Doberman features

  • MCP proxy. Intercepts every tool call from an agent and normalizes it into a SecurityObject.
  • Three-verdict engine. Deterministic core returns PASS, AUTH (human approval) or BLOCK before execution.
  • Raise-only learning. Behavioral baselines can only tighten; weakening requires 2FA-gated approval.
  • Mode dial. Four security postures (Light, Balanced, Strict, Paranoid) adjust thresholds and default verdicts.
  • Tiered authentication. Local confirmation, TOTP 2FA, and time-limited role elevation for AUTH actions.
  • Local audit log. Append-only, redacted log of decisions with reason codes and HMAC fingerprints.
  • Extensible plugins. Custom detectors, auth providers, or audit sinks can be added via Python entry points.
  • Fail-closed default. Any error, uncertainty or unknown case results in a BLOCK verdict.

LangChain features

  • Build agents fast. Start with proven patterns, customize harness, context, memory and model choice.
  • Trace-based testing. Debug runs with step-by-step tracing and query complex traces instantly.
  • Managed deployments. Deploy long-running agents with serverless or dedicated sandboxes and 30+ endpoints.
  • Production monitoring. Online evals, dashboards and alerts track quality, cost, latency and errors.
  • Feedback loop engine. Automatically detect issues, diagnose root causes and feed fixes back into evals.
  • Governance controls. Enforce cost limits, data redaction and human approval via LLM Gateway.
