Codegraph
Query a semantic code graph for callers, blast radius, complexity, and dead code before you merge risky changes.
Overview
Codegraph is a MCP server for the Ship phase that provides 31 semantic graph tools for callers, impact, complexity, and unused code across 15 languages.
What is this MCP server?
- 31 graph tools for callers, impact, complexity, and unused code
- Semantic code graph across 15 programming languages
- Stdio MCP via @memoryx/codegraph-mcp npm package 0.9.2
- Surfaces change blast radius for agent-driven review
- Pairs with Claude Code or Cursor for navigation without manual ripgrep tours
- 31 MCP tools
- 15 supported languages
- Server package version 0.9.2
What problem does it solve?
Agents and solo devs lack fast, structured answers about call graphs and change impact across large or unfamiliar codebases.
Who is it for?
Builders doing agent-assisted code review or refactors on multi-language repos who need graph queries beyond text search.
Skip if: Greenfield prototypes with almost no code history or teams that only need linting without structural analysis.
What do I get? / Deliverables
After you connect Codegraph, your agent can query semantic relationships and review risk before merges or refactors.
- 31 graph query tools callable from the agent
- Cross-language semantic navigation for review and refactors
Recommended MCP Servers
Journey fit
Impact and complexity analysis is canonical on the review shelf in Ship, but the same graph aids Build refactors and Operate fixes. Callers, impact, and unused-code tools mirror pre-merge review questions agents answer during code review.
How it compares
Semantic graph MCP for review, not a cloud deploy or monitoring dashboard.
Common Questions / FAQ
Who is Codegraph for?
Solo developers and small teams using AI agents who need caller, impact, and complexity intelligence across a real codebase.
When should I use Codegraph?
Use it during Ship review before merging, and during Build or Operate when tracing dependencies or dead code.
How do I add Codegraph to my agent?
Add the @memoryx/codegraph-mcp stdio server from npm to your MCP config following the codegraph-ai repository setup.
