A synchronized, multi-client state protocol for AI agent sessions.

Read the documentation →

The Agent Host Protocol (AHP) defines how a portable, standalone sessions server communicates with its clients. Multiple clients can connect to the server and see a synchronized view of AI agent sessions through immutable state, pure reducers, and write-ahead reconciliation.

• Swift — Add https://github.com/microsoft/agent-host-protocol as a Swift Package Manager dependency to use the AgentHostProtocol library. See clients/swift/ for an example iOS client. The Package.swift manifest lives at the repository root because SwiftPM only resolves manifests at the root of a remote git repo; the actual Swift sources live under clients/swift/AgentHostProtocol/.
• Rust — See clients/rust/ for the ahp, ahp-types, and ahp-ws crates.

For consumers that need to talk to two or more hosts at once, the Rust SDK ships a MultiHostClient abstraction in ahp::hosts; single-host consumers use the same API via MultiHostClient::single. See Connecting to Multiple Hosts for the design and surface. A matching Swift API is planned in a follow-up PR.
