TL;DR – what lives here?

A monorepo that ships the Perplexity MCP runtime two ways:

• perplexity-vscode – native VS Code extension with an embedded MCP daemon, webview dashboard, and auto‑config for 15+ MCP‑capable IDEs.[^ver]
• perplexity-user-mcp – the same MCP server as a standalone npm package for Cursor, Claude Desktop, Claude Code, Windsurf, Cline, Amp, Codex CLI, and any other MCP client that talks stdio.

Both wrap a long‑lived patchright browser session against your existing Perplexity account, so the tools consume your logged‑in plan (Free / Pro / Max) instead of an API key.[^runtime]

[^ver]: See CHANGELOG.md for current version and release notes. [^runtime]: Browser and profile details: packages/mcp-server and Architecture notes.

Who should use what?

<table> <thead> <tr> <th align="left">You want to…</th> <th align="left">Use</th> <th align="left">How</th> </tr> </thead> <tbody> <tr> <td>Use Perplexity inside VS Code with a dashboard, login flows, and auto‑config for other IDEs.</td> <td><strong><code>perplexity-vscode</code></strong> (extension)</td> <td>Install the VSIX or from Marketplace, run <code>Perplexity: Login</code>, optionally enable auto‑config.</td> </tr> <tr> <td>Run the MCP server standalone for Cursor / Claude Desktop / Windsurf / Cline / Amp / Codex CLI.</td> <td><strong><code>perplexity-user-mcp</code></strong> (npm CLI)</td> <td><code>npm install -g perplexity-user-mcp</code> or <code>npx perplexity-user-mcp</code>, point your MCP client at it.</td> </tr> <tr> <td>Keep a long‑lived HTTP MCP daemon with tunnels (Cloudflare Quick Tunnels / ngrok).</td> <td><strong>Daemon mode</strong> (mcp‑server <code>daemon/</code>)</td> <td>Use the daemon entrypoint & tunnel providers under <code>packages/mcp-server/src/daemon/</code>.</td> </tr> </tbody> </table>

---

Repo shape

Four npm workspaces under <a href="./packages/">packages/</a>. Almost every aggregate task builds shared first because the extension host and the webview both import its contracts from source.[^shape]

• packages/shared – message contracts, IdeTarget / DashboardState types, and the PERPLEXITY_RULES_SECTION_START/END markers used by auto‑config.
• packages/mcp-server – Perplexity MCP runtime. Ships standalone as perplexity-user-mcp and is bundled into the extension’s dist/mcp/server.mjs (ESM only).
• packages/webview – React 19 + Vite + Tailwind v4 + zustand dashboard. Built assets copied into packages/extension/media/webview/.
• packages/extension – VS Code extension host (CommonJS via tsup, target: node20). Registers the bundled MCP server via mcpServerDefinitionProviders, owns the webview, auto‑config, and the embedded daemon.

[^shape]: See tsconfig.base.json and vitest.config.ts for workspace wiring and test globs.

Quick start

Prerequisites:

• Node.js 20+
• npm (workspaces enabled)
• A Perplexity account (Free / Pro / Max)

git clone https://github.com/Automations-Project/VSCode-Perplexity-MCP.git
cd VSCode-Perplexity-MCP

npm install
npm run build          # shared → mcp-server → webview → extension (in that order)
npm test               # vitest across all packages
npm run package:vsix   # produces packages/extension/perplexity-vscode-<version>.vsix

Install the unpacked extension into VS Code:

code --install-extension packages/extension/perplexity-vscode-<version>.vsix

Build order matters. packages/shared must build before the other three. The root scripts enforce this; keep that invariant when adding new scripts.

Browser support matrix

The MCP server automates a real Chromium browser via patchright to survive Cloudflare and serve Perplexity.[^browser]

<table> <thead> <tr> <th align="left">Priority</th> <th align="left">Runtime</th> <th align="left">Env hints</th> <th align="left">Notes</th> </tr> </thead> <tbody> <tr> <td>#1</td> <td><strong>Google Chrome</strong></td> <td><code>PERPLEXITY_BROWSER_CHANNEL=chrome</code></td> <td>Recommended, best Cloudflare compatibility.</td> </tr> <tr> <td>#2</td> <td><strong>Microsoft Edge</strong></td> <td><code>PERPLEXITY_BROWSER_CHANNEL=msedge</code></td> <td>All three platforms, works like Chrome.</td> </tr> <tr> <td>#3</td> <td><strong>System Chromium</strong></td> <td><code>PERPLEXITY_BROWSER_CHANNEL=chromium</code></td> <td>Mainly Linux; good for headless servers.</td> </tr> <tr> <td>#4</td> <td><strong>Brave</strong></td> <td>auto‑detected</td> <td>Chromium‑based; works with no special flags.</td> </tr> <tr> <td>#5</td> <td><strong>Patchright’s bundled Chromium</strong></td> <td> <code>npx patchright install chromium</code><br> then auto‑detected </td> <td>Fallback when nothing else is present.</td> </tr> </tbody> </table>

Extra overrides:

• PERPLEXITY_BROWSER_PATH – absolute browser executable path (wins over detection).
• PERPLEXITY_CHROME_PATH – legacy alias for PERPLEXITY_BROWSER_PATH.
• PERPLEXITY_CONFIG_DIR – overrides ~/.perplexity-mcp (profiles, vault, daemon state).

---

First run, profiles, and the vault

Perplexity serves a Cloudflare Turnstile on first run; the server opens a headed browser for you to log in, then caches cf_clearance + session in ~/.perplexity-mcp/.[^login]

• Profiles live under ~/.perplexity-mcp/profiles/<name>/.
• Cookies are encrypted into vault.enc (keytar with passphrase fallback).
• Any process that mutates profile state touches a .reinit sentinel, which running MCP servers watch and hot‑reload from (no restart required).

Delete ~/.perplexity-mcp/ to start over completely, or use PERPLEXITY_HEADLESS_ONLY=1 once a valid clearance is cached.

---

Supported IDEs / MCP clients

Auto‑config writes MCP configs and rulesets for 15+ IDEs and agents; the same server also runs everywhere else.[^ide]

<table> <thead> <tr> <th align="left">Client</th> <th align="left">How it’s wired</th> <th align="left">Config artifact</th> </tr> </thead> <tbody> <tr> <td><strong>VS Code</strong></td> <td>Native extension, embedded daemon, webview dashboard.</td> <td><code>settings.json</code>, <code>Perplexity: Login</code>, agent MCP config.</td> </tr> <tr> <td><strong>Cursor</strong></td> <td>Auto‑written MCP settings + rules section.</td> <td><code>.cursor/rules/.mdc</code>, <code>mcp.json</code>.</td> </tr> <tr> <td><strong>Claude Desktop / Claude Code</strong></td> <td>Config + rules docs, upsert between markers.</td> <td><code>claude_desktop_config.json</code>, <code>CLAUDE.md</code>.</td> </tr> <tr> <td><strong>Windsurf, Cline, Amp, Codex CLI</strong></td> <td>MCP config and rules files per target.</td> <td><code>mcp_config.json</code>, <code>.rules</code>, <code>.github/instructions/</code>, etc.</td> </tr> </tbody> </table>

Auto‑config uses IDE_METADATA in packages/shared/src/constants.ts and upserts PERPLEXITY-MCP-START / PERPLEXITY-MCP-END sections without touching hand‑written content.

Commands

All commands run from the repo root.

npm install

npm run build          # shared → mcp-server → webview → extension
npm run typecheck      # tsc --noEmit across all four packages
npm test               # builds shared, then runs vitest
npm run test:coverage  # vitest with v8 coverage; enforces per-file thresholds
npm run package:vsix   # full build + vendored deps + vsce package

npm run dev:webview    # Vite dev server for dashboard
npm run dev:extension  # tsup --watch for extension host
npm run clean          # rm dist + media/webview across packages

Single‑file / single‑test runs:

npx vitest run packages/mcp-server/test/redact.test.js
npx vitest run packages/extension/tests/auth-manager.login.test.ts
npx vitest run -t "resolves .reinit sentinel"

Coverage thresholds are enforced: e.g., redact.js / vault.js ≥ 95%, profiles.js / cli.js ≥ 85%.

Architecture notes

A few cross‑cutting pieces that matter:

• Bundled MCP with curated externals.
  packages/extension/package.json build:mcp tsups packages/mcp-server/src/index.ts into dist/mcp/server.mjs, renames index.mjs → server.mjs, and copies the mcp‑server package.json next to it. Externals (patchright, got-scraping, tough-cookie, gray-matter, express, @ngrok/ngrok, helmet, keytar, …) are deliberately left out of the bundle and vendored into dist/node_modules/ by packages/extension/scripts/prepare-package-deps.mjs.

• Daemon + pluggable tunnels.
  packages/mcp-server/src/daemon/ runs a long‑lived HTTP MCP server with OAuth 2.1 (via @modelcontextprotocol/sdk’s mcpAuthRouter) and pluggable tunnels under daemon/tunnel-providers/ (cf-quick and ngrok). Daemon state lives in <configDir>/daemon.lock, daemon.token, tunnel-settings.json, and ngrok.json.

• Browser detection & download manager.
  packages/extension/src/browser/browser-detect.ts probes Chrome → Edge → system Chromium → Brave → patchright’s Chromium, with BrowserDownloadManager managing patchright install chromium into VS Code’s globalStorage and AuthManager syncing env to the detached daemon.
