Anthropic's official Claude AI desktop application. Supports MCP servers to extend functionality.
brandononchain/gmail-mcp-agent
An open-source, plug-and-play toolkit for running personalized Gmail outreach and automated follow-ups — controllable over the Model Context Protocol (MCP) so you can drive it from any MCP-compatible client or run it as a 24/7 background service.
See repository
Setup steps are in the repository README.
Everything that's specific to a campaign — sender identity, subject lines, email copy, and your contact list — lives in config files and the templates/ directory. The code itself ships with no business, industry, or personal data baked in. Clone it, drop in your credentials, edit a few text files, and go.
CSV-driven outreach — send templated, personalized emails to a contact list.
Automated follow-up sequences — configurable timing (default: day 3 and day 7).
Response tracking — incremental, idempotent Gmail sync detects replies.
Keyword-based lead scoring — categorize replies as interested / not interested.
Auto-replies — optionally respond to interested leads automatically.
MCP server — start/stop/monitor the agent from any MCP client.
Runs anywhere — locally, via Docker, or as a systemd service.
