### Description (declared)

# HotKV MCP Server

A [Model Context Protocol](https://modelcontextprotocol.io) server for [HotKV](https://hotkv.com),
a RESP2/RESP3-compatible in-memory data store with built-in AI and LLM-serving features (semantic
and prompt caching, agent memory, RAG, feature store, rate limiting, time series and more).
It lets an AI assistant or agent (Claude, Cursor, VS Code, your own) read and write keys, keep
conversation memory and notes, log events, store prompt templates and search documents in a
HotKV server.

- A fixed set of 28 tools. There is no tool that runs an arbitrary command, so an agent cannot
  flush a database, change the server's configuration or read the keys of other tenants.
- `--read-only` removes every write tool, so the agent cannot even see them.
- `--namespace` confines the agent to one prefix: it can only use and list names under it.
- Results are capped (`--max-value-bytes`, `--max-items`), and a cut value is flagged
  `truncated`, so a huge value cannot flood the model's context.
- stdio for local clients, streamable HTTP for shared use.

Written against HotKV server 0.3.0 and the official `hotkv-client` Python package.

## Install

```bash
pip install hotkv-mcp
```

or run it without installing, with [uv](https://docs.astral.sh/uv/):

```bash
uvx hotkv-mcp --url hotkv://localhost:6379
```

Python 3.10 or newer.

## Connect a client

The server speaks stdio by default, so a client launches it as a subprocess.

**Claude Code**

```bash
claude mcp add hotkv -- uvx hotkv-mcp --url hotkv://localhost:6379
```
