概要

What is Datomic MCP Server?

It is an MCP server that integrates Datomic databases with the Model Context Protocol, enabling LLM-powered applications to execute Datomic queries and operations. Built with Modex, it supports concurrent queries and exposes core Datomic API functions as MCP tools. It is designed for developers building AI assistants that need to interact with Datomic data.

How to use Datomic MCP Server?

Run the provided Java uberjar and configure the DATOMIC_URI environment variable in your MCP client settings (e.g., Claude Desktop). The server currently supports query, datoms, with, pull, pull-many, entity, touch, and entid operations through MCP tools.

Use cases of Datomic MCP Server

Query Datomic databases from LLM-based chat interfaces
Enable AI coding assistants to inspect Datomic schema and data
Build agentic workflows that read and write Datomic data
Integrate Datomic with MCP-compatible development environments

FAQ from Datomic MCP Server

Does Datomic MCP Server support transact operations?

No, transact support is not implemented as the author is unsure it is a good idea.

How does the server handle database basis?

Each query currently runs (d/db conn) fresh, meaning a stable db basis is not yet implemented. As-of queries are planned but not supported.

What runtime does Datomic MCP Server require?

It requires Java to run the provided uberjar, and the DATOMIC_URI environment variable pointing to a valid Datomic database URI.

Is Datomic MCP Server free to use?

Yes, it is released under the MIT License and is free for commercial and non-commercial use.

What license does the underlying Modex framework use?

Datomic MCP Server is MIT-licensed, but Modex itself has a different license.
