### Description (declared)

# SymPy Sandbox MCP

English | [中文版](README.zh.md)

A production-focused MCP service that lets agents/LLMs run SymPy safely and efficiently.
It combines AST policy checks, runtime resource limits, and prewarmed workers to deliver low-noise, parse-friendly results.

## Features

- Single tool: `sympy` (input only requires `code`)
- Prewarmed worker pool to avoid repeated `import sympy`
- Two-layer safety: AST guard + runtime resource limits
- Compact structured JSON output for low token overhead
- Standardized error codes for reliable auto-retry workflows

## Typical Use Cases

- Symbolic algebra, differentiation, integration, equation solving
- MCP tool integration for Codex / Cursor / Claude Desktop / custom MCP clients
- Agent workflows that need controllable failures and clean error signals

## Recommended Integration (MCP client via stdio)

Call example:

```bash
fastmcp call \
  --command 'python -m sym_mcp.server' \
  --target sympy \
  --input-json '{"code":"import sympy as sp\\nx=sp.Symbol(\"x\")\\nprint(sp.factor(x**2-1))"}'
```

Client config (`python -m`, recommended):

```json
{
  "mcpServers": {
    "sympy-sandbox": {
      "command": "python",
      "args": ["-m", "sym_mcp.server"]
    }
  }
}
```

Client config (installed as `sym-mcp`):

```json
{
  "mcpServers": {
    "sympy-sandbox": {
      "command": "sym-mcp",
      "args": []
    }
  }
}
```

Client config (`uvx`):

```json
{
  "mcpServers": {
    "sympy-sandbox": {
      "command": "uvx",
      "args": ["sym-mcp"]
    }
  }
}
```

## Quick Start

### 1) Requirements

- Python 3.11+
- Linux / macOS (Linux recommended for production)

### 2) Install (Tsinghua mirror first)

```bash

```

### 3) Run server (stdio)

```bash
python -m sym_mcp.server
```

### 4) Verify tool

```bash
fastmcp list --command 'python -m sym_mcp.server'
```
