Model Context Protocol (MCP) Server Directory

AI-powered research is taking a quantum leap forward as the new Dimensions MCP servers launch, granting agents direct access to 150M+ scientific publications and patents.

Microsoft is fundamentally changing how AI agents operate in production by introducing strict MCP (Model Context Protocol) allowlists for GitHub Enterprise.

Package AI agent capabilities into portable, vendor-neutral Agent Plugins that bundle Skills with MCP servers, then automate schema validation, multi-client smoke tests, and catalog publishing.

Architect a stateless MCP server on Cloudflare Workers that survives restarts between rounds of a human approval gate using MRTR requestState, the tasks extension, and RFC 9207 OAuth verification.

Operate OpenAI's GPT-5.6 programmatic tool calling in production: let Luna, Terra, or Sol author typed JavaScript that orchestrates allowlisted tools inside the OpenAI sandbox, with approval gates, step budgets, and OpenTelemetry tracing.

Google's Agentic Resource Discovery (ARD) protocol, built under the Linux Foundation AAIF, lets an agent ask what is available before anything runs. This guide builds a stateless ARD-style MCP discovery server that indexes plugins, MCP servers, and skills and answers query-by-task searches with ranked, cacheable results.
