Nest Llm Aigent

What is Nest Llm Aigent?

Nest Llm Aigent is a forwarding/proxy solution that wraps multiple MCP (Model Context Protocol) servers into a unified HTTP service for large language models. Designed for developers integrating MCP capabilities into existing web services (e.g., NestJS), it acts as an AI agent that centralizes configuration and exposes standardized RESTful endpoints.

How to use Nest Llm Aigent?

Install MCP servers as private NPM packages and configure them in an mcp.config.json file. The running service exposes POST endpoints at paths like /api/mcp/tools, /api/mcp/tools/call, and /api/mcp/agent for HTTP-based access to tools, resources, and LLM invocation.

FAQ from Nest Llm Aigent

What transport protocol does Nest Llm Aigent use for MCP servers?

Currently only stdio transport is implemented; SSE server support is planned for future versions.

How are MCP servers deployed and configured?

MCP servers are packaged as private NPM packages, installed via npm install, and configured in a mcp.config.json file defining server path, arguments, and name.

What endpoints does Nest Llm Aigent expose?

POST endpoints at /api/mcp/tools, /api/mcp/functools, /api/mcp/tools/call, /api/mcp/resources, /api/mcp/prompts, /api/mcp/all, and /api/mcp/agent.

Does Nest Llm Aigent support all large language models?

Yes, the project aims to support nearly all large model invocations through its HTTP API.

Where does tool execution happen?

Nest Llm Aigent is a forwarding layer; actual tool execution occurs in the connected MCP servers, which it bridges to HTTP requests.
