mcp-forge is a testing framework for [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) servers. It works with **any** MCP server — Python, TypeScript, Go, Rust — and requires **zero LLM calls**. Tests are deterministic, fast, and free to run in CI/CD.

## Why?

Most MCP server testing today looks like this: spin up Claude Desktop, type a prompt, squint at the output, and hope it called the right tool. That's vibe-testing.

mcp-forge gives you real tests:

```python
import pytest
from mcp_forge import MCPTestClient

@pytest.fixture
async def client():
    async with MCPTestClient.from_command("python my_server.py") as c:
        yield c

async def test_tool_exists(client):
    tools = await client.list_tools()
    assert "search_files" in [t.name for t in tools]

async def test_search_works(client):
    result = await client.call_tool("search_files", {"query": "README"})
    assert result.is_success
    assert "README.md" in result.text

async def test_search_snapshot(client, forge_snapshot):
    result = await client.call_tool("search_files", {"query": "README"})
    forge_snapshot.assert_match(result)
```

## Installation

```bash
pip install forge-mcp
```

With FastMCP in-memory testing support:
```bash
pip install "forge-mcp[fastmcp]"
```

## Quick Start

### 1. Write tests directly

```python
from mcp_forge import MCPTestClient

async def test_my_server():
    async with MCPTestClient.from_command("python my_server.py") as clien…
