The open-source safety layer for AI agents.
Block unsafe tool calls. Require approval for risky actions. Enforce budgets. Keep an audit trail. Replay crashed runs.
JamJet sits between your agent and its tools. Use it with LangChain, CrewAI, ADK, OpenAI Agents SDK, MCP — keep your framework, add control.
- jamjet — the safety layer. Python SDK, runtime, policy engine. Start here.
- engram — durable memory for AI agents. Independent product.
- jamjet-runtime-java — JamJet for Spring AI / LangChain4j.
- jamjet-a2a — Agent-to-Agent protocol SDK in Rust.
- JamJet Gateway — an MCP proxy that applies JamJet policy to MCP traffic from Claude Desktop, Cursor, and any MCP-aware agent. See jamjet.dev/gateway.
