Hi HN. I built Modex, a Clojure MCP library to augment your AI models with new Tools, Resources (WIP) and Prompts (WIP).

Modex implements the MCP stdio transport and JSON-RPC wire format, which means it does not need an MCP proxy or any Anthropic Java SDK dependencies to be called from most MCP clients.

At work I am using Modex to build simple tools like datomic-mcp[^1] that lets MCP clients like Claude Desktop diagnose support issues against our production Datomic databases.

For example, when a customer opens a support ticket about their VM being unreachable, Claude will inspect our Datomic schema, figure out which queries to run to check server state, try to reach the VM using an MCP ping tool and check the state of the host and VM in our cluster. Over time we hope to automate the bulk of recurring support queries using Modex and other MCP tools.

this is pretty cool man. where can i follow your progress?

Hi @RCKarel12345, the easiest is probably to subscribe / follow the GH repo: https://github.com/theronic/modex

I'll post about new features on my X account.
