Nothing to run from here
Supplier Invoice Duplicates is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Review duplicate supplier invoice candidates with grouped local evidence; no payment approval.
Quickstart
Install it the way its author documents:
1. Download duplicate-invoice-check.mcpb and open it in Claude Desktop or another client that installs MCP bundles (.mcpb)
2. Its sha256 is 181379eb6dcff3d90b55e080dd9c180f6c96802e991872865a6b0ce422b3aaea

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts Supplier Invoice Duplicates as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.

Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Read from its source code. A server that builds its tool list when it starts can list more tools than this.
Group up to 1000 supplied records by exact/normalized reference or exact amount/date within exact entity, supplier, type and currency. All evidence is free. Candidates require review; no payment approval.
No parameter schema on file.
List saved report ids, timestamps and unique candidate counts. Free on both tiers. Up to 100 reports per page.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| offset | integer | no | — |
| limit | integer | no | — |
Read a saved report with source records, reason groups and overlap-safe candidate counts. Large reports return free paging instructions.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | — |
Read free pages of records, group summaries, record reasons or one group’s members. Unsaved preview ids last 30 minutes for the last two checks in this process.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | — |
| section | string | yes | — |
| offset | integer | no | — |
| limit | integer | no | — |
| group_id | string | no | — |
Delete one local saved report and free a storage slot. Does not change accounting records.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | — |
Export free CSV pages from a saved report or unsaved preview. One row per record with reasons and group ids. Formula-like cells are escaped; no financial-loss total is calculated.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | — |
| offset | integer | no | — |
| limit | integer | no | — |

ATrust score 96 / 100
Release 0.22.8 · scanned 28 Oct 2026
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

Score vectorthreat 100 → client 96
| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | moderate | capability blast radius (moderate) — client exposure if the model is manipulated | −3 |
| verification-discount | repo | publisher verification (public source) — no provenance, but the source is public and inspectable | −1 |
| coverage-honesty | source | inspection depth (source) — how much of the target the scan could see | −0 |
score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
Tool surfaceread
Implementation sourceread
Package metadataread
Live transportnot available
Tools were statically extracted from the published source (200 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Tool recovery stopped early in scripts/validate.mjs, servers/amortization/src/index.ts, servers/asset-register/src/index.ts and 11 more — the file registers more tools than the scanner reads in one file, so some may be missing from this surface.
servers/clauses/src/store.ts (7 KB) was not read: over the file-count budget.
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. moderate is the level these add up to.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.

Untrusted input can drive an external action even though no sensitive source is exposed.

Scanned2026-10-28
This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
It installs from its repository rather than from a versioned package, so the command cannot be pinned to a release. The history below is for reading; the current release on file is 0.22.8.

no reviews yet
Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Supplier Invoice Duplicates can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
