Nothing serious here today

Today is the operative word: we check Cofferline every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 47

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

auto

get_auto_topup

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

remove_auto_topup

Remove the auto-topup rule and its unused authorizations. Auth required.

set_auto_topup

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). Auth required.

cancel

cancel_all_pm_orders

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

cancel_intent

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

cancel_pm_order

Cancel one resting prediction-market order. Auth required.

intent

create_intent

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

get_intent

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

order

check_pm_order

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

create_pm_order

Place 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.

prepare

prepare_delegation

Prepare 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 confirm_delegation with the signature. Auth required.

prepare_pm_order

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. Auth required.

revoke

revoke_delegation

Revoke a delegation. The reply includes calldata the owner can send on-chain for hard finality. Auth required.

revoke_pm_credential

Revoke a venue credential; its sealed ciphertext is destroyed. Auth required.

submit

submit_feedback

Submit 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, recipient, EIP-712 domain). Sign a transferWithAuthorization for them outside MCP (this server cannot sign), then call again with x_payment set to the base64 of {x402Version:1, scheme:'exact', network, payload:{signature, authorization}}.

submit_pm_order

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

balance

get_balance

Prepaid fee balance: settled credits minus fee debits. Auth required.

benchmarks

get_benchmarks

Measured execution benchmarks: median savings vs arrival quote by USD size bucket, from real completed intents only. Free, no auth.

complete

complete_siwe_login

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. Free, no auth.

confirm

confirm_delegation

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

credentials

list_pm_credentials

List stored venue credentials — metadata only, never material. Auth required.

delegation

get_delegation

Fetch one delegation. Auth required.

delegations

list_delegations

List delegations, newest first. Auth required.

export

export_account

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

feedback

list_feedback

Every feature request ever submitted, public and unauthenticated. Free.

get

get_me

Identify the authenticated account: address, kind, scopes. Auth required.

intents

list_intents

List intents, newest first. Auth required.

offboard

offboard_account

Close 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.

onboarding

get_pm_onboarding

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

orders

list_pm_orders

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

panic

panic

Emergency 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.

policy

get_policy

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

poll

poll_events

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

put

put_policy

Create 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 take the platform defaults published in the manifest and are stored into the document, and the response lists them in `defaulted`.

quotes

get_quotes

Live venue quote comparison for a token conversion (CoW + ParaSwap on Base). Free, no auth.

renew

renew_delegation

Renew an active delegation: same scope, fresh expiry, no authority gap. Returns a NEW digest to sign and confirm exactly like prepare_delegation. Auth required.

resolve

resolve_pm_funder

Resolve an owner EOA to its Polymarket funder Safe candidates. Auth required.

screen

screen_address

OFAC SDN counterparty screening for an address. Free, no auth.

signer

get_pm_signer_rotation

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

spend

check_spend

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

start

start_siwe_login

Start 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.

statement

get_statement

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

store

store_pm_credential

Store 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 + passphrase + maker + signer. Auth required.

sync

sync_pm_fills

Pull the venue's fills for a credential into the wallet's ledger. Idempotent — safe to repeat. Auth required.

tokens

list_tokens

Tokens the platform accepts on an intent, per chain — what create_intent will admit. Free, no auth.

topup

topup_balance

Top 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 transferWithAuthorization for them outside MCP (this server cannot sign), then call again with x_payment set to the base64 of {x402Version:1, scheme:'exact', network, payload:{signature, authorization}}.

wrap

wrap_pm_usdc

Wrap the funder Safe's USDC.e into Polymarket's pUSD, platform-relayed so the user pays no gas. Omit amount_base_units to wrap the full balance. Auth required.

Cofferline — questions

Answers built from our own checks of this server.

What can Cofferline do?

It exposes 47 tools, read directly from the server on our last check. Among them: cancel_all_pm_orders, cancel_intent, cancel_pm_order, check_pm_order, check_spend, complete_siwe_login and 41 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Cofferline mostly used for?

Its tools cluster around cancel, auto and submit. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Cofferline working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 150 ms. The bar chart above shows every period we have measured.

How do I connect Cofferline?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Cofferline need an API key?

No. Cofferline completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 47 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Cofferline?

It answers our handshake in 150 ms on average, which is faster than 81% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
