The hub that links everything — a plugin hub in Rust: contract center · registry & discovery · declarative orchestration · event bus · MCP tool surface · vision
The web console (ships in this repo): the plugin catalog with live instances and the aggregated MCP tool surface. Thirteen pages — flow editor, trace waterfall, governance — see Console.
plugin-hub is the control hub for an out-of-process plugin architecture. The core only provides the "socket" and contains no business semantics: every business capability is supplied by a plugin — a separate container exposing a gRPC interface, in any language (Go SDK by default). Register and it is usable immediately, with no hub restart.
It targets this class of problem: many business systems need a single access point, contract changes need to be controlled, call chains need to be observable, and AI agents need to reach all of it through MCP — while business code keeps its own deployment, its own stack, and its own release cadence.

Feature What it means ------ Field-level contract governance Plugins submit a proto descriptor at registration; the hub runs field-level compatibility checks — adding an optional field passes, deleting a field / changing a type / renumbering a tag is rejected. Contract drift is stopped at registration time, not at runtime. Declarative orchestration DAG flows: drag-and-dr
