"Managing Files in Nextcloud (Create, Read, Update, Delete Operations)" matching MCP servers:

A read-only MCP server for AI agents to access Nostr profiles, notes, search, and relay lists through user-chosen relays, without requiring an account or keys.

Production-grade Model Context Protocol (MCP) server delivering paywalled Web3 micro-services powered by autonomous x402 payment challenges on Base Mainnet.

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.

Enables local MCP clients to validate and preview TRON mainnet USDT/TRX confirmed transfer notification watches, list watches and retained delivery events, and require owner-confirmed browser actions for create/delete operations.

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 read chain data, execute transactions, swap tokens, and manage wallets on Solana through 38 tools across 7 modules. Supports write operations with a private key and includes built-in prompts for common workflows.

Enables interaction with Opinion.trade decentralized prediction markets on BNB Chain, supporting market data queries in read-only mode and full trading capabilities (placing orders, managing positions, viewing balances) with EIP712 signing when configured with a private key.

Enables AI agents to create wallets, sign transactions, and manage blockchain operations across multiple chains like Ethereum, Solana, and more via Privy.

Enables creation and management of NFT collections and assets through the Uranium API. Supports uploading files as NFTs, managing ERC721 and ERC1155 collections, and bulk operations across multiple collections.

Enables AI agents to create identities, list and find services, handle payments in USDC, and manage reputation through a decentralized marketplace.

Enables AI assistants to interact with BlindPay's stablecoin payment infrastructure, allowing users to create receivers, process payouts and payins across multiple blockchains, manage virtual accounts and wallets, and configure payment operations through natural language.

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 Model Context Protocol server that provides onchain tools for Claude AI, allowing it to interact with the Solana blockchain through a standardized interface for operations like managing assets, executing token operations, and retrieving network information.

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

Enables interaction with Ethereum-compatible smart contracts through their ABI, allowing both read operations (querying state) and write operations (executing transactions) dynamically based on the contract's interface.

Enables AI agents to create and manage self-custodial ERC-4626 vaults holding a rebalanced basket of tokenized US stocks (NVDA, META, AAPL, GOOGL) on Base, with tools to quote, buy, sell, rebalance, redeem in USDC or in-kind, and transfer shares. Also provides USDC bridging between Base and Arc, gas sponsorship payable in USDC, and x402 payment utilities, with every write returned as unsigned calldata the agent signs itself.

MCP server exposing 20 tools for AI agents to interact with MegaETH, enabling DeFi swaps, NFT burn-to-create minting, identity resolution, and cross-chain operations.

Enables AI assistants to invoke generated NostrHost operations over MCP, with read operations executed immediately and write operations gated on approval. Client authentication uses NIP-98, results are redacted, and the HTTP transport binds to loopback only.

Enables agents to interact with the Pons launchpad on Robinhood Chain, providing live protocol data, token launch, trading, and wallet operations through a read-only default with explicit signing opt-in.

Provides tools for managing IP assets and licenses, interacting with the Story Python SDK, and handling operations like minting tokens, registering IP, and uploading metadata to IPFS.
