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.
