tech.unravel/example-cool-mcp-server

I'm an MCP server generator template for Clojure programmers. Use me on Github for creating your cool new MCP servers.

Here is how you should use this template:

1. [ ] Click the 'Use this template' button to create your server project

2. [ ] Replace tech.unravel with your group-id throughout the project, and in the directory structure as well

3. [ ] Replace example-cool-mcp-server with the actual name of your server throughout the project

4. [ ] Replace /Users/vedang/repo-name with the full-path on your local disk, when testing your server

5. [ ] Add the logic of your server in src/tech/unravel/example_cool_mcp_server.clj file (Remember that you will have changed the name of this file). This file contains a full stub already, to help you get started.

Usage

Building the Uberjar

1. make clean && make build

Running the MCP server

Some example commands you can try in Claude Desktop or Inspector:

1. Visualize this data for me using ...

2. Add the prompts you would use to test your server in this section

Before running the MCP server

Remember:

1. Replace the full-path to the tech.unravel/example-cool-mcp-server JAR with the correct path on your system (i.e. replace /Users/vedang/repo-name below with the correct path)

2. Other notes specific to your server should go here.
