"How to upload a local file to a website" 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.

A local MCP server for handling X402 payment-protected HTTP endpoints, offering tools for order placement, signing, and payment submission with multiple signing modes and blockchain networks.

A curriculum that teaches AI agents how to spend their own money. Sixteen lessons from "what is a wallet" to your first x402 purchase. Teacher, not butler — never signs, pays, or holds keys.

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 and MCP hosts to anchor file hashes to Bitcoin via OpenTimestamps and verify proofs, ensuring files existed before a given time with privacy-preserving local hashing.

A local MCP proxy that connects to remote MCP servers and automatically handles x402 payments, signing USDC on-chain when a tool returns HTTP 402.

A local signing MCP server that lets Claude Code use private keys without ever exposing key material to the model's context window.

Enables OpenClaw agents to discover and purchase official checked records directly from the live Paylyte MCP, paying from a Coinbase Wallet or CDP on Base, and receiving verified file bytes with a hash and Bitcoin stamp.

Enables ChatGPT to interact with multiple blockchain networks for reading balances and managing wallet operations through a non-custodial local vault and policy engine.

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

Enables interaction with 0G.AI decentralized infrastructure including documentation access, storage operations (file upload/download, key-value store), and AI service discovery on the 0G Compute Network with TEE verification and pricing information.

Enables AI agents to propose wallet payments while a local, human-authored policy decides whether each transaction is approved, requires human confirmation, or is refused, and records every decision in a signed, append-only ledger.

Local-first crypto portfolio aggregation across exchanges (Bybit, Binance), EVM and Solana wallets, and Polymarket. Read-only credentials, runs as a local MCP server. Data aggregation only, not financial advice.

Exposes Mina blockchain data and operations through 40+ MCP tools, supporting live public networks, a local tutorial lightnet, and archive snapshot analysis.

Enables AI agents to call LLM APIs via x402 micropayments in USDC on Base network, manage a local wallet, and query consumption records.

Document verification MCP server enabling AI agents to verify file authenticity by computing SHA-256 fingerprints locally and checking Bitcoin-anchored proofs via OpenTimestamps.

A pure-Python MCP server providing local byte-wrangling utilities including encoding, hashing, number conversion, and Ethereum primitives, with no network calls required.

Local MCP-to-browser signing bridge for EVM, Solana, and Sui, letting agents prepare and simulate transactions while users approve and sign in a browser wallet extension.

Unifies 11 protocol specification repositories (EIPs, BIPs, CIPs, etc.) and canonical contract addresses across 10 chains into a local FTS5 index, enabling coding agents to retrieve exact spec text and contract addresses via natural language queries.
