Tools 4

Tool	Type	What it does
`canvas_search`	read	Search a FHIR resource 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}.
`canvas_read`	read	Read one FHIR resource Fetch a single FHIR resource by type and id. Canvas: GET /{resource}/{id}.
`canvas_get_patient_everything`	read	Get everything for one patient 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_get_capability_statement`	read	Get the FHIR capability statement 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.
