CircleCI Automation via Rube MCP

Automate CircleCI CI/CD operations through Composio's CircleCI toolkit via Rube MCP.

Toolkit docs: composio.dev/toolkits/circleci

Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active CircleCI connection via RUBE_MANAGE_CONNECTIONS with toolkit circleci
• Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed, just add the endpoint and it works.

1. Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
2. Call RUBE_MANAGE_CONNECTIONS with toolkit circleci
3. If connection is not ACTIVE, follow the returned auth link to complete CircleCI authentication
4. Confirm connection status shows ACTIVE before running any workflows

Core Workflows

1. Trigger a Pipeline

When to use: User wants to start a new CI/CD pipeline run

Tool sequence:

1. CIRCLECI_TRIGGER_PIPELINE - Trigger a new pipeline on a project [Required]
2. CIRCLECI_LIST_WORKFLOWS_BY_PIPELINE_ID - Monitor resulting workflows [Optional]

Key parameters:

• project_slug: Project identifier in format gh/org/repo or bb/org/repo
• branch: Git branch to run the pipeline on
• tag: Git tag to run the pipeline on (mutually exclusive with branch)
• parameters: Pipeline parameter key-value pairs

Pitfalls:

• project_slug format is {vcs}/{org}/{repo} (e.g., gh/myorg/myrepo)
• branch and tag are mutually exclusive; providing both causes an error
• Pipeline parameters must match those defined in .circleci/config.yml
• Triggering returns a pipeline ID; workflows start asynchronously

2. Monitor Pipelines and Workflows

When to use: User wants to check the status of pipelines or workflows
