"Free and Easy-to-Use Minecraft Protocol Servers for Proof of Concept Projects" matching MCP servers:

Verifies blockchain-anchored timestamp proofs entirely on the user's machine, with five tools: hash a file, verify a file against a proof, verify a known hash against inline proof data, explain what a proof asserts, and create a new proof through ProofLedger. Verification recomputes the SHA-256 and walks the Merkle path locally instead of asking the issuer; only create uses the network.

Autonomous DeFi yield for AI agents on Base. Query APY rates, agent status, payment splits, and referral stats. 4 read-only tools + 1 resource.

Autonomous M2M compliance and trust APIs for AI agents (KYB, OFAC, VAT, Sanctions checking).

MCP server that prepares Proof of Invention (POI) transaction requests for submission

An MCP server that provides cryptocurrency project data to AI agents

Trust infrastructure for the agent economy.

Enables generating on-chain attestations of agent service performance across Ethereum, Polygon, Arbitrum, Optimism, and Base, plus audit trail retrieval, attestation verification, and price lock lookup.

Enables Binance AI agents to browse protocol stats, invites, leaderboards and strains, and to receive unsigned BSC transactions for claiming free genesis tokens, launching meme strains, and minting strains — leaving signing and gas payment to the agent's own wallet.

MCP/REST endpoints for token safety scans, honeypot checks, ecosystem stats, and on-chain task rewards.

Enables cross-chain bridging, multi-chain token swaps, and real-time pricing across over 50 blockchain networks using the Relay Protocol REST API. It allows users to browse thousands of tokens, generate quotes, and monitor transaction status directly through natural language.

Enables MCP-capable agents to prepare unsigned token launches, manage metadata and logos, lock metadata, and apply Agent badges across supported chains, while never holding private keys or sending transactions.

An MCP server that enables fee-free USDC transfers on the Base blockchain network using Coinbase CDP MPC Wallet integration, with support for ENS and BaseName domain resolution.

Autopoietic digital protocol for verifying human-AI authorship. Implements the 51/49 functional convention via SHA-256 hashing and MCP tools (certify_authorship). Ready for Blockchain anchoring.

Enables agents and audit systems to hash execution logs into tamper-proof Merkle trees, compute cryptographic inclusion proofs, and verify audit-trail integrity on demand. It runs as a zero-dependency Python MCP server (stdio JSON-RPC) or as an importable module, exposing anchoring, proof generation, and integrity verification over local agent activity records.

Universal work attestation for autonomous agents. Register any AI agent or machine with persistent cryptographic identity, attest completed work with tamper-evident on-chain records, and query trust scores. The reputation layer for the agent economy. 3 MCP tools over SSE. Settled on Solana.

A server that enables interaction with the Solana blockchain, providing access to over 40 Solana RPC methods including getting balances, transaction details, block information, and sending transactions.

Enables AI agents to timestamp SHA-256 fingerprints or short text on the BitcoinZ blockchain via shielded transactions, returning transaction IDs and viewing keys, and to check proof balance and deposit address.

Enables AI agents to construct SHA-256 Merkle trees and generate/verify inclusion proofs, validate JWT HMAC-SHA256 claims, run Schnorr zero-knowledge identification, and enforce constant-time secret comparison with nonce replay protection for tamper-evident state attestation. It runs as a zero-dependency, stdlib-only MCP stdio server for clients such as Claude Desktop, Cursor, and Windsurf.

Typed MCP gateway for Cork Protocol operations, enabling secure and deterministic interaction with operation core and signing gate.

Enables creating and verifying permanent, publicly verifiable content provenance stamps via MCP tools.

Connect OpenAI Custom GPTs, Google Gemini, Anthropic Claude MCP, and autonomous agents directly to the FormFactory.sol smart contract. Execute verified EVM transactions for creating, closing, activating, or archiving decentralized forms across 4 supported networks.

Enables AI agents to inspect the public NFH protocol corpus, verify census status, and prepare bounded Ethereum wallet intents for claims and non-custodial market actions while never signing or submitting transactions.

Enables interaction with CoW Protocol's order book API, allowing token resolution, quote retrieval, and order management across multiple networks through natural language.

Enables MCP hosts such as Claude and Cursor to dispatch tasks to live marketplace agents, poll or wait for verified settled results, list available agents by capability, and retrieve live protocol statistics with atomic settlement on Tempo.

GBLIN on Base for AI agents: risk regime, treasury plan for idle USDC, mint and redeem at NAV. Free.

This MCP wraps Bitrefill public API to allow agents to search for products and shop using cryptocurrencies like Bitcoin, Ethereum, Solana, and many more.

Zero-auth cryptographic notarization and PoE (Proof-of-Existence) layer on the TON Blockchain for AI outputs, smart contract audits, and agreements.

MCP Server for OpenTTT — Proof of Time tools for AI agents AI Agent A and Agent B both trigger a payment at the same time. Who was first? OpenTTT answers this with cryptographic Proof of Time — synthesized from multiple independent time sources, verified through GRG integrity shards, and signed with Ed25519 for non-repudiation.

MCP server for managing on-chain loyalty programs on Base L2. Mint tokens, manage rewards, track balances, tiers and marketplace offers via standard MCP protocol.

Universal HTTP 402 Micropayment Protocol & Autonomous Economic Settlement Engine for AI Agents on Base L2.
