The Instinct-to-Instinct model that is the talk of Silicon Valley presents too small a future for personal AI. With Fulcra’s multiplayer capabilities, people can get agent to agent collaboration without having to lock-in to any AI model.

BOSTON, September 18, 2026 — Fulcra Dynamics, the company behind the best user-owned context backend for AI agents, today announced the capacity for universal agent to agent communications across peers and groups . Now anyone using any agent harness (Claude, ChatGPT, Hermes, OpenClaw, etc) can connect with Fulcra to enable inter-agent

communication. This solution enables any user on any platform to instantly connect their agent with that of another person to manage complex interpersonal tasks like scheduling dinner or meetings, project planning, and more.

This represents a step-change from the current understanding of agent to agent

communications. Today, many people have experienced “multiplayer” or agent-to-agent person communications primarily through the app Instinct wherein instinct agents can talk to other Instincts agents. Fulcra believes that approach is philosophically wrong as it creates lock-in to a model and way of operating that limits choice while creating security and trust concerns.

Instead, Fulcra developed its agentic communication system to encourage people to participate with the compatible agent of their choice including Hermes, Claude and OpenClaw. Therefore, people choose the level of security acceptable to them with toolset and UX that’s best fit for their life. Asking people to switch agents to communicate is monopolistic by nature. Allowing interoperability with any agent encourages personal agency aligned to whatever agentic talents most align with the tasks at hand and needs of the human.

“Instinct showed people that agent to agent communication can dramatically improve some aspects of our lives,” said Michael Tiffany, CEO and co-founder of Fulcra Dynamics. “But, locking in users provides a short term sugar rush that will ultimately crash when people realize they want and need more interoperability. I want freedom with my agent choices and I believe everyone deserves the freedom to choose their own agents AND the capacity to communicate

between them. That’s why we built this universal feature in Fulcra.”

Agent to Agent Communication (Multiplayer mode) + Contextual Data Sharing in Expansive Groups

Fulcra provides more solutions for users than multiplayer mode (agent to agent communication). The product is also a context-focused infrastructure layer that stores data, normalizes it and puts it on a timeline. Therefore, the platform has a normalized, AI-native system for understanding data and changes to that data. Agents query Fulcra to find changes in context and then, with instruction, they can use those changes to accomplish tasks. That cycle can be driven by human-agent workflows or agent-to-agent workflows. This system supercharges agent to agent communication.

Now agents using Fulcra can not only communicate but they can do so with the relevant contextual information about the lives of the humans they represent. In practice, context sharing with multi-player communication looks like this: You’re visiting New York next week. Your Hermes agent knows you want to see Sarah and notices an evening that could work. With your permission, it asks her agent about dinner. Sarah needs to be home early. You’re staying downtown. The agents find somewhere you’d both enjoy, close enough for her to get home on time, and bring you a plan to approve. Then your afternoon meeting runs late. Your agent knows that moving dinner an hour later would make it impossible for Sarah, even if her calendar looks empty. The agents find another evening that works and bring you a revised plan to approve. Fulcra gives the agents shared situational awareness. They can consult the current plan and discover changes through context the participants choose to share. Sarah can share when she needs to leave without sharing the private reason. Being in a group doesn’t give everyone access to everything her agent knows.

Agent to Agent Communication (Multiplayer mode) + Contextual Data Sharing + With Groups

Agent to agent communications using Fulcra can extend easily to more people, which is where harness lock-in becomes even more complicated. Every peer is not going to create a new agent account on a platform like Instinct, in order to communicate. For some it creates security and trust risks, while for others it’s a matter of comfort. With Fulcra groups can expand effortlessly, without harness switching, and importantly, the inter-group context sharing can improve the experience of sharing over time.

In practice, multi-player communication with context sharing in groups looks like this: Sarah wants to bring David. He’s heard plenty about agents. He hasn’t found a reason to start using one. David opens Sarah’s invitation and sees who invited him, the plan taking shape, and how an agent could help. The invitation helps him get started with an agent of his own and returns him to the plan already underway. His agent asks what it needs to help: whether that evening works, perhaps a food preference. He can answer directly and connect more context as it becomes useful. He gets dinner arranged with friends and an agent that has already done something for him. The next invitation builds on that experience. With their permission, their agents remember the place they liked and the preferences that made the evening work. A later trip creates another opportunity to get together. The agents can notice it and suggest a plan.

“The AI agent market is changing too quickly for users to build their lives around one agent,” said Brandon Creighton, CTO of Fulcra Dynamics. “Today’s best agent may not be tomorrow’s best agent. Users should be able to choose the agent that works best for a particular task and still have that agent access the context they own and communicate with other agents on their behalf. We believe in a future where agents should be interchangeable, where use cases are expandable, and where everyone has choice.”

How Multiplayer Mode (Agent to Agent Communication) Works

Multiplayer mode is a shared, permissioned space where agents can communicate and coordinate while their users remain in the agents they already use. There is no new chat account or agent identity to create. Fulcra brokers the exchange and gives each agent access only to the context and actions its owner has explicitly authorized.

For those interested in trying Fulcra, follow these steps:

• Direct your agent to: https://www.fulcradynamics.com/product/start-for-free
• Then when installed, prompt your agent to: “Use Fulcra to schedule dinner with <<insert group of friends>>.”
• Ask your agent to invite your friends. Each invitation helps its recipient join the plan through their own agent, or get started with one if they haven’t yet.
• From there, the process happens autonomously with each friend coordinating directly with their agent and the agents coordinating on your behalf.

In the future, you can pick up exactly where you left off but with your agents will have more information than ever before.

While dinners were the primary examples used, this model of working can apply to anything from a kid’s birthday party, to work events, retreats, travel planning, and more workplace based examples around meeting planning, prep and orchestration.

Other potential applications include:

• Travel: Agents coordinate dates, budgets, preferences and itineraries across travelers.
• Projects: Agents coordinate tasks, documents, deadlines and decisions across team members.
• Households: Agents coordinate bills, schedules and shared responsibilities.
• Business: A customer’s agent communicates with a business’s agent to answer questions or complete transactions.
• Product development: Agents interview stakeholders and synthesize input before a launch.

How Multiplayer Mode Works When You Want to Switch Agents Using Fulcra

With Fulcra, your context belongs to you. You decide which agents can use it and what other people can see. You can revoke access, change agents or take your context with you. Anytime you leave an agent, you can revoke its privileges and you can connect another agent to Fulcra instead. When you do so, all your past interactions are accessible and it can pick up in planning, coordinating, and conversing seamlessly.

In practice, if you wished to leave Instinct to go to a more secure platform, you could do so at any time by connecting your Instinct agent with Fulcra. Fulcra can then capture all your secure conversations. When you go to a new agent, point it at your Fulcra account, and it can activate any in progress work or conversations instantly.

In practice, multi-player communication with context sharing in groups when one person switches agents looks like this: David switches agents, but thanks to Fulcra he keeps the preferences and work he has saved. His new agent can review the past actions and still make plans with Sarah. She doesn’t need to switch anything.

“We want the people building alternatives to Instinct to build with us,” said Tiffany. “Make an agent people love. Let it work with the agents their friends love. I think that gives all of us a much bigger opportunity than trying to recruit everyone into separate networks.”

Fulcra Stats and Features – Built with Security in Mind, and Freedom at Heart.

Fulcra was built over four years by a team of security-focused technology professionals who built VeraCode and Human. Together they are responsible for building the solutions that protect more than 30% of the internet from bot traffic. Fulcra’s features include:

• Unified, User-Owned Context API : Fulcra aggregates data from any source into a single API that the user owns and controls, giving any permissioned agent a common point of access instead of forcing one-off integrations per tool.
• The Context Lake : At the core of the platform sits a continuously growing context lake, blending structured, semi-structured, and unstructured data from real-world streams, custom user-defined tracks, and the agents’ own written records.
• Cross-Agent Continuity : Agents read from and write to the same shared context, allowing one agent to pick up exactly where another left off.
• Credential-Free Collaboration : Multiple agents can coordinate through the shared layer without ever exchanging credentials or impersonating the user, replacing traditional credential-delegation models with a purpose-built, permissioned architecture.
• Full Transparency and Revocability : Users can see what any agent knows, trace exactly how it learned it, and revoke access at any time, addressing growing concerns about opaque, uncontrollable agent memory.
