"Understanding Feedback Enhanced Concepts or Technologies" matching MCP servers:

This project implements a Model Context Protocol (MCP) server that combines the power of Dune Analytics and Blockscout APIs, providing comprehensive blockchain data analysis capabilities for LLM agents and MCP clients.

On-chain crypto indicators (EMA, RSI, VWAP, Bollinger) via Chainlink oracles.

A Solana blockchain interaction server that allows AI tools to query blockchain data using natural language, access structured token information, and generate human-readable explanations of complex blockchain concepts.

Exposes read-only ERC-8004/ERC-8183 resources and preparation tools for deliverable hashes, evaluation reason hashes, and ERC-8004 feedback payloads.

Enables static security audit of Solidity smart contracts by analyzing source code or deployed bytecode for vulnerabilities, providing risk scores and detailed findings.

MCP server for local transaction signing across EVM, UTXO, Tron, and XRP blockchains, with no network calls or API keys required.

Enables cross-chain swap execution across 12 venues and 16 chains, including native Bitcoin as source or destination, with tools for quoting, execution, status, and health checks. No signup, API key, or protocol fee required.

Enables cross-chain swap queries and unsigned transaction building for Mayan Finance, supporting Solana and seven EVM chains via MCP tools, without holding private keys or signing transactions.

Decodes Ethereum calldata and returns a safety verdict with plain-English explanations of what the transaction does, flagging dangerous actions like unlimited approvals or gasless permits.

Deploys AI agents on-chain into the Metaplex Agent Registry on Solana, minting Core assets with EIP-8004 identity. Supports self-custodial signing via server keypair or external wallets, with devnet support for free rehearsal.

Cross-chain bridge aggregator MCP server for AI agents. Compares routes across LI.FI, deBridge, Relay, Across and Squid to find the best rate. Use when an agent needs to bridge or swap tokens between EVM chains, Solana, or Cosmos. The aggregator of aggregators.

Generate crypto QR codes (BTC, ETH, SOL, USDC, USDT, EURC) and manage payment sessions from Claude Desktop or any MCP client. Non-custodial, free.

Provides local access to Aztec documentation, examples, and source code via cloned repositories, with optional semantic search for enhanced querying.

MCP server for AI agents to create and manage P2P escrow deals on Base (ETH or ERC-20).

Enables AI agents to batch-send ETH or ERC-20 tokens to multiple recipients in one transaction on Base, drastically reducing gas costs.

A keyless MCP server that builds unsigned Uniswap v3 liquidity-position transactions and optionally simulates them via eth_call; it never holds keys or signs.

The safety layer that checks a DeFi transaction or token before your agent (or you) signs — on Base L2.

Lets AI agents discover, pay for, and call any HTTP API per request using USDC, with gasless nanopayments and no API keys or accounts needed.

Enables AI agents to explain DigiDollar transactions recorded on DigiByte, including mints, transfers, redemptions, amounts in cents, lock tiers, burns, and collateral releases, using bundled fixtures or an optional live explorer.

On-chain Solana token safety for trading agents — traces coordinated wallet funding, same-block Jito bundles, serial-rug deployers and live coordinated dumps into one Exit-Liquidity Risk verdict before a swap. Free tier, then $0.02 USDC/query via x402.
