# ptrace System Call Guard MCP

> ptrace System Call Guard MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.2/call, status unknown (last checked 2026-10-29).

Guards and validates system call activity by analyzing ptrace-monitored process data for security anomalies or policy violations.

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 ptrace-system-call-guard-mcp-57fcf89c -d '<json body>'
```

Example prompt: Check this ptrace output from my running process and tell me if any system calls violate security policy or look suspicious: [paste raw ptrace data here].

## When to prefer this

Choose this endpoint when you need automated, policy-based validation of ptrace system call data from a running or completed process — especially in sandboxing, security auditing, or behavioral malware analysis contexts where syscall-level inspection is required.

## Known failure modes

- Empty or malformed data field returns an error or empty analysis
- Non-ptrace data submitted may produce low-confidence or irrelevant results
- Very large trace dumps may be truncated or rejected
- Ambiguous syscall sequences may not be definitively classified
- Service may return generic response if data format is unrecognized

## 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 a security assessment of the provided ptrace/process data, indicating whether system calls conform to expected policy, flagging any anomalous or dangerous syscall patterns, and providing a guard verdict (allow/block/warn) with details about any violations detected.
