- 02Example MCP tool
- 03Generate tools with the CLI
- 04Build and publish with npm
- 05Claude Desktop configuration
Use cases
- 01Learn the structure of an MCP server
- 02Add tools to a server project
- 03Build and test a server locally
- 04Publish a server for use with Claude Desktop
MCP support
Implements an MCP server with tools defined in the project. The README explains how to add it to Claude Desktop locally or after publishing.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Adding Components
The project comes with an example tool in src/tools/ExampleTool.ts. You can add more tools using the CLI:
# Add a new tool
mcp add tool my-tool
# Example tools you might create:
mcp add tool data-processor
mcp add tool api-client
mcp add tool file-handler
Tool Development
Example tool structure:
import { MCPTool } from "mcp-framework";
import { z } from "zod";
interface MyToolInput {
message: string;
}
class MyTool extends MCPTool<MyToolInput> {
name = "my_tool";
description = "Describes what your tool does";
schema = {
message: {
type: z.string(),
description: "Description of this input parameter",
},
};
async execute(input: MyToolInput) {
// Your tool logic here
return `Processed: ${input.message}`;
}
}
export default MyTool;
Publishing to npm
-
Update your package.json:
- Ensure
nameis unique and follows npm naming conventions - Set appropriate
version - Add
description,author,license, etc. - Check
binpoints to the correct entry file
- Ensure
-
Build and test locally:
npm run build npm link my-mcp-server # Test your CLI locally -
Login to npm (create account if necessary):
npm login -
Publish your package:
npm publish
After publishing, users can add it to their claude desktop client (read below) or run it with npx
## Using with Claude Desktop
### Local Development
Add this configuration to your Claude Desktop config file:
**MacOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
**Windows**: `%APPDATA%/Claude/claude_desktop_config.json`
```json
{
"mcpServers": {
"my-mcp-server": {
"command": "node",
"args":["/absolute/path/to/my-mcp-server/dist/index.js"]
}
}
}
After Publishing
Add this configuration to your Claude Desktop config file:
MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%/Claude/claude_desktop_config.json
{
"mcpServers": {
"my-mcp-server": {
"command": "npx",
"args": ["my-mcp-server"]
}
}
}
Building and Testing
- Make changes to your tools
- Run
npm run buildto compile - The server will automatically load your tools on startup

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
