pwno-mcp
pwno-mcp runs GDB (with pwndbg) inside an isolated environment and exposes stateful debugging/exploit I/O workflows to LLM agents via an MCP server, with support for multiple sessions and helper automation.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Security-critical: the container run example grants SYS_PTRACE and SYS_ADMIN and relaxes seccomp/apparmor (unconfined). README does not mention authentication/authorization, TLS, or rate limiting for the MCP endpoint, so network exposure should be avoided (use localhost/isolated networks) unless additional hardening exists in the unseen implementation.
⚡ Reliability
Best When
Running locally/privately (e.g., container on a developer machine) where an agent needs stateful debugging and can manage its own session lifecycle.
Avoid When
When you need strong, documented auth/rate limiting for untrusted remote clients, or when container/ptrace privileges cannot be granted safely.
Use Cases
- • Agentic binary exploitation workflows that require interactive debugging
- • Automated register/stack/disassembly/source/backtrace snapshots during analysis
- • Deterministic execution control using GDB/MI for iterative refinement
- • Workspace automation for managing target binaries, processes, and related tooling
- • Parallel agent sessions for concurrent exploit-driver experiments
Not For
- • Production-grade hosted deployments that require strong multi-tenant auth and network hardening
- • Sensitive environments where running GDB/pwndbg with ptrace is unacceptable
- • Use cases needing a public internet API with clear rate-limit/SLA guarantees
Interface
Authentication
README shows an unauthenticated-looking local endpoint and a stdio transport, but does not describe any authentication mechanism, tokens, or access controls for the MCP service.
Pricing
No pricing details provided; README includes license/usage notes but not commercial hosting/pricing for the service itself.
Agent Metadata
Known Gotchas
- ⚠ Requires ptrace-capable container execution (SYS_PTRACE/SYS_ADMIN) which may fail depending on host/container security settings.
- ⚠ Statefulness implies agents must manage session lifecycle correctly to avoid cross-session contamination.
- ⚠ Deterministic control depends on correct GDB/MI usage; agents may need to wait for prompt/response boundaries to avoid desync.
- ⚠ Running untrusted binaries under the debug environment can introduce risk beyond the tool’s API surface.
