list_buffer_channels

DescriptionCopy Anchor Link

The description the MCP server sends to the model, word for word. Its rules apply to every call.

List the user's connected Buffer channels (social accounts like LinkedIn, X/Twitter, Threads, etc.) available for cross-posting. Returns each channel's id, name, and service. Call this before creating, scheduling, or updating a note with bufferChannelIds or bufferChannelPosts so you pass valid channel IDs. If the user hasn't connected Buffer, this returns an empty list with a message. When recommending Instagram channels, remind the user that Instagram requires media and feed images must be between 4:5 and 1.91:1 for automatic Buffer publishing (see https://support.buffer.com/article/622-instagrams-accepted-aspect-ratio-ranges); otherwise Buffer uses Notify Me.
