### 2026-11-03 (score 50)

First indexed and scored.

## MCP tools (9)

### `blackpool_address` (~30 tokens)

Wallet address

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

### `blackpool_balance` (~120 tokens)

Balances

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).

Input parameters:

- `chain` (string): Chain, or "all". Default base.
- `pool` (string): Pool on that chain: eth|usdc (base, arbitrum), eth|usdg (robinhood), bnb|usdc|usdt (bsc). Default: the chain's stablecoin pool.
- `wait` (boolean)

### `blackpool_deposit` (~162 tokens)

Shield (deposit)

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.

Input parameters:

- `amount` (string, required): Decimal 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.
- `chain` (string): Chain. Default base.
- `pool` (string): Pool on that chain: eth|usdc (base, arbitrum), eth|usdg (robinhood), bnb|usdc|usdt (bsc). Default: the chain's stablecoin pool.

### `blackpool_send` (~199 tokens)

Private send

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.

Input parameters:

- `amount` (string, required): Decimal amount in token units, e.g. "10" or "0.25", or "max" for the whole private balance. Never wei.
- `chain` (string): Chain. Default base.
- `pool` (string): Pool on that chain: eth|usdc (base, arbitrum), eth|usdg (robinhood), bnb|usdc|usdt (bsc). Default: the chain's stablecoin pool.
- `recipient` (string, required)

### `blackpool_swap` (~151 tokens)

Private swap

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

Input parameters:

- `amount` (string, required): Decimal 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.
- `chain` (string): Chain. Default base.
- `from` (string, required): Pool to swap from (eth|usdc on base/arbitrum, eth|usdg on robinhood, bnb|usdt on bsc).
- `slippage_bps` (integer)

### `blackpool_bridge` (~181 tokens)

Private bridge

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.

Input parameters:

- `amount` (string, required): Decimal 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.
- `dest_asset` (string, required)
- `from` (string, required)
- `recipient` (string, required)
- `wait` (boolean): Poll delivery up to 6 minutes. Default false.

### `blackpool_bridges` (~38 tokens)

Bridge history

Every bridge of this account with status (PENDING_DEPOSIT, PROCESSING, SUCCESS, REFUNDED, FAILED) and refund address.

### `blackpool_assets` (~16 tokens)

Bridge assets

Bridge destination assets and valid origins.

### `blackpool_recover` (~51 tokens)

Recover

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

Input parameters:

- `chain` (string): Chain. Default base.
- `to` (string)

Blackpool is an MCP server listed in the public MCP registry as cash.blackpool/blackpool. Private payments for agents: shield, send, swap and bridge via ZK privacy pools on 4 EVM chains. This page covers its npm package (@blackpool/cli).

### Is the Blackpool MCP server safe to use?

Blackpool scores 66 out of 100 on VerifyMCP. We recorded 4 known advisories against it as of 5 November 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Blackpool MCP server expose?

Blackpool exposes 9 tools: blackpool_address, blackpool_balance, blackpool_deposit, blackpool_send, blackpool_swap, and 4 more. Their descriptions and schemas cost roughly 948 tokens of context every time the server is loaded.

### Is the Blackpool MCP server still maintained?

Blackpool is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Blackpool MCP server under?

Blackpool declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
