Setting up with Highlight

This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:

  1. Download and install Highlight from highlightai.com/download
  2. Navigate to the plugins tab and select "Add Custom Plugin"
  3. Configure the plugin with the settings below
    Plugin Name Strale — Trust And Quality Infrastructure For Ai Agents
    Command (node, npx, python, etc.)

    Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.

  4. Enable "Start Automatically" if you want the plugin to start when Highlight launches

From the repository

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.

Claude Desktop / Cursor

Paste into your MCP client config file to install this server.

Trust and quality infrastructure for AI agents.

Strale is a capability marketplace for AI agents. Agents callstrale.do()at runtime to access verified capabilities — company registry lookups, compliance checks, financial validation, Web3 security, and more — plus bundled solutions for multi-step workflows like full KYB checks or company due diligence. No hardcoded integrations or credential management.

Every capability is continuously tested against real upstreams, and every call returns an audit record with cryptographic chain hashing. You get observability into what your agent is actually doing.

Recommended: Streamable HTTP (remote, no install)

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

No installation required. Works with Claude Desktop, Claude Code, Cursor, and any MCP client supporting Streamable HTTP.

{ "mcpServers": { "strale": { "command": "npx", "args": ["-y", "strale-mcp"], "env": { "STRALE_API_KEY": "your_api_key" } } } }

Five capabilities (email-validate,dns-lookup,json-repair,url-to-markdown,iban-validate) are available without an API key. Get a key and €2 free credits atstrale.dev.

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" }); console.log(result);
from straleio import Strale strale = Strale(api_key="your_api_key") result = strale.do("eu-vat-validate", {"vat_number": "SE556000000001"})

17 Web3 capabilities and 9 bundled solutions for on-chain agents: wallet risk scoring (GoPlus), token honeypot detection, ENS resolution, DeFi protocol TVL and fees (DeFi Llama), gas oracle, EU MiCA VASP verification (ESMA register), and market sentiment. All available via the x402 payment protocol — pay per call with USDC on Base mainnet, no signup required.

Capabilities are continuously tested against their real upstreams. Each one carries a suite of automated tests — known-answer, schema, negative, edge-case, and dependency-health — plus piggyback checks fed by real production traffic. Results drive a lifecycle state (draftvalidatingprobationactivedegradedsuspended) and an enforced quality floor: a capability that falls below the floor on real traffic is quarantined automatically, and recovers the same way.

Strale deliberately publishesno single numeric quality score. An earlier 0-100 composite (SQS) was retired in May 2026 — it compressed unrelated failure modes into one number that looked more precise than it was. What is exposed instead is the raw evidence: lifecycle state, last-tested timestamp, recent test history, known limitations, and the data source behind each capability.

Teach your AI coding agent how to use Strale:

- Agent Skills— SKILL.md files for Claude Code, Cursor, Copilot, and Codex. Copyskills/strale/into your project's.claude/skills/,.github/skills/, or.cursor/skills/directory.

- Verify a company with Strale(Python)
-
Validate IBANs — free, no API key(Python)
-
Build an agent with Strale(TypeScript)
-
Connect Strale to Claude(setup guide)

Strale is the trust layer for AI agents.

Drop these files into your project to give your coding agent security guidance for trust-sensitive data (IBANs, company registries, sanctions, PII):

- Cursor:Copydocs/ide-rules/strale-compliance.mdcto.cursor/rules/
- Windsurf:Copy
docs/ide-rules/strale-compliance.windsurfrulesto your project root, or into.windsurf/rules/as a.mdfile
- Claude Code:Copy the snippet from
docs/claude-md-snippet.mdinto your project'sCLAUDE.md

These rules prevent the most common vibe-coding vulnerabilities: client-side IBAN validation, hardcoded API keys, missing provenance metadata, and direct registry scraping. Free-tier endpoints are referenced as safe defaults that require no API key.
