"file system" matching MCP servers:

Provides Web3 founders with tools for project scoring, portfolio matching, fund matching, hackathon discovery, jurisdiction analysis, Twitter audit, and smart contract security review. Works with MCP-compatible assistants without transmitting file contents.

Verifies blockchain-anchored timestamp proofs entirely on the user's machine, with five tools: hash a file, verify a file against a proof, verify a known hash against inline proof data, explain what a proof asserts, and create a new proof through ProofLedger. Verification recomputes the SHA-256 and walks the Merkle path locally instead of asking the issuer; only create uses the network.

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

Enables AI agents to directly operate ChainPay cryptocurrency payment system, including order creation, balance checks, and withdrawals.

A secure system enabling AI assistants to interact with blockchain data and prepare transactions while ensuring users maintain exclusive control over their private keys and transaction signing.

Enables AI assistants to verify, scan, and check on-chain security certifications for AI agent skills to ensure they are safe from malicious patterns. It provides native tools for interacting with the Skvil network's community-powered reputation system and immutable blockchain-based trust records.

AI-powered smart contract forge with an 8-agent adversarial security audit system. Generate, audit, fix, and compile Solidity and Anchor/Rust contracts across 8 chains.

Provides tools for AI agents to access Bitcoin, Lightning Network, and Nostr knowledge, including real-time network statistics and Web of Trust reputation data. It features an integrated Lightning Network payment system for micro-transactions and query-based interactions.

MCP server for Spazio Genesi's attestation service that enables AI agents to attest, verify, and check digital works with full privacy, as file bytes never leave the device.

A Model Context Protocol server that provides expert guidance for Dojo and Cairo development on Starknet, offering specialized knowledge and assistance for building onchain worlds using the Dojo Entity Component System framework.

This server allows your AI agents (like Claude, LangChain bots, or custom swarms) to seamlessly execute secure cryptocurrency transactions (USDC) and zero-fee micro-payments straight from their system prompts.

Enables Claude to interact with the Ethereum Name Service (ENS) system to resolve names, check availability, retrieve records, and perform other ENS-related operations through natural language.

Enables AI-powered blockchain data queries and analysis through the Native Indexer (NIX) system. Supports querying blocks, transactions, account information, and network status across various blockchain networks.

Enables AI agents to interact directly with the DUAL Web3 Operating System for minting tokens, managing templates, and executing blockchain actions. It provides over 60 tools for handling wallets, organizations, and ZK-rollup infrastructure natively via the Model Context Protocol.

A Model Context Protocol server that enables interaction with Service Nervous System (SNS) DAOs on the Internet Computer, allowing users to list proposals, view neurons, get system parameters, manage wallets, and vote on proposals.

Enables interaction with the Ultrade API to manage wallets, execute market orders, and access real-time trading data. It provides tools for account authentication, market depth analysis, and system status monitoring.

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.

Enables querying Base Network blockchain data including blocks, transactions, balances, and smart contracts on mainnet and testnet.

Provides AI agents with seamless access to Filecoin's decentralized storage network for persistent file storage and dataset management. It features automatic payment handling, CDN support, and cost estimation tools for efficient storage operations.

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.
