Buildkite MCP Server

Category: Cloud & DevOps MCP Servers
Brand: Buildkite
Website: https://buildkite.com/docs/apis/mcp-server
MCP Endpoint: https://mcp.buildkite.com/mcp

An open-source Model Context Protocol (MCP) server that exposes Buildkite CI/CD data (pipelines, builds, jobs, and Test Engine test data) to AI tools, agents, and editors via the Buildkite REST API. It supports both remote (hosted) and local (self-hosted) modes and uses OAuth 2.1 for secure access in the remote configuration.

Features

General Capabilities

• Implements the Model Context Protocol (MCP) to connect AI tools, agents, and editors to Buildkite.
• Exposes Buildkite product data, including:
  • Pipelines
  • Builds
  • Jobs
  • Test Engine test data
• Built on top of the Buildkite REST API.
• Open-source server implementation (available on GitHub).
• Provides a set of MCP tools for interacting with Buildkite resources (see tools documentation for full list).

Server Types

Remote MCP Server (Hosted by Buildkite)

• Hosted by Buildkite at https://mcp.buildkite.com/mcp.
• Recommended option for most users and interactive AI tools.
• Typically used from AI tools you interact with directly via a prompt.
• Automatically updated by Buildkite, providing new features and fixes without local installs or upgrades.

Authentication & Authorization (Remote)

• Uses OAuth 2.1 via your Buildkite user account.
• Buildkite issues short-lived OAuth access tokens that:
  • Represent your user account.
  • Include pre-set read and write permission scopes for the server.
• Token lifetimes:
  • Access tokens valid for 12 hours.
  • Refresh tokens valid for 7 days.
• OAuth flow runs after configuring your AI tool to connect to the remote MCP server.

Security & Convenience

• No API access token configuration required (reduces risk of token leakage).
• Suitable for personal and interactive usage with AI tools.

Limitations

• Not suitable for automated workflows where:
  • A fixed MCP server version is required.
  • Strict version reproducibility and consistency are important.

Read-only Remote MCP Server

• Separate remote variant offering read-only access.
• Intended for users who prefer not to grant write permissions while using the MCP server.

Local MCP Server (Self-hosted)

• Run the MCP server locally in your own environment.
• Requires installation of the MCP server package.
• Requires manual configuration of a Buildkite API access token for authentication.
• Appropriate when you need:
  • Control over the specific server version.
  • Use in automated workflows and CI automation.
  • Tighter control over environment and upgrade cadence.

Local Setup Steps (Conceptual)

• Install and run the Buildkite MCP server locally.
• Configure a Buildkite API access token for the server.
• Configure your AI tools to connect to the local MCP endpoint.

Integration with AI Tools

• Both remote and local modes can be used by MCP-compatible tools, editors, and agents.
• Separate configuration flows described for:
  • Remote MCP server integration.
  • Local MCP server integration.

Use Cases

• Query and explore Buildkite pipelines and builds from AI-powered chat or editor integrations.
• Inspect jobs and test data (including Test Engine results) via AI tools.
• Automate or assist CI/CD tasks interactively through MCP-compatible agents.
• Read-only observability into Buildkite resources when using the dedicated read-only remote server.
