@sapiom/mcp@0.20.0
Local Sapiom developer MCP server (sapiom-dev) — the unmetered surface for building and operating on Sapiom; today it scaffolds, tests, deploys, and inspects orchestrations. Not the remote Sapiom capability MCP.
AI Security Review
scanned 25d ago · by lpm-firewall-aiDirect inspection found no install hook or concrete malicious behavior. The scanner's agent-configuration hint identifies a skipped directory, while the flagged process use is consistent with the package's browser authentication and project-scanning functions.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Normal use of the MCP server, its authentication flow, or its project-scanning tools.
Impact
No malicious effect was established from the inspected behavior.
Mechanism
Authentication uses a local browser callback and exchanges the returned code with the configured API; project scanning excludes selected directories.
AI rationale
Direct inspection found no install hook or concrete malicious behavior. The scanner's agent-configuration hint identifies a skipped directory, while the flagged process use is consistent with the package's browser authentication and project-scanning functions.
Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json exposes the MCP entrypoint and command; it has no install lifecycle hook.
- The flagged project scanner skips common generated and fixture directories and bounds discovery depth.
- The authentication code exchanges a browser-returned authorization code with the configured API URL.
- App management reads credentials and only sends a settings update when the caller supplies changes.
Evidence against
- The inspected authentication code uses a local callback and sends the authorization code to the configured API URL; the flagged process use is consistent with browser launch and project scanning.
- The agent-configuration hint points to a directory exclusion in the scanner, not a write to agent configuration.
