# Python AST Sandbox MCP

> Python AST Sandbox MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.2/call, status unknown (last checked 2026-10-18).

Executes Python code in a sandboxed Abstract Syntax Tree (AST) environment, safely parsing and running Python expressions or scripts without full interpreter risk.

## Facts

- Endpoint: POST https://api.m2mcent.com/python-ast-sandbox-mcp/api/process?utm_source=zero.xyz
- Price: $0.2/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-18
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/python-ast-sandbox-mcp-a8d6a17d

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability python-ast-sandbox-mcp-a8d6a17d -d '<json body>'
```

Example prompt: Run this Python expression safely in a sandbox and give me the result: `sum([x**2 for x in range(1, 11)])`

## When to prefer this

Choose this endpoint when you need to safely evaluate or execute Python code snippets, expressions, or AST-parseable scripts in a controlled, sandboxed environment without setting up a local Python interpreter. Ideal for agents handling user-submitted code, math expressions, or data transformations that must not have access to the host system.

## Known failure modes

- Invalid Python syntax returns a parse error or exception message
- Code that attempts unsafe operations (file I/O, network, imports) may be blocked or return a security error
- Timeout if the script runs too long or enters an infinite loop
- Empty or missing 'data' field returns a validation error
- Complex or deeply nested AST structures may hit processing limits

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns the result of executing or parsing the provided Python code string within a restricted AST-based sandbox environment, including computed values, parse trees, or error messages if the code is invalid or unsafe.
