Claude Context

Q: Does Claude Context need an API key?

Yes. It reads OPENAI_API_KEY and MILVUS_TOKEN from its environment, and OPENAI_API_KEY and MILVUS_TOKEN are secrets. Put the value in your client's config on your own machine, never in a shared file.

listing.about

Claude Context indexes a codebase into a Milvus or Zilliz Cloud vector database and lets an AI coding assistant search it with natural language. Code is split into chunks and embedded, so the assistant can pull relevant code from a large repository into context instead of loading whole directories.

It runs locally over stdio with npx. It needs an API key for an embedding provider (OpenAI by default, or VoyageAI, Gemini or Ollama) and a Milvus address and token, for example from Zilliz Cloud. Optional settings cover custom file extensions, ignore patterns, batch size and collection naming.

Claude Code

Run this in a terminal, in your project folder:

claude mcp add --transport stdio claude-context --env "OPENAI_API_KEY=<YOUR_OPENAI_API_KEY>" --env "MILVUS_TOKEN=<YOUR_MILVUS_TOKEN>" -- npx -y @zilliz/claude-context-mcp@latest

Start Claude Code and type /mcp. claude-context should show as connected.

Add --scope user to make it available in every project. Replace the placeholders with your own values.

Claude Desktop

Open Settings → Developer → Edit Config. It opens claude_desktop_config.json. Add:

claude_desktop_config.json

{
  "mcpServers": {
    "claude-context": {
      "command": "npx",
      "args": [
        "-y",
        "@zilliz/claude-context-mcp@latest"
      ],
      "env": {
        "OPENAI_API_KEY": "<YOUR_OPENAI_API_KEY>",
        "MILVUS_TOKEN": "<YOUR_MILVUS_TOKEN>"
      }
    }
  }
}

Save the file and restart Claude Desktop. Replace the placeholders with your own values.

Needs Node.js on your computer. The file lives in ~/Library/Application Support/Claude/ on macOS and %APPDATA%\Claude\ on Windows.

Cursor

Add to Cursor a11y.new_tab

Or add it by hand to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project):

mcp.json

{
  "mcpServers": {
    "claude-context": {
      "command": "npx",
      "args": [
        "-y",
        "@zilliz/claude-context-mcp@latest"
      ],
      "env": {
        "OPENAI_API_KEY": "<YOUR_OPENAI_API_KEY>",
        "MILVUS_TOKEN": "<YOUR_MILVUS_TOKEN>"
      }
    }
  }
}

Needs Node.js on your computer. Replace the placeholders with your own values.

VS Code

Add it to .vscode/mcp.json. VS Code asks for the secret the first time and stores it securely:

.vscode/mcp.json

{
  "servers": {
    "claude-context": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@zilliz/claude-context-mcp@latest"
      ],
      "env": {
        "OPENAI_API_KEY": "${input:openai-api-key}",
        "MILVUS_TOKEN": "${input:milvus-token}"
      }
    }
  },
  "inputs": [
    {
      "type": "promptString",
      "id": "openai-api-key",
      "description": "OPENAI_API_KEY",
      "password": true
    },
    {
      "type": "promptString",
      "id": "milvus-token",
      "description": "MILVUS_TOKEN",
      "password": true
    }
  ]
}

Needs Node.js on your computer.

Devin Desktop

Add it to ~/.config/devin/mcp_config.json (macOS and Linux) or %APPDATA%\devin\mcp_config.json (Windows):

mcp_config.json

{
  "mcpServers": {
    "claude-context": {
      "command": "npx",
      "args": [
        "-y",
        "@zilliz/claude-context-mcp@latest"
      ],
      "env": {
        "OPENAI_API_KEY": "<YOUR_OPENAI_API_KEY>",
        "MILVUS_TOKEN": "<YOUR_MILVUS_TOKEN>"
      }
    }
  }
}

Refresh the MCP server list in Cascade. Replace the placeholders with your own values.

Devin Desktop is the new name for Windsurf.

Codex

codex mcp add claude-context --env "OPENAI_API_KEY=<YOUR_OPENAI_API_KEY>" --env "MILVUS_TOKEN=<YOUR_MILVUS_TOKEN>" -- npx -y @zilliz/claude-context-mcp@latest

Or edit ~/.codex/config.toml directly:

config.toml

[mcp_servers.claude-context]
command = "npx"
args = ["-y", "@zilliz/claude-context-mcp@latest"]
env = { OPENAI_API_KEY = "<YOUR_OPENAI_API_KEY>", MILVUS_TOKEN = "<YOUR_MILVUS_TOKEN>" }

Needs Node.js on your computer. Replace the placeholders with your own values.

Gemini CLI

gemini mcp add -e "OPENAI_API_KEY=<YOUR_OPENAI_API_KEY>" -e "MILVUS_TOKEN=<YOUR_MILVUS_TOKEN>" claude-context npx -- -y @zilliz/claude-context-mcp@latest

This adds it to the current project. Add -s user to use it everywhere.

Any client

Most clients that start local servers accept this shape:

{
  "mcpServers": {
    "claude-context": {
      "command": "npx",
      "args": [
        "-y",
        "@zilliz/claude-context-mcp@latest"
      ],
      "env": {
        "OPENAI_API_KEY": "<YOUR_OPENAI_API_KEY>",
        "MILVUS_TOKEN": "<YOUR_MILVUS_TOKEN>"
      }
    }
  }
}

Zed puts servers under context_servers in its settings, with the same command, args and env fields.

Needs Node.js on your computer. Replace the placeholders with your own values.

listing.faq

Can I paste mcp.tc/i/claude-context into my MCP client?

No. Claude Context runs on your own computer, started by your client, so it has no web address to connect to. The quick link is the page to share; the install command is npx -y @zilliz/claude-context-mcp@latest.

Does Claude Context need an API key?

Yes. It reads OPENAI_API_KEY and MILVUS_TOKEN from its environment, and OPENAI_API_KEY and MILVUS_TOKEN are secrets. Put the value in your client's config on your own machine, never in a shared file.

Is Claude Context a remote or a local server?

Local. Your client starts it as a process on your computer with npx -y @zilliz/claude-context-mcp@latest, which needs Node.js.

What can Claude Context do?

You can index a codebase into Milvus or Zilliz Cloud, search code with natural language queries and choose OpenAI, VoyageAI, Gemini or Ollama embeddings.

Which clients can use it?

Any client that starts local servers: Claude Code, Claude Desktop, Cursor, VS Code, Devin Desktop, Codex, Gemini CLI, Zed and others. claude.ai and ChatGPT only connect to remote servers.

Who wrote this page?

mcp.tc's robot read Claude Context's public metadata (its package and repository pages), and an AI model drafted the text from it. A person reviews anything the checks can't confirm. The text can still be wrong, so if you spot a mistake, use Report this listing on this page.
