Checks that the Strale API is reachable and the MCP server is running. Call this before a series of capability executions to verify connectivity, or when troubleshooting connection issues. Returns server status, version, tool count, capability count, solution count, and a timestamp. No API key required.

Lists the free capabilities available without an API key and explains how to get started. Call this on first connection to see what you can do immediately. Returns 5 free capability slugs (email-validate, dns-lookup, json-repair, url-to-markdown, iban-validate) with descriptions, example inputs, and instructions for accessing the full registry of 271 paid capabilities. No API key required.

Executes a Strale capability by slug and returns the result. Use this when you need to perform any verification, validation, lookup, or data extraction from the capability registry. Call strale_search first to find the right slug and required input fields. Returns a result object with the capability output, latency, price charged, and data provenance. Several capabilities are free without an API key (10/day limit) — strale_search reports which. Paid capabilities debit from the wallet — check strale_balance first for high-value calls.

Searches the Strale capability registry by keyword, category, or natural language query. Use this when you need to find the right capability for a task but don't know the exact slug. Returns matching capabilities and solutions ranked by relevance, each with slug, name, description, category, and price in EUR cents. The registry spans company data, compliance, finance, web intelligence, and developer tools. No API key required to search.

Returns the current Strale wallet balance. Call this before executing paid capabilities to verify sufficient funds, or after a series of calls to reconcile spend. Returns balance in EUR cents (integer) and formatted EUR string. Requires an API key — returns an auth instruction if none is configured.

Returns Strale's trust methodology as a short reference document — covers test cadence, audit-trail integrity, and provenance. No API key required.

Returns the trust profile for a capability or solution. Call this before relying on a capability for high-stakes decisions, or when a user asks how reliable a specific check is. Returns lifecycle state, last-tested timestamp, recent test history, known limitations, data source and provenance, and cost envelope. Strale deliberately exposes no single numeric quality score — judge from the test history and limitations. No API key required.

Retrieve a past execution record by transaction ID. Returns inputs, outputs, latency, price, data provenance, success/failure status, and failure categorization. Use this to inspect what a previous strale_execute call returned, debug failures, or provide an audit trail. Free-tier transactions are accessible by ID without an API key.

Returns a decision-ready answer about an on-chain counterparty (wallet, smart contract, token, DeFi protocol, or bridge) in a single call. Surfaces verdict (proceed/review/block/insufficient_evidence), reason_codes (machine-parsable UPPERCASE_SNAKE_CASE), critical_flags, suggested_action, evidence map (sanctions, mixer-graded, scam-cluster, wallet-history, token-safety, contract-verification, protocol-risk, EAS attestations, ERC-8004 reputation, more), and a sidecar audit_url. Two modes: 'outbound' (agent vetting recipient pre-payment, full evaluator set, 8s budget) or 'reverse-call' (service publisher gating an inbound x402 buyer in real-time, critical evaluators only, sub-second SLA). Use before any agent transacts on-chain — sending value, swapping, staking, minting, bridging, or interacting with a contract.

Overview

What is Strale — Trust And Quality Infrastructure For Ai Agents?

Strale is a capability marketplace for AI agents. Agents call strale.do() at runtime to access 225+ verified capabilities — company lookups, compliance checks, financial data, web extraction, and more — without hardcoding integrations or managing credentials. Every capability is continuously tested and assigned a Strale Quality Score (SQS) from 0 to 100, providing reliable, scored tools and observability.

How to use Strale — Trust And Quality Infrastructure For Ai Agents?

Add the MCP server to your Claude Desktop or Cursor config using npx -y strale-mcp and set the STRALE_API_KEY environment variable. Five capabilities are available without an API key. Alternatively, use the TypeScript SDK (npm install straleio), Python SDK (pip install straleio), or integrations like LangChain, CrewAI, and Semantic Kernel.
