create_proposal · Tron MCP: Risk & Policy

WHAT IT DOES

What create_proposal does on Tron

AI agents use create_proposal to create or update resources in Tron — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tron environment.

PARAMETERS

Parameter	Type	Required	Description
`network`	string	—	Network name. Defaults to mainnet.
`parameters`	object	Yes	Map of chain parameter key IDs (as string numbers) to proposed values. E.g. { '6': 100 } to propose changing parameter #6 to 100.

Parameters from the server's own tool schema.

WHY IT NEEDS A POLICY

Why create_proposal needs a policy

An AI agent can call create_proposal faster than any human can review — one bad instruction and it creates or modifies resources in Tron by the hundred, each call as confident as the last.

Verdict

create_proposal Rate-limited

create_proposal stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
