01 · Install Klever Vm

before you install - you'll need

Set STORAGE_TYPE, MEMORY_MAX_SIZE, REDIS_URL before connecting.

Claude Code

claude mcp add klever-io-mcp-klever-vm --transport http https://mcp.klever.org/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "klever-io-mcp-klever-vm": {
      "url": "https://mcp.klever.org/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to mcp.klever.org

endpoint auth accepted our unauthenticated MCP initialize - no credentials needed to connect

license MIT - declared in the repository

npm package @klever/mcp-server - the @klever scope differs from the repo owner (klever-io); confirm it's the project's official package

registry namespace io.github.klever-io is GitHub-verified and matches the repo owner
