GoTRON MCP Server

MCP server for TRON blockchain — let AI agents query balances, tokens, blocks, and build transactions.

Built on the GoTRON SDK and the Model Context Protocol.

Two Modes

	Local Mode	Hosted Mode
Transport	stdio	Streamable HTTP
Read tools	All	All
Transaction builders	All (unsigned tx hex)	All (unsigned tx hex)
Sign/Broadcast	Opt-in via --keystore	Disabled
Install	Required	Zero install

Claude Code

Add to current project:

claude mcp add gotron --scope project -- gotron-mcp --network mainnet

With keystore:

claude mcp add gotron --scope project -- gotron-mcp --network mainnet --keystore ~/.tronctl/keystore

Add globally:

claude mcp add gotron --scope user -- gotron-mcp --network mainnet

Hosted (zero install):

claude mcp add gotron --scope user --transport http https://mcp.gotron.sh/mcp

Sign & Broadcast (local mode + keystore)

Tool	Description
sign_transaction	Sign transaction using local keystore
broadcast_transaction	Broadcast signed transaction to network

Configuration

Flag	Env Var	Default	Description
--node	GOTRON_MCP_NODE	(per network)	TRON gRPC node address
--api-key	GOTRON_NODE_API_KEY	—	TronGrid API key
--network	GOTRON_MCP_NETWORK	mainnet	Network: mainnet, nile, shasta
--transport	—	stdio	Transport: stdio, http
--port	—	8080	HTTP server port
--bind	—	127.0.0.1	HTTP server bind address
--fallback-node	GOTRON_MCP_FALLBACK_NODE	—	Fallback gRPC node (auto-failover)
--keystore	—	—	Path to tronctl keystore directory
--tls	—	false	Use TLS for gRPC connection (default: plaintext)

Network Presets

Network	Default Node
mainnet	grpc.trongrid.io:50051
nile	grpc.nile.trongrid.io:50051
shasta	grpc.shasta.trongrid.io:50051

Explicit --node overrides network presets.

Security

• The server never stores or manages private keys directly
• All write tools return unsigned transaction hex — the user decides how to sign
• Keystore signing is opt-in via --keystore flag
• In hosted (HTTP) mode, all write and sign tools are automatically disabled
• API key is optional and only needed for TronGrid rate limits
