How to connect Silvanexum

Silvanexum runs locally from a Node.js package published to the npm registry: @silvanexum/mcp version 0.4.0. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y @silvanexum/mcp@0.4.0. It reads these environment variables: SILVANEXUM_API_KEY (required, secret) and SILVANEXUM_BASE_URL; set them in the client's configuration for this server.

Silvanexum runs locally from a Python package published to PyPI: silvanexum-mcp version 0.2.0. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Python; clients usually start it with uvx (from uv) or after pip install — the usual command is uvx silvanexum-mcp. It reads the environment variable SILVANEXUM_API_KEY (required, secret); set it in the client's configuration for this server.

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

{
  "mcpServers": {
    "silvanexum": {
      "command": "npx",
      "args": [
        "-y",
        "@silvanexum/mcp@0.4.0"
      ],
      "env": {
        "SILVANEXUM_API_KEY": "<secret>",
        "SILVANEXUM_BASE_URL": "<value>"
      }
    }
  }
}
