Fetch a single validator's registry entry by 32-byte hex address.
AI agents call get_validator_state 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 performs a data retrieval operation (fetch) from a registry. It queries and returns information about a validator's state/entry using their address as input. There is no indication of data creation, modification, deletion, code execution, or financial transactions.
From the tool's definition Tool name 'get_validator_state' and description 'Fetch a single validator's registry entry by 32-byte hex address' indicate a read-only query operation that retrieves data without side effects.
Attacks that exploit this kind of access
Fetch a single validator's registry entry by 32-byte hex address. 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 get_validator_state: 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.
get_validator_state 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_validator_state 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_validator_state. 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_validator_state 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.
get_validator_state 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.
