Anthropic (Claude)

Configure Anthropic Claude to access b.well's healthcare data and services through b.well Health SDK for AI. This guide includes configuration parameters and code examples for quickly setting up the MCP client in Anthropic's Messages API.

Prerequisites

Install the Anthropic Python library:

pip install anthropic

Required Credentials:

Credential	Source	Notes
Anthropic API Key	Anthropic platform account	Required for all requests
b.well User Token	OAuth 2.0 Token Exchange	Bearer token for user authentication

MCP Configuration Parameters:

Anthropic connects to b.well's MCP server through the tools parameter in the Messages API. Configure the MCP tool with these parameters:

Parameter	Value	Description
`type`	`"url"`	Indicates URL-based MCP integration
`name`	`"bwell-mcp-fhir-agent"`	Identifier for b.well MCP server
`url`	`https://mcpfhiragent.{ENVIRONMENT}.icanbwell.com/fhir/`	b.well MCP server endpoint (`client-sandbox`)
`authorization_token`	User access token	Bearer token for user authentication

Code Example: Bearer Token Authentication

Use this approach when you have a user access token from b.well's OAuth 2.0 token exchange

import anthropic

client = anthropic.Anthropic(api_key="{insert your anthropic key here}")

person_id = "{insert person id here}"
user_token = "{insert your user token here}"
mcp_fhir_agent_url = "https://mcpfhiragent.client-sandbox.icanbwell.com/fhir/"

response = client.beta.tools.messages.create(
    model="claude-sonnet-4-5",
    tools=[{
        "type": "url",
        "name": "bwell-mcp-fhir-agent",
        "url": mcp_fhir_agent_url,
        "authorization_token": user_token,
    }],
    messages=[
        {"role": "user", "content": f"Get Active Medications for person_id={person_id}"}
    ],
    betas=["mcp-client-2025-04-04"]
)

print(response.content)
