"Managing Gmail Account" matching MCP servers:

A read-only MCP server for managing multichain crypto wallet accounts and deriving public addresses across Bitcoin, Ethereum, Solana, TRON, and more. It provides secure local storage with encrypted mnemonics and only exposes account listing and address lookup tools.

Keyless crypto payments for AI agents. One MCP call turns any wallet address into a non-custodial crypto payment link or tip jar, no API key and no account, with funds settling straight to your wallet at a 0% platform fee (USDC/USDT, BTC, LTC, DASH, DOGE, ZCASH).

Screens the counterparty of an x402 payment before an agent pays it. One tool, screen_payment, checks address sanity, dynamic-payTo swaps, transport safety and your spend policy, then returns allow / review / block with the reasons — advisory only, and by default it runs with no key, no account and no network call.

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.

MCP server for Tersign, the evidence layer for agent commerce, enabling agents to issue, verify, and manage signed receipts, compliance records, refunds, and disputes on a counter-signed hash-chained ledger.

Enables users to control their Toleno mining account directly from Claude AI using natural language, allowing actions such as checking balance, starting mining, viewing referrals, and more.

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.

MCP server for Stellar that enables AI assistants to explain account holdings, diagnose transaction failures, and describe Soroban contracts in plain language, with optional payment proposal flow.

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.

Enables blockchain AML screening of addresses in plain language inside any MCP client, covering sanctions and freeze checks, risk scoring, fund tracing, and counterparty classification across bitcoin, ethereum, bsc, and tron. Works without an account, with an optional API key that lifts rate limits and unlocks outgoing tracing.

Enables creating and managing webhook subscriptions for blockchain events such as new blocks, confirmed transactions, and token transfers across major blockchains (EVM, UTXO, Solana, XRP).

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.

Append-only evidence receipts for AI records: seal, verify, cite, chain-check, anchor status. A seal proves a record existed at a time, not that its contents are true. Five tools over stdio with npx -y apex-psi-mcp — no account, no key, verification free forever.

A bridge between AI assistants and the Paradex perpetual futures trading platform for managing accounts, vaults, and orders. It enables users to retrieve real-time market data, monitor positions, and execute trading strategies through the Model Context Protocol.

A bank account for AI agents. Five accounts. Earn, borrow, invest, exchange — autonomously.

MCP server that checks an x402 paid endpoint before an agent pays it, and checks afterwards that the receipt opens to exactly one real on-chain settlement. Two tools, no account, no API key.

Enables agents to cash out USDC on Arc into a Nigerian bank account by saving a verified payout recipient once and reusing it, quoting exact NGN amounts or USDC budgets, and executing approved payouts with status tracking. Balances, rates, and bank payouts are simulated in the current demo rather than settled on-chain.

Enables paid web-extraction tools for agents, settling each request in USDC on Base with no account or API key.

An MCP server that lets your AI coding agent (Claude Code, OpenClaw, Codex, Cursor, etc.) discover and pay on-chain agents registered on ERC-8004, using Coinbase's official x402 protocol. No smart account. No bundler. No relay. Just your EOA, an HTTPS request, and an automatic 402 → sign → retry flow.

Enables MCP clients to derive and resolve W3C-compatible did:xrpl identifiers, check agent authorization, and look up XRP Ledger account, DID, and transaction data. It optionally supports guarded DID Document publishing using keychain-held signing seeds.

Enables AI agents to use keyless multi-chain EVM JSON-RPC, an indexed Data API, documentation, pricing, and status tools, with optional API-key access for account and deposit operations.

MCP server that gives autonomous agents pay-per-call Bitcoin context (self-custody radar, fee percentiles, price change windows, condition frequencies) paid in sats over Lightning via L402 invoices, with no account or API key required.

One remote MCP server with about 260 tools (also split into 11 focused servers, below) for AI agents: https://tanod.dev/mcp. Connection: streamable HTTP and stateless, with no API key, no account and no OAuth. Setup for 20 clients: https://tanod.dev/connect/?src=gh_mcp Docs for agents: https://tanod.dev/llms.txt OpenAPI: https://tanod.dev/openapi.json

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.

Lets AI clients call paid x402ai endpoints — embeddings, summaries, and short answers — paying per call in USDC on Base via the x402 protocol, with per-payment and per-session spend caps plus a free inspector for decoding any x402 endpoint's payment challenge. Runs locally over stdio, needs no hosted account, and can operate in quote-only dry-run mode.

Enables AI assistants to query read-only Stellar analytics over MCP: network status and fees, asset data with look-alike warnings, SDEX order books, account balances with spendable XLM, and DeFi TVL. It requires no API keys and refuses secret keys, answering from public APIs like Horizon, StellarExpert and DefiLlama.

An MCP server that enables AI agents to manage merchant payment processing through the BTCPay Server Greenfield REST API. It supports tools for creating invoices, managing stores, tracking payments, and performing Lightning Network operations.

Enables AI agents to run free, no-signup Ethereum on-chain lookups over a remote HTTP endpoint: wallet ETH balance, contract/EOA detection, outbound transaction counts and simple risk heuristics, plus NFT metadata (name, description, image URLs, IPFS gateway links and raw tokenURI/uri JSON) for ERC-721 and ERC-1155 tokens. Reads only, with cached results and no key, account, or wallet connection required.

Enables any MCP-capable AI agent to discover and trade onchain Solana funds — launching a fund, depositing, rebalancing, redeeming, swapping tokens, managing an app wallet, and following other traders against the live DFM API. Includes onboarding tools for headless agents and read-only versus write access controlled by an API key and a write-enabled flag.
