Createve.AI Nexus MCP Client Server

A TypeScript implementation of an MCP server that connects to a remote Createve.AI Nexus server and exposes its functionality through the Model Context Protocol, for local deployment in tools that cannot connect to a remote MCP server.

Overview

This MCP client server acts as a bridge between AI assistants that support the Model Context Protocol and a remote Createve.AI Nexus server. It dynamically generates MCP tools and resources based on the API endpoints available on the Nexus server.

Features

Local Execution: Runs on the client machine, avoiding direct WebSocket connections to remote servers
API Abstraction: Interacts with the remote Nexus server via REST APIs
Enhanced Security: Keeps API keys local to the client machine
Dynamic API Discovery: Automatically discovers available APIs through OpenAPI schema
LLM-Optimized Interface: Formats responses in a way that's optimal for LLM consumption

Installation

npm install @createveai/nexus-mcp-server

Configuration

The MCP client server can be configured using environment variables or command-line arguments:

Environment Variables

CREATEVEAI_NEXUS_BASE_URL: The base URL of the Nexus server (required)
CREATEVEAI_NEXUS_API_KEY: API key for authentication (required)
CREATEVEAI_NEXUS_API: Optional API filter to limit exposed endpoints
DEBUG: Set to "createveai-nexus-mcp" to enable debug logging

Command-Line Arguments

--base-url <URL>: The base URL of the Nexus server
--api-key <KEY>: API key for authentication
--api <FILTER>: Optional API filter
--debug: Enable debug logging

Integration with AI Assistants

Claude Integration

Add the MCP server to your Claude environment by modifying the MCP settings configuration file:

{
  "mcpServers": {
    "createveai-nexus": {
      "command": "node",
      "args": ["/path/to/node_modules/@createveai/nexus-mcp-server/build/index.js"],
      "env": {
        "CREATEVEAI_NEXUS_BASE_URL": "https://nexus.createve.ai",
        "CREATEVEAI_NEXUS_API_KEY": "your-api-key-here"
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

Available Resources

The MCP client server exposes the following resources:

queue://{queueId}: Status and result for a queued request
schema://openapi: OpenAPI schema for all available APIs
schema://{api}: OpenAPI schema for a specific API (when using API filter)
docs://readme: Server documentation
docs://{path}: Specific documentation resource

Available Tools

The MCP client server dynamically creates tools based on the API endpoints available on the Nexus server. These tools follow the naming convention of the API paths with slashes replaced by underscores.

For example, an API endpoint at /api/text_processing/analyze would be available as the MCP tool text_processing_analyze.

Development Information

Build Process

This package includes pre-built JavaScript files in the repository to ensure reliable packaging and distribution. The TypeScript source is compiled to JavaScript during development, and the built files are committed to the repository.

If you make changes to the TypeScript source:

Run npm run build to compile the TypeScript code
Commit both the source changes and the updated build files

GitHub Workflow

The GitHub Actions workflow for this package relies on the pre-built files being present in the repository. It verifies their existence during the publishing process but doesn't attempt to rebuild them.
