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.

A Model Context Protocol server that wraps Naver's encyclopedia search API, allowing users to search for information from Naver's encyclopedia through stdin/stdout or HTTP interfaces.

Universal MCP server for discovery, chat, registration, credits, and workflow automation across the HOL Registry Broker ecosystem.

Enables AI agents to interact with the Lido protocol for ETH staking, position management, and governance participation across Ethereum and L2 networks. It provides tools for querying balances, simulating transactions, and executing complex workflows like withdrawals and DAO voting through a safety-first interface.

Free MCP server for x402toll.com, enabling AI agents to discover and use verified, pay-per-call calculators with free previews and hash verification, supporting payments via x402 protocol on Base.

Exposes Base mainnet chain query tools over MCP, letting clients fetch an address's native balance and current gas fee estimates (slow/standard/fast urgency) from an upstream HTTP API. Paid tools are gated by x402 micropayments settled through the CDP facilitator, with a free health check and a documented free-trial allotment.

Hosted, API-key-free MCP server that enables AI agents to interact with the Ens protocol via deterministic tool mappings to real endpoints.

Read-only on-chain query surface for the AgentCivics civil registry on Sui — soulbound AI-agent identities, on-chain memories, reputation, refusal records. Hosted, no install, no keypair. For write tools (register, write_memory, record_refusal), install the npm package @agentcivics/mcp-server locally and supply your own keypair.

MCP Server for the Luno Cryptocurrency API

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

Enables LLMs to interact with the AT Protocol ecosystem, including Bluesky, through natural language. Supports public data access without authentication and full write operations with authentication.

MCP server that lets AI agents interact with NIGHTGATE, the Midnight blockchain attestation layer, to anchor documents, verify zero-knowledge predicates, manage disclosure grants, and poll async jobs.

WaxSeal MCP gives AI agents cryptographic identity — verify any WaxSeal fingerprint, check Ed25519 signatures, and gate irreversible actions with human-signed approval tokens before execution. It connects Claude Desktop, Cursor, and Windsurf to the WaxSeal trust network so agents can prove who authorized an action and reject tampered credentials in under a second.

Pre-trade safety for EVM, Solana and TRON: simulates a real buy and a real sell against live liquidity, so a honeypot shows as a sell that fails instead of a vendor score, and audits a wallet's standing approvals across the three chains. Python standard library only, no API key.

Enables LLMs to compile and verify Tolk smart contract code for the TON blockchain.

Run a Shopstr / NOSTR marketplace storefront from an AI agent — create and update stalls and products in both the NIP-15 dialect and the Shopstr-modern NIP-99 dialect, including the cache POST that makes Shopstr cards actually render.
