# Harness MCP

Vendor: Harness  
Category: developer-tools  
Auth: API_KEY  
Composio slug: `harness`

Harness Core CD APIs for managing pipelines, executions, services, environments, infrastructure, input sets, triggers, and templates.

## Verdict

The Harness MCP lets your team query deployment pipelines, environments, and execution history without leaving Switchy. @mention it to pull pipeline status across projects, check which services are deployed where, or audit recent runs. Engineers get instant visibility into CI/CD state during standups or incident reviews. DevOps leads can snapshot org-wide pipeline health for reports. Setup requires a Harness API key with read access to the projects you want to query. The MCP surfaces metadata and execution logs but doesn't trigger deployments or modify configurations.

## Tools

- **List Organizations** — List one page of Harness organizations accessible to the connected account, optionally filtered by identifier or search text.

- **List Projects** — List one page of Harness projects accessible to the connected account, optionally within an organization or filtered by module and search text.
