Introducing AIPM: The First Open Protocol for AI Agent Interoperability

Building bridges between AI agents from different vendors

TL;DR

AIPM (Agent Interoperability Protocol Models) is a new open-source protocol that enables AI agents from different vendors—OpenAI, Claude, LangGraph, AutoGen, CrewAI, and more—to communicate securely and collaborate seamlessly. Think of it as HTTP for AI agents, but with built-in trust, capability discovery, and cryptographic security.

🔗 Repository: bhaskarvilles/aipm
🎮 Interactive Demo: aipm-demo
📦 Python SDK: Available now (Phase 1 complete)
🚀 Status: Core protocol released, Phase 2 in planning

The Problem: Isolated AI Agents

Today's AI landscape is fragmented. We have powerful agents from:

OpenAI (GPT-based assistants)
Anthropic (Claude agents)
LangChain/LangGraph (Orchestration frameworks)
AutoGen (Microsoft's multi-agent framework)
CrewAI (Role-based agent teams)
And dozens more...

Each uses its own protocols, APIs, and conventions. They can't talk to each other.

Imagine if different email services couldn't communicate. That's where we are with AI agents today.

The Vision: An Interoperable AI Ecosystem

AIPM solves this by providing:

Standard Identity Layer - How agents identify themselves
Capability Discovery - What skills and tools each agent has
Secure Handshake - TLS-inspired connection establishment
Trust Layer - Reputation and reliability tracking
Task Negotiation - Accept/decline work based on capability
Memory Exchange - Efficient context sharing
Economic Layer - Fair billing between agents

Real-World Use Cases

1. Multi-Vendor Workflows

User Request: "Analyze this dataset and create a presentation"
  ↓
OpenAI Agent (data analysis)
  → discovers LangGraph Agent (workflow orchestration)
    → delegates to Claude Agent (content writing)
      → coordinates with Stable Diffusion Agent (visuals)
        ✓ Complete presentation delivered

2. Skill Marketplace

Need OCR? Your agent discovers and delegates to a specialized OCR agent—regardless of vendor. Pay only for what you use.

3. Trust Networks

Agents build reputation over time. High-trust agents get priority access to premium services and better rates.

4. Enterprise Integration

Connect your internal agents with external services while maintaining security boundaries and compliance requirements.

How It Works: The Handshake Protocol

AIPM uses a 7-step handshake protocol inspired by TLS:

Agent A                          Agent B
   |                                |
   |------- HELLO ----------------->|
   |         (identity + session)   |
   |                                |
   |<--- CAPABILITY_EXCHANGE -------|
   |         (skills + models)      |
   |                                |
   |------- AUTHENTICATION -------->|
   |         (challenge)            |
   |                                |
   |<--- PUBLIC_KEY_EXCHANGE -------|
   |         (Ed25519 keys)         |
   |                                |
   |------- TRUST_VERIFICATION ---->|
   |         (reputation scores)    |
   |                                |
   |<--- READY ---------------------|
   |         (session established)  |
   |                                |
   [Ready for task delegation]

Technical Deep Dive

Protocol Design

AIPM uses JSON-based messages with this structure:

{
  "id": "uuid-v4",
  "type": "handshake.hello",
  "version": "1.0.0",
  "sender": {
    "agent_id": "agent-openai-001",
    "organization_id": "openai"
  },
  "receiver": {
    "agent_id": "agent-langgraph-001",
    "organization_id": "langchain"
  },
  "timestamp": "2026-07-06T08:00:00Z",
  "priority": "normal",
  "payload": {
    "identity": {
      "name": "OpenAI Assistant",
      "capabilities": {
        "skills": ["text-generation", "code-review"],
        "models": ["gpt-4", "gpt-3.5-turbo"],
        "tools": ["code-interpreter", "web-browser"]
      }
    }
  },
  "signature": {
    "algorithm": "Ed25519",
    "value": "base64-signature",
    "public_key_fingerprint": "sha256-hash"
  }
}

Agent Identity

Every agent declares:

identity = AgentIdentity(
    agent_id="unique-id",
    organization_id="vendor-id",
    name="Human Readable Name",
    version="1.0.0",
    capabilities=Capabilities(
        skills=["skill1", "skill2"],
        models=["model1", "model2"],
        tools=["tool1", "tool2"],
        max_context=128000,
        memory_support=True
    ),
    trust_score=TrustScore(
        reliability=0.99,
        accuracy=0.95,
        avg_latency_ms=250.0,
        success_rate=0.98
    )
)

Python SDK Example

from aipm import AIPMAgent, AgentIdentity, Capabilities

# Create your agent
agent = AIPMAgent(
    AgentIdentity(
        agent_id="my-agent-001",
        organization_id="my-org",
        name="My AI Agent",
        version="1.0.0",
        capabilities=Capabilities(
            skills=["text-generation"],
            models=["gpt-4"]
        )
    )
)

# Discover and connect to another agent
peer = AgentReference(
    agent_id="peer-agent-001",
    organization_id="peer-org"
)

# Initiate handshake
hello_msg = agent.initiate_handshake(peer)

# Process messages (handled by protocol)
response = agent.process_message(hello_msg)

# Check if ready
if agent.is_ready(peer):
    # Send task request
    task = agent.create_task_request(
        peer,
        task_description="Analyze this dataset",
        priority="high"
    )

Technical Comparison

AIPM vs MCP (Model Context Protocol)

Feature	AIPM	MCP
Purpose	Agent-to-agent communication	Model-to-tool connection
Scope	Multi-vendor interoperability	Single-vendor integration
Trust Layer	Yes (reputation scoring)	No
Economic Layer	Yes (billing/payments)	No
Handshake	7-step secure protocol	Simple connection
Signatures	Ed25519 cryptographic	N/A
Target	Autonomous agents	LLM applications

Both protocols can coexist! MCP connects models to tools; AIPM connects agents to each other.

Why This Matters

For Developers

Stop rebuilding: Use existing agents instead of creating new ones
Mix and match: Combine best-of-breed agents from any vendor
Scale easily: Add capabilities without architectural changes
Save money: Pay only for what you use

For Organizations

Vendor independence: No lock-in to single provider
Cost optimization: Route tasks to most cost-effective agents
Compliance: Maintain security boundaries across vendors
Innovation: Experiment with new agents without migration

For the AI Ecosystem

Specialization: Agents can focus on specific domains
Competition: Better agents win based on capability, not vendor
Standards: Common language enables rapid innovation
Trust: Reputation system creates accountability

FAQ

Q: Is AIPM production-ready?
A: Phase 1 (core protocol) is complete. We recommend waiting for Phase 2 (transport layer) for production use.

Q: What about security?
A: AIPM uses Ed25519 signatures, challenge-response auth, and session management. Phase 2 will add end-to-end encryption.

Q: Can I use this with my existing agents?
A: Yes! Implement the AIPM protocol in your agent using our SDK, or create an adapter/wrapper.

Q: How does billing work?
A: Phase 3 will implement the economic layer. For now, agents declare their costs in the identity layer.

Q: What about privacy?
A: Agents control what capabilities they expose. Memory exchange is opt-in. Full encryption coming in Phase 2.

Q: Can I host my own agent registry?
A: Yes! The protocol is decentralized. Any organization can run a registry.

Q: What languages are supported?
A: Python SDK is available now. JavaScript, Rust, and Go SDKs are planned.

Q: How do I report security issues?
A: Open a discussion on the repository with "Security" tag or contact the maintainers directly.
