## 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.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-medical-codes).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 2 days ago).
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 75/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 631 tokens (~126/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% 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 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 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.

## MCP tools (5)

### `search_icd10` (~97 tokens)

Search ICD-10-CM diagnosis/billing codes by keyword or code (keyless, offline source: NLM). E.g. "type 2 diabetes" -> [{code:"E11.9", description:"Type 2 diabetes mellitus without complications"}].

Input parameters:

- `limit` (number): Max results (1-100, default 15).
- `query` (string, required): A condition name or an ICD-10 code fragment.

### `search_loinc` (~77 tokens)

Search LOINC codes (lab tests & clinical observations) by keyword (keyless). E.g. "hemoglobin a1c" -> LOINC number + long common name.

Input parameters:

- `limit` (number): Max results (1-100, default 15).
- `query` (string, required): A lab test / observation name.

### `search_medical_terms` (~91 tokens)

Search clinical term lists by keyword (keyless): system = "conditions" (problem/diagnosis names), "procedures" (procedure names), or "drugs" (RxTerms drug display names).

Input parameters:

- `limit` (number): Max results (1-100, default 15).
- `query` (string, required): Keyword to search.
- `system` (string, required): conditions | procedures | drugs.

### `search_icd10pcs` (~155 tokens)

Search ICD-10-PCS inpatient procedure codes by keyword or code prefix (keyless, offline: CMS FY2026 order file, 79115 billable codes). Diagnoses are search_icd10; PCS is what a hospital bills the procedure itself under. E.g. "hip replacement" -> [{code:"0SR9019", description:"Replacement of Right Hip Joint with Metal Synthetic Substitute, Cemented, Open Approach"}]; "0SR9" returns that whole family.

Input parameters:

- `limit` (number): Max results (1-100, default 15).
- `query` (string, required): Procedure keywords (all words must appear), or an ICD-10-PCS code prefix like "0SR9".

### `get_icd10pcs` (~156 tokens)

Look up one exact 7-character ICD-10-PCS code, plus the sibling codes for the same procedure on the same body part (keyless, offline: CMS FY2026). E.g. "0SR9019" -> its title plus the other 0SR9* right-hip-replacement codes, which is how you find the uncemented or ceramic alternative to a code you already have.

Input parameters:

- `code` (string, required): A 7-character ICD-10-PCS code, e.g. "0SR9019".
- `siblings` (number): Max sibling codes sharing the first 4 characters (same procedure on the same body part) to include (0-100, default 10).
