Fuzz Breaker
Run automated API pentesting and structural fuzzing from your agent before you expose endpoints to paying users.
Overview
Fuzz-Breaker is an MCP server for the Ship phase that runs automated API pentesting and structural fuzzing through a remote agent integration.
What is this MCP server?
- Automated API pentesting via MCP remote SSE (fuzz-breaker-mcp.vercel.app, v1.0.0)
- Structural fuzzing proxy for discovering API weakness patterns
- Optional EIP-3009 payment-signature for premium settlement
- Agent-invokable security checks without maintaining a separate fuzz harness repo
- Published server version 1.0.0
- 1 remote SSE endpoint on Vercel
- Described capability: automated API pentesting plus structural fuzzing proxy
What problem does it solve?
Solo builders ship REST and GraphQL APIs without time to run consistent fuzzing or pentest passes before launch.
Who is it for?
API-first indie products needing agent-driven security passes before launch or after large endpoint refactors.
Skip if: Builders without APIs to test, or teams that require certified pen tests and formal audit reports only humans can sign.
What do I get? / Deliverables
Your agent can trigger structural API fuzzing and pentest-style probing so fewer obvious exploit classes reach production.
- Agent-triggered API pentest and fuzzing sessions
- Structural weakness signals for pre-launch fixes
- Documented MCP hook for recurring Ship security checks

How it compares
MCP API fuzzing and pentest proxy, not a unit-test runner skill or infrastructure scanner.
Common Questions / FAQ
Who is Fuzz Breaker for?
Solo developers and small teams shipping APIs who want MCP-connected automated pentesting and fuzzing from their coding agent.
When should I use Fuzz Breaker?
Use it in Ship security review before go-live, after auth or schema changes, or when adding new public routes to an existing API.
How do I add Fuzz Breaker to my agent?
Register https://fuzz-breaker-mcp.vercel.app/api/mcp as an SSE MCP server; configure payment-signature if premium access requires EIP-3009 authorization.
