Why MCP

Your data, your client

Some people prefer Claude Desktop. Others live in ChatGPT. Some are building their own tools.

MCP—the Model Context Protocol—is an open standard for connecting AI assistants to external data. Achriom implements it so you can access your library from wherever you work.

Tradeoffs

Raw tools vs. tuned experience

The in-app librarian knows things external clients don't—your conversation history, current research focus, how to present results visually. It's built for the experience.

External clients get the raw tools. Capable, but less context. Use the app when you want the full experience. Use MCP when you want your data somewhere else.

Available on Pro

MCP access requires a Pro subscription. Generate your API key in account settings.
