+# MCP TypeScript SDK
+
+## What is MCP?
+
+The Model Context Protocol lets you build servers that expose data and functionality to LLM applications in a secure, standardized way. Think of it like a web API, but specifically designed for LLM interactions. MCP servers can:
+
+- Expose data through **Resources** (think of these sort of like GET endpoints; they are used to load information into the LLM's context)
+- Provide functionality through **Tools** (sort of like POST endpoints; they are used to execute code or otherwise produce a side effect)
+- Define interaction patterns through **Prompts** (reusable templates for LLM interactions)
+
+## Running Your Server
+
+MCP servers in TypeScript need to be connected to a transport to communicate with clients.
+
+```typescript
+import { Server } from "@modelcontextprotocol/sdk/server/index.js";
+import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
+import {
+  ListPromptsRequestSchema,
+  GetPromptRequestSchema
+} from "@modelcontextprotocol/sdk/types.js";
+
+const server = new Server(
+  {
+    name: "example-server",
+    version: "1.0.0"
+  },
+  {
+    capabilities: {
+      prompts: {}
+    }
+  }
+);
+
+server.setRequestHandler(ListPromptsRequestSchema, async () => {
+  return {
+    prompts: [{
+      name: "example-prompt",
+      description: "An example prompt template",
+      arguments: [{
+        name: "arg1",
+        description: "Example argument",
+        required: true
+      }]
+    }]
+  };
+});
+
+server.setRequestHandler(GetPromptRequestSchema, async (request) => {
+  if (request.params.name !== "example-prompt") {
+    throw new Error("Unknown prompt");
+  }
+  return {
+    description: "Example prompt",
+    messages: [{
+      role: "user",
+      content: {
+        type: "text",
+        text: "Example prompt text"
+      }
+    }]
+  };
+});
+
+const transport = new StdioServerTransport();
+await server.connect(transport);
+```

+### HTTP with SSE
+
+For remote servers, start a web server with a Server-Sent Events (SSE) endpoint, and a separate endpoint for the client to send its messages to:
+
+```typescript
+import express from "express";
+import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
+import { SSEServerTransport } from "@modelcontextprotocol/sdk/server/sse.js";
+
+const server = new McpServer({
+  name: "example-server",
+  version: "1.0.0"
+});
+
+// ... set up server resources, tools, and prompts ...
+
+const app = express();
+
+app.get("/sse", async (req, res) => {
+  const transport = new SSEServerTransport("/messages", res);
+  await server.connect(transport);
+});
+
+app.post("/messages", async (req, res) => {
+  // Note: to support multiple simultaneous connections, these messages will
+  // need to be routed to a specific matching transport. (This logic isn't
+  // implemented here, for simplicity.)
+  await transport.handlePostMessage(req, res);
+});
+
+app.listen(3001);
+```

+# Testing Guidelines for TypeScript + ES Modules + Jest
+
+This guide contains cumulative in-context learnings about working with this project's testing stack.
+
+## Unit vs. Integration Tests
+
+**Never Mix Test Types**: Separate integration tests from unit tests into different files:
+   - Simple unit tests without mocks for validating rules (like state transitions)
+   - Integration tests with mocks for filesystem and external dependencies
+
+## File Path Handling in Tests
+
+1. **Environment Variables**:
+   - Use `process.env.TASK_MANAGER_FILE_PATH` for configuring file paths in tests
+   - Set this in `beforeEach` and clean up in `afterEach`:
+     ```typescript
+     beforeEach(async () => {
+       tempDir = path.join(os.tmpdir(), `test-${Date.now()}`);
+       await fs.mkdir(tempDir, { recursive: true });
+       tasksFilePath = path.join(tempDir, "test-tasks.json");
+       process.env.TASK_MANAGER_FILE_PATH = tasksFilePath;
+     });
+
+     afterEach(async () => {
+       await fs.rm(tempDir, { recursive: true, force: true });
+       delete process.env.TASK_MANAGER_FILE_PATH;
+     });
+     ```
+
+2. **Temporary Files**:
+   - Create unique temp directories for each test run
+   - Use `os.tmpdir()` for platform-independent temp directories
+   - Include timestamps in directory names to prevent conflicts
+   - Always clean up temp files in `afterEach`
+
+## Jest ESM Mocking, Step-by-Step
+
+1. **Type-Only Import:**  
+   Import types for static analysis without actually executing the module code:
+   ```typescript
+   import type { MyService as MyServiceType } from 'path/to/MyService.js';
+   import type { readFile as ReadFileType } from 'node:fs/promises';
+   ```
+
+2. **Register Mock:**  
+   Use `jest.unstable_mockModule` to replace the real module:
+   ```typescript
+   jest.unstable_mockModule('node:fs/promises', () => ({
+     __esModule: true,
+     readFile: jest.fn(),
+   }));
+   ```
+
+3. **Set Default Mock Implementations, Then Dynamically Import Modules:**  
+   You must dynamically import the modules to be mocked and/or tested *after* registering mocks and setting any mock implementations. This ensures that when `MyService` attempts to import `node:fs/promises`, it gets your mocked version. Depending how you want to scope your mock implementations, you can do this in `beforeAll`, `beforeEach`, or at the top of each test.
+   ```typescript
+   let MyService: typeof MyServiceType;
+   let readFile: jest.MockedFunction<ReadFileType>;
+
+   beforeAll(async () => {
+     const fsPromisesMock = await import('node:fs/promises');
+     readFile = fsPromisesMock.readFile as jest.MockedFunction<ReadFileType>;
+
+     // Set default implementation
+     readFile.mockResolvedValue('default mocked content');
+
+     const serviceModule = await import('path/to/MyService.js');
+     MyService = serviceModule.MyService;
+   });
+   ```
+
+4. **Setup in `beforeEach`:**  
+   Reset mocks and set default behaviors before each test:
+   ```typescript
+   beforeEach(() => {
+     jest.clearAllMocks();
+     readFile.mockResolvedValue('');
+   });
+   ```
+
+5. **Write a Test:**  
+   Now you can test your service with the mocked `readFile`:
+   ```typescript
+   describe('MyService', () => {
+     let myServiceInstance: MyServiceType;
+
+     beforeEach(() => {
+       myServiceInstance = new MyService('somePath');
+     });
+
+     it('should do something', async () => {
+       readFile.mockResolvedValueOnce('some data');
+       const result = await myServiceInstance.someMethod();
+       expect(result).toBe('expected result');
+       expect(readFile).toHaveBeenCalledWith('somePath', 'utf-8');
+     });
+   });
+   ```
+
+### Mocking a Class with Methods
+
+If you have a class `MyClass` that has both instance methods and static methods, you can mock it in an **ES Modules + TypeScript** setup using the same pattern. For instance:
+
+```typescript
+// 1. Create typed jest mock functions using the original types
+type InitResult = { data: string };
+
+const mockInit = jest.fn() as jest.MockedFunction<MyClass['init']>;
+const mockDoWork = jest.fn() as jest.MockedFunction<MyClass['doWork']>;
+const mockStaticHelper = jest.fn() as jest.MockedFunction<typeof MyClass.staticHelper>;
+
+// 2. Use jest.unstable_mockModule with an ES6 class in the factory
+jest.unstable_mockModule('path/to/MyClass.js', () => {
+  class MockMyClass {
+    // Instance methods
+    init = mockInit;
+    doWork = mockDoWork;
+
+    // Static method
+    static staticHelper = mockStaticHelper;
+  }
+
+  return {
+    __esModule: true,
+    MyClass: MockMyClass, // same name/structure as real export
+  };
+});
+
+// 3. Import your class after mocking
+let MyClass: typeof import('path/to/MyClass.js')['MyClass'];
+
+beforeAll(async () => {
+  const myClassModule = await import('path/to/MyClass.js');
+  MyClass = myClassModule.MyClass;
+});
+
+// 4. Write tests and reset mocks
+beforeEach(() => {
+  jest.clearAllMocks();
+  mockInit.mockResolvedValue({ data: 'default' });
+  mockStaticHelper.mockReturnValue(42);
+});
+
+describe('MyClass', () => {
+  it('should call init', async () => {
+    const instance = new MyClass();
+    const result = await instance.init();
+    expect(result).toEqual({ data: 'default' });
+    expect(mockInit).toHaveBeenCalledTimes(1);
+  });
+
+  it('should call the static helper', () => {
+    const val = MyClass.staticHelper();
+    expect(val).toBe(42);
+    expect(mockStaticHelper).toHaveBeenCalledTimes(1);
+  });
+});
+```
+
+### Best Practice: **Type** Your Mocked Functions
+
+By default, `jest.fn()` is very generic and doesn't enforce parameter or return types. This can cause TypeScript errors like:
+
+> `Argument of type 'undefined' is not assignable to parameter of type 'never'`
+
+or
+
+> `Type 'Promise<SomeType>' is not assignable to type 'FunctionLike'`
+
+To avoid these, **use the original type with `jest.MockedFunction`**. For example, if your real function is:
+
+```typescript
+async function loadStuff(id: string): Promise<string[]> {
+  // ...
+}
+```
+
+then you should type the mock as:
+
+```typescript
+const mockLoadStuff = jest.fn() as jest.MockedFunction<typeof loadStuff>;
+```
+
+For class methods, use the class type to get the method signature:
+
+```typescript
+const mockClassMethod = jest.fn() as jest.MockedFunction<YourClass['classMethod']>;
+```
+
+This helps TypeScript catch mistakes if you:
+- call the function with the wrong argument types
+- use `mockResolvedValue` with the wrong shape
+
+Once typed properly, your `mockResolvedValue(...)`, `mockImplementation(...)`, etc. calls will be fully type-safe.
