"A multifunctional research MCP server for a deep researcher subagent" matching MCP servers:

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

MCP server exposing ATLAS research capabilities: live tokenized stock market data, on-chain source-of-truth reads, and published research atlases. Connects to MCP clients over stdio with no API keys required for public testnet endpoints.

Provides AI agents with research tools for AI agent ecosystem analysis, DeFi protocol analysis, and general market research.

Exposes fourteen read-only tools over the HEY Research public API, letting assistants look up Robinhood Chain projects, builders, shipped work, relationships and market context, with each answer tagged FACT, DERIVED or UNKNOWN and unmeasured fields omitted rather than zeroed. Runs over stdio or hosted Streamable HTTP, and gives no trade instructions.

A stdio MCP server that queries Commonware blockchain research via NotebookLM, enabling users to ask research questions, get code-backed implementation suggestions, search reference repositories, and validate documents against source code.

MCP server providing real-time crypto prices (Chainlink + Binance), Polymarket prediction market data, deep web research, and JS-rendered web scraping. All services available via x402 Solana micropayments.

Enables AI agents to inspect the public NFH protocol corpus, verify census status, and prepare bounded Ethereum wallet intents for claims and non-custodial market actions while never signing or submitting transactions.

Enables live market data lookup and search for tokenized stocks, ETFs, commodities, bonds, and real estate on Robinhood Chain, plus broader DEX token discovery, including price queries, market ranking, and movers.

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

Enables AI agents and any MCP client to perform read-only token research on Robinhood Chain through GMGN, covering launch discovery, launchpad screening, token lookup by name or symbol, due diligence packets with a deterministic research score, OHLCV charts, comparisons, smart-money/KOL trades, market signals, and daily briefs. It exposes no swap, order, signing, or wallet tools, keeping every output as research input for a human decision.

Read-only MCP server for investigating Polymarket wallets, markets, and cross-wallet patterns using 21 tools backed by public APIs and an optional SQLite cache.

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.

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.

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

A read-only Model Context Protocol server for the Thru blockchain alphanet, enabling account queries, transaction status, program events, name service resolution, faucet status, and network health via the official @thru/sdk.

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

Enables users to compare current Aerodrome veNFT voting positions, bounded claimable rewards, and selected pools' voting evidence on Base against a saved local baseline, with retryable, atomically stored change reports. All tools are read-only on chain, requiring no keys, signing, or transactions.

Read-only MCP server for querying DERO blockchain — blocks, smart contracts, transactions, network info. Privacy-first, runs locally.

A read-only MCP server connecting AI agents to MTRKR wallet intelligence on MegaETH, enabling wallet portfolio, DeFi positions, security scanning, and transaction analytics.

Provides pay-per-use tools for AI agents like web screenshots and crypto intelligence using automatic USDC micropayments on the Base network. It simplifies access to premium APIs by handling blockchain transactions automatically when a payment is required.
