Elasticsearch

1. Obtain Your Elasticsearch Host URL

   • Identify the URL of your Elasticsearch instance (for example, https://your-es-instance.com).

2. Obtain an API Key or Username/Password

   • You can authenticate via API key (recommended) or via username and password.
   • For API key:
     1. Log into your Elasticsearch/Kibana admin interface.
     2. Go to “Management” > “Security” > “API Keys”.
     3. Click “Create API Key”, provide a name and (optionally) permissions.
     4. Save the generated API key securely—this is your ES_API_KEY.
   • For username/password:
     • Use your Elasticsearch user credentials (ES_USERNAME and ES_PASSWORD).

3. Add Environment Variables in FastMCP

   • Click the “Install Now” button to start adding your environment variables via the FastMCP connection interface.
   • In the interface, provide the following:
     • ES_HOST: Paste your Elasticsearch instance URL.
     • ES_API_KEY: Paste your API Key (if using API Key authentication).
     • OR, if using username/password:
       • ES_USERNAME: Your username.
       • ES_PASSWORD: Your password.
     • (Optional) ES_CA_CERT: Path to custom CA certificate for SSL/TLS, if required by your setup.

4. Save and Connect

   • After filling in all required values, save your configuration in the FastMCP interface.
   • Your MCP Client can now connect and interact with your Elasticsearch cluster.

Note: You must provide either an API key or both username and password for authentication—not both at the same time.
