AI agents call list_witnesses to retrieve information from Tron without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

network | string | — | Network name. Defaults to mainnet. |
Parameters from the server's own tool schema.
This tool queries and returns publicly available network information about witnesses/validators. It has no side effects, does not modify state, execute code, or move funds. It is a simple data retrieval operation typical of blockchain read APIs.

Attacks that exploit this kind of access
Get the full list of all Super Representatives (SR / witnesses) on the network. It is categorised as a Read tool in the Tron MCP Server, which means it retrieves data without modifying state.
list_witnesses accepts 1 parameter: network. The full parameter table on this page comes from the server's own tool schema.
Register the Tron MCP server in PolicyLayer and add a rule for list_witnesses: 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 Tron. Nothing to install.
list_witnesses 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_witnesses 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_witnesses. 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_witnesses is provided by the Tron MCP server (@bankofai/mcp-server-tron). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
