Frequently asked questions

1

What authentication methods are supported?

OAuth 2.1 with PKCE (for interactive clients like Claude.ai) and API key authentication (for programmatic access). Both require Descope as the identity platform.

2

How do I integrate with Claude.ai?

In Claude.ai settings, add a custom MCP integration with the server URL (e.g., `http://localhost:8081/stream`). Complete the OAuth flow when prompted to connect.

3

What environment variables are required?

You must set `DESCOPE_PROJECT_ID`, `DESCOPE_MANAGEMENT_KEY`, `NEO4J_URI`, `NEO4J_USERNAME`, `NEO4J_PASSWORD`, `OAUTH_CLIENT_ID`, `OAUTH_CLIENT_SECRET`, `OAUTH_REDIRECT_URI`, and `SESSION_SECRET`.

4

How can I deploy with Docker?

Use the pre-built Docker image `arturrenzenbrink/neo4j-fastmcp-server:latest` with environment variables for Descope, Neo4j, and session secret, or use the included `docker-compose.yml`.

5

What testing tools are available?

You can use the MCP Inspector (`npx @modelcontextprotocol/inspector`) or test with cURL by sending requests to `http://localhost:8081/stream` using either an OAuth bearer token or an API key header.
