Anlyon alternative

2 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.

- The description's first verb is "call": a word for a change.

Description, as the server wrote it
Calls GET /v1/index on the Receipts API. Free. Returns row ids and UTC dates (no row content), the row count, the first and last dates, and the list of dates that have rows. Use start and limit to page through row ids. Row content is sold per call through x402 and is not returned here.

Description, as the server wrote it
Calls GET /v1/sample on the Receipts API. Free. Returns one real record row labeled as a sample, with its row id, the paid route and price for that row, and the row as fields and as CSV. It takes no parameters and is not a purchase.

Description, as the server wrote it
Reads GET /.well-known/x402 (and /v1/manifest for the price text) on the Receipts API and returns the paid endpoints with their prices in USDC. Free to call. It never pays and never signs anything. Paying is done by an x402 client against the listed route.

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 private-data or outbound.

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write3: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; receipts_index
receipts_pricing
receipts_sample
Can send data out0: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

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

Findings

Matches of fixed checks, with the text they matched.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json

{
  "permissions": {
    "allow": [
      "mcp__receipts-index__receipts_pricing"
    ],
    "ask": [
      "mcp__receipts-index__receipts_index",
      "mcp__receipts-index__receipts_sample"
    ],
    "deny": []
  }
}

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 receipts-index. Review it before you use it.
