This server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

Tools (11)

build_approveBuild an ERC-20 `approve(spender, amount)` tx — e.g. the NFPM before `build_mint`/`build_increase`, or Permit2 before a Permit2-paid `build_swap`. `amount: "max"` for an unlimited allowance.

Parameters not published.

build_closeRemove all liquidity **+** collect; `burn: true` also burns the empty NFT. Returns the read position.

Parameters not published.

build_collectCollect all uncollected fees from a position to `recipient`.

Parameters not published.

build_increaseAdd liquidity to an existing position.

Parameters not published.

build_mintMint a new position (raw ticks + wei amounts).

Parameters not published.

build_swapExact-in single-hop `tokenIn` → `tokenOut` swap via the Universal Router; with `wrapWei` (tokenIn = WETH9) it wraps native ETH first and sweeps the remainder, with `unwrapOut` (tokenOut = WETH9) it unwraps the output to native ETH — in the same tx either way. Pass `sender` and the default Permit2 payment path auto-detects an insufficient allowance, returning a signed-permit request instead of a tx — no separate on-chain Permit2 approval needed.

Parameters not published.

build_wrapWrap native ETH → WETH via the Universal Router (`WRAP_ETH`).

Parameters not published.

get_pool_state**Read-only.** Live pool state (tick, sqrtPriceX96, human price, spacing); optional ±pct range suggestion (rounded inward) and live-ratio `amount0Desired`/`amount1Desired` from wallet balances.

Parameters not published.

get_positions**Read-only.** List every position NFT a wallet holds (token0/1, fee, tick range, liquidity, tokens owed) via the NFPM's ERC-721 enumeration.

Parameters not published.

get_swap_quote**Read-only.** Quote an exact-in single-hop swap via Uniswap v3 QuoterV2 — the live `amountOut` a `build_swap` with the same params would get, plus `amountOutMin` (after `slippageBps`) ready to feed straight into `build_swap`.

Parameters not published.

plan_position**Read-only.** Turn a human price range + human amounts into aligned ticks + wei amounts for `build_mint`. Reads token decimals over RPC.

Parameters not published.
