Deletes or cancels 1Removes, cancels or revokes something.Claude Code: deny

expense_deleteDelete one expense by id and report what went.No findings
Why it is in this group
- The name "expense_delete" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
Delete one expense by id and report what went. The receipt FILE stays on disk. Deleting a rebilled expense loses the record of what an invoice charged, so correct it with expense_update instead.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: true
- idempotentHint: false
- openWorldHint: false

Can't be undone 5Sends, pays, publishes or merges: once done, it cannot be taken back.Claude Code: ask

expense_addRecord one expense and return its id, its net/VAT split and its billable flag.No findings
Why it is in this group
- The name "expense_add" says "add": a word for a change.
- The input carries an amount (input.amount) and a currency, so it moves money.
Description, as the server wrote it
Record one expense and return its id, its net/VAT split and its billable flag. The response states every default that was applied, so the caller can see what was assumed rather than having to guess.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: false
expense_exportExport the expenses in a date range as csv, xlsx or json and return a download link that is valid for one hour.Can send data out1 finding
Why it is in this group
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
What it can reach
- outboundThe input takes a destination (input.to): what the tool writes goes there.

- The input carries an amount (input.amount) and a currency, so it moves money.

license_activateTurn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.

Not available on the hosted endpoint: it has no filesystem, so there is no receipt file to read or hash.

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.

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write1: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; license_status
Can send data out4: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; expense_export
expense_mark_rebilled
expense_summary
expense_to_invoice

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

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__budget-tracker__expense_list",

  }
}

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 budget-tracker. Review it before you use it.

12 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.
