# Matthias Meyer

> Founder of StudioMeyer (an AI and design studio on Mallorca, where he has lived for 15 years). Builds open-source tools for the studio's stack: MCP servers, memory engines, agent frameworks and security layers, all MIT-licensed on github.com/studiomeyer-io.

## What lives here

This is the open-source side of my work. Studio (https://studiomeyer.io) is where I sell custom websites and AI systems, Academy (https://studiomeyer.academy) is where I teach, and here on matthiasmeyer.tech are the repos themselves: 42 public repositories, 6 concept deep dives and 7 books. I open-source them so other builders can read the architecture, study the trade-offs and lift what fits. Mostly TypeScript, with Rust and Python where they earn their keep.

This is the short version. The full description of every repo, every concept and every book is in /llms-full.txt.

## Cornerstone repos

The ones I would point a stranger at first.

- [Local Memory MCP](https://github.com/studiomeyer-io/local-memory-mcp): Persistent local memory for Claude, Cursor, Codex
- [Personal Suite MCP](https://github.com/studiomeyer-io/mcp-personal-suite): Local-first personal productivity for Claude and Cursor
- [MCP Video](https://github.com/studiomeyer-io/mcp-video): Cinema-grade video production via MCP
- [Agent Fleet](https://github.com/studiomeyer-io/agent-fleet): Multi-agent orchestration for the Claude Code CLI
- [AI Shield](https://github.com/studiomeyer-io/ai-shield): LLM security toolkit, direct and indirect injection, memory canary, circuit breakers
- [Darwin Agents](https://github.com/studiomeyer-io/darwin-agents): AI agents that improve themselves, now with GEPA-style reflective optimisation
- [MCP Armor](https://github.com/studiomeyer-io/mcp-armor): Drop-in Rust sidecar for MCP servers
- [n8n Templates](https://github.com/studiomeyer-io/n8n-templates): Production n8n workflows with cross-session memory

## Other public repos

Another 34 MIT-licensed repos sit behind those: MCP conformance harnesses and spec migrators, security sidecars, multi-tenancy libraries, n8n nodes, and the connectors for the hosted StudioMeyer services.

- [Full catalogue of all 42 repos](https://matthiasmeyer.tech/llms-full.txt): one block per repo, with description, language and package links.

## Concepts

Repo-agnostic deep dives on the protocols and patterns the repos are built on.

- [All 6 concepts](https://matthiasmeyer.tech/concepts): What is MCP, actually? · Stdio vs HTTP for MCP · Memory architectures compared · Agent-to-Agent protocol v1.0 RC · WebMCP for browser agents · Agent orchestration patterns.

## Books

My books are Kindle titles on AI, Claude, AI visibility and memory-first systems. Written by me with the help of an AI system, and honest about how that worked.

- [All 7 titles](https://matthiasmeyer.tech/books): status, price and buy link per title, in all three languages.
- [Amazon author page](https://www.amazon.com/author/studiomeyer): the same titles in Amazon's catalogue.

## API for AI agents

Open, CORS-enabled, no key needed. The four /api/v1 endpoints take ?lang=en|de|es and return the localized text next to the raw three-language record.

- /api/v1/repos: every repo as JSON, filter by group or tier
- /api/v1/repos/[slug]: one repo plus its related repos from the graph edges
- /api/v1/concepts: the concept articles
- /api/v1/books: the books with status, price and buy link
- /api/health: health check

## AI Agent Discovery

- /.well-known/agents.json: tool definitions for AI agents
- /.well-known/agent-card.json: A2A Protocol v1.0 agent card (JSON-RPC endpoint: /api/a2a)
- /.well-known/webmcp: WebMCP manifest (W3C CG Draft, Chrome 146+)
- /agent-card.json: the same A2A card at the root, as a fallback address
- /llms.txt: this file
- /llms-full.txt: full descriptions of every repo, concept and book
- /humans.txt: credits, tech stack and an index of every AI surface
- /.well-known/security.txt: RFC 9116 security contact
- /sitemap.xml: full URL list with hreflang
- /robots.txt: crawl rules, one group per named AI crawler

## Languages available

- Deutsch: https://matthiasmeyer.tech/de
- Español: https://matthiasmeyer.tech/es

English is the default and sits at the root. Every repo, concept and book page carries all three, and so do the JSON endpoints via ?lang=. A first visit is routed by the Accept-Language header, the choice is kept in the NEXT_LOCALE cookie, and the picker sits in the top-right of the header.

## About

matthiasmeyer.tech is the open-source hub of StudioMeyer, an AI and design studio in Palma de Mallorca. StudioMeyer Academy teaches the same stack for free. matthiasmeyer.tech is one of six connected domains in the StudioMeyer eco-system, all bound together through Schema.org parentOrganization and sameAs; the other five and what they do are listed in /llms-full.txt.
