How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (update_scoreboard). See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability70
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 1053 tokens (~95/item across 11 items; 11 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management13
- Stability check failed: schema churn in the 7 days we've observed: 0 tool removals, 0 breaking changes, 1 auth/transport breaks, 6 additions. See how to fix → Fail
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (91% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
create_checkout Start an authorized purchase ~120
Create a private Stripe checkout for a current offer after the user expresses purchase intent. Explain price, duration and annual renewal before proceeding. This tool does not charge a card: give checkoutUrl privately to the buyer for payment authorization. Reuse the exact requestId/input after uncertainty; never create a replacement checkout to retry. Pro and Studio passes accept months=1–12 and never auto-renew; annual offers are recurring. Requires billing:checkout.

create_payment_order Prepare a Stripe CLI payment ~135
Prepare an owner-bound one-time payment order after purchase intent, only when get_service_info pricing.paymentMethods.stripe_cli_pay.available is true. Returns the exact @scorekeeper recipient, USD amount and unique memo for stripe pay. Supports pro_week, pro and studio (1–12 calendar months), never annual subscriptions. This tool sends no money. Separately obtain authorization for the actual Stripe transfer and payer-selected funding account. Reuse identical requestId/input on retry; never pay twice or send without the returned memo.

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_checkout Check payment and access ~66

Only fulfillmentStatus=fulfilled confirms access; CLI output or sender status does not. Poll no more often than pollAfterSeconds (at least 60 seconds). Bank transfers can take business days. Never send a replacement payment while pending. review_required or reversed needs support reconciliation, not another payment.

How do I install the Scorekeeper MCP server?
Scorekeeper is a hosted endpoint at https://www.scorekeeper.co/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the Scorekeeper MCP server?
Scorekeeper is an MCP server listed in the public MCP registry as co.scorekeeper/scorekeeper. Create live scoreboards, connect with OAuth, and prepare checkout or Stripe CLI payments. This page covers its hosted endpoint (https://www.scorekeeper.co/api/mcp).
Is the Scorekeeper MCP server safe to use?
Scorekeeper scores 65 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Scorekeeper MCP server expose?
Scorekeeper exposes 11 tools: get_service_info, get_account, create_checkout, get_checkout, create_payment_order, and 6 more. Their descriptions and schemas cost roughly 812 tokens of context every time the server is loaded.
Does the Scorekeeper MCP server require authentication?
No. We connected to Scorekeeper without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Scorekeeper MCP server still maintained?
Scorekeeper is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
