  inputSchema.properties.guestSession.description: "Restricted guest credential returned by start_story. Retain private..."
  What this check looks for
Description, as the server wrote it
Send the user’s chosen action or dialogue to Teasa inference. Replies automatically use the language saved by start_story; no language parameter is needed on later turns. Pass the guestSession from start_story unless connected with OAuth. Uses their guest or signed-in Teasa allowance. Reuse clientMessageId and identical input on retries. Never invent or submit a user action without their instruction. A pending turn must be polled with get_turn; do not send another message to finish it.

Start a saved Teasa conversation for a story selected by the user. Explicitly supply the selected translation language; this controls the opening and every model reply even when the original story has another source language. No browser authorization or signup required: without OAuth or guestSession, creates a free guest and returns guestSession. Retain it privately; pass it on ALL subsequent tools, retries and pages. Guest access lasts 24 hours. Reuse requestId with guestSession for retries; if cards.nextPage is present, repeat start_story with the same requestId, language and that page. Returns the opening, branchId and branchVersion. No inference is charged for the opening.

Anlyon alternative

7 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
