## MCP tools (5)

### `getoffers` (~176 tokens)

Get all open offers for a specific currency or identity. Returns both buy and sell offers — offers of the asset and offers for the asset. Use iscurrency to switch between currency offers and identity offers. Response keys are dynamic and generated by the daemon based on the queried asset — parse them dynamically. Use this to discover what's available on the market before making or taking offers.

Input parameters:

- `chain` (string, required): Chain to query (e.g., "VRSC", "vrsctest")
- `currencyorid` (string, required): Currency name/i-address or identity name/i-address to check for offers
- `iscurrency` (boolean): If true, look for currency offers. If false (default), look for identity offers.
- `withtx` (boolean): If true, include serialized hex of the exchange transaction for signing. Default: false.

### `listopenoffers` (~113 tokens)

List open offers from the current wallet. Shows what this wallet has offered on-chain. Can filter by expired/unexpired status. Use this to check the status of offers the agent has created, or to find offers that need to be closed.

Input parameters:

- `chain` (string, required): Chain to query (e.g., "VRSC", "vrsctest")
- `expired` (boolean): Include expired offers. Default: true.
- `unexpired` (boolean): Include unexpired (active) offers. Default: true.

### `makeoffer` (~426 tokens)

Create a new on-chain atomic swap offer. Offers are fully decentralized — no intermediary, no escrow. The offer transaction locks the offered asset on-chain until the offer is taken, expires, or is closed. Supports currency-for-currency, currency-for-identity, identity-for-currency, and identity-for-identity swaps. For currency offers, use {"currency": "name", "amount": n}. For identity offers (without control tokens), use {"identity": "name@"} or a full identity definition. If an identity has a control token (flags: 5), offer/request the control token as a currency instead: {"currency": "idname.parent", "amount": 0.00000001}. Always include parent in identity definitions.

Input parameters:

- `chain` (string, required): Chain to transact on (e.g., "VRSC", "vrsctest")
- `changeaddress` (string, required): Transparent address or VerusID ("ID@") for change.
- `expiryheight` (number): Block height at which this offer expires. Default: current height + 20 (~20 minutes). Set higher for marketplace listings.
- `feeamount` (number): Custom fee amount. Default: 0.0001.
- `for` (object, required): What to accept in return — {"currency": "name", "amount": n, "address": "dest"} for currency (address is REQUIRED — can be R-address, VerusID name@, or i-address), or full identity definition (with p…
- `fromaddress` (string, required): Source address for funds. If the user has not specified a preferred address, ask which address to use or if they prefer a wildcard ("*", "R*", "i*", or "z*" for private txs).
- `offer` (object, required): What to offer — {"currency": "name", "amount": n} for currency, or {"identity": "name@"} / full identity definition for identity.
- `returntx` (boolean): If true, return signed transaction hex instead of broadcasting. Default: false.

### `takeoffer` (~407 tokens)

Accept an existing on-chain offer. Creates and posts a transaction that atomically executes the exchange — both sides swap in a single transaction, or neither does. The offer transaction must have at least 1 confirmation before it can be taken. Before taking, verify the offer hasn't expired by checking blockexpiry against current block height. deliver is what you give, accept is what you get. For currency: deliver {"currency": "name", "amount": n}, accept {"address": "addr", "currency": "name", "amount": n}. For identity: deliver "name@" (string), accept is full identity definition with parent. If the identity has a control token, use control token currency instead.

Input parameters:

- `accept` (object, required): What the taker receives — {"address": "addr", "currency": "name", "amount": n} (currency) or full identity definition (identity).
- `chain` (string, required): Chain to transact on (e.g., "VRSC", "vrsctest")
- `changeaddress` (string, required): Transparent address or VerusID for change.
- `deliver` (required): What the taker delivers — "name@" (identity) or {"currency": "name", "amount": n} (currency).
- `feeamount` (number): Custom fee amount. Default: 0.0001.
- `fromaddress` (string, required): Source address for funds. If the user has not specified a preferred address, ask which address to use or if they prefer a wildcard ("*", "R*", "i*", or "z*" for private txs).
- `returntx` (boolean): If true, return signed transaction hex instead of broadcasting. Default: false.
- `tx` (string): Hex transaction to complete (from makeoffer with returntx=true). Either txid or tx is required.
- `txid` (string): Transaction ID of the offer to accept (from getoffers or makeoffer). Either txid or tx is required.

### `closeoffers` (~156 tokens)

Close (cancel) open offers and reclaim the locked funds. Returns null on success. Always closes expired offers automatically, even if no parameters are given. When specific offer txids are provided, closes only those offers. Use this to cancel offers that are no longer wanted, or as periodic cleanup to reclaim funds from expired offers.

Input parameters:

- `chain` (string, required): Chain to transact on (e.g., "VRSC", "vrsctest")
- `destination` (string): Transparent or private address to send reclaimed funds to.
- `privatefundsdestination` (string): Private (Sapling) address for native funds only.
- `txids` (array): Array of offer transaction IDs to close. If omitted, closes all expired offers.
