Get the CAIP-2 chain id for this node:
AI agents call caip2 to retrieve information from Tenzro Ledger MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns a chain identifier (CAIP-2 format) from the current node. It is a read-only query operation with no capability to modify, delete, execute code, or move funds. The blast radius of misuse is minimal—an agent could only obtain chain identification information, which is typically non-sensitive metadata.
From the tool's definition Tool name and description: 'Get the CAIP-2 chain id for this node' — a pure retrieval operation that queries and returns a chain identifier with no side effects or state modifications.
Attacks that exploit this kind of access
Get the CAIP-2 chain id for this node:. It is categorised as a Read tool in the Tenzro Ledger MCP MCP Server, which means it retrieves data without modifying state.
Register the Tenzro Ledger MCP server in PolicyLayer and add a rule for caip2: 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 Tenzro Ledger MCP. Nothing to install.
caip2 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 caip2 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 caip2. 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.
caip2 is provided by the Tenzro Ledger MCP server (https://canton-mcp.tenzro.network/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
caip2 is one line of Tenzro Ledger's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
