List registered tokens with optional VM type filter (evm, svm, daml).
AI agents call list_tokens 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 or queries information about registered tokens, optionally filtered by VM type. It performs no data creation, modification, deletion, code execution, or financial transactions. It is a straightforward read operation with minimal blast radius if misused by an AI agent, as it only exposes token metadata.
From the tool's definition Tool name 'list_tokens' and description 'List registered tokens with optional VM type filter' indicate a retrieval operation with no side effects. The verb 'list' is a classic read operation that queries data without modification.
Attacks that exploit this kind of access
List registered tokens with optional VM type filter (evm, svm, daml). 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 list_tokens: 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.
list_tokens 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 list_tokens 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 list_tokens. 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.
list_tokens 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.
