onetool-mcp vs eclipse-chatgpt-plugin
onetool-mcp: OneTool MCP is a single MCP server that bundles 100+ tools — Brave search, Google, Context7, AWS, Playwright, Chrome DevTools, Excel, database operations, and more. Instead of registering each tool individually and burning context on their definitions, agents write short Python code to call any tool on demand. Anthropic engineering research backs this approach: code execution reduces token usage by over 98%, cutting costs dramatically when agents need many external tools.; eclipse-chatgpt-plugin: AssistAI is an Eclipse IDE plugin that exposes the entire development environment as an MCP (Model Context Protocol) server. External AI agents can read, navigate, edit, build, test, run, and debug Java projects through Eclipse APIs, preserving workspace sync, local history, and incremental compilation. It also includes a built-in LLM chat view for quick inline interactions.

TL;DR
Choose onetool-mcp if…Cutting MCP token overhead when an agent needs 10+ external tools
Choose eclipse-chatgpt-plugin if…AI-assisted coding where external agents (Claude Code, etc.) control Eclipse to edit, build, and debug projects
