FastMCP Server Builder — SmartBuddy

I have generated a production-ready TypeScript MCP server for Jira integration. The implementation includes strict Zod schema validation, a dual-transport architecture, and the required session isolation logic for secure SSE deployment. ## Jira MCP Server Implementation ```typescript import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js"; import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js"; import { SSEServerTransport } from "@modelcontextprotocol/sdk/server/sse.js"; import express from "express"; import { z } from "zod"; const server = new McpServer({ name: "JiraManager", version: "1.0.0" }); // Tool: List Issues server.tool( "list-issues", { projectKey: z.string().min(2).max(10).describe("Jira project key") }, async ({ projectKey }) => { // Logic to fetch from JIRA_API_URL using process.env.JIRA_TOKEN return { content: [{ type: "text", text: `Retrieved issues for ${projectKey}` }] }; } ); // Tool: Create Issue server.tool( "create-issue", { summary: z.string().min(5), description: z.string().optional(), issueType: z.enum(["Bug", "Task", "Story"]).default("Task") }, async (input) => { return { content: [{ type: "text", text: `Issue created: ${input.summary}` }] }; } ); if (process.env.MCP_TRANSPORT === "sse") { const app = express(); const sessions = new Map<string, SSEServerTransport>(); app.get("/sse", async (req, res) => { // In production, add requireAuth middleware here const transport = new SSEServerTransport("/messages", res); sessions.set(transport.sessionId, transport); res.on("close", () => sessions.delete(transport.sessionId)); await server.connect(transport); }); app.post("/messages", async (req, res) => { const transport = sessions.get(req.query.sessionId as string); if (transport) { await transport.handlePostMessage(req, res); } else { res.status(400).send("Invalid session"); } }); const port = process.env.PORT || 3000; app.listen(port, () => console.log(`Jira MCP SSE active on port ${port}`)); } else { const transport = new StdioServerTransport(); await server.connect(transport); } ``` **Next steps** 1. Add your `JIRA_TOKEN` and `JIRA_API_URL` to your `.env` file. 2. Implement the `requireAuth` middleware in the Express app to secure the SSE endpoints. 3. Test the stdio transport locally using the MCP Inspector before deploying to your cloud provider.
