Tools

FHIR Tools

• find_patient - Search for a patient by name, DOB, or other identifiers
• get_patient_observations - Retrieve patient observations/vital signs
• get_patient_conditions - Get patient's active conditions
• get_patient_medications - Get patient's current medications
• get_patient_encounters - Get patient's clinical encounters
• get_patient_allergies - Get patient's allergies and intolerances
• get_patient_procedures - Get patient's procedures
• get_patient_careteam - Get patient's care team members
• get_patient_careplans - Get patient's active care plans
• get_vital_signs - Get patient's vital signs
• get_lab_results - Get patient's laboratory results
• get_medications_history - Get patient's medication history
• 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.

  • https://clinicaltrials.gov/api/v2/studies
  • https://eutils.ncbi.nlm.nih.gov/entrez/eutils
  • https://api.fda.gov/drug/ndc.json

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": {

  }
}

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)
