AI agents call title_chain to retrieve information from CorteX402 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Title chain retrieval is consistent with querying property title history or blockchain transaction records—a read operation with no side effects. The server explicitly handles financial settlement (USDC payments) separately via on-chain receipts, isolating payments from data access.
From the tool's definition Tool name 'title_chain' combined with server context listing 'title chain' alongside data products like 'property dossier', 'wallet balance', and 'sanctions screening'. The pattern and naming convention suggest a read-only data retrieval function.
Attacks that exploit this kind of access
title_chain. It is categorised as a Read tool in the CorteX402 MCP Server, which means it retrieves data without modifying state.
Register the CorteX402 MCP server in PolicyLayer and add a rule for title_chain: 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 CorteX402. Nothing to install.
title_chain 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 title_chain 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 title_chain. 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.
title_chain is provided by the CorteX402 MCP server (ooak21/cortex402-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
