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": { "command": "node", "args": [ "/Users/your-username/{agentcare-download-path}/agent-care-mcp/build/index.js" ], "env": { "OAUTH_CLIENT_ID": XXXXXX, "OAUTH_CLIENT_SECRET":XXXXXXX, "OAUTH_TOKEN_HOST":, "OAUTH_TOKEN_PATH":, "OAUTH_AUTHORIZE_PATH", "OAUTH_AUTHORIZATION_METHOD": , "OAUTH_AUDIENCE":, "OAUTH_CALLBACK_URL":, "OAUTH_SCOPES":, "OAUTH_CALLBACK_PORT":, "FHIR_BASE_URL":, "PUBMED_API_KEY":, "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)

Use Goose

Goose is an open Source AI Agent frameowrk from Block(Stripe) that works with MCP servers. Goose Desktop is like Claude Desktop that can work with MCP servers. But Goose can be configured to use models other than Anthropic as well. More info: https://block.xyz/inside/block-open-source-introduces-codename-goose

See below how Goose Desktop works with Agent Care: (goose extension will be configured with command: /Users/your-username/{agentcare-download-path}/agent-care-mcp/build/index.js)
