This workflow streamlines the management and triggering of CircleCI pipelines through an n8n integration using MCP (Model Checking Protocol) Server. It provides a centralized way to get specific pipeline details, retrieve multiple pipelines, and trigger new pipeline runs, all via a webhook trigger. The setup allows automation for development teams to effortlessly monitor and initiate CircleCI workflows from external or AI-driven sources.

The workflow begins with a webhook trigger node named ‘CircleCI Tool MCP Server,’ designed to listen for incoming requests from external systems, including AI agents. Once activated, the workflow supports three main operations:

1. **Get a pipeline** – Retrieves detailed information about a specific pipeline by using parameters such as version control system, project slug, and pipeline number, which can be dynamically supplied via AI expressions.

2. **Get many pipelines** – Fetches a list of recent pipelines from a specified project, with options to limit the number of results and specify filters.

3. **Trigger a pipeline** – Initiates a new pipeline run based on provided project information.

Each node is configured with credential management for secure API interactions with CircleCI. The workflow’s design ensures minimal setup effort, with AI-powered parameter population and built-in error handling. This automation is particularly useful for development teams seeking to integrate CircleCI pipelines into larger CI/CD dashboards, automate build triggers, or embed pipeline controls into custom applications or chatbots.
