Overview

Chroma MCP Server is a Model Context Protocol (MCP) server implementation that provides vector database capabilities through Chroma, enabling semantic document search, metadata filtering, and document management with persistent storage.

To use Chroma MCP Server, start the server using the command uv run chroma and interact with it using MCP tools to create, read, update, and delete documents or to perform semantic searches.

  • Semantic Search: Find documents based on meaning using Chroma's embeddings. - Metadata Filtering: Filter search results by metadata fields. - Content Filtering: Additional filtering based on document content. - Persistent Storage: Data persists in local directory between server restarts. - Comprehensive Error Handling: Clear messages for common errors. - Automatic Retry Logic: For transient failures.
  1. Managing academic papers and research documents.
  2. Implementing a semantic search engine for document retrieval.
  3. Storing and filtering documents based on metadata for various applications.

Use these steps to connect Chroma MCP Server in Cursor, Claude, VS Code, and other MCP-compatible apps. The same JSON appears in the Use with menu above for one-click copy.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "chroma-privetin": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-chroma-privetin"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "chroma-privetin": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-chroma-privetin"
      ]
    }
  }
}

Claude Code

Add this to your project's .mcp.json file. Claude Code will detect it automatically.

.mcp.json (project root)

{
  "mcpServers": {
    "chroma-privetin": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-chroma-privetin"
      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
  "servers": {
    "chroma-privetin": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-chroma-privetin"
      ]
    }
  }
}

Windsurf

Add this to your Windsurf MCP config file, then restart Windsurf.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "chroma-privetin": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-chroma-privetin"
      ]
    }
  }
}

Cline

Open Cline settings, navigate to MCP Servers, and add this server configuration.

Cline MCP Settings (via UI)

{
  "mcpServers": {
    "chroma-privetin": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-chroma-privetin"
      ]
    }
  }
}
