Pipelock features
- Fixed-order scanner pipeline. Detects secret leaks, prompt injection, SSRF and tool poisoning using 65 DLP patterns.
- Kill-switch enforcement. Six independent sources can instantly block traffic with fail-closed behavior.
- Process sandboxing. Uses Landlock, seccomp (Linux) and sandbox-exec (macOS) to contain agent processes.
- Signed receipts. Generates Ed25519-signed decision logs that can be verified offline.
- Multi-profile coordination. Pro tier adds unlimited named security profiles with separate policies and budgets.
- Observability integrations. Exports 85+ Prometheus metrics and supports OTLP, Grafana, Splunk, etc.
Syrin - Static Contract Analysis for MCP Servers features
- First-class budget enforcement. Set dollar limits per agent; stop, warn or switch models when the budget is exceeded.
- Budget-aware persistent memory. Four memory types with decay, import-rank and token-cost awareness, persisting across sessions.
- Isolated sandbox execution. Run LLM-generated Python, Bash or JavaScript in subprocesses with timeouts and no shared state.
- 72+ lifecycle hooks. Typed events fire on every LLM request, tool call, memory read, sandbox exec, etc., for observability.
- Built-in guardrails. PII redaction, prompt-injection detection, content filtering, fact verification and output length limits.
- Multi-agent orchestration. Swarm topologies and recursive sub-agent spawning share budget, memory and observability.
- Agent identity & signing. Each agent has a cryptographic Ed25519 identity; messages are signed to prevent impersonation.
- Token-Oriented Object Notation (TOON). Compact schema format reduces token usage on tool calls by ~40%.
