Harness
Trigger pipeline insight and Harness API actions from your agent when you are pushing releases through CI/CD.
Overview
Harness MCP Server is a MCP server for the Ship phase that gives coding agents Harness CI/CD API access over stdio with API key authentication.
What is this MCP server?
- Harness MCP server v0.1.0 on PyPI (harness-mcp-server) with stdio transport and uvx launch
- HARNESS_API_KEY required; HARNESS_API_URL optional for SaaS or self-hosted endpoints
- Exposes Harness API integration to Claude Code, Cursor, Codex, and Windsurf
- Supports indie teams already standardized on Harness pipelines instead of bespoke deploy scripts
- Repository: github.com/asklokesh/harness-mcp-server with MCP server schema
- Server version 0.1.0
- stdio transport; PyPI identifier harness-mcp-server
- Required HARNESS_API_KEY; optional HARNESS_API_URL
What problem does it solve?
Checking Harness pipeline status from the portal while fixing code splits attention right when you are trying to ship.
Who is it for?
Teams on Harness CD who want agent-assisted pipeline visibility and API-driven delivery steps.
Skip if: GitHub Actions-only shops with no Harness account, or builders who need MCP tools without any CI/CD platform API key.
What do I get? / Deliverables
After MCP registration, your agent can call Harness APIs in the same workflow where you merge, fix, and release.
- Registered Harness MCP stdio server in agent config
- API-key-authenticated Harness control-plane access from chat
- Configurable endpoint via HARNESS_API_URL when needed
Recommended MCP Servers
Journey fit
Harness is a delivery control plane; the MCP server matters most in Ship when you are validating pipelines and getting builds out the door. Launch subphase covers release automation, deployment gates, and last-mile delivery orchestration Harness users depend on.
How it compares
Harness DevOps API MCP connector, not a ship checklist or automated test runner skill.
Common Questions / FAQ
Who is Harness MCP Server for?
Developers using Harness pipelines who want MCP-enabled agents to interact with Harness APIs from their editor.
When should I use Harness MCP Server?
Use it during Ship launch work when you need pipeline or deployment context while coding or reviewing a release.
How do I add Harness MCP Server to my agent?
Add stdio MCP config for uvx harness-mcp-server, set HARNESS_API_KEY and optional HARNESS_API_URL, then restart your MCP client.
