Meerkat - Rust Agentic Interface Kit

A minimal, high-performance agent harness for LLM-powered applications.

Architecture

All production surfaces (CLI, REST, RPC, MCP) use the runtime-backed path: SessionService (substrate) + RuntimeSessionAdapter (control plane). The runtime owns keep-alive, Queue/Steer routing, comms drain, and ingress.

build_ephemeral_service is available for testing and embedded use where runtime semantics (keep-alive, Steer, comms-driven admission) are not needed. It supports Queue-only turns and will reject Steer/render_metadata.

For the runtime-backed entry point, see [meerkat_rpc::SessionRuntime] or the REST/MCP server crates.
