# X Post — Agent History Protocol Launch (Single Long Post)

---

AI agents are no longer demos. They're approving refunds, managing infrastructure, calling APIs, making decisions that affect real users and real money.

Multiple platforms build them — LangChain, CrewAI, AutoGen, OpenClaw, custom stacks. Multiple protocols power them — HTTP, MCP, A2A. And this is just the beginning.

Soon it will be common for two different enterprises' agents to transact with each other. For your personal AI agent to negotiate with a company's agent on your behalf. The agentic future is multi-party, cross-boundary, and autonomous.

But reliability and observability are nowhere near ready for this.

Every framework logs differently. Most don't log at all. AI hallucination is still an unsolved problem — an agent can fabricate a tool call, misrepresent what the LLM returned, or act without proper authorization. And you'd never know.

Now think about where agents are headed — healthcare, finance, defense, critical infrastructure. In these strategic environments, a rogue AI or a cyber attack exploiting an agent isn't hypothetical. It's inevitable. Tamper-proof recording of every agent action isn't optional — it's a necessity.

The need for a common observability protocol is urgent. Not a framework-specific logger. A standard.

I built Agent History Protocol (AHP) — an open standard for tamper-evident, hash-chained recording of every AI agent action. Every HTTP call, MCP tool use, A2A message, LLM inference, and authorization decision → cryptographically linked, append-only, verifiable.

What it detects:
→ Modified records (tool calls, inferences, authorizations) — hash chain breaks
→ Deleted records from the middle — sequence gap + hash mismatch
→ Inserted fake records — hash chain breaks at insertion point
→ Reordered records — sequence + hash mismatch
→ An agent lying about what it called, what authorization it had, or what the LLM said

With cryptographic signing (Level 2): forged records from a different agent fail Ed25519 verification. Checkpoint tampering is caught by Merkle root signature.

With independent witnesses (Level 3): even if an agent deletes its entire chain, signed receipts prove it existed.

What it does NOT prevent:
→ Reading the chain (it's not encrypted)
→ A compromised agent writing false records going forward
→ Bad actions before they're recorded

Think of it like a flight recorder on an airplane — it doesn't prevent the crash, but it makes it impossible to lie about what happened afterward. An enterprise auditor can run `ahp verify` on any chain and know immediately if anything was changed.

Framework-agnostic. Python and TypeScript SDKs with auto-instrumentation — drop into any agent system, no code changes.

pip install ahp-sdk
npm install open-ahp

Open source. Ready to use.
