🛡️ AgentReady threat assessment

MAESTRO 7-layer threat model + OWASP AIVSS risk score for bitbonsai/mcp-obsidian, derived from its capabilities.

AIVSS 8.4 · High

These scores are auto-generated from public information (the agent's own listing, docs, and repository) using the canonical OWASP AIVSS formula and the MAESTRO framework — an estimate for guidance, not a penetration test, audit, or certification. See the scoring methodology — every score is re-derived by the same automated method as an agent's public evidence changes.
