MCP tools · 20 exposed · ~2,802 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens
bridge_chains ~86

List supported chains for cross-chain bridging. Shows which providers support each chain. Chains are deduplicated and grouped by ecosystem: EVM, Cosmos, and Solana. Use 'search' parameter to filter by chain name. Use this to discover available routes before calling bridge_get_quote.

NameTypeReqDescription
searchstringFilter chains by name (e.g. 'base', 'arb')

No output schema declared.

No examples provided.

bridge_execute ~229

Get the unsigned transaction data to execute a cross-chain bridge transfer. Supports all providers: LI.FI, Squid Router, deBridge, Across, Relay, Persistence Interop. By default returns unsigned transaction(s) for the agent/user to sign and send. Set sign_and_send=true to sign and broadcast using the locally-stored wallet key (requires wallet_setup). Preconditions: Call bridge_get_quote first and pass the quoteId. Ensure sufficient gas on source chain. If an approval is needed (unsigned mode), send the approvalTransaction first, then the main transaction. After execution, use bridge_status with the returned trackingId to monitor progress.

NameTypeReqDescription
quoteIdstringyesQuote ID from bridge_get_quote result
sign_and_sendbooleanIf true, sign and broadcast the transaction server-side using the wallet key from wallet_setup. Supports EVM chains and Persistence Interop. Solana falls back to unsigned.
slippagenumberMax slippage tolerance (0.005 = 0.5%). Applied by backends during quoting; reserved for future per-execution override.

No output schema declared.

No examples provided.

bridge_get_quote ~404

Get the best cross-chain bridge quote across multiple providers (LI.FI, Squid Router, deBridge, Across, Relay, Persistence Interop). Supports EVM chains, Cosmos chains (Persistence, Cosmos Hub), and Solana. Accepts token symbols (e.g. 'USDC', 'ETH', 'WBTC', 'XPRT', 'ATOM') or contract addresses (0x...). Symbols are resolved to verified canonical addresses only — no unverified tokens. Returns ranked options by output amount, speed, and fees. Includes failedProviders array showing which providers didn't return quotes and why. Preconditions: None for quoting. Use bridge_execute to act on a quote. Error codes: 'Token resolution failed' (unknown symbol), 'Rate limited' (too many requests), 'Validation error' (invalid params).

NameTypeReqDescription
amountstringyesAmount in human-readable units (e.g. '100' for 100 USDC)

toAddressstringRecipient address (defaults to fromAddress)
toChainstringyesDestination chain
toTokenstringyesToken to receive — symbol (e.g. 'USDC', 'ETH') or contract address (0x...). Symbols resolve to verified canonical addresses only.

No output schema declared.

No examples provided.

bridge_quote_multi ~250

Get quotes for multi-hop routes across supported EVM chains. Resolves optimal path internally -- e.g., ETH on Base to USDC on Arbitrum may route through WBTC. Returns the full route as ordered hops with per-hop detail. Note: For Cosmos destinations (Persistence, Cosmos Hub), use xprt_farm_boost or bridge_get_quote with Squid Router.

toTokenstringyesToken to receive -- symbol (e.g. 'USDC', 'ETH') or contract address (0x...)

No output schema declared.

No examples provided.

bridge_status ~168

Check the status of a cross-chain bridge transfer. Supports all providers: LI.FI, Squid Router, deBridge, Across, Relay, Persistence Interop. Provide the tracking ID from bridge_execute, or a transaction hash with provider name. Returns: status (pending/in_progress/completed/failed), source/destination tx hashes, elapsed time, and estimated remaining time.

NameTypeReqDescription

searchstringFilter by token name or symbol

No output schema declared.

No examples provided.

bridgekitty_help ~73

Uses multiple RPCs with automatic failover. Returns per-token balance, USD value (via CoinGecko), and total portfolio value. Call this before any bridging or farming operation to verify sufficient funds and gas.
