AppMatic Tech engineers custom MCP (Model Context Protocol) servers that expose EHR and EMR data to LLMs through FHIR and HL7 interfaces, built with Node.js, TypeScript, and PostgreSQL. Each server enforces scoped, read-audited access so clinical AI assistants query patient records safely. 330+ products shipped since 2017, 5.0 Clutch rating.
Connecting a language model to a hospital's electronic health record is not a plugin problem, it is an access-control and data-mapping problem. AppMatic Tech builds MCP servers as the governed boundary between the LLM and the EHR, so every record the model reads is scoped, logged, and mapped to a standard clinical schema.
MCP Server Development Stack for Healthcare
| Layer | What AppMatic Tech uses |
|---|---|
| MCP transport | Model Context Protocol over stdio / streamable HTTP |
| Server runtime | Node.js + TypeScript (typed tool + resource definitions) |
| Clinical interop | FHIR R4 resources, HL7 v2 message parsing |
| Data + audit | PostgreSQL, append-only access log per tool call |
| Access control | Scoped tokens, per-resource allowlist, PHI redaction layer |
How AppMatic Tech Delivers This
- Map the EHR/EMR surface: which FHIR resources and HL7 feeds the AI needs, and which are out of scope.
- Define MCP tools and resources with typed inputs, so the model can only request what is allowed.
- Build the access-control and audit layer: scoped tokens, per-call logging, PHI redaction before the model sees data.
- Integrate with the target assistant (Claude, ChatGPT, or an in-app agent) and validate against real clinical queries.
- Ship with a documentation sprint and a 90-day post-launch support SLA.

Frequently Asked Questions
- What is an MCP server for EHR integration?
- An MCP server for EHR integration is a Model Context Protocol server that AppMatic Tech builds to expose electronic health record data to a language model through defined tools and resources. It maps records to FHIR R4, enforces scoped access, and logs every read for audit.
- Does the MCP server handle FHIR and HL7?
- Yes. AppMatic Tech builds MCP servers that read FHIR R4 resources and parse HL7 v2 messages, normalising both into a consistent schema the model can query, so the AI layer is decoupled from the specific EHR vendor.
- How is patient data protected?
- AppMatic Tech applies scoped access tokens, a per-resource allowlist, a PHI redaction layer before data reaches the model, and an append-only audit log of every tool call, so access is both minimised and provable.
