@sapiom/mcp@0.19.2
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 29d ago · by lpm-firewall-aiThe scanner’s reverse-shell and agent-configuration hints do not match the inspected behavior: the process call opens a browser, and the `.claude` reference only skips that directory. The package manifest has no install lifecycle hook, and the inspected authentication and app-management behavior is consistent with its CLI purpose.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user invokes the authentication tool or app-management tool.
Impact
No malicious impact was established from the inspected source.
Mechanism
Authentication opens the configured Sapiom login page and exchanges its returned authorization code; app management registers settings for published App Links.
AI rationale
The scanner’s reverse-shell and agent-configuration hints do not match the inspected behavior: the process call opens a browser, and the `.claude` reference only skips that directory. The package manifest has no install lifecycle hook, and the inspected authentication and app-management behavior is consistent with its CLI purpose.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json defines a CLI entry point and has no install lifecycle script.
- The `.claude` directory appears in a scanner skip list; this location does not configure an agent.
- The browser process is launched by the authentication flow, which stores credentials returned by that flow.
- Authentication exchanges a code with the configured Sapiom API endpoint.
- The flagged app-management code registers a tool for changing published App Link settings.
