What is Claude Context?
Claude Context is an open-source MCP plugin from Zilliz that adds semantic code search to Claude Code and other AI coding agents. It indexes your codebase into a vector database and brings only the relevant code into the agent's context, so the agent finds code across millions of lines without many rounds of file discovery.
Zilliz pitches it as cost-effective for large codebases, since it avoids loading whole directories for every request. It needs a vector database (Milvus or a free Zilliz Cloud cluster) and an embedding provider such as OpenAI, works as an MCP server with Claude Code, Gemini CLI and other MCP clients, and also ships as a VS Code extension and npm packages.

Other coding tools in our directory. See all coding tools →
Trail Code
Context layer that makes Claude Code, Cursor, Codex and other coding agents faster and cheaper on large codebases.
SocratiCode
Codebase context engine for AI agents with hybrid semantic search, dependency graphs and impact analysis, available as MCP, plugin or skill.
Gemini MCP Tool
MCP server that lets Claude and other assistants call the Gemini CLI to analyze large files and codebases with its big context window.
Repowise
Codebase intelligence tool that indexes code, call graph, git history and docs locally and answers questions for you and your coding agent over MCP.
Semble
Fast code search for agents that uses far fewer tokens than grep and file reads.
Sphinx
Open-source Git hook for agent-assisted coding: before code your agent wrote is pushed to a protected branch, it reads the diff and quizzes you on what the change actually does when things go wrong, and only lets the push through once you answer correctly. Works with Claude Code, Codex, Cursor and OpenCode.
