Read recent messages from a specific conversation
AI agents call read_messages to retrieve information from Beeper MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves message data without creating, modifying, deleting, or executing any operations. It is a straightforward read operation on local message history with no side effects. The read-only design and local-only operation further support the low severity classification, as the blast radius is limited to information disclosure of the user's own message history.
From the tool's definition Tool name is 'read_messages' and description states 'Read recent messages from a specific conversation'. Server description emphasizes 'read-only access' and 'local Beeper message history', with no modification or deletion capabilities mentioned.
