Schema crate and versioned JSON Schema artifacts for SDK generators; higher-level Rust runtime crate for implementers. Reuses MCP-style JSON where it fits, plus agent UX types such as diffs. Markdown is the default user-facing text format.

Full remote/cloud agent support is still in progress. Schema artifact versions can move without changing wire compatibility, which matters if you generate SDKs from the JSON Schema. Vs MCP (tool/server protocol for model context): ACP is the editor↔agent session protocol; they solve different layers and often ship together.","verdict":"The interoperability bet for coding agents — adopt it when you build an editor or an agent, not when you just want a chat UI.","addedAt":"2026-10-12","featured":false,"domain":"AI Agents","subSpecialty":"Agents","subcategory":"Agent Frameworks & SDKs","tags":["api","self-host","permissive","coding-agents","realtime","active"],"capabilities":[],"surfaces":["API","Self-host"],"ecosystem":["Multi-platform"],"licenseModel":"Apache-2.0","githubStars":4464,"starsPerWeek":65,"access":"free","archived":false,"repo":{"createdAt":"2025-06-23","pushedAt":"2026-10-18","license":"Apache-2.0","archived":false,"checkedAt":"2026-10-19"},"links":{"self":"/api/gems/agent-client-protocol","html":"/gems/agent-client-protocol","markdown":"/gems/agent-client-protocol.md"}},{"slug":"agentscope","name":"AgentScope","tagline":"Apache-2.0 agent framework for capable LLMs","category":"agents","url":"https://docs.agentscope.io","github":"https://github.com/agentscope-ai/agentscope","pricing":"open-source","hook":"AgentScope is a Python framework for building and running LLM agents.
