MERX - TRON Resource Exchange

Execute a state-changing smart contract function. Estimates resources, buys via Merx if needed. Requires TRON_PRIVATE_KEY and TRON_ADDRESS.

Cancel an active monitor by its UUID. The monitor stops firing notifications. Auth required (API key).

Cancel a standing order by its UUID. The order is moved to CANCELLED status and will not trigger again. Already-executed actions are NOT reversed. Auth required (API key).

Check energy, bandwidth, and TRX balance for any TRON address. No auth required.

Side-by-side provider comparison with prices and availability. No auth required.

Convert a natural language energy management policy into MERX automation. Creates standing orders and monitors based on your instructions. Examples: - "Keep 500k energy on my wallet, buy when price is below 55 SUN, max 200 TRX/week" - "Buy energy every day at 6 AM UTC, 1 million units, for 24 hours" - "Alert me when my energy drops below 100k" Returns a preview of what will be created. Set apply=true to execute.

Convert TRON address between base58 (T...) and hex (41...) formats. No auth required.

Create a new Merx account, generate an API key, and get deposit info. No auth needed.

Create an invoice for another agent or human to pay. Returns payment URL, address, and QR code. Payment is detected automatically via ZeroMQ (<3 seconds).

Create a persistent server-side monitor that fires notifications when a condition is met. Four monitor types: delegation_expiry (warns when leased energy is about to expire so you can re-rent), balance_threshold (fires when an address goes below a TRX/USDT level), price_alert (fires when energy/bandwidth price crosses a SUN threshold), address_activity (fires on any incoming TX). Notification defaults to webhook=true if omitted. Auth required (API key).

Buy energy or bandwidth on Merx. Routed to cheapest provider. Auth required.

Create a zero-registration order via x402 pay-per-use. Requires TRON_PRIVATE_KEY.

Create a server-side standing order with trigger-based automation. Auth required.

Deposit TRX to your Merx account. Requires MERX_API_KEY + TRON_PRIVATE_KEY.

Configure automatic top-up when balance drops below a threshold. The configuration lives ONLY in the current MCP session — it is held in memory by the MCP server process and is lost on server restart, MCP client reconnect, or server redeploy. Top-ups are signed locally with TRON_PRIVATE_KEY and sent to your Merx deposit address (memo-routed). For persistent auto-deposit you currently need to call this tool again at the start of each session.

Declarative resource provisioning. Checks current resources on target address and purchases only what is missing. Auth required.

Estimate energy and bandwidth cost for a smart contract call. Compares rental vs burn cost. No auth required.

Estimate cost of a TRON transaction BEFORE sending. Aliases: estimate_cost, calculate_cost, transaction_cost, energy_cost, transfer_cost. Calculate exactly how much energy, bandwidth, and TRX a TRON transaction will cost before sending it. Use this to answer questions like "how much does a USDT transfer cost?" or "what will it cost me to send 100 USDT to address X?". Returns: energy units needed, bandwidth needed, TRX cost if you burn directly, and TRX cost if you rent energy from Merx (typically 70-80% cheaper). Supports trc20_transfer (e.g. USDT/USDC), trc20_approve, trx_transfer, and custom contract calls. No auth required.

Plan a multi-step operation (transfer, swap, buy resources, etc) and return a cost estimate, total energy/bandwidth needed, and the cheapest resource acquisition strategy. NOTE: actual on-chain execution of multi-step intents is not yet wired up — currently returns the same plan as simulate, regardless of dry_run. Use this for planning; for real execution call the underlying tools (create_order, transfer_trc20, execute_swap) yourself in sequence. Auth required.

Execute a token swap on SunSwap V2. Requires TRON_PRIVATE_KEY.

Explain a TRON or Merx concept in plain language. Hardcoded topics (exact match): energy, bandwidth, staking, delegation, sun_units, burn_vs_rent, merx_routing, provider_types. The lookup is fuzzy — substring matches also work, so "rent" finds "burn_vs_rent" and "providers" finds "provider_types". For topics outside this list (e.g. x402, stablecoins, gasfree), pick the closest hardcoded topic, or just answer the question yourself from the broader context — this tool only returns canned explanations of TRON resource economics.

Inspect any TRON address. Aliases: check_address, get_address_info, get_wallet_info, address_info, account_status. Read the full on-chain state of ANY TRON address (does not have to be your own): TRX balance, free + delegated energy, free + delegated bandwidth, frozen TRX, account creation timestamp. Use this to check if an address has enough resources before sending a transaction, or to inspect any TRON wallet. No auth required, no API key needed.

Get your Merx account balance (TRX, USDT, locked). Requires MERX_API_KEY.

Quick lookup of the single cheapest provider for a resource type, with optional minimum amount filter. CAVEAT: this returns a single representative price per provider, not broken down by duration tier — short rentals (5min) and long rentals (30 days) have very different per-unit prices and this tool does not distinguish between them. For an accurate per-tier comparison, use get_prices(duration=N) where N is the exact rental duration in seconds (e.g. 3600 for 1h, 86400 for 1d, 2592000 for 30d). Use get_best_price only when you need the absolute floor price as a quick sanity-check. No auth required.

Get TRON block info by number (or latest if omitted). No auth required.

Get TRON network parameters (energy fee, bandwidth cost, etc.) with Merx price comparison. No auth required.

Get on-chain metadata for a TRON smart contract: existence check, owner address, energy origin, code hash, contract name (if set), ABI entries count. Use this to check whether an address is a contract before calling read_contract or estimate_contract_call. For TRC20-specific metadata (name, symbol, decimals, totalSupply) use get_token_info instead. No auth required.

Get your Merx deposit address and memo. Requires MERX_API_KEY.

Get order status by UUID. Aliases: get_order_status, check_order, order_status, order_details, fetch_order. Check the status and fill details of an existing order by its UUID. Returns current status (PENDING/FILLING/FILLED/PARTIAL/FAILED/CANCELLED), fill amounts, provider used, on-chain delegation tx hash if delivered. Use this to poll order progress after creating an order. Auth required (API key).

Historical price snapshots. No auth required.

Get current energy and bandwidth prices from all Merx providers, sorted by best (minimum) price across all duration tiers. Each provider lists ALL its duration tiers (5min/1h/1d/7d/30d etc) — short rentals are usually more expensive per unit than long ones, so always check tier-by-tier. Optionally filter by exact duration in seconds. No auth required.

Get full details of a single standing order by its UUID. Returns trigger config, action params, budget, executions count, and status. Auth required (API key).

Get a real swap quote from SunSwap V2. No auth required.

Get TRC-20 token metadata: name, symbol, decimals, total supply. No auth required.

Get token price via SunSwap quote + CoinGecko USD rate. No auth required.

Look up a transaction by ID on TRON. No auth required.

Get your Merx account transaction history. Requires MERX_API_KEY.

Get TRC-20 token balance for an address. Supports symbol (USDT, USDC) or contract address. No auth required.

Quick TRX balance for a TRON address. No auth required.

Get current TRX price from CoinGecko. No auth required.

List all monitors you created with create_monitor, optionally filtered by status (ACTIVE/CANCELLED). Each row shows the full monitor UUID (pass to cancel_monitor), monitor type, target address, and status. Note: the Target column will be empty for monitor types that do not have a single watched address — specifically price_alert and balance_threshold (when watching the API key holder rather than a third-party address). For delegation_expiry and address_activity monitors, Target will always be set. Auth required (API key).

List recent orders with optional status filter. Auth required.

List all Merx providers with types, durations, and availability. No authentication required.

List all standing orders with optional status filter. Auth required.

Log in to an existing Merx account. No MERX_API_KEY needed.

Look up a MERX invoice. Shows amount, recipient, token, and status. Agent must sign and broadcast the transfer separately (non-custodial).

Pay an x402 invoice by signing and broadcasting a TRX transfer to the invoice address, then verifying the payment with the facilitator. x402 (Coinbase + Cloudflare HTTP 402 standard) is the protocol AI agents use to pay APIs per call. Use this when you receive an invoice_id from a paywalled service or another agent. REQUIRES: TRON_PRIVATE_KEY in env (use set_private_key first) AND a valid invoice_id from create_invoice or x402 challenge response. The transfer is signed locally — your private key never leaves the MCP process.

Call a view/pure function on a TRON smart contract. No auth or private key required.

Register your TRON address as an agent on agent.merx.exchange. Required ONCE before using request_payment, create_invoice, watch_address, agent_status, or any other agent payment tool. Pass the TRON address you want to use as the on-chain identity for this API key. Idempotent — calling twice with the same key returns the existing registration. Auth required (API key).

Create a TRC20 payment request on TRON (USDT, USDC, USDD, or any TRC20). Returns a payment address. Fires webhook when payment arrives (<3 seconds). Use for receiving payments from other agents or humans. Requires agent registration first — call register_agent if you get AGENT_NOT_REGISTERED error.

Broadcast a signed TRON transaction with automatic energy optimization. If the target address lacks sufficient energy, MERX purchases the deficit at the best market price before broadcasting. One call: estimate, buy energy, wait for delegation, broadcast. Requires MERX_API_KEY with the "broadcast" scope, and a pre-signed transaction. Returns txid on success, refunds on timeout. NOTE: This endpoint is currently behind a feature flag and disabled by default in production. If you get a 503 MAINTENANCE error, use the manual flow instead: call ensure_resources to provision energy, then sign and broadcast the transaction with your own TronWeb client.

Get on-chain transaction history for a TRON address. No auth required.

Set your Merx API key for this session. Unlocks all authenticated tools (trading, balance, orders). Use this if you already have an API key.

Set your TRON private key for this session. Address is derived automatically. Enables write tools: transfer_trx, transfer_trc20, approve_trc20, execute_swap, deposit_trx. Key stays local - never sent to Merx servers.

Dry-run a multi-step operation (transfer, swap, buy resources, etc) without sending anything on-chain. Returns per-step energy and bandwidth estimates plus a total TRX cost. Use this to preview a plan before committing — for example, before transferring USDT to multiple recipients you can simulate to see the total energy cost. No auth required.

Recommend a rental duration based on your use case. No authentication required.

Transfer TRC-20 tokens with automatic energy optimization. Signs and broadcasts on-chain. Requires TRON_PRIVATE_KEY.

Send TRX to an address. Checks bandwidth, buys via Merx if needed. Signs and broadcasts on-chain. Requires TRON_PRIVATE_KEY.

Validate a TRON address format and check on-chain status. No auth required.

Block until an order reaches a terminal state (FILLED, PARTIAL, FAILED, or CANCELLED) by polling get_order at fixed intervals. Use this right after create_order when you need to confirm the energy/bandwidth has actually been delegated on-chain before sending the next transaction. Returns the final order details including the on-chain delegation tx hash. Auth required.

Watch any TRON address for TRC20 transfers (USDT, USDC, USDD, or any token). Fires webhook on each matching transfer. Persistent - runs 24/7 even when conversation ends.

Withdraw TRX or USDT from your Merx account to an external TRON address. The "amount" parameter is interpreted in the currency specified by "currency" — i.e. for currency=TRX it is TRX units, for currency=USDT it is USDT units. (The legacy parameter "amount_trx" is still accepted as an alias for backwards compatibility, but is misleading when currency is USDT — prefer "amount" in new code.) Requires MERX_API_KEY.
