How CGraph compares
Against every graded Web search MCP server, from our own scans and uptime checks. Updated after each scan run.
- Safety score
- 94/100
- higher than 96% of 3,470 Web search servers
- GitHub stars
- 2
- more than 70% of 1,786 Web search servers
Release history: 3 versions in the registry since 2026-10-14, latest 2026-10-21, typically one every 5 days.
Install CGraph in Claude Code, Cursor or VS Code
Runs npx -y cgraph-mcp on your machine. Read the scan report first; the gateway never runs local packages.

English · 简体中文
Scan a project · extract structure into a deterministic graph · query it in ~10 ms from a daemon, a thin client, or an MCP server.

Why CGraph?
Reading a large repo to answer "what calls this?" or "what breaks if I change it?" means loading dozens of files — and those answers aren't in any single file. They live in the relationships between files. CGraph precomputes them so you (and your AI agent) navigate by graph, not grep.
The pitch in one line: for a codebase too big to hold in your head, CGraph is the index that decides which code to read — ctags/"find all references", precomputed, centrality-ranked, and exposed over MCP.
Architecture
- cgraph — one-shot scan → portable disk exports (graph.json, graph.html, graph.svg, obsidian.md, cypher.txt, modules.mmd, modules.svg, design.mmd, design.md).
- graphd + cgraph-client — a resident per-project daemon with live file-watching; warm query / path / explain / impact / context in ~10 ms.
- cgraph-mcp — a Model Context Protocol server so agents navigate the graph directly.
The engine owns deterministic extraction, fragment validation, cache state, and local graph mutation; hosts own model choice and semantic enrichment.
Repository layout
Shortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
CGraph: common questions
- Is CGraph MCP server safe?
- Yes, by our scan: it is graded A (94/100). Read the CGraph safety report
- How do I install CGraph?
- It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
- Does CGraph need an API key?
- Not as far as the registry entry and our scan can tell: no credentials are declared or required.
- Is CGraph maintained?
- The last commit was 21 days ago (2026-10-14). The latest release is v0.9.7.
- What can I use instead of CGraph?
- Servers from other publishers that do the same job: Repomix MCP server, Arxiv MCP server and Socraticode MCP server.
- How does CGraph compare with other Web search MCP servers?
- safety score 94/100 (higher than 96% of 3,470 Web search servers); github stars 2 (more than 70% of 1,786 Web search servers). Full comparison.
