Medplum MCP

Medplum's own MCP server, for developers and teams building healthcare software on Medplum, the open-source healthcare developer platform. It lets your agent search, read and change the FHIR data stored on a Medplum server, such as patient records, appointments and lab results. Instead of many narrow tools, it gives your agent one general FHIR request tool, because models already know the FHIR standard well. What you can do with it - Search FHIR resources, such as finding patients with a blood pressure observation above a given value - Read records, such as a patient's most recent cholesterol lab results - Create, update and delete resources, such as scheduling an appointment or creating a task - Call Medplum's FHIR operations, such as submitting a Claim or running a Medplum Bot How it connects Medplum hosts it at https://api.medplum.com/mcp/stream. The first time you connect, you're sent to Medplum to sign in and authorize your agent (OAuth). Requests run with your Medplum account's access. It has three tools: fhir-request, which does the real work, plus search and fetch, which some clients such as ChatGPT need in order to connect. A self-hosted Medplum server serves the same endpoint at /mcp/stream. Good to know - fhir-request can change data: it can create, update and delete FHIR resources. - It's a developer tool for working with data on a Medplum server. It doesn't give medical advice, and what your agent says about the data isn't a clinical judgement. - Medplum describes its platform as HIPAA and SOC 2 compliant. When it launched MCP support, it called it a preview, asked people to use only synthetic, de-identified or test data rather than protected health information (PHI), and noted that most major AI providers didn't yet sign HIPAA business associate agreements (BAAs). Check with Medplum and your agent's provider before you connect real patient data.
