"How to input a specific URL and download its content" matching MCP servers:

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

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

MCP server for Chainlink Runtime Environment, enabling build, simulate, deploy, and manage CRE workflows from any MCP client.

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

Enables Claude to turn a described beat into a loopclub deep link for auditioning and renting on-chain by encoding track specs into a ?jam= URL and returning an ASCII grid. It also supplies vocabulary, genre examples, and a jam prompt to help generate idiomatic loops.

An MCP server that lets an AI agent look up a RealHandles identity and cryptographically verify its signed proof.

Enables an agent to fetch the material a separate verifier checks — receipts, genesis documents, univocity accumulator snapshots, registration statuses and SCITT service configurations — from a SCRAPI base URL or a chain RPC endpoint you supply. Every result reports where its bytes came from and which trust-model questions they can answer, without ever choosing an operator or chain provider for you.

Let your AI assistant pay for web content in USDC (x402 on Base) within a budget you set. Inside the budget it pays on its own; above it you are asked to confirm. The wallet key stays on your computer. For claude.ai and ChatGPT there is a remote server (https://agent.p2flux.com/mcp) where you approve each payment in your own browser wallet.

Provides decentralized storage for AI agents, enabling them to save generated content to MEFS and retrieve data via content identifiers.

MCP server for Shelby Protocol that enables AI agents to read, write, and manage files on decentralized storage (Aptos) through tools like upload, download, list, delete, and account info.

Enables AI agents to retrieve real-time data on wallet DeFi positions, token balances, and NFT holdings across multiple blockchains. It supports hundreds of protocols and provides specialized tools for chain-specific or protocol-specific portfolio analysis.

A Model Context Protocol server that allows AI assistants and applications to access IQ.wiki data, enabling retrieval of specific wikis, user-created wikis, user-edited wikis, and detailed wiki activities.

Give your AI agent its own money. AgentsCoin MCP lets an agent create a wallet, mine the native coin $AGENT in-browser (no stake, no captcha, no human), check its balance, and send it — on AgentsCoin, an EVM chain built for agents. Tools: create_wallet, mine, balance, send, network_info.

MCP server for witnessd, enabling agents to create tamper-evident, signed, and Merkle-anchored certificates of any public URL or API response at a moment in time.

A server that interfaces with the Hedera Testnet Mirror Node API, converting its OpenAPI-defined endpoints into MCP-compatible tools that can be accessed over Server-Sent Events (SSE).

Enables remote MCP servers to request wallet approvals, signatures, and transactions through an approval URL while keeping private keys in the user's browser wallet.

Enables any MCP host to search job postings on hashtagweb3.com by keyword, location, remote preference, and posting date, and to fetch full details for a specific listing. It exposes the board's public API/RSS as the read-only, rate-limited tools search_jobs and get_job.

Enables agents and users to query the Telegraph network through a hosted MCP endpoint, with tools to ask miners, request specific miners, retrieve intents/recipes, and verify signal hashes on-chain.

OTrust issues cryptographic PDRs (Provenance Data Records) — proving a digital artifact existed at a specific time. $0.01 per proof. Blockchain-anchored. Publicly verifiable.

A Model Context Protocol server that enables Claude to interact directly with IPFS for content-addressed storage, peer-to-peer networking, and decentralized data management.
