Nexatron

Nexatron is a remote MCP server: there is nothing to install. Its endpoint is https://api.nexatron.io/api/v1/mcp, served over Streamable HTTP. In an assistant that accepts remote MCP servers (often under a setting named connectors, integrations or tools), add a new server and give it this URL; in a client configured by file, add it as a remote (HTTP) server with the same URL.

It also lists an endpoint on the older SSE transport https://api.nexatron.io/api/v1/mcp/stream. Clients that support remote servers generally still accept SSE endpoints, though the protocol now favours Streamable HTTP.

No headers are declared in the registry entry. If the server needs you to sign in, a client that supports MCP authorization opens the service's own sign-in page when it first connects.

It can also run locally from a Python package published to PyPI: nexatron-mcp version 1.0.0. 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 nexatron-mcp. It reads these environment variables: NEXATRON_API_KEY (required, secret) and NEXATRON_URL; set them 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": {
    "nexatron-mcp": {
      "command": "uvx",
      "args": [
        "nexatron-mcp"
      ],
      "env": {
        "NEXATRON_API_KEY": "<secret>",
        "NEXATRON_URL": "<value>"
      }
    }
  }
}
