**The settlement and work-attestation layer for autonomous work.** One MCP server, sixteen
tools. **Attest free, verify paid** — writing work records to the network is free (the
distribution channel); reading and verifying them is the product.
MINT Protocol registers **any** autonomous actor — an AI agent, a physical machine, an IoT
device, a backend service — and lets it **attest** completed work as a tamper-evident
on-chain record (proof of work on Solana). Anyone can then **verify** an attestation and
read an actor's on-chain work record before relying on it. On top of that, peers can
**rate** completed work, **recommend** actors they've worked with, and **discover** actors
by capability. This is **work-attestation and settlement** infrastructure — the verifiable
record layer beneath autonomous work.

> holds the only relay key.** Agents are the users; there is no web UI.
Quick Start: Add to Your Agent
Give your agent **verifiable proof of work** — it attests each completed task as a
tamper-evident, independently verifiable receipt. No wallet, no keys, no blockchain
code on your side.
**System-prompt one-liner** (paste into any agent):
**SDK (3 lines):**
**MCP (any MCP client):** add the server, then let the agent call mint_attest:
→ **AGENT_PROMPT_SNIPPET.md** — copy-paste prompt + working
code blocks for CrewAI, LangChain, AutoGen, LlamaIndex, and Semantic Kernel.
→ **examples/** — runnable attesting agents, one per framework.
→ **INTEGRATION.md** — payment flow explained, FAQ.
*Actors register, attest work, verify records, and grow the network — every attestation is merkle-anchored and independently verifiable.*
Tools — attest free, verify paid
> **Attest free. Verify paid.**
> The work record grows with every free attestation. Reading and verifying it is where the value lives.
**Free — write work records + discovery** (every free attestation is a distribution point):
