MCP troubleshooting

Athanor's tools do not show up

Check that the connector is turned on for the chat you are in, then start a new chat. Most chat apps turn connectors on per chat. In a terminal client, restart it after you change its configuration file.

Gemini CLI does not list athanor

Gemini CLI loads MCP servers only in a folder you trust. Start gemini in the folder and accept the trust prompt, or run /trust, then run /mcp to check. See Gemini CLI.

ChatGPT has no Create button under Apps & Connectors

Developer mode is off, or your plan does not include it. Turn it on under Settings > Apps & Connectors > Advanced settings. See ChatGPT.

"Too many requests"

The server allows 60 calls a minute from one address. Wait a minute and try again.

A structure is refused

Inputs over 20,000 characters are refused, and so are structures the safety screen will not handle as a synthesis target. The reply says which.

"No document … it expired"

A document made with document_create is a working copy. It is deleted two hours after its last use, so a handle from an old conversation no longer works. Ask the assistant to start again with document_create, or to recreate it from the .athanor file it exported. To keep a document, have the assistant call document_export with the format athanor and open the file in Athanor.

"The document is over 2 MB"

A working copy on the server can hold up to 2 MB. Export what you have and continue in the Athanor app, which has no such limit.

My client is not listed

Any client that supports remote MCP servers over Streamable HTTP can connect to https://mcp-athanor.arbastro.com/mcp. Use the configuration of the listed client closest to yours.
