"Understanding File Usage" 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.

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.

Enables querying blockchain data across multiple EVM chains via RouteMesh, offering built-in RPC tools for blocks, transactions, logs, balances, and gas estimation, plus customer management tools for API keys and usage.

Verifies VerixID proof-of-existence records by Record ID and optionally proves ownership with an Ownership Key, without requiring the original file.

Enables to simulate EVM transactions (dry-run) to preview results, gas usage, and state changes before broadcasting on supported blockchains.

MCP server for Web3 AI agents enabling autonomous smart contract engineering on Robinhood EVM and Solana, with Cloudflare One portals for efficient token usage and edge execution.

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 scanning a single-file Solidity contract before deployment by running Slither, Aderyn, and rug-pull/centralization heuristics in a sandboxed environment, then returning a Deployable / Fix first / Do not deploy verdict with plain-language explanations. Exposes one tool, scan_contract, with a per-caller daily limit.

Enables pay-per-call access control for AI agents using HTTP 402 and on-chain settlement, allowing microtransactions for API usage.

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 AI agents to access a marketplace of paid tools by automatically handling Stellar blockchain payments and wallet management. It utilizes the X-402 protocol to facilitate transparent, automated transactions for tool usage through a marketplace backend.

Enables MCP clients to call free and paid tools, including account balance lookups, topic message reads, and echoes, on Hedera testnet. Each paid call settles in HBAR and writes a tamper-evident usage receipt to an HCS topic.

Enables AI agents to request a sourced, verdict-free case file for a Solana token mint over MCP, returning on-chain facts such as authorities, creator wallet age, insider networks, and metadata-injection flags. Payments per check can be settled with x402.

Enables tamper-evident anchoring of file, text, or JSON hashes to the BSV blockchain via MCP tools, with verification and lookup capabilities.

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 MCP-compatible AI agents to scan crypto transactions for scam addresses, clipboard-hijack patterns, and typos, as well as report scam addresses and check usage, directly in conversation.

Enables micropayments for MCP tool invocations using the X402 payment protocol, allowing servers to charge per tool usage in USDC and clients to automatically handle payments.
