## Findings

No check matched anything in these tool definitions.


## Only reads (4)

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

### `canvas_get_capability_statement`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch the server's FHIR CapabilityStatement — exactly which resources, interactions and search parameters this Canvas instance supports. Read it when a search is rejected and you want to know what the instance actually accepts. Canvas: GET /metadata.
```

### `canvas_get_patient_everything`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch a patient's full record in one FHIR bundle — conditions, medications, observations, encounters and more. The fastest way to answer a broad question about one person, but it can return a large document, so prefer canvas_search when you know which resource you need. Canvas: GET /Patient/{id}/$everything.
```

### `canvas_read`

- The name "canvas_read" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch a single FHIR resource by type and id. Canvas: GET /{resource}/{id}.
```

### `canvas_search`

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

Description, as the server wrote it:

```untrusted-server-text
Search any supported FHIR R4 resource in the chart. Pick `resource`, then narrow with the standard FHIR search parameters. Nearly every clinical question starts here: Condition or Observation for a problem list and results, MedicationRequest for prescriptions, Appointment or Encounter for visits, DocumentReference for notes. Canvas: GET /{resource}.
```
