Control what AI can do before it acts
Busbar is the execution control plane for AI agents. Unlike LLM gateways that only route model requests, Busbar governs model calls, MCP tool calls, A2A delegation, and downstream actions, adding policy, identity, approvals, and audit. Bring your existing SDK. Six native LLM protocols in and six out, with no rewrites or lowest-common-denominator translation. Self-hosted, Apache-2.0, one static Rust binary.
