"Creating an MCP server that connects to a blockchain" matching MCP servers:

An MCP server that exposes blockchain data as native tools for AI agents, enabling read-only queries like wallet balances and token holdings on Ethereum, Polygon, and Base.

A Model Context Protocol server providing Ethereum blockchain tools, including vanity address generation and Cast command functionality for interacting with Ethereum networks through natural language.

An MCP server that connects Hermes Agent to the Solana blockchain, enabling natural language queries for wallets, tokens, NFTs, transactions, whale movements, and network health.

A Model Context Protocol server that enables natural language interaction with the TON blockchain, allowing users to perform queries for balances, analyze trading patterns, detect hot trends, and conduct forensic investigations on blockchain data.

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.

Publishes a spending-summary tool alongside an interactive HTML view, letting people click a category in the answer to fetch the individual expense records behind that total. Keeps calculations and their supporting evidence together in a single inspectable flow.

Enables AI agents to analyze whether they should send an email, evaluating passive aggression and regret probability with a recommendation heavily weighted toward no.

Enables AI agents to call tools through a security gateway that intercepts requests, enforces deterministic policy and risk checks, blocks or escalates high-risk actions for human approval, and keeps tool credentials and audit logs protected.
