## MCP tools (5)

### `get_wallet_status` (~76 tokens)

Balances (USDT, CELO for gas, WBTC sats), remaining authorized budget (allowance) and the current DCA plan of a wallet. Free, read-only. ALWAYS call this before create_plan, renew_budget or cancel_plan.

Input parameters:

- `address` (string): Wallet to inspect (defaults to the configured treasury wallet)

### `get_portfolio` (~61 tokens)

Bitcoin accumulated by a wallet's plan: execution history (each purchase with tx hash and sats), cost basis, live BTC price. Free, read-only, via the CompraBTC API.

Input parameters:

- `address` (string): Wallet (defaults to the configured treasury wallet)

### `create_plan` (~210 tokens)

Create (or OVERWRITE) the treasury's Bitcoin DCA plan — signs 2 on-chain transactions: approve(total budget) + createPlan. Get explicit operator/human approval on the exact numbers first. Non-custodial: funds stay in the wallet; the verified contract enforces amount and interval; purchased WBTC arrives at this same wallet; fees ($0.005 + 1%) come OUT of each installment. First purchase executes within ~1 minute. amount_per_run: $0.10-$50 USDT (pool-depth safety cap). interval_seconds >= 3600 (hourly). budget = amount × installments, must be <= USDT balance.

Input parameters:

- `amount_per_run_usdt` (number, required): USDT per purchase (e.g. 1)
- `interval_seconds` (integer, required): Seconds between purchases (3600=hourly, 86400=daily)
- `total_budget_usdt` (number, required): Total USDT to authorize (allowance cap = installments × amount)

### `renew_budget` (~68 tokens)

Authorize a new total budget for the existing plan — signs one approve transaction. IMPORTANT: approve REPLACES the previous allowance (it does not add). Use when installments_left is low or purchases paused for exhausted budget.

Input parameters:

- `total_budget_usdt` (number, required): New total USDT to authorize

### `cancel_plan` (~75 tokens)

Stop the DCA plan immediately — signs cancelPlan() and, by default, also revokes the USDT allowance (approve 0) for a clean, double-locked exit. The WBTC already purchased stays in the wallet untouched.

Input parameters:

- `revoke_allowance` (boolean): Also set the allowance to 0 (default true)
