Implementation Reference

• packages/mcp/src/tools/routing.ts:12-29 (handler)

  The handler function for the "routing" tool, which either sets or gets the routing strategy via the API client.

  export async function handleRouting(
    input: RoutingInput,
    client: RhumbApiClient
  ): Promise<RoutingOutput> {
    const action = input.action || "get";
  
    if (action === "set" && input.strategy) {
      const result = await client.setRoutingStrategy(
        input.strategy,
        input.quality_floor,
        input.max_cost_per_call_usd
      );
      return result as unknown as RoutingOutput;
    }
  
    const result = await client.getRoutingStrategy();
    return result as unknown as RoutingOutput;
  }

• packages/mcp/src/server.ts:259-275 (registration)

  Registration of the "routing" tool in the Rhumb MCP server.

  // -- routing ----------------------------------------------------------
  server.tool(
    "routing",
    "Get or set how Rhumb auto-selects providers when you don't specify one in execute_capability. Controls the tradeoff between cost, speed, and quality. Also sets a quality floor (minimum AN Score) and optional per-call cost ceiling.",
    {
      action: z.string().optional().describe(RoutingInputSchema.properties.action.description),
      strategy: z.string().optional().describe(RoutingInputSchema.properties.strategy.description),
      quality_floor: z.number().optional().describe(RoutingInputSchema.properties.quality_floor.description),
      max_cost_per_call_usd: z.number().optional().describe(RoutingInputSchema.properties.max_cost_per_call_usd.description)
    },
    async ({ action, strategy, quality_floor, max_cost_per_call_usd }) => {
      const result = await handleRouting({ action, strategy, quality_floor, max_cost_per_call_usd }, client);
      return {
        content: [{ type: "text" as const, text: JSON.stringify(result) }]
      };
