AgentCare (FHIR EMR) MCP server for AI agents

Agent Care is a Model Context Protocol (MCP) server that facilitates integration between AI assistants and Electronic Medical Record (EMR) systems like Cerner and Epic. It provides healthcare tools for interacting with FHIR data, accessing medical resources, and performing clinical analyses through Claude Desktop or Goose Desktop.

Using with Claude Desktop

To use Agent Care with Claude Desktop, modify the Claude Desktop configuration file:

Location of Configuration File

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Configuration Example

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "/Users/your-username/Desktop"
      ]
    },
    "agent-care": {
      "command": "node",
      "args": [
        "/Users/your-username/path-to-agent-care/agent-care-mcp/build/index.js"
      ],
      "env": {

Using with MCP Inspector

You can test the MCP server using the MCP Inspector tool:

npm install -g @modelcontextprotocol/inspector
mcp-inspector build/index.js

Then open http://localhost:5173 in your browser.

Using with Goose Desktop

Goose Desktop is an alternative to Claude Desktop that works with MCP servers and can be configured to use various AI models. Configure Goose Desktop to use Agent Care by adding it as an extension and specifying the path to the built server:

/Users/your-username/path-to-agent-care/agent-care-mcp/build/index.js

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
