## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-19.

- **Supply Chain Security**: 23/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs were checked across the 92 of 92 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - 31 of 92 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 2 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 547 tokens (~68/item across 8 items; 8 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 75/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 26% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## Install

### How do I install the io.github.theluckystrike/supplier-invoice-matching MCP server?

io.github.theluckystrike/supplier-invoice-matching ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. Before opening it, check the file's SHA-256 matches the one the MCP registry declares for it, 6397928ec44ea9d5c406a66f4eb7aa9a2f34f5731bf8ef9972fadfdac882f040; the commands to do that are on this page. If it does not match, do not open it.

Input parameters:

- `invoice` (object, required)
- `po` (object, required)
- `prior_invoiced` (array, required): Cumulative previously invoiced whole units, excluding this invoice; [] explicitly asserts none. Caller must supply complete history.
- `receipts` (array, required)
- `save` (boolean)

### `report_list` (~53 tokens)

List saved report ids, timestamps, document references, status and issue counts. Free on both tiers; paginated, up to 100 reports per call.

Input parameters:

- `limit` (integer)
- `offset` (integer)

### `report_get` (~45 tokens)

Get a saved matching report

Read a saved report with source documents, per-SKU evidence and all exceptions. Free on both tiers.

Input parameters:

- `id` (string, required): Saved UUID from report_list or three_way_match

### `report_page` (~92 tokens)

Read a page of complete matching evidence

Read free pages of large report issues, SKU rows or original source rows. Use report_id from the paginated overview. Unsaved previews expire after 30 minutes and keep only the last two large checks.

- `receipt_index` (integer)
- `section` (string, required)

Input parameters:

- `id` (string, required): Saved UUID from report_list or three_way_match

### `report_export_csv` (~76 tokens)

Export saved report line evidence as CSV

Return CSV of saved SKU quantities, prices and issues. Large CSVs paginate; follow next_offset with offset. Formula-like text is escaped. Full source evidence uses report_get/report_page.

Input parameters:

- `id` (string, required): Saved UUID from report_list or three_way_match
- `limit` (integer)
- `offset` (integer)

### `license_status` (~54 tokens)

License status

### `license_activate` (~71 tokens)

Activate license

Activate a Pro key (MCPL1.xxx.yyy) from checkout: verified offline against a built-in public key, saved to your config file. A wrong, malformed or expired key is refused, unsaved. license_status reads it back.

Input parameters:

- `key` (string, required): License key from the checkout confirmation page
