- Multi-component (OASF schema discovery; SLIM messaging; identity; observability)
- core_mechanism
- AGNTCY bundles the building blocks of an 'Internet of Agents': Agent Discovery via OASF, cryptographically verifiable Agent Identity and access control, Agent Messaging via SLIM (Secure Low-latency Interactive Messaging), and end-to-end Agent Observability. Cisco open-sourced it in March 2025 with LangChain and Galileo; it joined the Linux Foundation on 29 July 2025.

{"predicate":"competes_with","target":"a2a","note":"AGNTCY's interop stack overlaps with A2A as a multi-agent collaboration layer (though AGNTCY also supports A2A)."}{"predicate":"complements","target":"acp","note":"ACP (Agent Communication Protocol) is associated with the AGNTCY community as a REST messaging option."}- ideal_use_case
- Standing up a vendor-neutral multi-agent system with discovery, identity, secure messaging and observability out of the box.
- when_to_use
- When you need the full 'Internet of Agents' infrastructure stack rather than a single protocol like MCP or A2A.
- when_not_to_use
- When a single interop protocol (A2A) or tool protocol (MCP) covers your need without adopting a whole framework.
- code_example
- // AGNTCY is an infrastructure project, not one wire format. // Discover an agent via OASF, message it via SLIM: // directory.lookup('researcher') -> slim.connect(agent.endpoint)
