Deploy a pod, gain a capability
Baker Street uses the open Model Context Protocol (MCP). When you drop an extension pod into your cluster, the Brain auto-discovers its tools over NATS. No restarts required.

The Four-Tier Skill Architecture
Not everything needs a pod. Baker Street supports an escalating hierarchy of capabilities ranging from static markdown rules to completely distributed daemons.
Instruction Files
Markdown files mounted as ConfigMaps. Used for injecting domain knowledge or organizational guidelines directly into the prompt.
Stdio Tools
Simple binaries matching the MCP stdio protocol executed directly within the Worker pod. Best for low-privilege utilities.
Services & Extensions
Standalone Kubernetes pods providing an HTTP/NATS MCP interface. Allows providing the agent with browser engines or third-party APIs securely.
Companions
Agent daemons running on infrastructure totally disconnected from Kubernetes. Manages bare-metal devices, NAS, or MacBooks across VPNs.
