## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (2)

Removes, cancels or revokes something. Claude Code: deny.

### `particle_create_query`

- The name "particle_create_query" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
⚠[U+FE0F] WRITE: initiate a nationwide clinical-record retrieval for a patient. Returns a query_id — poll particle_get_query_status for progress. Endpoint: POST /api/v2/patients/{particle_patient_id}/query.
```

### `particle_submit_patient`

- The name "particle_submit_patient" says "submit": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
⚠[U+FE0F] WRITE: register a new patient with Particle Health. Returns the patient with a system-generated particle_patient_id (use it for subsequent queries). Endpoint: POST /api/v2/patients.
```

## Only reads (9)

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

### `particle_get_ccda`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve the patient's C-CDA clinical document(s). May be large and returned as XML/text — parsed if JSON, otherwise passed through as-is. Endpoint: GET /api/v2/patients/{particle_patient_id}/ccda.
```

### `particle_get_fhir`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve the patient's complete clinical record as a FHIR searchset Bundle. Supports incremental sync and pagination. Endpoint: GET /api/v2/patients/{particle_patient_id}/fhir.
```

### `particle_get_fhir_by_type`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve only one FHIR resource type for a patient (e.g. Condition, MedicationRequest, Observation) as a Bundle. Supports the same pagination as particle_get_fhir. Endpoint: GET /api/v2/patients/{particle_patient_id}/fhir/{type}.
```

### `particle_get_flat`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve the patient's clinical data in Particle's flattened (de-nested) format, easier to read than raw FHIR. Optionally filter to one domain. Endpoint: GET /api/v2/patients/{particle_patient_id}/flat.
```

### `particle_get_patient`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch a single patient record by its Particle patient id. Endpoint: GET /api/v2/patients/{particle_patient_id}.
```

### `particle_get_patient_documents`

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

Description, as the server wrote it:

```untrusted-server-text
List the documents uploaded / available for a patient. Endpoint: GET /api/v1/documents/{patient_id}.
```

### `particle_get_query_status`

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

Description, as the server wrote it:

```untrusted-server-text
Get the status of a clinical-record retrieval query (state, timing, demographics, files). Omit query_id to get the latest COMPLETE query. Endpoint: GET /api/v2/patients/{particle_patient_id}/query.
```

### `particle_search_network_participants`

- The name "particle_search_network_participants" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the health-data network participants (organizations Particle can query). Optionally filter by state or zipcode, and page with continuation_token. Endpoint: GET /api/v1/networkparticipants (with /state/{state} and /zipcode/{zip} variants).
```

### `particle_search_patient`

- The name "particle_search_patient" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search for an existing patient by demographics (non-mutating). Returns an array of matching patient objects (or a 204 message when none match). Endpoint: POST /api/v2/patients/search.
```
