Connect your saved prospects.

Optional AI connections require Prospect 1.5.0 or newer and a companion running on your computer. The 1.5.0 extension package is prepared; availability in the Chrome Web Store depends on Google review and publication.

Update through the Chrome Web Store

Keep your existing store installation. Chrome automatically downloads approved updates. Save edits and close all Prospect tabs and popups, or restart Chrome, to finish a downloaded update. You can also open chrome://extensions, enable Developer mode, and click Update. Version 1.5.0 adds Settings → Version & updates. Uninstalling removes local extension data; do not reinstall just to update. Local development copies use Reload and do not receive store updates.

1. Download and start the companion

Download Prospect MCP companion 1.5.0 (ZIP). Unzip it into a folder you will keep. Install Node.js 20.11 or newer from nodejs.org. Open Terminal in the unzipped folder and run:

npm ci
npm run mcp:setup
npm run mcp:bridge

Keep the last command running. The companion listens only on your computer (127.0.0.1). Its .prospect-mcp folder contains private connection files. The included mcp/README.md has full platform instructions. Chrome updates the extension separately; updating the companion currently requires downloading its new package and configuring that folder.

2. Choose what to share

Open .prospect-mcp/connection-code.txt locally and copy the code. In the extension, open Saved prospects → Settings → AI connections. Paste it into Connection code, choose all prospects or selected rows, leave quick notes off unless you want to share them, and click Connect & share. Confirm Sharing is on and the count. This is a local connection code, not an OpenAI key.

3. Connect your AI app

Claude Desktop: Open Settings → Developer → Edit Config. Merge the prospect entry from .prospect-mcp/claude-desktop.json into your existing mcpServers object, preserving other entries. Restart Claude.

Claude Code: Run the generated claude mcp add command from .prospect-mcp/client-commands.txt. Check with claude mcp list.

ChatGPT: Create a private tunnel associated with your ChatGPT workspace in OpenAI Platform. Follow the included commands and OpenAI’s Secure MCP Tunnel instructions. Use a restricted runtime credential with Tunnels Read and Use; enter it locally, never in a chat or in Prospect's connection-code box. In ChatGPT Plugins, add a custom MCP server, choose Tunnel, select that tunnel, and connect. Keep the tunnel running. Account tunnel access is required.

Claude in a web browser is not supported by this local version.

4. Test it

In another Terminal in the companion folder, run npm run mcp:check. In your connected AI app, ask: “Check my Prospect connection,” then “Find saved prospects with an email address, sorted by company name,” and “Read the first result with its sources and warnings.” Search and read tools cannot change records or send messages.

Sharing and privacy

Sharing is off by default. Only approved fields and rows are shared; quick notes are optional. New export fields need updated approval. The companion keeps its copy in memory and rejects data older than 150 seconds. Disconnect in Settings stops sharing and clears a reachable companion's copy. It does not erase data already returned to an AI conversation. Read the privacy policy.

Help

If Sharing is on but no data is available, keep Chrome, the bridge, and (for ChatGPT) the tunnel running; choose Sync now. Contact salesmapnh@gmail.com with the version and error message. Do not send credentials or private prospect lists.
