First indexed and scored.

## MCP tools (79)

### `uxc_get_agent` (~49 tokens)

Show the agent account snapshot: activation state, non-withdrawable credit balance (USD), configured per-asset receive wallets, webhook URL, and an earnings summary (settlements count + total earned).

### `uxc_set_webhook` (~82 tokens)

Set the settlement webhook URL. Auto-generates the HMAC signing secret on first set; the response returns {url, secret} (secret shown ONCE - store it to verify X-Webhook-Signature). Use uxc_rotate_webhook_secret to rotate, uxc_get_webhook to read it masked.

Input parameters:

- `webhook_url` (string, required)

### `uxc_get_webhook` (~29 tokens)

Read the settlement webhook config (masked): {url, has_secret, secret_last4}.

### `uxc_rotate_webhook_secret` (~28 tokens)

Rotate the HMAC webhook signing secret; returns {secret} (shown once).

### `uxc_verify_webhook_signature` (~172 tokens)

Verify an incoming settlement webhook HMAC signature (constant time). Pure local check - no network. Mirrors the server scheme: HMAC-SHA256 of "<t>.<raw_body>" keyed with the webhook secret, from the X-Webhook-Signature header "t=<unix>,v1=<hex>". Pass the EXACT raw body (do not re-encode). Returns {valid:bool, age_seconds?:int}. Deduplicate by event_id separately.

Input parameters:

- `raw_body` (string, required): the raw request body bytes you received
- `secret` (string, required): the webhook signing secret
- `signature_header` (string, required): the X-Webhook-Signature header value (t=...,v1=...)
- `tolerance` (integer): replay window in seconds; 0 skips the freshness check

### `uxc_set_stripe` (~136 tokens)

Connect the agent own Stripe account so it can accept card payments (the redirect rail). Pass the Stripe secret key, a one-time product id, and the webhook signing secret. The key + product are verified against Stripe before saving. Non-custodial - card payments settle direct to the agent own Stripe account.

Input parameters:

- `product_id` (string, required): prod_...
- `publishable_key` (string): optional pk_live_... or pk_test_...
- `secret_key` (string, required): sk_live_... or sk_test_...

### `uxc_clear_stripe` (~22 tokens)

Disconnect the agent Stripe account (disables card payments).

### `uxc_set_custom_token` (~271 tokens)

Add a custom token (ERC-20/TRC-20/SPL) the agent accepts. type is one of erc-20, bep-20, base-20, polygon-20, arb-20, op-20, avax-20, trc-20, spl. After adding, set a receive address for it with uxc_set_wallet (asset = the code) so buyers can pay it. Custom tokens are auto-detected on-chain like the built-in coins.

Input parameters:

- `code` (string, required): 2-12 lowercase letters/digits; must not collide with a built-in coin
- `confirmations` (integer): optional confirmations to settle (blank = the default)

### `uxc_set_settings` (~91 tokens)

Partially update the agent safe settings. Pass any subset of {confirmations:{default?, coins:{<code>:n}?}, webhook:{url?, rotate_secret?}, currency?, payment:{accept_underpayments?, redirect?}, notifications:{email?}, branding:{brand_name?, logo_url?, logo_url_dark?, color_1?, color_2?, color_3?}}. Only sent fields change.

### `uxc_get_integrations` (~42 tokens)

Read the third-party integration credentials the agent has stored (Discord, Telegram, BigCommerce, Ecwid, Wix). Returned in plaintext to the authenticated agent.

### `uxc_set_integrations` (~62 tokens)

Input parameters:

- `integrations` (object, required): keyed by integration name

### `uxc_set_wallet` (~92 tokens)

Set the agent own receive address for one asset. This is where buyer funds land (non-custodial - the platform never holds them). asset is a code like btc, eth, sol, trx, usdt. address accepts comma-separated for the Address List (3+ addresses for a coin -> exact-amount unique-address payments).

Input parameters:

Remove a coin receive address (stop accepting it). The coin is gone from get_wallets until set_wallet is called again.

Input parameters:

- `asset` (string, required)

### `uxc_create_resource` (~149 tokens)

Create a priced resource the agent sells access to. amount is a fiat price (e.g. 0.01). accepted_assets defaults to all configured wallets; pass a list to restrict. Returns the res_id + a checkout_url (the canonical buyer door on pay.u.cash: /checkout/<enc>?cloud=<token>); the agents.u.cash /r/{res_id} link is a back-compat alias of it.

Input parameters:

Create a ONE-OFF payment request: a pay.u.cash /id/<enc> link that CLOSES when paid or after the expiry (15m/1h/24h/7d/30d/never). Distinct from uxc_create_resource (persistent). The returned `url` is the buyer door on pay.u.cash: a human opens it (HTML checkout), an agent fetches url + ?agent=1 for the 402 manifest, an x402 client sends X-PAYMENT. Use for one-time invoices/links. external_reference makes retries idempotent.

Input parameters:

Input parameters:

- `res_id` (string, required)

### `uxc_verify_payment` (~108 tokens)

BUYER-SIDE. After paying a resource (from uxc_view_door) on-chain from your own wallet, submit the transaction hash to settle it.

No seller key needed - the challengeId identifies the resource, and settlement is gated by on-chain confirmation.

Input parameters:

- `challengeId` (string, required)
- `hash` (string, required)

### `uxc_signup` (~86 tokens)

Register a new agent account (wallet-first: returns an api_key immediately, no email loop). Pass a real email + a strong password; optional primary_wallet. No auth needed - this mints the key you would then set as UXC_API_KEY.

- `options` (array)
- `required` (boolean)
- `type` (string, required)

### `uxc_set_custom_fields` (~56 tokens)

Replace the whole custom-field list; optionally set the form title. custom_fields is a list of {type, name|label+options, required}.

Input parameters:

- `custom_fields` (array, required)
- `title` (string)

### `uxc_delete_custom_field` (~29 tokens)

Remove the custom field at 0-based position index.

Input parameters:

- `index` (integer, required)

### `uxc_get_billing` (~49 tokens)

Show the agent account financials: non-withdrawable credit_balance (USD), fee-credit points, and lander-slot capacity (owned/in-use/free/paid, domain unlocked, pack prices).

### `uxc_buy_lander_pack` (~77 tokens)

Buy a reusable lander-slot pack (debits credit_balance, grows capacity permanently). qty must be a valid pack size (1, 5, 10, 25, 50, 100, 1000, 10000). Returns the new slot snapshot + balance.

Input parameters:

- `qty` (integer, required)

### `uxc_redeem_ucash` (~56 tokens)

Convert fee-credit points into fee credit (an intra-account value move; the merchant MFA step-up gate is skipped for this headless API key). amount is the points to redeem.

Input parameters:

- `amount` (number, required)

### `uxc_get_subagents` (~39 tokens)

List the agent subagents (scoped sa_ API keys with a limited RBAC role). Never returns the api_key. Owner-only.

### `uxc_create_subagent` (~182 tokens)

Create a subagent (owner-only): a scoped sa_ API key with a limited role. role is one of clerk, teller, lead, supervisor, manager, director, officer, admin, master-admin, accountant, auditor, designer, or custom. For custom, pass permissions (capability slugs like transactions.view, checkouts.edit, payment-links.create). Optional store_scope (store ids) restricts the subagent to those stores (empty = all). The sa_ api_key is returned ONCE; a subagent with no free slot debits credit_balance (seat billing).

Input parameters:

- `display_name` (string)
- `permissions` (array): custom-role capability slugs
- `role` (string, required)
- `role_name` (string)
- `store_scope` (array): restrict to these store ids (empty = all stores)

### `uxc_update_subagent` (~96 tokens)

Update a subagent role/permissions/store_scope/status/display_name (owner-only). status is active or suspended (suspending stops the key authenticating).

Input parameters:

- `display_name` (string)
- `permissions` (array)
- `role` (string)
- `role_name` (string)
- `status` (string)
- `store_scope` (array)
- `subagent_id` (integer, required)

### `uxc_rotate_subagent_key` (~48 tokens)

Rotate a subagent api_key (owner-only). The old key stops authenticating; the new sa_ key is returned ONCE.

Input parameters:

- `subagent_id` (integer, required)

### `uxc_delete_subagent` (~39 tokens)

Delete a subagent (owner-only). Its key stops authenticating and the seat slot frees.

Input parameters:

- `subagent_id` (integer, required)

### `uxc_set_resource_cap` (~145 tokens)

Set (or clear, when amount/window_hours are absent) a per-caller spend cap on a resource. A payer whose settled spend in the window reaches amount is refused new authorization. amount is in the resource currency; window_hours is the rolling window; by is "wallet" (default, enforced at verify/settle) or "ip" (enforced at the door before charge, across all rails).

Input parameters:

- `amount` (number): omit/0 to clear the cap
- `by` (string): wallet (default) | ip
- `res_id` (string, required)
- `window_hours` (integer): rolling window (e.g. 24)

### `uxc_get_resource_callers` (~52 tokens)

Per-caller settled-spend audit ledger for a resource: [{caller (wallet), spend, payments}] within the cap window, for reconciliation vs wallet receipts.

Input parameters:

- `res_id` (string, required)
