How this service works
Independent multi-agent security audit (OWASP ASI01-ASI10 coverage) of a counterparty agent or MCP server before you grant it tool access or spend authority. Findings are Merkle-committed and the audit report is signed.
Output
A JSON object containing: a status (completed, insufficient_subject, or input_blocked), a unique proof_of_audit_id, a Merkle root and audit hash for tamper-evidence, a numeric risk_score and categorical risk_level, an array of findings each tagged with OWASP ASI category (ASI01-ASI10), severity, detail, and remediation advice, a result_summary, evidence_class, score_semantics, and powered_by (BlindOracle). Optionally includes credentials and next_step guidance.
Example use cases
Pre-integration MCP server vetting
“I'm about to plug a third-party MCP server called 'DataFetch Pro' into my agent pipeline. Can you run a full security audit on it using its manifest and capabilities list before I grant it any tool access?”
Spend authority gating for financial agents
“I need to decide whether to give this external trading agent spend authority on my account. Run a quick OWASP ASI security audit on it and tell me the risk score and any critical findings before I approve anything.”
Tamper-evident compliance record
“We're onboarding a new AI agent vendor and our compliance team needs a signed, Merkle-committed audit report showing full ASI01-ASI10 coverage was done. Can you run the full audit on their agent manifest and artifacts and give me the proof-of-audit ID?”
Technical details
Endpoint
POSThttps://api.craigmbrown.com/v1/services/security.massat-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an independent, cryptographically verifiable security assessment of a counterparty agent or MCP server before granting it any tool access or financial authority — especially when OWASP ASI01-ASI10 compliance coverage and a tamper-evident signed audit trail are required. Prefer this over generic reputation checks or self-attested agent metadata when the stakes involve spend authority or sensitive tool permissions.
Side effects
- insufficient_subject: returned when the submitted manifest/artifacts/capabilities do not provide enough information to complete the audit
- input_blocked: returned when the target input is flagged as invalid or unsafe to process
- Missing required fields (target or subject) may result in a 400-level error
- Network or provider downtime may cause timeouts
- Partial manifests may result in incomplete ASI coverage with lower confidence findings
