Tools it offers

47 tools, as the server itself reported during our check on Oct 31, 2026.

• get_quotesLive venue quote comparison for a token conversion (CoW + ParaSwap on Base). Free, no auth.
• get_benchmarksMeasured execution benchmarks: median savings vs arrival quote by USD size bucket, from real completed intents only. Free, no auth.
• screen_addressOFAC SDN counterparty screening for an address. Free, no auth.
• list_tokensTokens the platform accepts on an intent, per chain — what create_intent will admit. Free, no auth.
• list_feedbackEvery feature request ever submitted, public and unauthenticated. Free.
• submit_feedbackSubmit a feature request ($1 anti-spam fee, charged to the prepaid balance when funded). Auth required. Payment flow: call once without x_payment — a 402 reply lists the exact EIP-3009 requirements (amount, USDC asset, r
• start_siwe_loginStart wallet sign-in: returns a single-use SIWE message. Sign it with the wallet outside MCP (this server cannot sign), then call complete_siwe_login. Free, no auth.
• complete_siwe_loginFinish wallet sign-in: exchanges the signed SIWE message for a cl_sess_… session token — use it as the Authorization bearer on every authenticated tool. Free, no auth.
• get_meIdentify the authenticated account: address, kind, scopes. Auth required.
• export_accountExport all of this account's data in one document. Auth required.
• offboard_accountClose this account for good: revokes every credential, scrubs personal data, retires the account. Irreversible; confirm_wallet_address must be the account's own wallet address, typed exactly. Auth required.
• put_policyCreate or update the wallet's treasury policy (immutable versioning; PUT creates the next version). Auth required. Body must match /schemas/policy-v1.json — only version, wallet and chain_id are required; omitted fields
• get_policyList policy versions, newest first (the first entry is active). Auth required.
• check_spendPre-flight policy check: would this spend be allowed under the wallet's policy right now? Auth required.
• check_pm_orderPre-flight policy check for a prediction-market order: would this cost be allowed right now? Auth required.
• poll_eventsPoll typed treasury events with a monotonic cursor (intent lifecycle, budget thresholds, reconciliation, security alerts). Auth required.
• get_statementDeterministic monthly statement derived from the append-only ledger — same period, same bytes. Auth required.
• create_intentCreate a conversion or gas_topup intent; the executor pipeline plans and fills it under policy. Auth required.
• get_intentFetch an intent, including fills and the post-trade report once filled. Auth required.
• list_intentsList intents, newest first. Auth required.
• cancel_intentCancel a planned intent (a few-second window before execution claims it). Auth required.
• prepare_delegationPrepare a scoped session-key grant for a Kernel smart account: exact call allowlist, expiry, optional rate limit. Returns the ONE EIP-712 digest the account owner signs outside MCP (this server cannot sign) — then call c
• confirm_delegationActivate a prepared delegation by supplying the owner's signature over its enable digest. Auth required.
• renew_delegationRenew an active delegation: same scope, fresh expiry, no authority gap. Returns a NEW digest to sign and confirm exactly like prepare_delegation. Auth required.
• revoke_delegationRevoke a delegation. The reply includes calldata the owner can send on-chain for hard finality. Auth required.
• get_delegationFetch one delegation. Auth required.
• list_delegationsList delegations, newest first. Auth required.
• panicEmergency stop, one call: suspends the account, revokes every API key, session, delegation and venue credential, and returns all unwind calldata for the owner. Auth required.
• get_balancePrepaid fee balance: settled credits minus fee debits. Auth required.
• topup_balanceTop up the prepaid balance with USDC. Auth required. Payment flow: call once without x_payment — a 402 reply lists the exact EIP-3009 requirements (amount, USDC asset, recipient, EIP-712 domain). Sign a transferWithAutho
• set_auto_topupConfigure 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). Auth required.
• get_auto_topupThe auto-topup rule and how many pre-signed authorizations remain. Auth required.
• remove_auto_topupRemove the auto-topup rule and its unused authorizations. Auth required.
• store_pm_credentialStore a prediction-market venue credential (verified live against the venue, sealed at rest, material never returned). Polymarket, either shape: signer_private_key + maker (derives API creds), or api_key + secret + passp
• list_pm_credentialsList stored venue credentials — metadata only, never material. Auth required.
• revoke_pm_credentialRevoke a venue credential; its sealed ciphertext is destroyed. Auth required.
• get_pm_signer_rotationCalldata to swap the Polymarket funder Safe's owner to a new EOA — the owner executes it outside MCP (this server cannot sign). Auth required.
• create_pm_orderPlace a prediction-market limit order under policy, signed server-side with the stored credential. Polymarket: condition_id, token_id, action, price_usd (e.g. '0.55'), size_shares. Auth required.
• list_pm_ordersThe credential's resting orders straight from the venue — recover state after a disconnect. Auth required.
• cancel_pm_orderCancel one resting prediction-market order. Auth required.
