Frequently asked questions
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.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
