Athenahealth opens patient records to Claude through an MCP server

Patients of practices that run on Athenahealth can now point Claude at their own medical records. The health tech company has launched AthenaPatient MCP, a Model Context Protocol server that lets Anthropic's assistant pull from a patient's chart and answer questions about it, as ZDNET's Nina Raemont reported.

Athenahealth says its software serves more than 20% of the US population, so this is not a pilot at one hospital. It is one of the largest record systems in the country plugging straight into a consumer chatbot.

What actually shipped

The server is available only on Claude Pro and Claude Max, the $20 and $100 a month plans. Nothing is on by default: a patient signs in with their Athenahealth credentials, picks which parts of the record Claude may see, and can revoke access whenever they like.

Once connected, Claude can read lab results, vitals, medications and conditions, plus allergies, immunizations, past visits, procedures, care plans and diagnostic reports. Athenahealth says the data can't be used to train Anthropic's models.

The company is careful about what this is for. Sam Lambson, its vice president of product management for data and ecosystem, told ZDNET the integration does not give medical advice and shouldn't replace a clinician's judgment. So "what was my last red blood cell count?" is in scope. "Should I worry about it?" is a question for your doctor.

Why developers should care

This is what MCP looks like when it leaves the IDE. Most MCP servers developers know connect agents to repos, terminals and SaaS tools. Here a records vendor is shipping a consumer-facing MCP server for some of the most regulated data there is, with sign-in, per-category consent and revocation built into the flow.

That is the pattern to copy, and the part to watch. The source doesn't say how granular the permissions really are, what gets logged when Claude reads a chart, or how long access lasts between sign-ins. Those details decide whether this is a convenience or a liability, and every company planning its own MCP server for sensitive data will face the same questions.

The bigger picture

Big tech and big healthcare keep pairing up: ZDNET points to Microsoft's work with Mayo Clinic on a healthcare model and Boston Children's Hospital's enterprise deal with OpenAI. Patients are already ahead of them. In a Pew Research Center survey, about a third of American adults (34%) said they had gone to a chatbot for medical advice.

The likelier payoff is mundane: fewer "can you explain my test results?" messages landing on doctors between visits. Whether patients end up better informed, or just more confident about things they misread, is still an open question. In Pew's survey, the largest share of people still wanted a human overseeing AI in clinical settings.

Scoreboard update: Draw. Claude gets read access to patient charts, but patients hold the keys and doctors keep the diagnosis.

Stay undead.
