Setup steps

Install each MCP using the combined config below
Fill in required env vars for authenticated servers
Restart your MCP client (Cursor / Claude / VS Code)
Ask the agent to confirm tools are available

Once set up, try

Confirm all MCPs in Local dev loop are connected and list available tools
Walk me through a first workflow using Local dev loop
What env vars do I still need for Local dev loop?

Share this stack

Set up with your agent

Paste into Cursor, Claude, or any agent that can run multi-step MCP setup.

Install the Averlo stack "Local dev loop" (Filesystem MCP, Memory MCP, Playwright MCP, Fetch MCP) for Cursor.
1. For each server, read its README if install fails.
2. Merge this combined config:
{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "/path/to/allowed/dir"
      ]
    },
    "memory": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-memory"
      ]
    },
    "playwright": {
      "command": "npx",
      "args": [
        "@playwright/mcp@latest"
      ]
    },
    "fetch": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-fetch"
      ]
    }
  }
}
3. Collect any required API keys from the user; do not invent secrets.
4. Smoke-test each server.
