## Findings

- **warn** Annotations that disagree with the tool in `get_hospital_chargemaster_cost` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "get_hospital_chargemaster_cost" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "get_hospital_chargemaster_cost" says "get": a word for reading.
```

- **warn** Annotations that disagree with the tool in `list_hospital_code_costs` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "list_hospital_code_costs" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `get_code_price_distribution`

- The name "get_code_price_distribution" says "get": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Returns the distribution of every hospital's price for a code_type/code, computed server-side: min/p10/q1/median/q3/p90/max, standard deviation, a histogram, and the real hospital nearest each percentile. Use this instead of paging through list_hospital_code_costs when you want to know how prices spread across hospitals (e.g. "is $12k high for MS-DRG 788?" - pass reference_price to get the number of hospitals priced below it). All figures are in terms of the chosen statistic (default: each hospital's average price).
```

### `get_hospital_chargemaster_cost`

- The name "get_hospital_chargemaster_cost" says "get": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Lookup hospital chargemaster cost
```

### `list_hospital_code_costs`

- The name "list_hospital_code_costs" says "list": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Returns cost stats for every hospital with a matching chargemaster entry for a code_type/code. Use this instead of calling get_hospital_chargemaster_cost once per hospital when comparing prices for the same procedure across hospitals (e.g. "which hospital has the cheapest MS-DRG 652?"). Defaults to returning every matching hospital (currently at most a few hundred) in one call. If the response's next_page_token is non-empty, the result set was truncated: call this tool again passing that exact value as page_token to get the next page, and keep doing so until next_page_token is empty - do not stop after one page and conclude a hospital has no data for this code. The response's total_count field (total across all pages) can be compared against how many results you've accumulated so far as a completeness check.
```

## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `batch_get_hospital_chargemaster_cost`

- The name "batch_get_hospital_chargemaster_cost" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Looks up cost stats for several (code_type, code) pairs at one hospital (identified by hospital_id) in a single call - the batch counterpart to get_hospital_chargemaster_cost. Use this instead of calling get_hospital_chargemaster_cost once per code when pricing a fixed set of codes at one hospital (e.g. cross-linking a curated list of procedures on a hospital's page). Capped at 100 codes per call; a request over that is rejected with INVALID_ARGUMENT rather than silently truncated.
```

### `list_code_types`

- The name "list_code_types" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns every distinct code_type (e.g. CPT, MS-DRG) with catalogued cost data, along with each type's distinct code count and total hospital reports. Unpaginated. Use this to discover which code systems have data before drilling into list_codes.
```

### `list_codes`

- The name "list_codes" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns every distinct code catalogued under a given code_type, paginated, with each code's raw chargemaster description and the number of hospitals reporting it. Use this to discover which codes exist under a code system (e.g. all CPT codes) before looking up prices with get_hospital_chargemaster_cost or list_hospital_code_costs. Pass query to text-search codes/descriptions instead of listing a whole code_type. Pass hospital_id to restrict results to codes that one hospital actually reports.
```

### `list_hospitals`

- The name "list_hospitals" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the hospitals supported by the medprice.ai API, with their hospital_id (opaque handle), EIN, name, structured_locations (addresses with geocoded coordinates where available), last_updated_on, and revision history (with per-revision has_payer_data, revision_id, and added_at - when medprice itself ingested that revision, as opposed to revision_date's source-file-reported update date). Defaults to returning the entire registry (currently a few hundred hospitals) in one call. If the response's next_page_token is non-empty, the result set was truncated: call this tool again passing that exact value as page_token to get the next page, and keep doing so until next_page_token is empty - do not stop after one page and conclude the list is complete. The response's total_count field (total across all pages) can be compared against how many hospitals you've accumulated so far as a completeness check, e.g. before answering questions like 'does medprice.ai cover any hospitals in Iowa'.
```
