Kai
Ask your agent for call graphs, dependency maps, and blast-radius analysis before you merge risky changes.
Overview
Kai is a MCP server for the Ship phase that provides semantic code intelligence—call graphs, dependencies, impact analysis, and test coverage—over stdio MCP.
What is this MCP server?
- Semantic code intelligence over MCP (npm package kai-mcp)
- Call graphs and dependency relationships for navigation and reasoning
- Impact analysis for change blast radius
- Test coverage signals aligned with code structure
- stdio MCP server version 0.9.6 from kailayerhq/kai
- npm package identifier kai-mcp
- stdio MCP transport
Community signal: 18 GitHub stars.
What problem does it solve?
Agents hallucinate refactors when they cannot see real call chains, dependency edges, or coverage holes in your repo.
Who is it for?
Solo builders doing backend refactors or pre-merge review with an MCP-enabled coding agent.
Skip if: Greenfield repos with almost no code yet, where graph and coverage tooling has little to analyze.
What do I get? / Deliverables
After installing Kai, your agent can query structured graphs and impact signals before you approve risky edits.
- Agent-queryable call graphs and dependency views
- Impact analysis context for proposed changes
- Coverage-aligned answers for review and test planning
Recommended MCP Servers
Journey fit
Semantic code intelligence pays off right before you ship, when you need confidence about impact and coverage—not when you are still ideating. Impact analysis, dependencies, and test coverage are review-time questions that prevent bad merges.
How it compares
Semantic code-intelligence MCP, not a hosted CI dashboard or generic web-search skill.
Common Questions / FAQ
Who is Kai for?
Kai is for developers who want MCP-backed call graphs, dependencies, impact analysis, and coverage insight while pair-programming with agents.
When should I use Kai?
Use Kai before merging non-trivial changes, during refactors, or whenever you need dependency and impact facts from the codebase.
How do I add Kai to my agent?
Register the stdio MCP server for npm identifier kai-mcp (version 0.9.6), point it at your project per Kai docs, and reload MCP in Claude Code, Cursor, or Codex.
