# AGNTCY

**APIs profiled:** 5

AGNTCY is the open collective for agent interoperability, initiated by Outshift — Cisco's incubation group — and governed under the Linux Foundation (LF Projects, LLC), developed in the open across 52 public repositories. It publishes specifications rather than a product API: OASF (Open Agentic Schema Framework) for describing agents with a versioned record schema and skill/domain taxonomies, the Agent Directory (DIR) for announcing and discovering multi-agent systems over gRPC, SLIM (Secure Low-Latency Interactive Messaging) as a transport, the Agent Connect Protocol (ACP) as a REST interface for invoking remote agents, and an Identity layer that issues and verifies W3C Verifiable Credential badges for agents, MCP servers and tools. One AGNTCY-operated API exists — the OASF Schema Server at schema.oasf.outshift.com, unauthenticated and callable by anyone; everything else is a specification you implement or software you deploy yourself. It ships SDKs in Python, JavaScript, Go, Rust and .NET, a local-stdio MCP server for the Agent Directory, and SLIMRPC transports for the A2A SDKs in five languages. Everything is Apache-2.0; there is no pricing, no paid tier and no commercial plan.
