Implement A2A agents, MCP servers, and ACP editor integrations in Python.

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 Protocols

Connect agents and tools through the protocol required by the peers. A2A exchanges agent tasks, MCP exposes tools and context, and ACP connects agent clients such as editors to agents; these protocols are not interchangeable.

## Workflow

1. **Read only the needed guide**: read only the A2A, MCP, or ACP guide needed below. Use [mcp-setup](../mcp-setup/SKILL.md) for registering an existing MCP server in a host; registration is separate from implementing a client or server.
1. **Vet vendor skills through policy**: take vendor skills only from each guide's official-skill guidance, reviewed through the [vendor policy](../agent-project/references/vendor-skills.md) and installed project-scoped. A protocol capability named skill is not an installable Agent Skill.

## Task guides

<!-- guides:start -->

- [a2a](references/a2a.md): A2A clients, servers, Agent Cards, task lifecycle, and official guidance.
- [acp](references/acp.md): ACP editor-agent sessions, capability negotiation, streamed updates, and permission handling.
- [mcp](references/mcp/GUIDE.md): MCP tool and context clients/servers, transports, schemas, and protocol tests.

How to install

The exact contents, by fingerprint
mdr add fmind/dot/agent-protocols@sha256:9817b5ef1bda94dc

The line at the top of this page pins the label git:20261108.4bfae24, 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.
