View the full conversation history with another agent.
AI agents call agent.conversation to retrieve information from Sylex Memory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays existing conversation data without creating, modifying, deleting, or executing any operations. It is a read-only query of message history. The severity is low because while it accesses potentially sensitive conversation data, the blast radius of misuse is limited to information disclosure rather than system-wide damage or data loss.
From the tool's definition Tool name 'agent.conversation' and description 'View the full conversation history with another agent' indicate a retrieval operation with no modification or deletion capability.

View the full conversation history with another agent. It is categorised as a Read tool in the Sylex Memory MCP Server, which means it retrieves data without modifying state.
Register the Sylex Memory MCP server in PolicyLayer and add a rule for agent.conversation: 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 Sylex Memory. Nothing to install.
agent.conversation 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 agent.conversation 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 agent.conversation. 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.
agent.conversation is provided by the Sylex Memory MCP server (mastadoonprime/sylex-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
