Open Dental

Model Context Protocol (MCP) server for Open Dental — dental practice management software.

Talk to your Open Dental data from Claude, Cursor, or any MCP client. Read patients, appointments, providers, procedures, recalls. Write communications (phone calls, messages) back to patient charts.

Built against the Open Dental REST API. No existing MCP for Open Dental — this is the first.

What you can do with it

You:   "Pull patient 4523 and show me their last 5 appointments + outstanding recalls."
Claude: *calls get_patient, then find_appointments, then find_recalls*

You:   "Find every recall due this month and draft a friendly reminder for each."
Claude: *calls find_recalls with due_date window, drafts the messages*

You:   "Just got off a call with the Smith family about rescheduling — log it."
Claude: *calls log_communication with the right comm_type + comm_mode*

You:   "What providers are working at clinic 2 tomorrow?"
Claude: *calls list_providers + find_appointments, filters*

Common patterns

Pre-visit brief

User:  I'm seeing patient 4523 at 2pm. Brief me.
Agent: get_patient(patnum=4523)
       find_appointments(patnum=4523, limit=5)
       find_procedurelogs(patnum=4523, limit=10)
       find_recalls(patnum=4523)
       → Summary: patient info, last visits, what's been done, what's due

Recall campaign

User:  Build this week's recall list and draft rebooking messages.
Agent: find_recalls(due_date_start="2026-06-26", due_date_end="2026-07-03")
       → for each: pull patient, draft a friendly message

Post-call documentation

User:  Just took a call from the Smiths about rescheduling next week's cleaning.
Agent: find_patients(lname="Smith", fname="...", phone="...")
       log_communication(
         patnum=<found>,
         comm_datetime="2026-06-26T15:30:00",
         comm_type=1,           # ApptRelated
         comm_mode=2,           # Phone
         sent_or_received=1,    # Received
         note="Patient called to reschedule cleaning. Will call back with new date."
