  What this check looks for
Description, as the server wrote it
Poll a connect request. Returns pending | denied | expired, or — once approved — the app id and the API TOKEN (returned exactly once: save it to the project's .env immediately, never print it in logs). The token is SCOPED (read, invoices, subscriptions, webhooks) — it cannot move money out of the app; transfers/refunds/checks need the primary token the human holds in the Mini App. Poll every 3-5 seconds while pending.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged untrusted-input.

Reads private data2: Reads files, mail, messages, databases, secrets, calendars or repositories.; connect_status
get_docs
Reads text others write0: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out1: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; updateApp

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

Looked at Oct 22, 2026, 14:42 UTC, unchanged since Oct 22, 2026. No credentials were sent and no tool was called. What is looked at.

Reachable: yes
HTTP status of an anonymous initialize: 200
tools/list served without credentials: yes
Tools that change things, listed without credentials: 9
Protocol version: 2025-06-18
WWW-Authenticate on 401: not observed
resource_metadata in WWW-Authenticate: none
RFC 9728 protected resource metadata: none
Authorization servers: none
Legacy HTTP+SSE transport: no
Dynamic client registration: not observed
Client ID metadata documents: not observed

HighThe whole server
The endpoint served tools/list without credentials, and the list has 9 tools that change things (4 destructive, 5 write). Whether a call also works without credentials was not tested: tools are never called.
Matched text
https://app.tgpaycrypto.com/mcp: tools/list returned 20 tools to an anonymous client, including deleteInvoice (destructive), deleteCheck (destructive), archiveSubscriptionPlan (destructive), cancelSubscription (destructive), connect (write) and 4 more

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as merchant-api. Review it before you use it.

Anlyon alternative

9 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
