* **🔐 Zero-Trust Security (`NFR-02`)**: Cryptographic Ed25519 identity, ephemeral TLS X.509 certs, and EdDSA-signed capability JWT tokens with replay-attack nonce caching.
* **🛡️ Fault Tolerance & Isolation (`NFR-03`)**: Heartbeat decay failure detector isolating `SUSPECT` nodes at 10s and evicting `DEAD` nodes at 15s with automatic split-brain recovery.
* **⚡ High Performance (`NFR-04`)**: Verified intra-mesh routing overhead strictly `< 50ms` (measured ~3.5ms on localhost).

## 🖥️ Streamlit Control Center (`app.py`)

The repository includes a modern, operator-grade Streamlit web application with 5 interactive views:
1. **Mesh Topology Matrix**: Live Graphviz network graph and node status table with color-coded health states (`ALIVE`, `SUSPECT`, `DEAD`).
2. **Capability Registry Browser**: Searchable tools inventory, schema inspector, and live `mesh://capabilities/registry` JSON manifest viewer.
3. **Task Delegation Workbench**: Real-time form to issue delegated calls, generate signed EdDSA JWT tokens, and monitor execution latencies.
4. **Swarm Consensus Chamber**: Interactive multi-agent consensus prompts, quorum adjustments, and score synthesis.
5. **Security & Framing Telemetry**: Cryptographic key inspector, wire frame codec diagrams, and replay nonce cache monitor.

## 🚀 Quick Start

### 1. Installation
```bash
git clone https://github.com/shinevijayan03/mcp-p2p-swarm-mesh.git
cd mcp-p2p-swarm-mesh

# Create virtualenv
python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

# Install package
pip install -e ".[dev]"
```

### 2. Launch the Streamlit Control Center
```bash
streamlit run app.py
```
Open your browser at `http://127.0.0.1:8501`.

### 3. Run Gateway Server
```bash
# Stdio transport mode (e.g. for Claude Desktop)
python -m mcp_mesh.gateway.server --mcp-mode stdio

# SSE transport mode
python -m mcp_mesh.gateway.server --mcp-mode sse --mcp-port 8000
```

## 🧪 Testing

The repository maintains an exhaustive test suite covering unit tests, integration tests, chaos network simulations, and security penetration vectors:

```bash
# Run all tests
pytest -v

# Run with test coverage report
pytest --cov=mcp_mesh --cov-report=term-missing tests/
```

**Result**: 28 passed, 0 failed (100% pass rate).
