AI agents call contextualize to retrieve information from Pgmcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name 'contextualize' most likely indicates a Read operation—retrieving context or metadata for knowledge base items, which would be consistent with a knowledge base management system. However, confidence is moderate due to the empty description. Without additional context, the tool appears to query or retrieve information rather than modify, delete, or execute arbitrary operations.
From the tool's definition Tool name 'contextualize' suggests retrieving or processing context-related data. No description provided to confirm behavior.
Attacks that exploit this kind of access
contextualize. It is categorised as a Read tool in the Pgmcp MCP Server, which means it retrieves data without modifying state.
Register the Pg MCP server in PolicyLayer and add a rule for contextualize: 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 Pgmcp. Nothing to install.
contextualize 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 contextualize 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 contextualize. 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.
contextualize is provided by the Pg MCP server (veloper/pgmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
