MCP tools · 9 exposed · ~948 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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
blackpool_address ~30

Address of the agent wallet. Fund it with the asset to shield plus a little native gas for deposits.

Input schema present but exposes no named parameters.

No output schema declared.

blackpool_assets ~16

Bridge destination assets and valid origins.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

blackpool_balance ~120

Private (shielded) and public balances. With pool: one private pool only. wait=true polls up to 30 s while a private balance reads 0 (right after a deposit).

NameTypeReqDescription
chainstring–Chain, or "all". Default base.
poolstring–Pool on that chain: eth|usdc (base, arbitrum), eth|usdg (robinhood), bnb|usdc|usdt (bsc). Default: the chain's stablecoin pool.

No examples provided.

blackpool_bridge ~181

Private cross-chain transfer via NEAR Intents. from = origin private pool (base_eth, base_usdc, hood_eth, hood_usdg, arb_eth, arb_usdc, bsc_bnb, bsc_usdc, bsc_usdt); dest_asset from blackpool_assets; recipient is EVM 0x… or a Solana address for sol_*. Returns once submitted unless wait=true.

NameTypeReqDescription
amountstringyesDecimal amount in token units, e.g. "10" or "0.25", or "max" (send: the whole pool balance; swap/bridge: the most one operation can move). Never wei.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

blackpool_deposit ~162

Shield public funds from the agent wallet into the private pool. Signs and pays gas from the agent wallet. Takes 30-90 s. Do not retry after a timeout without checking blackpool_balance.

NameTypeReqDescription
amountstringyesDecimal amount in token units, e.g. "10" or "0.25", or "max" (send: the whole pool balance; swap/bridge: the most one operation can move). Never wei.

Sweep every registered burner that still holds funds back to the agent wallet (or to). Safe to run any time.

NameTypeReqDescription
chainstring–Chain. Default base.

blackpool_send ~199

Pay any EVM address privately from the private balance. The relayer pays gas; the recipient receives amount minus the fee (flat + 0.35%). amount "max" sends the whole balance of the pool (or of every pool when pool is omitted), splitting across several sends when needed and leaving dust untouched. Takes 30-90 s per send. Never retry after a timeout without checking blackpool_balance.

NameTypeReqDescription
amountstringyesDecimal amount in token units, e.g. "10" or "0.25", or "max" for the whole private balance. Never wei.

blackpool_swap ~151

Private same-chain swap between the native pool and the stablecoin pool; output is re-shielded. If it stops half-way, run blackpool_recover.
