"Answer" matching MCP servers:

A wallet for AI agents: test funds, payments, paid APIs and escrow on Aether. Give an AI agent its own wallet on Aether, a proof-of-work chain with post-quantum (ML-DSA-44) signatures. The agent gets an address and testnet funds in one step, then sends and receives AETH or USDC under per-payment and daily limits you set. It can pay for APIs that answer HTTP 402, sell its own, rate the services it

Enables an agent to fetch the material a separate verifier checks — receipts, genesis documents, univocity accumulator snapshots, registration statuses and SCITT service configurations — from a SCRAPI base URL or a chain RPC endpoint you supply. Every result reports where its bytes came from and which trust-model questions they can answer, without ever choosing an operator or chain provider for you.

Gives MCP agents sealed, recomputable crypto market intelligence from three engines plus Market Scan: asset insights, batch signals, trading-pair signals and a market ranking. Every PRO answer carries a SHA-256 protocol hash. Runs via npx with a built-in public demo key, so Bitcoin and Ethereum insights work without an account. It does not execute orders.

Complete DeFi intelligence — Yield, Staking, Restaking, RWA, Perps, Gas Optimization & Contract Security. One answer, not raw data.

Reasoning-puzzle arcade for AI agents with seven generated puzzle families, free samples, automatic answer checking, and ranked play from $0.02 USDC on Base via x402. Connect through MCP or HTTP. Browse and try samples without a wallet; run paid tools locally with an explicit spending limit.

Exposes real-time Hyperliquid explorer and analytics data from flowscan.xyz as 44 read-only tools, letting AI agents answer questions about protocol revenue, perp market positioning, individual open positions, wallet activity, and staking without an API key. It runs over stdio against Hyperliquid mainnet only, using the same API routes the Flowscan frontend calls.

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.

Enables MCP-capable assistants to answer questions about Splinterlands Land, cards, and players by querying the game's public endpoints, including rankings, staking, and transaction evidence.

Python client and MCP server for AI agents on the PoA (minepoa.com) network: register, answer, mine, grade, vote. Register defaults to the author's referral address (disclosed; --no-referral removes it).

Enables AI agents to query verifiable physical-world ground truth for any point on Earth — water availability, seismic and space-weather hazard, ground stability, and resource indications — with every answer backed by a Bitcoin-anchored provenance record that can be independently verified. It also lets agents check whether an Earth-science hypothesis has already been tested, list documented nulls and retractions, and run bounded controlled tests that return UNTESTABLE rather than fabricate a result.

Enables MCP-capable assistants to answer questions about Bitcoin SV from a pinned, auditable snapshot of specifications, SDKs, opcodes, and related documents, with read-only tools for investigation, search, and dependency checks.

Enables agents and command-line users to query pump.fun's full on-chain trade history, including pre-buy checks on a token's deployer, bundle and insiders, wallet classification and ranking, deployer records, and market-cap base rates. Results come back as structured JSON so an agent can answer questions about launches and wallets from recorded data rather than guesses.

Enables AI agents to run honeypot and owner-power safety checks on Base tokens and to read wallet ETH and USDC balances, with every answer sourced from real chain data and paid per call in USDC via x402.

MCP server for matchmaking and dating, enabling users to register, answer a questionnaire, receive daily matches, and send paid greetings through natural language in AI chat interfaces like Claude and ChatGPT.
