Implementation Reference

• src/tools/consulTools.ts:597-615 (handler)

  The asynchronous handler function that implements the core logic of the 'create-prepared-query' tool by calling consul.query.create to create a prepared query in Consul and handling the response or errors.

  async ({ name, service, nearestN, datacenters }) => {
    try {
      // @ts-ignore - The Consul type definitions are incomplete
      const query = await consul.query.create({
        Name: name,
        Service: {
          Service: service,
          Failover: {
            NearestN: nearestN || 3,
            Datacenters: datacenters || [],
          },
        },
      }) as PreparedQuery;
      return { content: [{ type: "text", text: `Created prepared query: ${query.ID}` }] };
    } catch (error) {
      console.error("Error creating prepared query:", error);
      return { content: [{ type: "text", text: `Error creating prepared query: ${name}` }] };
    }
  }

• src/tools/consulTools.ts:591-596 (schema)

  Zod schema defining the input parameters for the 'create-prepared-query' tool, including name, service, nearestN, and datacenters.

  {
    name: z.string().default("").describe("Name of the prepared query"),
    service: z.string().default("").describe("Service to query"),
    nearestN: z.number().optional().describe("Number of nearest nodes to return"),
    datacenters: z.array(z.string()).optional().describe("Datacenters to query"),
  },

• src/tools/consulTools.ts:588-616 (registration)

  The server.tool call that registers the 'create-prepared-query' tool with its description, input schema, and handler function.

  server.tool(
    "create-prepared-query",
    "Create a new prepared query",
    {
      name: z.string().default("").describe("Name of the prepared query"),
      service: z.string().default("").describe("Service to query"),
      nearestN: z.number().optional().describe("Number of nearest nodes to return"),
      datacenters: z.array(z.string()).optional().describe("Datacenters to query"),
    },
    async ({ name, service, nearestN, datacenters }) => {
      try {
        // @ts-ignore - The Consul type definitions are incomplete
        const query = await consul.query.create({
          Name: name,
          Service: {
            Service: service,
            Failover: {
              NearestN: nearestN || 3,
              Datacenters: datacenters || [],
            },
          },
        }) as PreparedQuery;
        return { content: [{ type: "text", text: `Created prepared query: ${query.ID}` }] };
      } catch (error) {
        console.error("Error creating prepared query:", error);
        return { content: [{ type: "text", text: `Error creating prepared query: ${name}` }] };
      }
    }
  );

• src/tools/consulTools.ts:42-52 (schema)

  TypeScript interface defining the structure of a PreparedQuery response from Consul, used in the tool's handler.

  interface PreparedQuery {
    ID: string;
    Name: string;
    Service: {
      Service: string;
      Failover: {
        NearestN: number;
        Datacenters: string[];
      };
    };
  }
