MCP server for Harness API integration

VerifiedSTDIODesktop onlyCloud & InfrastructureDeveloper Tools

Overview

AI-generated overview

Local MCP server that connects an assistant to the Harness API for continuous delivery and cloud cost management.

What you can do
  • Access Harness platform APIs through a broad set of generated tools
  • Work with continuous delivery and cloud cost management resources
  • Authenticate against Harness using the configured API key
  • Rely on built-in rate limiting, retry logic and async calls
When to use it
Useful when you want an assistant to query or act on Harness CI/CD and cloud cost data from your own machine, rather than through the Harness web UI.
Requirements
Runs locally as a Python package (pip install harness-mcp-server, or uvx). Requires a Harness API key in HARNESS_API_KEY and optionally a custom endpoint in HARNESS_API_URL. Network access to the Harness API is needed.
Before you install
The server holds a Harness API key that can act on your Harness account; keep it out of shared configs. The README claims comprehensive API coverage, so tools may change or delete delivery and cost resources. No tool list is published, so review what it exposes before use.

Installation

In SourceWeft

  1. Open Harness in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Score

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
