@sapiom/mcp@0.17.0
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 1mo ago · by lpm-firewall-aiStatic inspection found no lifecycle hook, self-dependency, stealth persistence, or concrete malicious behavior. Networked and destructive operations are aligned with the declared MCP service and are user-invoked.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user starts the sapiom-mcp command and invokes an MCP tool.
Impact
No unconsented installation-time mutation, secret harvesting, or confirmed exfiltration was found.
Mechanism
Authentication uses a loopback callback; management actions require authenticated credentials and destructive deletion requires confirmation.
AI rationale
Static inspection found no lifecycle hook, self-dependency, stealth persistence, or concrete malicious behavior. Networked and destructive operations are aligned with the declared MCP service and are user-invoked.

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exposes a command entrypoint and contains no automatic install lifecycle hook.
- The browser authentication callback listens only on loopback.
- The destructive App Link deletion tool requires an explicit confirmation value.
