What is the Harness MCP Server?
Connect your Harness.io platform to any AI agent and take full control of your software delivery and CI/CD pipelines through natural conversation.
What you can do
- Pipeline Management — List, inspect, and trigger pipeline executions across your projects.
- Execution Monitoring — Get real-time status updates and step details for active deployments.

How it works
- Subscribe to this server
- Enter your Harness API Key, Account ID, and Organization ID
- Start managing your CI/CD pipelines from Claude, Cursor, or any MCP-compatible client
No more manual navigating through complex DevOps dashboards. Your AI assistant acts as a dedicated Release Engineer or DevOps Coordinator.
Who is this for?
- DevOps Engineers — instantly retrieve pipeline statuses and trigger deployments without leaving the IDE.
- SREs — monitor execution failures and audit logs to maintain platform stability.
- Release Managers — automate the oversight of multiple projects and delivery pipelines.

Why CrewAI?
When paired with CrewAI, Harness becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Harness tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
- —
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the
mcpsparameter and agents auto-discover every available tool at runtime - —
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
- —
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

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 CrewAI discover and connect to MCP tools?
CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.
Can different agents in the same crew use different MCP servers?
Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.
What happens when an MCP tool call fails during a crew run?
CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.
Can CrewAI agents call multiple MCP tools in parallel?
CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.
Can I run CrewAI crews on a schedule (cron)?
Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
