Google ADK integration for Strale — 250+ business capabilities as agent tools

google-adk-strale

Google Agent Development Kit (ADK) integration for Strale — 250+ independently tested and scored business data capabilities for AI agents.

Strale provides IBAN validation, VAT validation, company data across 27 countries, sanctions screening, compliance checks (KYB, AML, GDPR), invoice extraction, SSL certificate checks, and more. Every capability is quality-scored with the Strale Quality Score (SQS).

Installation

pip install google-adk-strale

Approach 1: MCP Native (Recommended)

Google ADK supports MCP natively. Point it at Strale's MCP endpoint and ADK discovers all 250+ tools automatically — no wrapper package needed:

from google.adk import Agent
from google.adk.tools.mcp_tool import MCPToolset, StreamableHTTPConnectionParams

strale_tools = MCPToolset(
    connection_params=StreamableHTTPConnectionParams(
        url="https://api.strale.io/mcp",
        headers={"Authorization": "Bearer sk_live_..."},
    )
)

agent = Agent(
    model="gemini-2.0-flash",
    name="compliance_agent",
    instruction="You verify business data using Strale tools.",
    tools=[strale_tools],
)

This gives your agent access to all Strale tools (strale_search, strale_execute, strale_balance, etc.) with zero configuration.

Approach 2: REST Client (Custom Tool Logic)

For fine-grained control, use StraleClient in ADK tool functions:

from google.adk import Agent
from google_adk_strale import StraleClient

strale = StraleClient(api_key="sk_live_...")

def validate_iban(iban: str) -> dict:
    """Validate an IBAN number. Returns validity, country, bank BIC, bank name."""
    return strale.run("iban-validate", {"iban": iban})

def check_sanctions(name: str, country: str = "") -> dict:
    """Screen a name against global sanctions lists (OFAC, EU, UN)."""
    inputs = {"name": name}
    if country:
        inputs["country"] = country
    return strale.run("sanctions-check", inputs)

def lookup_company(org_number: str) -> dict:
    """Look up Swedish company data by organization number."""
    return strale.run("swedish-company-data", {"org_number": org_number})

agent = Agent(
    model="gemini-2.0-flash",
    name="compliance_agent",
    instruction="You verify business data using Strale tools.",
    tools=[validate_iban, check_sanctions, lookup_company],
)

When to Use Which Approach

	MCP Native	REST Client
Setup	3 lines	Write each tool function
Tool count	All 250+ automatically	You choose which to expose
Auth	Bearer token via MCP	Bearer token via REST
Custom logic	No (tools are standard)	Yes (wrap, transform, combine)
Offline/testing	Needs MCP connection	Can mock StraleClient

Use MCP when you want all capabilities with zero setup. Use REST when you need custom input/output transformation or want to limit which tools are available.

Discover Capabilities

from google_adk_strale import StraleClient

strale = StraleClient(api_key="sk_live_...")

# List all capabilities
caps = strale.list_capabilities()
print(f"{len(caps)} capabilities available")

# Filter by category
compliance_caps = strale.list_capabilities(category="compliance")
for cap in compliance_caps:
    print(f"  {cap['slug']} — €{cap['price_cents']/100:.2f}")

Capability Categories

Category	Examples
Company Data	swedish-company-data, german-company-data, uk-company-data (27 countries)
Compliance	sanctions-check, pep-check, adverse-media-check, vat-validate
Validation	iban-validate, vat-format-validate, lei-lookup, swift-validate

Full list: strale.dev/capabilities

Free Tier

5 capabilities work without an API key or signup: email-validate, dns-lookup, json-repair, url-to-markdown, iban-validate.

Trust & Quality

Every Strale capability has a quality score (SQS) combining:

• Quality Profile: correctness, schema compliance, error handling, edge cases
• Reliability Profile: availability, success rate, upstream health, latency

Scores and methodology: strale.dev/trust

Using Strale in agent system prompts

Add this to your Google ADK agent's instructions for automatic capability routing:

When you need to verify a business, validate an IBAN or VAT number, screen
against sanctions/PEP lists, extract data from a URL or document, or check
compliance — use your Strale tools. Call strale_search to find the right
capability, then call it by name. Returns structured JSON with quality scores.
250+ capabilities across 27 countries. Free tier: email-validate, dns-lookup,
json-repair, url-to-markdown, iban-validate (no API key needed).
