"Agentic RAG: Understanding or Exploring Its Meaning and Applications" matching MCP servers:

MCP server for managing Bitcoin, Liquid Network, and Lightning wallets through AI assistants, with unified seed support, secure encrypted storage, and both CLI and tool interfaces.

Non-custodial payment engine for AI agents supporting BTC, ETH, USDT, USDC, XRP, XMR, and ZEC. Exposes wallet, invoice, and payment tools over MCP with per-agent spend limits, plus x402 pay-per-call support.

A self-hosted decision engine that sits between an AI agent and blockchain execution. Agents submit a proposed action, Guardian returns an explainable ALLOW / WARN / BLOCK before anything gets signed or broadcast.

Exposes an EVM wallet to AI agents via MCP, using AWS KMS for HSM-backed signing and a deny-by-default policy engine for secure DeFi transaction approvals.

MCP server that exposes T54 x402 seller SKUs from OpenAPI as tools: contract triage, audit, and monitoring plus T54 commerce tools. HTTP 402 invoices are paid via x402_broker_client (XRPL / Base USDC depending on env); stdio for Cursor/Claude, Streamable HTTP for hosted use.

Enables read-only, keyless queries of timestamped, definition-backed data about AI agent payments and activity on Base, including rankings, agent records, detections, metric histories, and evidence-pack pricing, from MCP clients or the terminal.

AI-driven portfolio dashboard and MCP server for the Casper blockchain, enabling wallet monitoring, validator staking analysis, RWA compliance checks, and on-chain transaction generation.

Policy-gated MCP execution for AI agents—ShadeGuard, x402, signed receipts, no custody. 16 tools, 18 chains.

This MCP wraps Bitrefill public API to allow agents to search for products and shop using cryptocurrencies like Bitcoin, Ethereum, Solana, and many more.

Wallet-funded MCP client for six paid Utilia tools: Solana priority fees, transaction diagnosis and simulation, token-risk checks, PDF-to-Markdown, and audio normalization over x402. MIT-licensed and installable from npm.

Self-hosted MCP server enabling AI agents to manage EVM wallets, check balances, swap tokens, and securely execute transactions via 1Claw Intents without exposing private keys.

MCP server for Chainlink Runtime Environment, enabling build, simulate, deploy, and manage CRE workflows from any MCP client.

Pay-per-use contextual guidance for AI agents. When an agent loses direction, it describes its state, pays 21 sats via Lightning or Arbitrum ETH, and receives its original purpose stripped of noise.

Algorand ecosystem MCP server that identifies applications, assets, protocols, and resolves .algo names, providing meaning rather than raw chain data.

Non-custodial x402 tip jars for the agentic web, enabling USDC tips via a hosted MCP tool for agents.

Enables users to verify whether an ERC-8004-registered agent is currently reachable by resolving its on-chain registration and performing a live MCP handshake, returning verdicts such as REGISTERED_UNREACHABLE or AGENT_NOT_FOUND.

Checks live x402 routes across Base, Solana, and Algorand before agents spend. $0.003 USDC settles only for a valid live eligible route; normal typed misses are not settled. Free preview and validate tools. Seller payment is separate; the agent keeps its wallet. Optional signed route-binding receipts support buyer-side checks.

Provides read-only tools to query live Polymarket prediction-market data via the public Gamma API, enabling search, browsing, and detailed market and event information.

Rug pull risk scores and on-chain forensics for memecoins on Solana, Ethereum, Base and Robinhood Chain - launch-bundle detection, funding-origin tracing, deployer history, insider networks and whale flow. 15 read-only tools.

Enables AI agents to make pay-as-you-go AI inference requests through x402 with automatic Solana USDC payments, no API keys or registration, while enforcing configurable spending limits.
