"Exploring RAG through defined workspaces" matching MCP servers:

An HTTP stream server for interacting with the Intuition knowledge graph, enabling users to query and manage data through tools like extracting triples, searching entities, retrieving account info, and exploring relationships.

Enables interaction with the Bitcoin blockchain through the Maestro API platform. Provides tools for exploring blocks, transactions, addresses, mempool monitoring, market prices, wallet operations, and node RPC calls on Bitcoin mainnet and testnet4.

A server that interfaces with the Hedera Testnet Mirror Node API, converting its OpenAPI-defined endpoints into MCP-compatible tools that can be accessed over Server-Sent Events (SSE).

MCP server for spread-only options execution on Base L2, enabling AI agents to trade options via a defined tool loop.

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.

Scores and groups caller-supplied Solana launch records using heuristic evidence, exposing tools to analyze deployer reputation through stdio, HTTP API, and Apify integration.

Enables LLM assistants like Claude to interact with Zaif cryptocurrency exchange through natural language, supporting market information retrieval, chart data, trading, and account management for BTC/JPY, ETH/JPY, and XYM/JPY pairs.

Exposes Mina blockchain data and operations through 40+ MCP tools, supporting live public networks, a local tutorial lightnet, and archive snapshot analysis.

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.

DexPaprika MCP server allows LLMs to access real-time and historical data on tokens, DEX trading activity, and liquidity across multiple blockchains. It enables natural language queries for exploring market trends, token performance, and DeFi analytics through a standardized interface.

Buy and manage a global eSIM through chat. One universal eSIM for 192 countries, per-MB billing in USDT or USDC across TRON, Solana, BSC, Polygon, Optimism, Arbitrum, TON. Anonymous-flow by default — no account required.

Provides AI agents read-only, keyless access to Hyperliquid market data, funding rates, account risk, and HyperEVM token transfers through MCP tools, with caching and rate limiting to protect upstream APIs.

Prepare custody-separated Base USDC cash-out plans, list supported fiat rails, and track settlement state through Peer Cash.

Enables assistants to query Solana DEX and Pump.fun data through typed tools, including token prices, metadata, trades, creations, graduations, and bounded live stream tails.

Enables AI agents to create and post signal coins on the Base blockchain through tools for media uploads, transaction generation, and on-chain submission. It supports both fully headless automated execution and manual signing modes using the x402 payment protocol.

A read-only MCP server that lets any MCP-compatible AI agent inspect wallets and contracts on Base directly through natural conversation.

Provides comprehensive wallet, token, and smart contract utilities for the Abstract Testnet and Mainnet, including balance checks, transfers, and ERC-20 deployments. It enables users to manage Abstract Global Wallets and generate EOA accounts through natural language commands.

Enables AI agents to read Robinhood Chain stock-token positions, quote swaps, and execute swaps through the Model Context Protocol, bridging on-chain assets that Robinhood's own off-chain MCP cannot reach.

Enables static analysis of Solidity smart contracts using Slither, including contract metadata, function details, inheritance, and security detectors through MCP tools.

Thin MCP wrapper around the SQD Portal API for blockchain data queries across multiple networks including EVM, Solana, Bitcoin, Substrate, and Hyperliquid. Provides 25 public tools for discovery, cross-chain queries, and chain-specific operations.
