Retrieves all registered agent coordination sessions ordered by last active time.
AI agents call get_active_sessions to retrieve information from Pg Mnemosyne without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a read-only retrieval of session metadata ordered by activity timestamp. It queries the coordination hub to list active sessions but does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal—an AI agent retrieving session information cannot cause financial harm, data loss, or unintended executions. This is a straightforward Read operation.
From the tool's definition Tool name 'get_records' pattern and description 'Retrieves all registered agent coordination sessions' indicates data retrieval with no modification. This is a query operation that fetches session information without side effects.
Attacks that exploit this kind of access
Retrieves all registered agent coordination sessions ordered by last active time. It is categorised as a Read tool in the Pg Mnemosyne MCP Server, which means it retrieves data without modifying state.
Register the Pg Mnemosyne MCP server in PolicyLayer and add a rule for get_active_sessions: 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 Pg Mnemosyne. Nothing to install.
get_active_sessions 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 get_active_sessions 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 get_active_sessions. 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.
get_active_sessions is provided by the Pg Mnemosyne MCP server (janadasroor/pg-mnemosyne-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
