Unofficial read-only MCP server exposing several Mercury banking organizations to one AI session.

Security Report

6.2
Moderate6.2Moderate Risk

This is a well-designed, security-conscious Gmail MCP server with excellent authentication controls, proper credential handling, and thoughtful defenses against prompt injection and account bleed. The code is clean, permissions match the purpose, and sensitive operations are protected by explicit safeguards (two-factor send arming, account verification, token encryption). Minor code quality observations exist but do not constitute security vulnerabilities. Package verification found 1 issue (1 critical, 0 high severity).

Personal AI Systems

Open-source templates, skills, and frameworks for using AI as a personal systems architect.

Built and maintained by Dima Kaleganov. AI builder, photographer, and animator on the weekends.

What's in here

MCP servers live in their own repositories and are linked from here.

  • personal-health-systems-coach/ — A complete system prompt template plus Claude Skill for building your own AI health coach with Claude Projects, ChatGPT GPTs, or any LLM with persistent context. Includes a vetted source library, failure modes, and clinical escalation rules.

  • multi-gmail-private-mcp/ — A self-hosted MCP server that gives Claude read, triage, and draft access to multiple Gmail / Google Workspace accounts at once (the official connector handles one). Drafts-only by default, no delete ever, per-account encrypted tokens, and a CLAUDE.md so Claude Code can walk you through your own setup.

  • mercury-multiorg-mcp — An unofficial, read-only MCP server that works across several Mercury banking organizations in one AI session; available on PyPI and in the official MCP Registry.

  • qbo-multicompany-mcp/ — Currently a build brief only (a CLAUDE.md design for a read-only multi-company QuickBooks Online MCP server); no code yet. It will move to its own repository when built.

Why this exists

The bottleneck on personal AI is not access to AI. It is the work of building the system prompt, source library, and operating rules that turn an AI into a useful specialist. This repo is where I publish what I have built so you can shortcut the same work.
