Skills & MCP | Launch Week 03, Day 4
Bring cubic into your IDE with MCP and agent skills. Review code before pushing, use codebase context, and resolve GitHub feedback from your coding agent.
Santiago Orozco
cubic has always reviewed your code after you pushed it, in GitHub.
Today, we bring its power into your IDE.
How it works
With the new MCP and skills, your local coding agent can directly interact with cubic.
Pull architectural context from your cubic wiki before you plan. Surface your team's coding standards while you write. Run a local AI code review before you push. Fetch and address GitHub review comments without leaving your editor.
One install sets up every supported coding agent it finds on your machine, including Claude Code, Codex, Cursor, Gemini CLI, OpenCode, Droid and Pi.

MCP tools
Your coding agent can now call cubic directly. Tools include the following, and the MCP server docs list them all:
Reviews Comments: pull review comments without leaving your editor
Wiki: query AI-generated documentation about your codebase architecture
Review Learnings: surface your team's coding patterns and conventions
Codebase Scans: check scan results and drill into findings
These are not summaries. They are the same tools cubic uses internally, exposed as MCP endpoints your agent calls on demand.
Skills that give your agent superpowers
Skills trigger based on what you are doing. You do not need to remember commands or configure triggers. Our guide to Claude Code skills explains how skills load and how to write your own, and our practical guide to using Claude Code covers the rest of the setup.
Skill | Triggers when | What it does |
|---|---|---|
check-pr-comments | You mention PR comments or review feedback | Fetches unresolved cubic comments, fixes the real issues, commits, pushes, and resolves threads |
run-review | You say "review my code" or want a pre-commit check | Runs a local cubic review via CLI and surfaces issues by priority |
cubic-loop | You say "loop until clean" or want to polish before merge | Reviews, fixes, and re-reviews in a loop until clean or max iterations |
codebase-context | You ask how something works | Queries cubic's AI-generated wiki for architectural context |
review-patterns | You are writing or reviewing code | Pulls your team's learned conventions so your code matches on the first try |
