"Servers that Enhance Productivity" matching MCP connectors:
GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
Remote MCP server for crypto trading signals and the public ledger that scores them, losses included. Read tools: open signals, the signal ledger (matured wins and losses), signals cancelled by the BTC regime veto with the outcome they would have had, market snapshot and ticker for scanned Binance symbols, the scheduled BTC chart read, and news headlines. The public read tools work without a key. With a free API key from ribqa.com: your own bots and strategies, and rate-limited strategy backtests. No tool places, simulates or cancels an order. Free during beta.
Your agent needs markets — prices and fundamentals for listed companies, the filings behind them, crypto, and what the prediction markets put the odds at. **What you can ask for** • "Pull this company's income statement, cash flow and balance sheet for the last 8 quarters." • "What did insiders buy or sell, and when?" • "Snapshot prices for these 50 tickers, then the OHLC history for the three that moved." • "What are the current odds on this event across Kalshi and Polymarket?" • "Screen for companies matching these financial criteria." **How to use it** Point any MCP client at https://mcp.aisa.one/finance/mcp and sign in with OAuth — there is no key to create or paste. 49 tools: prices and snapshots, income statements, balance sheets and cash flows, metrics and ratios, earnings and analyst estimates, filings and line-item search, insider trades, macro interest rates, news, a screener; CoinGecko spot prices, market tables, OHLC, per-venue tickers and trending; Kalshi and Polymarket markets and trades; plus EDINET filings for Japan. **Why this rather than the source** Equities, crypto and event markets behind one account, so a cross-asset question is one conversation. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Read the number here, then ask the same agent what X is saying about the ticker today — without adding a second server. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** https://mcp.aisa.one/marketpulse/mcp · /crypto-market-data/mcp · /prediction-market-data/mcp · /stock-pulse/mcp for one slice each.
Autonomous research agent that pays every source it cites in USDC on Arc via x402 micropayments.
Monetization gateway for MCP servers. Agents call a tool, receive an x402 v2 payment challenge, sign a USDC transfer on Base, and get the result. Payment is verified before the tool runs and settled only after it returns, so failed calls are never charged. Discovery and tool listing are free.
Crypto positioning and macro intelligence for agents — the signal set a trading desk watches, delivered as structured JSON. Multi-venue perpetual funding and open interest across Binance, Bybit and OKX (largest-open-interest perp per venue, thin venues excluded), Ethereum exchange whale flows, Bitcoin network health, DeFi TVL and stablecoin supply, Fear & Greed, and BTC/ETH/USDT dominance as a risk-on/risk-off regime filter. Plus the macro backdrop that actually drives crypto: Fed funds rate, 2Y
Read-only crypto research skills that check a price, RSI and ATR against independent sources.
Prices and rates that state when they were observed, so you know what you are trusting.
61 x402 pay-per-call tools that chain: each answer names the next call. No API key, no account.
Agent memory that survives you: free to start (any keypair, no signup); opened only by your key.
OpenSpender gives your agent an allowance, not your API keys: one self-custodial USDC wallet that pays per request for web search, frontier models (Claude, GPT, Gemini, Grok), image and video generation, and a growing catalog of x402/MPP machine-payable APIs — every call priced before it's paid and capped by budgets you set.

- Agent WalletOAuth via extensionxyz.fd.wallet-mcp
Agent Wallet is a non-custodial wallet that lets AI agents hold and move crypto without ever handling a private key. Keys are generated and used inside an AWS Nitro Enclave, so neither the agent nor the model can read them. Supports EVM, Solana, Bitcoin and Sui, and pays x402 endpoints directly.
Your apps, skills, MCP servers and keys from ahel.ai, served to Claude, ChatGPT, Cursor and Codex.
