PluginStack MCP server

Search PluginStack, a free, hand-checked directory of MCP servers, AI plugins and agent tools, from inside Claude, Cursor, VS Code, Codex or any other MCP client.

Ask things like "find me an MCP server for Postgres" or "how do I add Playwright MCP to Codex?" and get short answers with copy-paste install config and a link to the full PluginStack page.

• Free and open source (MIT). No account, no API key, no tracking.

• Read-only. It only reads PluginStack's own public listings and guides.

• Works offline: if the site can't be reached it falls back to a snapshot bundled with the package.

Tools

Every response ends with a link back to the canonical page on pluginstackai.com.

Related MCP server: remoteopenclaw-mcp

Install

Requires Node.js 18 or newer. The server runs with npx, so there is nothing else to install.

Claude Code

claude mcp add --transport stdio pluginstack -- npx -y pluginstack-mcp

Run /mcp inside Claude Code to check it connected.

Claude Desktop

Settings → Developer → Edit Config, then add to claude_desktop_config.json:

{
  "mcpServers": {
    "pluginstack": {
      "command": "npx",
      "args": ["-y", "pluginstack-mcp"]
    }
  }
}

Fully quit and reopen Claude Desktop. (A one-click .mcpb bundle is also available on the releases page.)

Cursor

Add to .cursor/mcp.json in a project, or ~/.cursor/mcp.json for all projects:

{
  "mcpServers": {
    "pluginstack": {
      "command": "npx",
      "args": ["-y", "pluginstack-mcp"]
    }
  }
}

VS Code

Add to .vscode/mcp.json (note the top-level servers key):

{
  "servers": {
    "pluginstack": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "pluginstack-mcp"]
    }
  }
}

Codex

codex mcp add pluginstack -- npx -y pluginstack-mcp

Or in ~/.codex/config.toml:

[mcp_servers.pluginstack]
command = "npx"
args = ["-y", "pluginstack-mcp"]

Windows

If you see spawn npx ENOENT, wrap the command in cmd /c: use "command": "cmd" and "args": ["/c", "npx", "-y", "pluginstack-mcp"]. See Fix "spawn npx ENOENT" for MCP servers on Windows.

Example prompts

• "Use PluginStack to find an MCP server that lets Claude control a browser."

• "What MCP servers does PluginStack list for databases? Give me the install config for Cursor."

• "How do I add the Context7 MCP server to Codex?"

• "List PluginStack's categories."

• "I'm getting MCP error -32000 Connection closed. Find the PluginStack guide and walk me through it."

• "Compare the coding agents on PluginStack and tell me which are open source."

Settings (optional)

How it works

The server fetches PluginStack's public /directory.json (the same data as the website) and caches it for an hour. If that fails it uses the copy in data/directory.json, and says so in its answers. It sends no data about you or your conversations; the only network request is that one GET.

Development

npm install
npm test                      # build, then call every tool through the official MCP SDK client
npm run snapshot              # refresh data/directory.json from the live site
npm run validate:server-json  # check server.json against the MCP Registry schema
npm run bundle                # build pluginstack-mcp.mcpb (Claude Desktop / Smithery)
npx @modelcontextprotocol/inspector node dist/index.js
