37 tools, verified live

Pulled straight from the server with tools/list on 2026-10-17.

stocktoken_access_pricing

List Free / Pro / Team pricing (ETH on-chain, no Stripe) and how agents pay for write tools.

stocktoken_access_checkout

Build on-chain ETH payment plan for Pro/Team. After user pays, call stocktoken_access_activate.

stocktoken_access_activate

After ETH payment to treasury is confirmed, verify and issue API key (shown once).

stocktoken_access_status

Check paid access for current API key context or a wallet owner.

stocktoken_listread-only

List canonical Stock Tokens, ETFs, USDG, and WETH on Robinhood Chain 4663. Use this before trusting any address. Do NOT use for US brokerage equities (use Robinhood Trading MCP). Only registry addresses are real tokenized stocks.

stocktoken_get

Get metadata for one canonical Stock Token or core asset by symbol (e.g. NVDA) or contract address on Robinhood Chain 4663. Use to verify a token is official before trading.

stocktoken_priceread-only

Read the Chainlink USD price and ERC-8056 uiMultiplier for one registry token on chain 4663. This is not a swap quote and not a brokerage quote. Use stocktoken_quote when you need amountOut.

stocktoken_value_holdings

Read balances. This does not quote or swap. For a trade, use stocktoken_quote then stocktoken_execute_plan.

stocktoken_policy_get

Get current AI Agent Tokenized Stock OS agent policy (max notional, slippage, simulate-first, kill switch).

stocktoken_policy_set

Update session policy guardrails for AI Agent Tokenized Stock OS.

stocktoken_quoteread-only

Quote a Stock Token swap on chain 4663. Compares 0x, the Uniswap API, on-chain Uniswap v3, and hookless Uniswap v4, and returns the executable route with the higher amountOut. If none is executable, the result is oracle-indicative and is not a fill. Pro required. Does not sign or broadcast.

stocktoken_simulateread-only

Pre-trade check on chain 4663: allowlist, policy limits, and whether the quote is executable. This is not an eth_call of the swap. Pro required. If executable is false, stop and do not promise a fill.

stocktoken_execute_plan

Build an unsigned swap plan on chain 4663. Picks the executable venue with the higher amountOut (v4, v3, 0x, or Uniswap API). Steps are an ETH fee of about 10 bps, token approve, and the swap. v4 also adds a Permit2 approval. Does NOT sign or broadcast. Pro required. The user signs. A v4 plan expires 30 minutes after it is built.

stocktoken_session_create

Create a durable agent session with scoped permissions (persisted to DATA_DIR). Non-custodial.

stocktoken_session_kill

stocktoken_tip_assets

What the AATOS tip wallet can accept: native ETH + any ERC-20 on Robinhood Chain 4663; optional native BTC address if configured.

Optional Permit2 helper. stocktoken_execute_plan already includes the Permit2 approval on a v4 route. Use this only when you are assembling a plan by hand.

stocktoken_liquidity_matrix

Liquidity matrix for major USDG pairs on chain 4663. each row reports hookless Uniswap v4 and on-chain v3. eitherExecutable true means at least one of those can fill the sample size. A false row is not every pool on earth: hooked v4 pools are not scanned. If stocktoken_quote.executable is false, do not promise a fill.

stocktoken_find_pools

Scan Uniswap v3 pool addresses only. This is not a fill check and it does not see v4. For a swap, use stocktoken_quote then stocktoken_execute_plan.

stocktoken_system_status

Full system status: secrets, venues, chain, version, session count, fees.

stocktoken_explain_routing

Start here. Brokerage equities go to Robinhood Trading MCP. Stock Tokens on chain 4663 stay here: stocktoken_list, stocktoken_price, stocktoken_quote, stocktoken_execute_plan.
