CrabTalkCrabTalk Documentation
Build and run autonomous AI agents with CrabTalk — a Rust-powered composable agent runtime.
CrabTalk is an open-source agent runtime that runs autonomous AI agents on your machine. Built in Rust, it connects to LLM providers and dispatches tools through composable extensions.

How it works
CrabTalk runs a background daemon that manages agents, routes events, and dispatches tool calls. You interact with agents through the CLI, or connect them to Telegram via the gateway service.
[Sources] ──→ [Event Loop] ──→ [Agents]
Socket (UDS) mpsc channel Agent 1
Socket (TCP) Agent 2
Gateway ...
Tool callsEvery event flows through a single mpsc::unbounded channel. The event loop dispatches each event as its own async task — agents never block each other.
Architecture
The runtime is composed of focused crates:
| Crate | Purpose |
|---|---|
crabtalk-core | Agent execution, runtime, sessions, hooks, model trait |
crabtalk-model | LLM providers (OpenAI, Claude, DeepSeek, Ollama) |
crabtalk-daemon | Background service, tasks, permissions, event loop, service manager |
crabtalk-socket | Unix domain socket transport |
crabtalk-tcp | TCP transport |
crabtalk-cli | CLI interface and REPL |
Each crate can be used independently. The daemon composes them all into a running system.
What you can do
- Connect to model providers — OpenAI, Claude, DeepSeek, Ollama, and more
- Give agents access to your filesystem and shell
- Extend agents with skills and MCP servers
- Deploy bots on Telegram via the gateway service
- Extend with extensions for search and custom capabilities
- Delegate work across agents with multi-agent tasks
