概要

What is Harness MCP Server?

Harness MCP Server is an MCP (Model Context Protocol) server that gives AI agents full access to the Harness.io platform through 11 consolidated tools and 212 resource types. It is built for developers and platform engineers who want to interact with Harness CI/CD, GitOps, Feature Flags, Cloud Cost Management, and more via natural language.

How to use Harness MCP Server?

Provide a Harness API key (PAT or SAT) and run the server with npx harness-mcp-v2@latest (no install required) or install globally via npm install -g harness-mcp-v2. Use stdio transport for local clients (Claude Desktop, Cursor, Devin Desktop) or HTTP transport for remote/shared deployments. Optionally set HARNESS_ORG and HARNESS_PROJECT for default scope; the agent can also discover orgs and projects dynamically.

FAQ from Harness MCP Server

What do I need to get started with Harness MCP Server?

You need a Harness API key (PAT or SAT) created from your Harness account profile. No other credentials are required—the account ID is auto‑extracted from the token.

What authentication methods does Harness MCP Server support?

For local/self‑hosted use, it uses HARNESS_API_KEY. The hosted MCP service uses Harness Platform OAuth (not HARNESS_API_KEY) and must be enabled by Harness Support.

Can I run Harness MCP Server remotely or in a shared deployment?

Yes, use the HTTP transport. Set HARNESS_MCP_AUTH_TOKEN for shared or remotely reachable deployments. The server exposes endpoints like /mcp (JSON‑RPC and SSE) and /health. Multi‑user mode allows each session to authenticate with its own Harness API key.

What Harness resources does the server cover?

It provides 37 default toolsets covering CI/CD, GitOps, Feature Flags, Cloud Cost Management, Security Testing, Chaos Engineering, Database DevOps, Internal Developer Portal, Software Supply Chain, Infrastructure as Code Management, Governance, Service Overrides, and Knowledge Graph. Opt‑in Ansible coverage is also available.

Where does my data live when using Harness MCP Server?

All data is fetched from the Harness.io platform API. The server does not store data; it only proxies requests to Harness endpoints using the credentials provided.
