feat(plaud): add Plaud MCP plugin

[rshah2020]

Adds third_party/plaud, a plugin for Plaud's official MCP server (@plaud-ai/mcp), and registers it in marketplace.json and the root README.

MCP

Plaud does not publish a hosted MCP endpoint for Cursor. The official server is local stdio via npx, matching their docs:

{
  "mcpServers": {
    "plaud": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@plaud-ai/mcp@latest"]
    }
  }
}

Auth is browser OAuth through the server's login tool — no API keys, client secrets, or plugin variables. Requires Node.js ≥ 20 and npx on PATH.

Scaffold

Mirrors existing third_party/ plugins (plugin.json, mcp.json, README.md, CHANGELOG.md, LICENSE, assets/logo.svg). Logo is a simple placeholder SVG; swap for Plaud's official mark if preferred.

Validation

node scripts/validate-plugins.mjs passed.

No secrets bundled.

Note

Low Risk
Adds marketplace metadata and a stdio MCP wrapper only; no bundled credentials or changes to core app logic.

Overview
Adds a new Plaud Cursor integration so agents can search recordings, transcripts, notes, and action items via Plaud’s official MCP server.

The plugin lives under third_party/plaud with the usual manifest (plugin.json), mcp.json, docs, changelog, license, and placeholder logo. MCP is configured as local stdio through npx -y @plaud-ai/mcp@latest (not a hosted endpoint). Auth is browser OAuth via the server’s login tool—no plugin API keys or secrets.

Plaud is registered in .cursor-plugin/marketplace.json and the root README integrations table alongside other meeting/transcript plugins (e.g. Fathom, Otter).
