onetool-mcp vs fhir-mcp-server

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.; fhir-mcp-server: The FHIR MCP Server is a Model Context Protocol server that enables seamless integration with FHIR APIs. It acts as a bridge between AI/LLM tools and healthcare data, making it easy to search, retrieve, and analyze clinical information. It supports multiple transport protocols and SMART-on-FHIR authentication.
