Context Cost

~2.0 KBTypical response size
Minimal attention impact (0.23% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

What it can do

Tool inventory

Tools (1)

🟢 Read-only🟡 Write🔴 Delete⚪ Unknown
🟢connection_reauthenticate(confirmed, client)

Use when a Winder call reports UNAUTHORIZED, invalid_token, or that the app connection requires reauthentication. First ask the user whether to reauthenticate; confirmed=false returns the question without opening OAuth. After explicit agreement call confirmed=true to request the client's OAuth linking UI and return reconnect links. This public tool returns guidance only, never user data or tokens. A client that blocks the app before sending requests may require reconnecting in its settings.
