Overview

Enables cross-session, networked mentions between coding agents so teams can @mention another team's AI and integrate across sessions, machines, and orgs from the terminal. Operates as a messaging/relay layer that ties individual agent sessions together, forwarding context and mentions to remote agent endpoints. Distinctive for its CLI-first experience and focus on developer workflows for coding agents (supports Claude/Code models and LLM toolchains). Agent-to-Agent Protocol and Tool Use Pattern help align multi-agent tooling alongside this capability.

Key Benefits

As agents collaborate across teams and environments, a simple way to reference and invoke remote agents becomes essential for tracing interactions and assigning responsibility. AgentParty provides the connective tissue to record who called whom and surface cross-session calls—information that matters when building agent track records, reputations, and post-hoc evaluations. Until projects include these signals, evaluating agent-to-agent trust and failure modes will miss real-world cross-team interactions. Model Context Protocol (MCP) offers a standardized context model to support these signals.

Ideal For

Developer teams who need a lightweight, CLI-driven way to invoke and link coding agents across sessions, machines, and organizations. Role-Based Agent Pattern provides design guidance for structuring such interactions and permissions across agents.

Real-World Examples

Connect remote coding agents so one team's agent can @mention and trigger another team's AI from the terminal
Capture cross-session interaction context to aid post-run evaluation and build agent track records
Prototype agent delegation workflows across machines and org boundaries without heavy orchestration
