This is an early dev version — not plug-and-play yet. You’ll need to know your way around Docker networks and storage mapping.

🧩 AnythingLLM MCP HTTP Bridge

Lightweight HTTP bridge for AnythingLLM to connect multiple local MCP servers securely via Docker.
A clean, modular, and safe way to run multiple MCP servers without Docker-in-Docker or direct process spawning.

---

🚀 Overview

This bridge allows AnythingLLM to communicate with multiple MCP servers inside isolated Docker containers.
It provides a single, secure HTTP entry point while keeping each MCP fully sandboxed.

✅ Key Features

• 🔒 Safe & clean: No host or Docker-in-Docker access.
• 🧱 Modular: Each MCP runs in its own container with a small FastAPI server.
• 🌐 Bridge-controlled: AnythingLLM only talks to the bridge (mini-bridge), never to the MCPs directly.
• ⚙️ Dynamic registry: MCP servers are auto-loaded from mcp_registry.json.
• ♻️ Auto reload: The bridge reloads configuration changes live without restarting containers.
• 🕒 Example MCPs: Includes a Dummy-MCP for testing and a working MCP-Time module returning system time.

🧠 Architecture

───────────────────────────────
Docker Network: test-net
───────────────────────────────
│
├─ anythingllm  (Port 3001)
│     ↳ Main app – talks only to mini-bridge
│
├─ mini-bridge  (Port 4100)
│     ↳ Forwards JSON-RPC requests to registered MCPs
│     ↳ Reloads mcp_registry.json dynamically
│
├─ dummy-mcp    (Port 4200)
│     ↳ JSON-RPC test MCP returning handshake info
│
└─ mcp-time     (Port 4210)
      ↳ Returns current UTC time

⚙️ Quick Setup

git clone https://github.com/yourname/anythingllm-mcp-http-bridge.git
cd anythingllm-mcp-http-bridge
docker compose up --build

Bridge log output:

[Bridge] Registry reloaded: ['dummy', 'time']
[Bridge] Default route → dummy (200)

Then open AnythingLLM → MCP Settings →
Add new server: http://mini-bridge:4100

📜 MCP Registry Example

mini_bridge/config/mcp_registry.json

{
  "autoReload": true,
  "servers": [
    {
      "id": "dummy",
      "name": "Dummy MCP",
      "url": "http://dummy-mcp:4200",
      "type": "streamable",
      "enabled": true
    },
    {
      "id": "time",
      "name": "Time MCP",
      "url": "http://mcp-time:4210",
      "type": "streamable",
      "enabled": true
    }
  ]
}

🧩 Available MCP Modules

MCP	Description	Example call
Dummy-MCP	Minimal test server, responds to initialize, ping, etc.	POST /dummy
MCP-Time	Returns current UTC time	tools/call → get_time

Test manually:

curl -X POST http://localhost:4100/time      -H "Content-Type: application/json"      -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_time"}}'

Response:

{"jsonrpc":"2.0","id":1,"result":{"message":"The current time is 18:42:10 UTC"}}

🔒 Security

Each MCP server runs in its own container on a private Docker network.
The bridge is the only exposed interface and accepts JSON-RPC over HTTP — nothing else.

• No direct container access from AnythingLLM
• No Docker-in-Docker
• No shell or file system commands
• Safe, stateless JSON-based communication only

💬 Development Note

I’ll keep improving this project as my own independent solution.
If the AnythingLLM team finds the idea useful, feel free to build on it or integrate parts of it.

As of now, tool output is still returned in a raw format instead of a fully formatted chat reply — once that’s refined, the public release will follow.
