WHAT IT DOES

What UpdateOneMessageThread does on Twenty MCP Server

AI agents use UpdateOneMessageThread to create or update resources in Twenty MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Twenty MCP Server environment.

RISK

Why UpdateOneMessageThread is rated Medium

Updating a message thread is a reversible write operation that modifies existing CRM data without deleting it or causing external side effects. The severity is medium because unintended modifications to message threads in a CRM could impact communication history and team coordination, but the operation is reversible (data can be corrected).

From the tool's definition Tool name 'UpdateOneMessageThread' and description 'Update One messageThread' indicate modification of existing message thread data.

Attacks that exploit this kind of access

The rule that runs UpdateOneMessageThread safely

UpdateOneMessageThread Rate-limited

UpdateOneMessageThread stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
