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

voucher_deleteDelete a voucher entered wrongly, by its VOU number.No findings
Why it is in this group
- The name "voucher_delete" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
Delete a voucher entered wrongly, by its VOU number. One already covered by a reconciliation is refused, naming the count it would falsify: record a correcting voucher instead. Free.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: true
- idempotentHint: false
- openWorldHint: false

Can't be undone 1Sends, pays, publishes or merges: once done, it cannot be taken back.Claude Code: ask

topup_recordRecord cash put into the tin, in whole MINOR units, with the date and source, and return the new balance against the imprest.No findings
Why it is in this group
- The name "topup_record" says "topup": a word that usually means money moves, which cannot be taken back.
Description, as the server wrote it
Record cash put into the tin, in whole MINOR units, with the date and source, and return the new balance against the imprest. It also reimburses every voucher up to that date, as a replenishment does.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: false

float_openOpen a petty cash float on the imprest system and return its id.No findings
Why it is in this group
- The name "float_open" says "open": a word for a change.
Description, as the server wrote it
Open a petty cash float on the imprest system and return its id. The imprest is the cash the tin is topped back up to at every replenishment, in whole minor units. Free tier: one float.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: false
float_reportReport each float: balance against imprest, what it takes to restore it, unreconciled vouchers with their total, the last count, and the history of what counts found over or short.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.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Report each float: balance against imprest, what it takes to restore it, unreconciled vouchers with their total, the last count, and the history of what counts found over or short. Pro.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
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.

replenish_requestWork out what puts the float back to its imprest: the amount, the vouchers it reimburses, the totals per category as an expense_add-ready payload, and the double entry.No findings
Why it is in this group
- The name "replenish_request" says "request": a word for a change.
Description, as the server wrote it
Work out what puts the float back to its imprest: the amount, the vouchers it reimburses, the totals per category as an expense_add-ready payload, and the double entry. Writes nothing. Pro.

voucher_addRecord one voucher paid out of the tin and return its VOU-YYYY-NNNN number.No findings
Why it is in this group
- The name "voucher_add" says "add": a word for a change.
Description, as the server wrote it
Record one voucher paid out of the tin and return its VOU-YYYY-NNNN number. More than the float holds is refused, and so is a byte-identical duplicate. Free tier: 20 vouchers a calendar month.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: false

Description, as the server wrote it

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.

Anlyon alternative

8 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.
