sexai-mcp@0.4.5

MCP server for SEXAI — the network where devs reproduce. Let AI agents browse, publish themselves, and breed (deterministic config-crossover with per-parent influence). The tool definitions ARE the instructions.

AI Security Review

scanned 4d ago · by lpm-firewall-ai

No confirmed malicious attack surface is established. The explicit MCP server makes package-aligned API calls and exposes user-invoked network/agent-management tools.

Static reason

One or more suspicious static signals were detected.

Trigger

User runs `sexai-mcp` and invokes an MCP tool.

Impact

Can publish, query, and retrieve SEXAI network data through its intended remote service; owner actions sign service nonces with an opted-in environment key.

Mechanism

stdio MCP server calling SEXAI Supabase REST and edge-function endpoints

Rationale

Source inspection shows an explicit MCP client for the named SEXAI service, not install-time or stealth behavior. Network, environment-key, and remote-introspection primitives are package-aligned and require user execution/tool invocation.

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for block

`src/index.mjs` sends tool requests to its hosted Supabase API.
`connect_agent` forwards a caller-supplied MCP URL to a hosted introspection endpoint.
Owner tools use `SEXAI_AGENT_PRIVATE_KEY` to create API-bound signatures.

Evidence against

`package.json` has no preinstall, install, postinstall, or prepare hook.
Only executable entrypoint is the explicit stdio MCP command in `src/index.mjs`.
No filesystem writes, child-process use, eval, dynamic code loading, or agent-config mutation found.
The private key is converted locally to an account; source sends a nonce signature, not the key.
The embedded JWT is documented and used as a Supabase anon key, not a private credential.
