CKB

CKB is an MCP tool suite for AI coding that turns a codebase into a queryable knowledge system. It analyzes and explains code rather than modifying it, and the page frames it around impact analysis, ownership, dead code, security scanning, and architecture work.

Its listed capabilities include code review with 20 structural PR checks, code navigation for finding things instantly, impact analysis that shows blast radius, affected files, tests, and risk scores, security scanning for exposed secrets, dead code detection for unused code, and code ownership for determining who owns what. It also includes compound operations intended to reduce tool calls by 70%, compliance audit mapping findings to 20 regulations, and CI/CD integration for automating a pipeline. The page says the suite offers more than 90 tools across nine categories, including code navigation, impact analysis, security scanning, ownership and review, dead code detection, federation, architecture intelligence, and CI/CD integration.

CKB works through CLI, HTTP API, daemon mode, and any MCP client. It is described as working with GitHub, GitLab, and Bitbucket, and the quick start section says it can be set up in under a minute. The site also says it works with AI coding tools including Claude Code, Cursor, Windsurf, VS Code, OpenCode, Grok, and Claude Desktop.

Pricing is listed as free for personal use, open source, and startups under $25k revenue, with commercial licensing required above that threshold. The pricing section also lists a Personal tier with CLI and HTTP API access, unlimited repositories, and community support; a Team tier at $9 per user per month for commercial teams up to 50 developers; and an Enterprise tier at $29 per user per month for large organizations. The footer names SimplyLiz.
