Ars Contexta

by agenticnotetaking · agenticnotetaking/arscontexta

Tell it about your workflow; it designs a Markdown-backed second brain shaped for you — no templates, derived structure.

Ars Contexta uses a 2–4 turn conversation to derive the right knowledge architecture for you, then writes the folders, navigation, and skills. Backed by 249 research claims; emphasizes plain Markdown as source of truth.

      "command": "git",

        "https://github.com/agenticnotetaking/arscontexta"
      ],
      "_inferred": true

}

Open Claude Desktop → Settings → Developer → Edit Config. Restart after saving.

  }
}

Cursor uses the same mcpServers schema as Claude Desktop. Project config wins over global.

VS Code → Cline → MCP Servers → Edit

  "mcpServers": {
    "arscontexta": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/agenticnotetaking/arscontexta"
      ],
      "_inferred": true
    }
  }
}

Click the MCP Servers icon in the Cline sidebar, then "Edit Configuration".

~/.codeium/windsurf/mcp_config.json
{
  "mcpServers": {
    "arscontexta": {
      "command": "git",
      "args": [

      ],
      "_inferred": true
    }
  }
}

Same shape as Claude Desktop. Restart Windsurf to pick up changes.

~/.continue/config.json
{
  "mcpServers": [
    {
      "name": "arscontexta",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/agenticnotetaking/arscontexta"
      ]
    }
  ]
}

Continue uses an array of server objects rather than a map.

~/.config/zed/settings.json
{
  "context_servers": {
    "arscontexta": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/agenticnotetaking/arscontexta"
        ]
      }
    }
  }
}

Add to context_servers. Zed hot-reloads on save.

claude mcp add arscontexta -- git clone https://github.com/agenticnotetaking/arscontexta

One-liner. Verify with claude mcp list. Remove with claude mcp remove.
