A local MCP daemon that turns an agentic coding client into a bug bounty operator, with 103 tools for offensive security testing including MITM proxy, traffic analysis, and OOB callbacks.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
Forge has a basicConstraints bypass in its certificate chain verification (RFC 5280 violation)
node-forge has ASN.1 Unbounded Recursion
node-forge has an Interpretation Conflict vulnerability via its ASN.1 Validator Desynchronization
Forge has Denial of Service via Infinite Loop in BigInteger.modInverse() with Zero Input
Forge has signature forgery in RSA-PKCS due to ASN.1 extra field

Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
2/2 tools missing one or more hints — box_targets (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); box_use_target (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
1/2 tools referenced in tests (50%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 7 high severity in production deps — node-forge@1.3.1 (high), node-forge@1.3.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dependency freshness
2/26 production deps stale: proper-lockfile@2022-06-24 (4.1y), acme-client@2024-07-16 (2.1y)

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
