Related MCP Connectors
MCP server connecting AI agents to 100+ apps (Gmail, Slack, Notion, GitHub) via one-click OAuth.
- UnifAPIOAuthcom.unifapi
Hosted MCP server for live public-data APIs and Skills for AI agents.
Docs: https://docs.keenable.ai/mcp-server Keenable is a free, remote MCP server that gives agents access to the web index. Search the web with ranked results and date/site filters, then fetch any indexed page as clean markdown. Works out of the box with no account or API key.
Your agent needs live data — a competitor's traffic, who to contact there, what people are saying, what Google and ChatGPT answer about you, a company's filings. Normally that is six vendor accounts, six sets of keys and six SDKs. This is one URL. **What you can ask for** • "How much traffic does stripe.com get, where does it come from, and who competes for the same keywords?" • "Find 20 Series-B fintech companies in Germany and the heads of marketing there, with emails." • "Does ChatGPT mention our brand when someone asks for the best CRM — and what does it cite?" • "What is X saying about $NVDA today, and what did the stock actually do?" • "Search the web for this, then scrape the three best pages into markdown." **How to use it** Point any MCP client at https://mcp.aisa.one/mcp and sign in with OAuth — there is no key to create or paste. Then just ask: the agent calls search to find the right operation and use to run it. **Why this rather than the source** 26 sources behind one account and one bill — DataForSEO, Semrush, Ahrefs, Similarweb, Apollo, X/Twitter, Instagram, Reddit, Pinterest, YouTube, Tavily, Exa, Perplexity, Firecrawl, CoinGecko, Kalshi, Polymarket, AgentMail and more, 580+ operations. tools/list returns five tools, not 580, so the introduction does not eat your context window. **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** One slice at a time: https://mcp.aisa.one/seo/mcp · /finance/mcp · /social/mcp · /search/mcp · /sales/mcp · /mail/mcp · /gtm/mcp, or a single provider like /twitter-api/mcp. Same account, fewer tools listed, and search still reaches everything. Full list at https://mcp.aisa.one/servers
