OFAC SDN counterparty screening for an address.

Tokens the platform accepts on an intent, per chain — what create_intent will admit.

Every feature request ever submitted, public and unauthenticated.

Submit a feature request ($1 anti-spam fee, charged to the prepaid balance when funded).

Start wallet sign-in: returns a single-use SIWE message.

Finish wallet sign-in: exchanges the signed SIWE message for a cl_sess_… session token — use it as the Authorization bearer on every authenticated tool.

Identify the authenticated account: address, kind, scopes.

Export all of this account's data in one document.

Close this account for good: revokes every credential, scrubs personal data, retires the account.

Create or update the wallet's treasury policy (immutable versioning; PUT creates the next version).

List policy versions, newest first (the first entry is active).

Pre-flight policy check: would this spend be allowed under the wallet's policy right now?

Pre-flight policy check for a prediction-market order: would this cost be allowed right now?

Poll typed treasury events with a monotonic cursor (intent lifecycle, budget thresholds, reconciliation, security alerts).

Deterministic monthly statement derived from the append-only ledger — same period, same bytes.

Create a conversion or gas_topup intent; the executor pipeline plans and fills it under policy.

Fetch an intent, including fills and the post-trade report once filled.

List intents, newest first.

Cancel a planned intent (a few-second window before execution claims it).

Prepare a scoped session-key grant for a Kernel smart account: exact call allowlist, expiry, optional rate limit.

Activate a prepared delegation by supplying the owner's signature over its enable digest.

Renew an active delegation: same scope, fresh expiry, no authority gap.

Revoke a delegation.

Fetch one delegation.

List delegations, newest first.

Emergency stop, one call: suspends the account, revokes every API key, session, delegation and venue credential, and returns all unwind calldata for the owner.

Prepaid fee balance: settled credits minus fee debits.

Top up the prepaid balance with USDC.

Configure auto-topup: when the prepaid balance falls below threshold_usd, the platform settles one of the pre-signed EIP-3009 authorizations you supply (signed outside MCP — this server cannot sign).

The auto-topup rule and how many pre-signed authorizations remain.

Remove the auto-topup rule and its unused authorizations.

Store a prediction-market venue credential (verified live against the venue, sealed at rest, material never returned).

List stored venue credentials — metadata only, never material.

Revoke a venue credential; its sealed ciphertext is destroyed.

Calldata to swap the Polymarket funder Safe's owner to a new EOA — the owner executes it outside MCP (this server cannot sign).

Place a prediction-market limit order under policy, signed server-side with the stored credential.

The credential's resting orders straight from the venue — recover state after a disconnect.

Cancel one resting prediction-market order.

Cancel every resting order for the credential, optionally within one market.

Prepare a client-signed Polymarket order: policy-checked, then returns the exact EIP-712 payload to sign outside MCP (this server cannot sign) plus a prepare_id — submit both via submit_pm_order.

Submit a prepared Polymarket order with the maker's EIP-712 signature from prepare_pm_order.

Polymarket trade-readiness for an address: live approval status plus the calldata for anything missing (executed outside MCP — this server cannot sign).

Resolve an owner EOA to its Polymarket funder Safe candidates.

Pull the venue's fills for a credential into the wallet's ledger.

Wrap the funder Safe's USDC.
