## Why This Exists

MCP (Model Context Protocol) is incredible, but connecting AI agents to filesystems hits real-world walls:

| Problem | fs-mcp Solution |
|---------|-----------------|
| **Container Gap** — Stdio doesn't work across Docker boundaries | HTTP server by default — connect from anywhere |
| **Token Waste** — Agents dump entire files to find one function | Smart `grep -> read` pattern with section hints |
| **Schema Hell** — Gemini silently corrupts nested object schemas | Auto-transforms schemas at runtime — just works |
| **Blind Overwrites** — One hallucination wipes your `main.py` | Human-in-the-loop review with VS Code diff |
| **Verbose Output** — build/test/git output wastes context window | RTK compresses tool output 30-70% automatically |

**fs-mcp** is a Python-based server built on `fastmcp` that treats **efficiency**, **safety**, and **universal compatibility** as first-class citizens.

## Quick Start

### Run Instantly

```bash
# One command — launches Web UI (8123) + HTTP Server (8124)
uvx fs-mcp .
```

### Selective Launch

```bash
# HTTP only (headless / Docker / CI)
fs-mcp --no-ui .

# UI only (local testing)
fs-mcp --no-http .
```

### Docker

```bash
# In your Dockerfile or entrypoint
uvx fs-mcp --no-ui --http-host 0.0.0.0 --http-port 8124 /app
```
