clinical_query - Execute custom FHIR queries

Medical Research Tools

search-pubmed - Search PubMed articles related to medical conditions
search-trials - Find relevant clinical trials
drug-interactions - Check drug-drug interactions

Usage

Each tool requires specific parameters:

Required Parameters

Most tools require patientId
Some tools have additional parameters:
- lab_trend_analysis: requires labType
- search-pubmed: requires query and optional maxResults
- search-trials: requires condition and optional location
- drug-interactions: requires drugs array

Development Configuration

To use with Cerener: Go to https://code-console.cerner.com and create a sandbox account, create a new provider app and get the clientId/secret. (note: ec2458f2-1e24-41c8-b71b-0e701af7583d below is the tenant id for cerner developer sandbox)
To use with Epic: Go to https://fhir.epic.com/Developer/Apps , sign up as developer and create a new app and get the clientId/secret.
For PubMed, Clinical Trials and FDA, you need to get the API keys from the respective websites.

For local testing Create a .env file in the root directory or use these environment variables in claude desktop launch configuration.

Start MCP Server Locally

git clone {agentcare-mcp-github path}
cd agentcare-mcp
npm install
npm run build

Use claude desktop

for claude desktop: 
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
(use the env variables as shown above)

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "/Users/your-username/Desktop"
      ]
    },
    "agent-care": {
      "command": "node",
      "args": [
        "/Users/your-username/{agentcare-download-path}/agent-care-mcp/build/index.js"
      ],
      "env": {
        "clientId": XXXXXX,
        "clientSecret":XXXXXXX,
        "tokenHost":,
        "tokenPath":,
        "authorizePath",
        "authorizationMethod": ,

        "CLINICAL_TRIALS_API_KEY":,
        "FDA_API_KEY":
      }
    }
  }
}

Use MCP Inspectopr

(MCP Server using inspector. Make sure to update the .env file with the correct values.)

npm install -g @modelcontextprotocol/inspector
mcp-inspector  build/index.js
http://localhost:5173

Test User Logins

(commonly used for sandbox/dev)

Cerner: portal | portal
Epic: FHIRTWO | EpicFhir11!

Troubleshooting:

If Claude desktop is running it uses port 3456 for Auth. You need to terminate that process using the following command:

kill -9 $(lsof -t -i:3456)
