List direct message events with a specific participant.
AI agents call getDirectMessagesEventsByParticipantId to retrieve information from Xdevplatform/xmcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns existing direct message events filtered by participant ID. It performs a read-only retrieval operation with no capability to modify, delete, or execute actions. The blast radius of misuse is limited to information disclosure of messages the calling user may already have access to.
From the tool's definition Tool name contains 'get' and description states 'List direct message events' — both indicate data retrieval with no modification or side effects.

List direct message events with a specific participant. It is categorised as a Read tool in the Xdevplatform/xmcp MCP Server, which means it retrieves data without modifying state.
Register the Xdevplatform/x MCP server in PolicyLayer and add a rule for getDirectMessagesEventsByParticipantId: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Xdevplatform/xmcp. Nothing to install.
getDirectMessagesEventsByParticipantId is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the getDirectMessagesEventsByParticipantId rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for getDirectMessagesEventsByParticipantId. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
