AIsa MCP Server認証済み注目

What is AIsa

AIsa is one remote MCP endpoint in front of 950+ data APIs — SEO and AI visibility (DataForSEO, Semrush, Ahrefs), finance (prices, fundamentals, filings, crypto, prediction markets), social (X/Twitter, Instagram, Reddit, Pinterest, YouTube), web search and research (Tavily, Firecrawl, Exa, Perplexity, Oxylabs), sales (Apollo, creator discovery, Similarweb) and agent mail (AgentMail).

One key, one connection, one bill — instead of a developer account, a contract and a rate limit per provider.

Five tools, not 950

Putting 950 operations in tools/list would cost more context than the work. So the endpoint lists five:

Tool	What it does	Price
search	Find an operation from a plain-language task. Returns operation_id, input_schema, price and match reasons.	Free
get_details	Full contract for an operation: schemas, availability, price, known pitfalls.	Free
list_categories	The catalogue at a glance.	Free
use	Run one operation.	Per call
batch_use	Run up to 20 concurrently; one failure never cancels the others.	Per call

search reaches the whole catalogue, so nothing is hidden behind a category. For comparison, Firecrawl's MCP server lists 3 tools and DeepWiki's lists 3 — a short tool list is the norm for servers that route.

Connect

{
  "mcpServers": {
    "aisa": {
      "type": "http",
      "url": "https://mcp.aisa.one/mcp"
    }
  }
}

Nothing has to be created first. An unauthenticated request answers 401 naming its protected-resource metadata (RFC 9728), and the authorization server accepts an unregistered client (RFC 7591), so a client registers itself and signs the user in through a browser. An Authorization: Bearer <AIsa API key> header works instead.

Category endpoints

Same server, a shorter tools/list. Connect one of these to preload just that category; search still reaches everything from any of them.

Endpoint	Tools
https://mcp.aisa.one/seo/mcp	65
https://mcp.aisa.one/finance/mcp	56
https://mcp.aisa.one/social/mcp	61
https://mcp.aisa.one/search/mcp	32
https://mcp.aisa.one/sales/mcp	84
https://mcp.aisa.one/mail/mcp	54
https://mcp.aisa.one/gtm/mcp	48

Any server or module can also be pinned with ?modules=<slug>.

Spending

Discovery is free; use and batch_use are billed per call to the key in the Authorization header. Every paid call accepts max_price_usd, which refuses anything above the cap before any spend — so an agent cannot run up a bill by picking an expensive operation. Call use with operation_id: "account" (free) to see the key, balance and usage for today / 7 days / 30 days.

Cross-checking

The same metric often exists from more than one provider — domain authority from DataForSEO, Semrush and Ahrefs; backlinks from several indexes. search makes that visible in the candidates, so when a decision depends on the number you can cross-check two providers in one batch_use.
