Pick Chroma MCP Server if you need the broadest set of tools.

Pick Memory (Knowledge Graph) if you prefer the more popular, battle-tested option, and you want zero-setup with no API key.

Add Chroma MCP Server

Install / run

uvx chroma-mcp --client-type persistent --data-dir /absolute/path/to/data

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "chroma-mcp-server": {
      "command": "uvx",
      "args": [
        "chroma-mcp",
        "--client-type",
        "persistent",
        "--data-dir",
        "/absolute/path/to/data"
      ]
    }
  }
}

Requires `uv` (the Python package runner). Install it from https://docs.astral.sh/uv/ if `uvx` is not found.

Add Memory (Knowledge Graph)

Install / run

npx -y @modelcontextprotocol/server-memory

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "memory-knowledge-graph": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-memory"
      ],
      "env": {
        "MEMORY_FILE_PATH": "/absolute/path/to/memory.jsonl"
      }
    }
