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. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-hospital-prices). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 3 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability56
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1222 tokens (~407/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

Stability & Change Management23
- Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
hospital_price_compare ~319
Side-by-side prices for one service at up to 10 named hospitals (by CMS Certification Number, CCN, from hospital_price_search or hospital_price_coverage). Same fields and same labelling as hospital_price_search: gross charge vs self-pay cash vs payer-negotiated rates, dollar_available on every negotiated rate, and for each hospital that has no price a stated reason (not held and why / code absent / payer not listed). Use for "compare MS-DRG 470 at these three hospitals for Blue Cross".
| Name | Type | Req | Description |
|---|---|---|---|
| ccns | array | yes | CMS Certification Numbers (6 characters, e.g. "330101"), 1-10. |
| code | string | yes | The service code: a CPT/HCPCS code from the CMS 70 shoppable services (e.g. "70450" head CT, "45378" colonoscopy, "99213"-style E&M codes only where on that list) or an MS-DRG number (e.g. "470" majo… |
| code_type | string | – | Optional. Inferred when omitted: 1-3 digits is an MS-DRG, a 5-character code is CPT/HCPCS. |
| payer | string | – | Case-insensitive substring of the payer name. |
| plan | string | – | Case-insensitive substring of the plan name. |
| rates_per_hospital | number | – | Negotiated rows per hospital (1-25, default 25). |
| setting | string | – | Restrict to inpatient or outpatient pricing. |
No output schema declared.
No examples provided.
hospital_price_coverage ~253
Whether this store holds a hospital's prices and, if not, WHY. Look up one hospital by CCN or by name (partial match), or summarise a state, or (no arguments) the whole store, including which states are loaded (the store is loaded state by state, so a hospital in an unloaded state is simply absent). Every hospital in a loaded state has a status: ok (prices held), blocked (its website refuses our requests; we do not evade blocks), not_found (no machine-readable file found), invalid_pointer, soft_404, unsupported_version, too_large, parse_error, no_matching_codes, not_fetched. Use before trusting an empty hospital_price_search, or to answer "does this tool cover Mayo Clinic".
| Name | Type | Req | Description |
|---|---|---|---|
| ccn | string | – | CMS Certification Number, e.g. "330101". |
| name | string | – | Hospital name or part of it, e.g. "Mayo Clinic". Up to 25 matches are returned. |
| state | string | – | Two-letter state code, e.g. "MN": counts by status for that state. |
| status | string | – | With state: list hospitals having this status (e.g. "blocked"). |

hospital_price_search ~595
What hospitals near a US ZIP charge for one service, from the standard charges files each hospital publishes under the CMS price transparency rule. Per hospital: gross charge (list price, not what anyone pays), self-pay discounted cash price, the de-identified min/max negotiated amounts, and a summary of payer-specific negotiated dollar rates; pass payer and/or plan to get that payer's negotiated rate rows. Each rate carries dollar_available: when a hospital published a percentage or formula instead of a dollar amount it says so and gives the hospital's own text rather than a number. COVERAGE IS PARTIAL AND STATED (the store is loaded state by state; each response lists the states loaded): every response says how many hospitals in range have prices loaded, why others do not (the hospital's site blocks us, no file found, ...), and distinguishes "no hospital in range", "hospital held but code absent" and "code present but payer not listed". Holds only the CMS 70 shoppable CPT/HCPCS services and MS-DRGs. Use for "what does a head CT cost near 02139", "MS-DRG 470 near 10016 for Aetna".
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | The service code: a CPT/HCPCS code from the CMS 70 shoppable services (e.g. "70450" head CT, "45378" colonoscopy, "99213"-style E&M codes only where on that list) or an MS-DRG number (e.g. "470" majo… |
| code_type | string | – | Optional. Inferred when omitted: 1-3 digits is an MS-DRG, a 5-character code is CPT/HCPCS. |
| limit | number | – | Hospitals to return (1-50, default 20), nearest first. |
| near | string | yes | A 5-digit US ZIP ("10016") or "lat,lon" ("40.7459,-73.9780"). |
| payer | string | – | Case-insensitive substring of the payer name (e.g. "aetna", "blue cross"). Returns that payer's negotiated rows. Major payer families are matched under their other spellings too ("blue cross" also fi… |
| plan | string | – | Case-insensitive substring of the plan name (e.g. "ppo", "medicare advantage"). |
| radius_mi | number | – | Search radius in miles (1-150, default 25). Straight-line, from ZIP centroid to the hospital's ZIP centroid. |
| rates_per_hospital | number | – | With payer/plan: negotiated rows per hospital (1-25, default 5). |
| setting | string | – | Restrict to inpatient or outpatient pricing. Default: both. |
