## 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 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it.
  - 1 of 28 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 32/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: the license (PolyForm-Noncommercial-1.0.0) isn't a recognized OSI-approved license.
  - Actively maintained (last published 3 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 61/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 311 tokens (~103/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% 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.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

First indexed and scored.

## MCP tools (3)

### `lookup_return_code` (~103 tokens)

Decide one ACH return code.

Returns the code, its decision row, whether the entry goes again, what has
to change first, the wording for the customer, and whether a named person
acts before anything automatic.

An unknown code is NOT an error and is NOT null. It lands on the
conservative row and comes back with ``matched`` false and a
\``fallback_reason`` saying it fell through rather than matched.

Input parameters:

- `code` (string, required)

### `list_decisions` (~64 tokens)

List the five decision rows and the codes that land on each.

Seventeen codes, five answers. The row is the decision; the code is a cell
inside one. ``default_row`` is where anything unlisted lands, and it is
never row 1.

### `explain` (~74 tokens)

Say which row fired for a code and why.

\``family`` is populated only where the source table itself states one. The
published rulebook is sold rather than free, so a family is never asserted
from memory here; ``family_note`` says which of the two you are looking at.

Input parameters:

- `code` (string, required)
