Strale MCP server

Strale

Trust and quality infrastructure for AI agents.

What Strale is

Strale is a capability marketplace for AI agents. Agents call strale.do() at runtime to reach verified capabilities — company registry lookups, compliance checks, financial validation, Web3 security, and more — plus bundled solutions for multi-step workflows like a full KYB check or company due diligence, instead of the agent's own code hardcoding integrations and managing credentials for every data source it might need.

Every capability is watched: free-tier capabilities are tested against real upstreams on a schedule, paid capabilities are watched through production observability and an enforced quality floor, and every call returns a structured, auditable result with source provenance. The current catalog, free-tier list, and country coverage are live values, not numbers printed here — see How to use it below for where to read them.

How to use it

MCP server (recommended: no install)

{
  "mcpServers": {
    "strale": {
      "type": "streamableHttp",
      "url": "https://api.strale.io/mcp",
      "headers": {
        "Authorization": "Bearer sk_live_your_key_here"
      }
    }
  }
}

Works with Claude Desktop, Claude Code, Cursor, and any MCP client supporting Streamable HTTP. For local stdio instead, or the full tool surface, see packages/mcp-server/README.md.

TypeScript SDK

npm install straleio

import Strale from "straleio";

const strale = new Strale({ apiKey: process.env.STRALE_API_KEY });
const result = await strale.do("eu-vat-validate", { vat_number: "SE556000000001" });

Python SDK

pip install straleio

from straleio import Strale

strale = Strale(api_key="your_api_key")
result = strale.do("eu-vat-validate", {"vat_number": "SE556000000001"})

Get started without an API key

A subset of capabilities (email/IBAN/crypto-address validation, DNS lookup, JSON repair, URL-to-markdown, and more) work with no signup, no API key, and no wallet — only an IP-based daily rate limit. Read the current list from GET /v1/platform/facts (freetierslugs), not from a number in this file. Get a key and trial credits at strale.dev when you need the rest of the catalog.

Framework integrations
