What the code does

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

      return path.join(raw, fileNameForDir);

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

This one needs environment variables set before it will start: VRCHAT_MCP_CONFIG_FILE (Path to a JSON config file for settings not supplied through environment variables.), VRCHAT_MCP_USER_AGENT (Descriptive User-Agent for VRChat API requests.), VRCHAT_MCP_LOG_LEVEL (Log level for stderr diagnostics.), VRCHAT_MCP_COOKIE_STORE (Cookie storage backend for VRChat authentication. The keychain mode falls back to file storage if the OS keychain is unavailable.), VRCHAT_MCP_COOKIE_FILE (Cookie file path used when VRCHAT_MCP_COOKIE_STORE is file.), VRCHAT_MCP_ALLOW_WRITES (Allow non-GET VRChat API write operations. Defaults to true for local full-capability use; set to false for read-only mode.), VRCHAT_MCP_UPLOAD_ROOTS (Absolute directories from which local PNG uploads may be read. Separate multiple roots with the platform path delimiter.). The author declared them in the registry entry; get the values from the project itself.
