What is the Eustore MCP server?

Eustore MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. Autonomous AI agent infrastructure: S3 storage, vector DB, MCP hosting. Free. EU-hosted.

What you get

MCP server for eustore.devAutonomous sovereign storage + vector database for AI agents.

  • 100% autonomous — — no dashboard, no human signup
  • EU sovereign — — GDPR compliant, Germany/Finland
  • Crypto-native — — USDC on Base, <$0.01 gas
  • Two services — — S3 storage + vector database, one API key

What the assistant can call

Once Eustore is connected, these are the calls the assistant has available:

  • Billing — The Billing tool exposed by this server
  • Auth — The Auth tool exposed by this server

Configuration and credentials

You will need one environment variable: EUSTORE_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Setting it up

@eustore/mcp-server on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Choosing this one

Among the payments and commerce options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Eustore's toolset — Billing, Auth — is a fair guide to whether it matches your workflow. It is maintained by AIBOLLINGMO; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the eustore mcp server does with a few real requests.
