MCP Server Templates & Integration

Below are example templates for MCP servers using Sigyl. Each example includes a server.ts (or server.js) and a matching sigyl.yaml configuration. Use these as starting points for your own projects. 
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";

export default function createStatelessServer() {
  const server = new McpServer({
    name: "minimal-mcp-server",
    version: "1.0.0",
  });

  server.tool(
    "echo",
    "Echo a string value",
    { value: { type: "string", description: "String to echo" } },
    async ({ value }) => ({ content: [{ type: "text", text: value }] })
  );

  return server.server;
}

import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { z } from "zod";

export default function createStatelessServer({ config }: { config: any }) {
  const server = new McpServer({
    name: "secure-mcp-server",
    version: "1.0.0",
  });

  server.tool(
    "reverseString",
    "Reverse a string value",
    { value: z.string().describe("String to reverse") },
    async ({ value }) => ({
      content: [{ type: "text", text: value.split("").reverse().join("") }],
    })
  );

  // Use config.apiKey or other secrets as needed
  // Example: console.log("API Key:", config.apiKey);

  return server.server;
}

const { McpServer } = require("@modelcontextprotocol/sdk/server/mcp.js");

function createStatelessServer({ config }) {
  const server = new McpServer({
    name: "container-mcp-server",
    version: "1.0.0",
  });

  server.tool(
    "addNumbers",
    "Add two numbers",
    {
      a: { type: "number", description: "First number" },
      b: { type: "number", description: "Second number" },
    },
    async ({ a, b }) => ({
      content: [{ type: "text", text: String(a + b) }],
    })
  );

  return server.server;
}

module.exports = createStatelessServer;
