Over the last week it answered 68.6% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 18

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

capability
capability.get
FREE, read-only x402 capability detail lookup. Supply the exact capability name returned by capabilities.list to receive one deterministic capability definition and advertised price; no payment or execution occurs. Use capability.quote when x402 challenge requirements are needed.
capability.quote
FREE, read-only x402 quote/challenge lookup. Supply the exact capability name returned by capabilities.list to receive v1 and v2 payment requirements without execution or settlement. Use capability.get for metadata only and execution.preflight for the cross-domain authorization decision.
payment
payment.methods
FREE, read-only payment-rail discovery. Returns supported Stripe, prepaid-credit, and x402 rails plus the receiver-only wallet authority boundary; it never signs or spends. Use this when selecting a payment rail before any authorization step.
payment.verify
FREE, read-only Base USDC verification. Provide a Base transaction hash, a CrossingKey receipt ID, or both to verify the receiver transfer and optionally reconcile an existing receipt; it never signs, sends, settles, swaps, bridges, or spends funds. Use receipt.verify for local receipt integrity without chain lookup.
capabilities
capabilities.list
FREE, read-only x402 capability list. Use this only for deterministic machine-commerce capabilities priced for x402 execution; it does not list the full CrossingKey offer/service catalog and never executes a capability. For public offers use offers.list.
cost
cost.estimate
FREE, read-only cross-domain price lookup. Supply an offer or capability identifier to return the currently advertised USD price or request-credit cost; no payment, reservation, or credit consumption occurs. For x402 challenge terms use capability.quote instead.
credits
credits.options
FREE, read-only prepaid-credit purchase discovery. Returns available request-credit packs and their existing Stripe Payment Links; it does not open a checkout session or spend funds. Use this only when prepaid request credits are the intended payment rail.
entitlement
entitlement.inspect
FREE, read-only entitlement inspection. Supply a CrossingKey entitlement identifier to return current entitlement state without granting execution, download access, or paid result content. Use purchase.status when only an idempotency key is available.
execution
execution.preflight
FREE, read-only final preflight before any paid action. Supply an offer or capability identifier to receive payment method, exact advertised price, readiness, safety warnings, and next action; this tool never charges or executes. Call it after discovery and requirement checks, not as a replacement for paid execution.
health
health
FREE, read-only MCP readiness check. Returns service, Stripe, machine-commerce, mainnet-gate, and receiver-only wallet readiness flags without contacting payment rails or changing state. Use this for operational readiness, not purchase status.
offers
offers.list
FREE, read-only canonical offer search. Use this to find public digital or service offers by query, kind, or maximum USD price before payment; it returns metadata only and creates no checkout session. Use capability.get only for x402 capability detail; offer details are returned by offers.list.
provider
provider.describe
FREE, read-only provider discovery. Use this first to learn CrossingKey identity, commerce model, payment rails, authority boundaries, and recommended next actions; it never creates a payment or executes paid work. For offer-specific data use offers.list and capability.get, and for x402 terms use capability.get/capability.quote.
purchase
purchase.status
FREE, read-only x402 purchase-status lookup. Supply the original idempotency key to retrieve purchase state and integrity identifiers without revealing paid result content or changing state. The response includes purchase, entitlement, and result-integrity identifiers when available.
receipt
receipt.verify
FREE, read-only receipt integrity verification. Supply a CrossingKey receipt object to recompute and compare its deterministic result hash; this performs no payment, entitlement mutation, or network settlement. A true result verifies integrity only, not external payment finality.
requirements
requirements.check
FREE, read-only prerequisite check. Supply an offer or capability identifier to receive payment, authorization, fulfillment, and idempotency requirements without creating a payment. Use execution.preflight for the final machine-readable go/no-go decision.
result
result.preview
FREE, read-only result preview. Supply an offer or capability identifier to see the expected fulfillment or output shape without exposing paid content or executing work. Use this after offers.list or capabilities.list when an agent needs to evaluate the result contract before authorization.
services
services.list
FREE, read-only service catalog. Returns only request services explicitly approved by the server's safety process and may legitimately be empty; it creates no order or payment. Use this when evaluating approved request-service availability.
xkey
xkey.validate
PAID bounded intake validation. Requires an authenticated prepaid-credit principal, an 8-160 character idempotency key, and 2-100000 characters of raw intake; one credit is committed only on verified success, while safe validation failures release the reservation. Do not call speculatively; use requirements.check and execution.preflight first.

Revenue MCP — questions

Answers built from our own checks of this server.

What can Revenue MCP do?
It exposes 18 tools, read directly from the server on our last check. Among them: capabilities.list, capability.get, capability.quote, cost.estimate, credits.options, entitlement.inspect and 12 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 Revenue MCP mostly used for?
Its tools cluster around payment and capability. 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 Revenue MCP working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 87 of 92 checks got a reply (94.6%), average response time 497 ms. The bar chart above shows every period we have measured.
Did Revenue MCP ever remove tools?
Yes. get_fulfillment_status, get_stripe_checkout_link, list_stripe_offers, check_requirements and 14 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect Revenue MCP?
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 Revenue MCP need an API key?
No. Revenue MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 18 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Revenue MCP?
It answers our handshake in 497 ms on average, which is faster than 29% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
