How do I find my Harness API Key?

Log in to Harness, go to **My Profile** (bottom left), and select **API Keys**. You can generate either a Personal API Key or use a Service Account Token from there.

Where can I find my Account ID and Org ID?

The Account ID is visible in your browser's URL when logged in (e.g., `account/XYZ123`). The Organization ID is typically found in the project settings or sidebar (default is often 'default').

Can I trigger a pipeline execution via this integration?

Yes! Use the `execute_pipeline` tool by providing the project ID and pipeline ID. Harness will initiate the workflow immediately.

Is the integration secure for managing secrets?

Absolutely. The integration only lists the metadata of your secrets (like names and identifiers) through your API key. Your credentials are encrypted and stored securely in the Vinkius Cloud.

Harness + Google ADK FAQ

Common questions about integrating Harness MCP Server with Google ADK.

How does Google ADK connect to MCP servers?

Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.

Can ADK agents use multiple MCP servers?

Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.

Which Gemini models work best with MCP tools?

Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
