Implementation Reference

• src/tools/templates.ts:33-36 (handler)

  The handler function executes the tool logic by making an API request to SendGrid to fetch details of the specified template ID and returns the result as formatted JSON text.

  handler: async ({ template_id }: { template_id: string }): Promise<ToolResult> => {
    const result = await makeRequest(`https://api.sendgrid.com/v3/templates/${template_id}`);
    return { content: [{ type: "text", text: JSON.stringify(result, null, 2) }] };
  },

• src/tools/templates.ts:26-32 (schema)

  The tool configuration including title, description, and Zod input schema for validating the template_id parameter.

  config: {
    title: "Get Template Details",
    description: "Retrieve details of a specific template including all versions",
    inputSchema: {
      template_id: z.string().describe("ID of the template to retrieve"),
    },
  },

• src/index.ts:21-23 (registration)

  The MCP server registration loop that registers the get_template tool (along with all others) by calling server.registerTool with its name, config, and handler.

  for (const [name, tool] of Object.entries(allTools)) {
    server.registerTool(name, tool.config as any, tool.handler as any);
  }

• src/tools/index.ts:16-16 (registration)
