CB Insights MCP Server

_Deprecation notice: This repository, serving as an example implementation of a simple self-hosted MCP server that acts as a pass-through to the CB Insights API, is deprecated as of January 2026. CB Insights is pleased to offer a fully supported MCP server at mcp.cbinsights.com, which can be invoked programmatically or through clients like ChatGPT, Claude, and Microsoft Copilot._

The CBI MCP Server provides an interface for developers to interact with CB Insights ChatCBI LLM through AI Agents.
