Use when an agent speaks MCP, A2A or a gateway beyond its process: MCP server or client, agent cards, MCP Registry, delegated calls. Triggers: "MCP server" / "MCP-сервер", "A2A", "шлюз для агентов". Not for one server's tool design (agent-harness) or skill construction (make-skill).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Agent interop — the protocols an agent speaks outside its own process `agent-orchestrator` builds the loop. `agent-evals` proves it behaves. This skill covers everything the loop reaches that is **not in its process**: a tool server, a peer agent, a registry, and the gateway between them. --- ## Triggers "MCP client", "agent interoperability", "server.json", "agentgateway", "tool federation", "интероперабельность агентов", "реестр MCP", "delegation token", "токен делегирования". Moved here from the description in 0.31.3: "карточка агента". ## Rule zero — a protocol claim without a date is a guess Every one of these specifications moved in the twelve months before **2026-08-13** — the date every reference below was read — and each moved in a way that silently breaks code written against the previous revision. Concretely, and each one measured on that date against the live specification rather than recalled: - MCP replaced the `initialize` handshake with `server/discover` and made the protocol **stateless**; a client that opens with `initialize` is speaking a revision that is on its way out. …

How to install
mdr add ssheleg/agent-stack/agent-interop@sha256:bc6a69e54c89a368The line at the top of this page pins the label git:20261028.52b0584, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
