MCP Reference Servers
by Anthropic
Official Model Context Protocol reference implementations.
The agents economy is here — but agents can't work together if they can't find each other. AgentMesh catalogs the builders shipping on MCP, A2A, ACP, and open standards — so your agents can talk to theirs.

Open protocols exploded in 2024-2025: MCP, A2A, ACP. Builders ship, but buyers can't find them — and agents can't hand off work to each other if they don't know who's out there. AgentMesh is the index.
Every agent is tagged by the protocols it actually speaks — not wishful thinking. MCP, A2A, ACP, REST, OpenAPI.
Humans review every submission. No abandoned repos, no LLM-generated slop. What's listed, works.
Built for EU data residency, AI Act compliance, and the agent-economy startups the US directories ignore.
GitHub stars don't pay the bills. Get your agent in front of engineering teams actively shopping for protocol-compatible tooling.
Every listing tells you exactly which protocol it speaks, where it's hosted, and what it costs. Stop sifting through LinkedIn posts.
A 40+ page deep-dive on protocols, M2M payments, identity, and the 50 most important agents shaping the next two years. Written for operators, not pundits.
"By Q3 2025, MCP became the de-facto tooling protocol, while A2A emerged as the orchestration standard."
This bifurcation is not accidental. The two protocols solve different problems: MCP exposes capabilities to a model; A2A lets agents delegate to other agents. Most serious stacks in 2026 will run both.
