linkedin_messages

Recall message on LinkedIn

Recall one of OUR OWN sent messages: it disappears for EVERY participant, not just for us. Addressed by the message sid, like react_linkedin_message. Irreversible - a wrong sid destroys a real conversation, so confirm the message first. LinkedIn allows a recall only WITHIN AN HOUR of sending; past that it refuses, so an older message comes back as 409 message_too_old_to_recall with nothing dispatched and no limit spent. The stored row is NOT removed: it stays in the thread marked is_deleted with an emptied body, which is what LinkedIn serves afterwards, so the operator still sees that something was withdrawn. Basic messenger only; an SN message, a non-2-… message_hash, or a row already marked is_deleted is refused before dispatch. Recallability is otherwise not pre-validated, so ‘not yours’ arrives as a wire error. Spends messaging_general, the reaction verbs’ bucket.

Contract:

MCP tool delete_linkedin_message_on_linkedin, registry package mcp.linkedin/linkedin_messages, mount linkedin.messaging.
Operation action, response envelope action.
Flags: dangerous: the MCP layer gates it behind a preview/commit token, and the effect cannot be undone through this API.
