"How to use or perform actions in Apple Calendar" matching MCP servers:

A stdio MCP server that gives agents read-only access to Ethereum public data scraped from etherscan.io with no API key, covering first funder, address metadata, ERC20 holdings, token holder lists, transaction history and transaction details. It also answers standard Ethereum JSON-RPC calls such as eth_getBalance, eth_call, eth_getTransactionReceipt and block lookups, and supports batched NDJSON requests with resumable streaming results.

Generates MCP servers from smart contract ABIs, enabling Claude to interact with any Ethereum contract via natural language commands.

Lets AI agents check whether an EVM wallet address carries an EIP-7702 delegation across eight chains (Ethereum, Base, BNB Chain, Arbitrum, OP, Polygon, Gnosis, Unichain) and learn how to obtain a deeper paid report with delegate bytecode heuristics and risk levels. Read-only, never touching private keys or seed phrases.

Teaches AI coding agents how to reason correctly about MetaMask Embedded Wallets / Web3Auth architecture, SDK choice, key derivation, auth flows, and common integration pitfalls.

Cross-chain bridge aggregator MCP server for AI agents. Compares routes across LI.FI, deBridge, Relay, Across and Squid to find the best rate. Use when an agent needs to bridge or swap tokens between EVM chains, Solana, or Cosmos. The aggregator of aggregators.

Enables AI assistants and agents to perform read-only lookups of dated on-record facts about agents, wallets, and endpoints, including evidence levels and history, so they can assess what is known before paying or relying on them.

A comprehensive MCP server providing unified access to the Hedera DeFi ecosystem, including SaucerSwap, Bonzo Finance, and Stader. It enables AI assistants to perform real-time data analytics and prepare or execute transactions across multiple decentralized finance platforms.

Enables users to manage API keys and perform Aptos Build actions through MCP-compatible interfaces like Claude and Cursor. This server facilitates development workflows on the Aptos blockchain by integrating directly with the Aptos Build platform.

Enables AI assistants to prepare and execute onchain wallet actions, including balance checks, name resolution, swaps, bridges, transactions, and DeFi skills, with popup approval by default or scoped ERC-7710 delegated execution when opted in.

Enables AI agents to perform Web3 creator monetization actions like tipping creators, buying digital products, and managing memberships through natural language.

Enables MCP clients to use an ERC-4337 smart account with session keys to check wallet status, send ETH or ERC-20 tokens, call allowed contracts, and manage approval requests within on-chain spending limits.

Enables AI assistants to query evidence-backed DeFi yield data across roughly 17,000 pools — what each pool pays, whether yield comes from base or reward tokens, and how rates have moved over 7/30/90 days. Every figure is dated and linked to its source, and access is read-only without touching wallet keys.

Enables users to inspect Solana token mint accounts, preflight transfer actions, and verify outcome receipts without holding any keys or signing transactions.

Enables agents to perform on-chain intel and operations on Robinhood Chain, including search, charting, wallet tracking, analytics, and preparing pons launches signed in Phantom.

Enables users to inspect Robinhood Chain assets and contracts, construct and review USDG/Stock Token exchange and data-signing decisions, and request approval for those actions in Robinhood Wallet. It maintains local records of received hashes and actual results while keeping keys and transaction authorization under user control.

Enables ChatGPT and Codex to request public keys, prepare and sign exact Nostr events, encrypt or decrypt NIP-04/NIP-44 payloads, and publish with per-relay acknowledgement, while the private key stays in the user's Alby, nos2x, or remote NIP-46 signer. Every operation is queued for local browser approval, with one-use signing intents and verification before anything is broadcast.

Enables AI agents to perform private, keyless web search and resolve Moshpit names or view live network statistics through MCP tools.

Enables AI agents to safely sign and send Solana transactions under a policy, with automatic signing for in-policy actions, air-gapped human approval for escalations, and rejection of disallowed transactions.

Enables AI agents to perform Lido staking operations (stake, unstake, wrap, unwrap, check balances/rewards) via natural language.

A minimal demo of the x402 payment protocol protecting an MCP tool endpoint, showing how to charge for MCP tools using real 402 rejections and testnet payments.

mcp server that allows to do actual actions related to solana first version adds knowledge about RPC methods and how to call them

A Model-Context-Protocol server enabling users to perform basic operations on Solana and Ethereum blockchains through simple RPC endpoints.

Enables AI agents to generate and persist a self-sovereign did:key identity, sign claims about their actions as Ed25519 attestations, verify those attestations offline without any registry or network access, and compute an auditable reputation score from a ledger of events. All four operations are exposed as MCP tools so an agent can manage its own identity and prove its history during a session.

An MCP server that enables AI agents to perform SM2-based identity binding, generate and verify SD-JWT verifiable presentations, and use SM2 cryptographic operations with local communication and national cryptography encryption.

Enables AI agents to pay per tool call in USDC via the x402 micropayment protocol, with no API keys or subscriptions required.

Rescues USDC, USDT and USDG from wallets with no gas. Agents check a wallet for stuck or frozen stablecoins, quote a send or a swap into the gas coin, collect the wallet signature and track the transfer. Base, Arbitrum, Ethereum, Polygon, Avalanche, BNB Chain, HyperEVM, Robinhood Chain, Solana and Tron.

Enables AI agents to read and bid on a paid message slot on Solana, with enforced spend limits, dry-run proposals, and an append-only audit log for every write.

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.

Trust infrastructure for AI agents on Base. DEX Spread Oracle (live Uniswap V3 prices), on-chain escrow, insurance pool, and collective knowledge base. 7 smart contracts. Pay-per-query via x402 micropayments in USDC.
