Tool calling
Run MCP, nested-model, search, and fetch tools inside BitRouter's bounded server-side loop.
1 min readEdit this page
Tool customizations let BitRouter execute selected tool calls and continue the model loop before returning a response. The deployment enables each capability; an individual request still has to opt into it.
Server tools
Understand the loop, its bounds, and the two-gate activation model.
Model-backed tools
Compare Advisor, Sub-agent, and Fusion.
Web tools
Configure Web Search and Web Fetch backends together.
Use MCP gateway when BitRouter should proxy tool servers without owning the model loop. Use server tools when the router itself should advertise, execute, and feed tool results back to the model.
