Password Strength Checker — Entropy & Crack Time

Password strength evaluation API for AI agents. Score 0-100 with entropy bits, estimated crack time (brute force and dictionary), pattern detection, and actionable improvement tips. Tools: security_check_password. Use this for password policy enforcement, user registration validation, or security audits. Returns machine-readable strength data for automated decisions. Returns: {score, entropy, crackTime, tips[]}. No API key required — x402 micropayment $0.001/call on Base L2.

Fact Checker — Verify Claims with Web Evidence

AI-powered fact-checking API for AI agents. Verify any factual claim with web evidence: searches multiple sources, assesses credibility, provides supporting/contradicting URLs, and returns confidence level (confirmed/likely/unverified/false). Tools: research_check_fact. Use this before repeating claims, for content moderation, or building trustworthy AI systems. Essential for reducing hallucinations. IMPORTANT: For web search without fact assessment, use web_search_query. Returns: {verdict, confidence, sources[], evidence[]}. No API key required — x402 micropayment $0.005/call on Base L2.

Text Classifier — Topic Categories & Readability

Text classification API for AI agents. Classify text into topic categories with confidence scores, readability metrics (Flesch-Kincaid), and content type detection (article, review, email, code, etc.). Tools: text_classify_content. Use this for content routing, auto-tagging, spam detection, or organizing unstructured text. IMPORTANT: For sentiment analysis, use text_analyze_sentiment instead. Returns: {categories[], readability, contentType, confidence}. No API key required — x402 micropayment $0.005/call on Base L2.

Image Resizer — Resize, Convert PNG/JPEG/WebP

Image resize and format conversion API for AI agents. Resize images from URL: custom width/height, format conversion (PNG, JPEG, WebP), aspect ratio preservation, and quality control. Tools: media_resize_image. Use this for thumbnail generation, image optimization, or preparing assets for different platforms. Returns base64-encoded processed image. Returns: base64-encoded resized image. No API key required — x402 micropayment $0.003/call on Base L2.

Currency Converter — Fiat & Crypto Cross-Rates

Currency conversion API for AI agents. Convert between fiat currencies (ECB rates) and crypto (CoinGecko rates). Instant cross-rate lookup for USD, EUR, GBP, JPY, BTC, ETH, and 100+ currencies. Tools: finance_convert_currency. Use this for price normalization, international pricing, or cross-currency calculations. Supports both fiat-to-fiat and fiat-to-crypto conversions. Returns: {result, rate, from, to, timestamp}. No API key required — x402 micropayment $0.001/call on Base L2.

Email Deliverability Audit — SPF/DKIM/DMARC Check

Email deliverability audit API for AI agents. Analyze any domain's email authentication: SPF record validation, DKIM selector check, DMARC policy analysis, MX record health, and composite deliverability score 0-100 with prioritized fix recommendations. Tools: email_audit_deliverability. Use this when auditing email infrastructure, diagnosing delivery issues, or checking domain reputation before sending campaigns. IMPORTANT: This checks the DOMAIN's setup — for individual email validation, use email_verify_address instead. Returns: {score, spf, dkim, dmarc, mx, recommendations[]}. No API key required — x402 micropayment $0.005/call on Base L2.

NodeAPI

Machine-native GIS processing API for AI agents and developers. Convert, reproject, validate, repair, buffer, clip, dissolve, and tile vector geodata across 25 endpoints. Pay-per-use USDC on Solana Mainnet ($0.01/op). No accounts, no API keys. Remote MCP SSE.

astllm-mcp

An MCP server for efficient code indexing and symbol retrieval using tree-sitter AST parsing to fetch specific functions or classes without loading entire files. It significantly reduces AI token costs by providing O(1) byte-offset access to code components across multiple programming languages.

Openterms-mcp

Cryptographic proof of consent for AI agents. Sign before you act. Policy engine enforces spending caps, action whitelists, and escalation rules. Independently verifiable by anyone.

KreatorFlow

Generate Seedance AI video and Seedream images from Claude, ChatGPT, Cursor or any MCP client. KreatorFlow's MCP server puts an AI media studio in the assistants you already use. Ask for a clip in chat and your assistant generates Seedance video or Seedream images, edits images and video, swaps faces, runs Kitsune motion transfer, turns text into speech, makes music and sound effects, clones voices and transcribes audio. Powered by ByteDance's Seedance and Seedream models via BytePlus. **How it works** - Add `https://kreatorflow.ai/api/mcp` as a remote MCP server (Streamable HTTP). - Sign in with your own KreatorFlow account through OAuth 2.1 with PKCE. No API key to paste. - Each generation uses your own paid plan's credits at studio prices. Failed jobs are refunded automatically, and results are saved to your History. A paid KreatorFlow plan is required. Setup guides for Claude, Claude Code, ChatGPT, Cursor, VS Code and Windsurf: https://kreatorflow.ai/mcp Developers can use the API-key server at `https://kreatorflow.ai/v1/mcp` instead, billed in prepaid API tokens.

Aegis-ZK

On-chain trust verification for AI agent tools. Agents query skill attestations, audit levels, and risk scores before running third-party MCP servers, so you know what's safe before you execute.

Satoshidata Wallet Intelligence

Bitcoin wallet intelligence for AI agents: labels, risk signals, transactions, fees, and mempool.
