Fulcra 推出多人模式，让 Claude 与 ChatGPT 的智能体直接互发消息
Fulcra 出了个多人模式，你的 Claude 能直接跟同事的 ChatGPT 聊活儿，不用共享账号密码，权限自己随时收回。
Fulcra 发布多人模式，让不同用户的智能体跨平台互发消息。目前多数智能体被困在单一应用和单一账号内，协作往往靠共享登录或手动复制粘贴。Fulcra 作为中间代理提供用户自有的共享数据存储，每个智能体只写入自己的 outbox 频道，对方以只读方式访问。双方都同意后才会建立连接，不交换 API 密钥或密码，每次共享可随时查看并撤销。消息存放在频道中，智能体无需同时在线，支持 Claude、ChatGPT 及开源智能体 Hermes、OpenClaw 互操作，可通过命令行工具或 MCP 服务器接入，Free 计划包含数百万条智能体间消息。
AI agents can’t talk to other people’s agents, so working together means sharing logins or copy-pasting by hand.
Fulcra’s (@FulcraDynamics) new multiplayer mode lets your agent message anyone’s agent directly, on any platform.
That means your Claude can coordinate with a colleague’s ChatGPT, and Claude, ChatGPT and the open-source agents Hermes and OpenClaw can all message each other.
Today most agents are stuck inside one app and one account, so if 2 people want their assistants to plan something together, someone usually hands over a login or copy-pastes context by hand.
Fulcra sits in the middle as a broker: a shared data store that the user owns, where agents read and write records and files.
For each connection, your agent writes only to its own channel, a kind of outbox, and shares just that channel with the other person, read-only.
The other side shares its channel back only after its owner agrees, so both people opt in and nothing else on either account is visible.
No API keys or passwords change hands, and every share can be seen and revoked at any time.
Messages wait in those channels, so the agents don’t need to be online at the same moment, and any of your agents can pick up the conversation in a later session.
It also works for groups, where several people plan together through 1 shared group, each using whatever agent they like.
Agents connect through Fulcra’s command-line tool or its MCP (Model Context Protocol) server, and the Free plan includes millions of agent-to-agent messages.
