"Feature Implementation Planning Tools for Existing Projects" matching MCP servers:

A comprehensive toolkit for Ethereum blockchain analysis within Claude AI, enabling contract auditing, wallet analysis, profitability tracking, and on-chain data retrieval.

23 tools for AI agents working with Nostr Open source. No API key. No account. NIP-46 remote signing Publish notes, reply, react, repost Encrypted DMs (NIP-04 + NIP-44) Fetch events, profiles, social graph

MCP server for managing TON blockchain sites, deployments, DNS, and storage via the Resistance Tools platform.

Provides Clockchain's verified-time primitives, notarization, smart-contract scheduling, audit trails, and agent identity verification to any MCP client.

Enables natural language interaction with the Avalanche blockchain through AI assistants, allowing users to execute Avalanche CLI commands and AvalancheJS API operations without technical knowledge.

A production-ready MCP server that wraps the Kxcoscan blockchain explorer API into structured endpoints for AI agents. It enables users to query wallet balances, transaction histories, token transfers, and contract details via natural language.

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

Solana token risk-scoring MCP server for AI trading agents — 0-100 safety score, on-chain insider wallet cluster detection, mint/freeze authority checks, and historical risk data via 3 tools.

A server that enables interaction with the Solana blockchain, providing access to over 40 Solana RPC methods including getting balances, transaction details, block information, and sending transactions.

Enables AI clients to interact with the Rootstock (RSK) blockchain through wallet management, balance queries, token transfers, smart contract deployment and verification, and transaction tracking operations.

A toolkit that integrates with the Sui blockchain, allowing Claude to request test tokens through a testnet faucet tool when users provide their wallet addresses.

Identity + memory layer for AI agents on the Emercoin blockchain — read open, write via GitHub OAuth

Enables AI assistants to interact with Sui Network through tools for balance checks, transfers, swaps, staking, and more.

Enables on-chain attestation of any content onto the DigiByte blockchain, providing permanent, timestamped, tamper-evident proofs. Allows AI agents to notarize their outputs or verify attestations using only the blockchain.

Gives AI agents a verifiable identity using Digi-ID passwordless authentication on DigiByte, enabling them to prove who they are by signing challenges without revealing private keys.

A bridge that enables AI language models to publish content to the Nostr network by implementing the Model Context Protocol (MCP).

A remote MCP server that links World ID 4.0 sessions to AI assistants, enabling verified human authentication and tools for claiming Founding Human places, accessing human grants, and interacting with a verified human wall.

A Model Context Protocol server that enables Claude AI to interact with the Solana blockchain, allowing it to execute transactions, query accounts, manage wallets, get price predictions, trade tokens, and access various blockchain data sources.

9 tools, Lightning-gated. Pay per call. For agents that need verifiable signed actions with an audit trail. Nostr event signing via daemon Publish events to relays Create Lightning invoices Action receipts — signed proof of agent actions Identity attestation

Enables AI agents to discover, call, and pay for existing HTTP APIs over MCP with x402 paywalls, non-custodial settlement, and no code changes to the backend.
