概要

What is Unstorage MCP Server?

A Key-Value storage MCP server based on unjs/unstorage. It mounts multiple storage backends (memory, filesystem, Redis, MongoDB, HTTP server) and exposes CRUD operations as MCP tools. Designed for developers who need to interact with diverse key-value stores through an AI agent or MCP client.

How to use Unstorage MCP Server?

Install via npm with npx @slow-groovin/unstorage-mcp, configuring drivers through environment variables (e.g., REDIS_URL, MONGODB_URL, FS_BASE, HTTP_BASE). Use arguments like --disable-modify to restrict write operations. Run with an MCP inspector or as a local dev server using tsx.

Key features of Unstorage MCP Server

Supports memory, filesystem, Redis, MongoDB, and HTTP storage drivers.
Provides 12 tools: showMounts, getItem, getItems, getItemRaw, getMeta, getKeys, setItem, setItems, setItemRaw, setMeta, removeItem, removeMeta.
--disable-modify flag to forbid destructive tools.
Automatic fallback to memory driver when no root mount is defined.
Easy to extend: clone repo, copy a driver file, and implement.
Environment variables configure driver-specific base paths and mount points.

Use cases of Unstorage MCP Server

Let an AI assistant read and write key-value data in Redis, MongoDB, or the filesystem.
Provide a unified MCP interface to multiple storage backends for debugging or operations.
Enable AI agents to store session state, configuration, or temporary data across runs.
Quickly test or prototype storage interactions without writing a custom MCP server.

よくある質問

What drivers does Unstorage MCP Server support out of the box?

Memory, filesystem, Redis, MongoDB, and unstorage HTTP server.

Can I disable write operations to prevent accidental modifications?

Yes, pass the `--disable-modify` argument to the server. This disables `setItem`, `setItems`, `setItemRaw`, `setMeta`, `removeItem`, and `removeMeta`.

How do I configure the Redis driver?

Set the `REDIS_URL` environment variable (e.g., `redis://user:pass@host:6379`). Optionally set `REDIS_BASE` and `REDIS_MOUNT_POINT`. Similarly for MongoDB, filesystem, and HTTP drivers.

What happens if I don’t define any root mount?

A memory driver is automatically mounted on `"/"`, mirroring the default behavior of unstorage.

How can I add a new storage driver?

Clone the repository, copy an existing driver file (e.g., `src/storage/redis.ts`), modify it to use the desired unjs/unstorage driver, test, and optionally open a pull request.
