get_session
AI agents call get_session to retrieve information from MCP AI Agent Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name 'get_' prefix strongly indicates a retrieval operation with no side effects. Despite the empty description reducing confidence slightly, the naming convention and position within a session management suite (where 'clear_session' handles deletion and 'send_message' handles writes) indicates this reads session data.
From the tool's definition Tool named 'get_session' with empty description; contextually part of session management functionality alongside 'clear_session' and 'send_message', suggesting it retrieves session state rather than modifying it.
Attacks that exploit this kind of access
get_session. It is categorised as a Read tool in the MCP AI Agent Server MCP Server, which means it retrieves data without modifying state.
Register the MCP AI Agent Server MCP server in PolicyLayer and add a rule for get_session: 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 MCP AI Agent Server. Nothing to install.
get_session 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_session 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_session. 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_session is provided by the MCP AI Agent Server MCP server (singularitybridge/mcp-ai-agent-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
