Tools & capabilities

Agent Security Scanner MCP tools 23

  • scan_securityScan a file for security vulnerabilities. Use verbosity='minimal' for counts only (~50 tokens), 'compact' (default) for actionable info (~200 tokens), 'full' for complete metadata.
  • fix_securityScan a file and return fixes. Use verbosity='minimal' for summary only, 'compact' (default) for fix list, 'full' for complete fixed file content.
  • record_security_outcomeRecord aggregate remediation outcomes after reviewing scanner findings. Sends counts only; never sends code, findings, paths, or rule IDs.
  • list_security_rulesList all available security fix templates and their descriptions
  • check_packageCheck if a package name is legitimate or potentially hallucinated (AI-invented)
  • scan_packagesScan code for package imports and check for hallucinated (AI-invented) packages. Use verbosity='minimal' for counts, 'compact' (default) for flagged packages, 'full' for all details.
  • list_package_statsList statistics about loaded package lists for hallucination detection
  • scan_agent_promptScan a prompt for malicious intent. Returns BLOCK/WARN/LOG/ALLOW. Use verbosity='minimal' for action only, 'compact' (default) for findings, 'full' for audit details.
  • scan_git_diffScan git diff for new security vulnerabilities. Only reports issues on changed lines. Use for PR reviews.
  • scan_projectScan an entire directory for security vulnerabilities with .gitignore support and security grading. Use verbosity='minimal' for grade + counts, 'compact' (default) for top issues, 'full' for all details.
  • scan_agent_actionPre-execution security check for agent actions (bash, file_write, file_read, http_request, file_delete, cron, process_spawn, git, docker). Returns ALLOW/WARN/BLOCK.
  • scan_mcp_serverScan an MCP server's source code for security vulnerabilities: overly broad permissions, missing input validation, data exfiltration, insecure patterns. Returns grade (A-F) and recommendations.

  • verify_agent_scopeCheck whether this agent is authorised to perform an action before executing it. Verifies the active X.509 certificate, permitted_actions scope, financial limits, and revocation status.
  • check_risk_scoreRetrieve the agent's rolling 30-day risk score, band (`low`/`medium`/`high`), drift trend, and actionable guidance. No input required.
  • audit_log_appendAppend a behavioral event to the agent's immutable audit log. Returns risk score + transaction ID. Events scoring ≥ 0.85 auto-trigger a certificate revocation check.
