Crabtalk
An agent daemon that runs AI agents, dispatches their tools and connects them to MCP servers, treating shell access, file access, skills and session search as sandboxed, independently granted capabilities rather than one open permission set.
Crabtalk is an agent daemon: a background process that runs agents, dispatches their tool calls, and connects them to MCP servers, meant to be started once, talked to, and extended with packages. The daemon itself owns no tools; instead, capabilities such as shell access, file access, skills and session search are harnesses an agent explicitly declares, each isolated so it can only reach what that declaration granted, while calling another program over MCP is treated as using a capability rather than shaping the agent itself.
Other applications, described as agent-powered experiences and standalone services built on top of the daemon, connect to it as independent programs through auto-discovery rather than being built into the daemon.
It is written in Rust, installed with a version manager, and is undergoing a heavy refactor, with its command-line interface being redesigned and not yet in the current tree.
