Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

canvas_get_capability_statement Read-only

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.

This tool takes no arguments.

canvas_get_patient_everything

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.

read-only

Argument	Type	Description
_count	integer	Page size, 1-100.
patient_id*	string	The Patient resource id.

canvas_search

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}.
