Fine vs Syrin - Static Contract Analysis for MCP Servers

Build Software with AI Agents.

• 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%.
