How to connect Kontor MCP

Kontor MCP runs locally from a Node.js package published to the npm registry: @kontor-mcp/server version 1.0.4. 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 @kontor-mcp/server@1.0.4. It reads these environment variables: KONTOR_MAX_FILE_MB and KONTOR_LANG_DEFAULT; set them in the client's configuration for this server.

Kontor MCP runs locally from a container image in an OCI registry such as Docker Hub or GitHub Container Registry: ghcr.io/dashankanadeeshandesilva/kontor-mcp:1.0.4. The package starts a local server that speaks MCP over Streamable HTTP; the client then connects to it by URL. It reads the environment variable KONTOR_AUTH_TOKEN (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": {
    "kontor-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@kontor-mcp/server@1.0.4"
      ],
      "env": {
        "KONTOR_MAX_FILE_MB": "<value>",
        "KONTOR_LANG_DEFAULT": "<value>"
      }
    }
  }
}
