AI agents call session to retrieve information from Kb without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Given the semantic context of a knowledge base server focused on storing and accessing notes, and the absence of explicit evidence of destructive, financial, or execute capabilities, 'session' most likely retrieves session context or state. Confidence is moderate (0.6) due to the empty description, which limits certainty.
From the tool's definition Tool name is 'session' on a knowledge base server that provides 'shared context and learning foundation' through 'note storage.' The server description emphasizes retrieval and access to persistent knowledge rather than modification.
Attacks that exploit this kind of access
session. It is categorised as a Read tool in the Kb MCP Server, which means it retrieves data without modifying state.
Register the Kb MCP server in PolicyLayer and add a rule for 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 Kb. Nothing to install.
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 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 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.
session is provided by the Kb MCP server (okash1n/kb). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
