geml

MCP serverFiles & storage

Your AI can edit Markdown and GEML files section by section, and any write that would produce a bad file is refused, so a mistaken edit can't leave a document broken. geml works one section in and one section out, keeping each change focused on a single part of the file. Once added, your AI can read and update sections of your documents with that check built in.

Install geml

The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.
