Api Payload Auditor
Audit API request and response payloads from your agent before release to catch leaks, unsafe fields, and contract drift.
Overview
api-payload-auditor is a MCP server for the Ship phase that lets your agent audit API payloads for safety and consistency via a Cloudflare Workers endpoint.
What is this MCP server?
- MCP server on Cloudflare Workers for payload auditing workflows
- Streamable-HTTP remote for Claude Code, Cursor, and compatible clients
- Fits pre-release API reviews alongside manual code review
- Open repository api-payload-auditor-api on GitHub
- Part of lazymac2x API toolkit with flow analyzer and mock server
- Server manifest version 1.0.0
- Single remote MCP URL: api.lazy-mac.com/api-payload-auditor/mcp
- Source repository: github.com/lazymac2x/api-payload-auditor-api on Cloudflare Workers
What problem does it solve?
You are about to ship API endpoints but cannot easily spot PII leaks, oversized fields, or schema mismatches in real payloads.
Who is it for?
Solo builders shipping APIs or webhooks who want agent-assisted payload review without a full security platform.
Skip if: Organizations that need certified pentests, SOC2-ready scanning suites, or offline-only security tooling.
What do I get? / Deliverables
Your agent runs MCP-backed payload audits so you fix data-handling issues before production traffic hits your API.
- Agent-guided payload audit findings for your API surfaces
- Reduced risk of shipping leaky or malformed request/response bodies
- Actionable fixes aligned to integration code before launch

How it compares
MCP payload auditor for APIs, not a general code-review skill or enterprise DAST appliance.
Common Questions / FAQ
Who is api-payload-auditor for?
Developers shipping HTTP APIs who use MCP agents and want an extra pass on request/response payloads for security and correctness.
When should I use api-payload-auditor?
Use it in the ship phase during security and launch prep when payloads are stable enough to audit but before you expose endpoints publicly.
How do I add api-payload-auditor to my agent?
Register https://api.lazy-mac.com/api-payload-auditor/mcp as streamable-HTTP MCP in your client, then invoke auditor tools with sample or captured payloads.
