Tools

• agent_status

  Get a snapshot of your agent payment service: registered TRON address, count of pending payment requests (request_payment), active address watches (watch_address), and outstanding invoices (create_invoice). Use this right after register_agent to confirm the agent is set up, or any time you want to see how much in-flight activity your agent has. Auth required (API key) and agent must be registered first via register_agent.

  shallow
• analyze_prices

  Market price analysis with trends and recommendations. No auth required.

  shallow
• approve_trc20

  Approve TRC-20 spending allowance. Signs and broadcasts on-chain. Requires TRON_PRIVATE_KEY.

  shallow
• calculate_savings

  Calculate savings from renting energy vs burning TRX. No authentication required.

  shallow
• call_contract

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

  shallow
• cancel_monitor

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

  shallow
• cancel_standing_order

  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).

  shallow
• check_address_resources

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

  shallow
• compare_providers

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

  shallow
• compile_policy

  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.

  shallow
• convert_address

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

  shallow
• create_account

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

  shallow
• create_invoice

  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).

  shallow
• create_monitor

  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).

  shallow
• create_order

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

  shallow
• create_paid_order

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

  shallow
• create_standing_order

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

  shallow
• deposit_trx

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

  shallow
• enable_auto_deposit

  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.

  shallow
• ensure_resources

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

  shallow
• estimate_contract_call

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

  shallow
• estimate_transaction_cost

  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.

  shallow
• execute_intent

  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.

  shallow
• execute_swap

  Execute a token swap on SunSwap V2. Requires TRON_PRIVATE_KEY.

  shallow
• explain_concept

  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.

  shallow
• get_account_info

  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.

  shallow
• get_balance

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

  shallow
• get_best_price

  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.

  shallow
• get_block

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

  shallow
• get_chain_parameters

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

  shallow
• get_contract_info

  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.

  shallow
• get_deposit_info

  Get your Merx deposit address and memo. Requires MERX_API_KEY.

  shallow
• get_order

  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).

  shallow
• get_price_history

  Historical price snapshots. No auth required.

  shallow
• get_prices

  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.

  shallow
• get_standing_order

  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).

  shallow
• get_swap_quote

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

  shallow
• get_token_info

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

  shallow
• get_token_price

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

  shallow
• get_transaction

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

  shallow
• get_transaction_history

  Get your Merx account transaction history. Requires MERX_API_KEY.

  shallow
• get_trc20_balance

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

  shallow
• get_trx_balance

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

  shallow
• get_trx_price

  Get current TRX price from CoinGecko. No auth required.

  shallow
• list_monitors

  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).

  shallow
• list_orders

  List recent orders with optional status filter. Auth required.

  shallow
• list_providers

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

  shallow
• list_standing_orders

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

  shallow
• login

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

  shallow
• lookup_invoice

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

  shallow
• pay_invoice

  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.

  shallow
• read_contract

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

  shallow
• register_agent

  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).

  shallow
• request_payment

  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.

  shallow
• resource_broadcast

  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.

  shallow
• search_transaction_history

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

  shallow
• set_api_key

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

  shallow
• set_private_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.

  shallow
• simulate

  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.

  shallow
• suggest_duration

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

  shallow
• transfer_trc20

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

  shallow
• transfer_trx

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

  shallow
• validate_address

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

  shallow
• wait_for_delegation

  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.

  shallow
• watch_address

  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.

  shallow
• withdraw

  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.
