Workflow: SR & Voting Queries

User: "Who are the top SRs? What are the chain parameters?"

1. 1. tronscan-sr-governance — getWitnessList → SR/partner/candidate list; optionally filter by type.
2. tronscan-sr-governance — getWitnessGeneralInfo → total votes, block stats, witness count.
3. For chain config (fees, energy/bandwidth price): getChainParameters.

User: "Which SRs did this address vote for?"

1. 1. tronscan-sr-governance — getAccountVotes with address → vote targets and amounts.

User: "What is the vote/ranking history of SR X?"

1. 1. tronscan-sr-governance — getWitnessVoteInfo with witness address → vote metrics and history.

User: "Who voted for SR X?" or "List voters of SR X"

1. 1. tronscan-account-profiler — getVoteList (Account API) with SR address → voter list.

Troubleshooting

• - MCP connection failed: If you see "Connection refused", verify TronScan MCP is connected in Settings > Extensions.
• API rate limit / 429: TronScan API has call count and frequency limits when no API key is used. If you encounter rate limiting or 429 errors, go to TronScan Developer API to apply for an API key, then add it to your MCP configuration and retry.

Invalid witness address

Ensure the address is a valid TRON base58 format (starts with T). For voter list of an SR, use getVoteList (Account API) with the SR address.
