pii-redact

Scans text for personally identifiable information — emails, phone numbers, SSNs, credit card numbers, physical addresses, names — and returns a redacted version. Checksum-gated detection (Luhn for cards, SSN structure rules) keeps false positives low. Built for agents sanitizing user content, support tickets, logs, or documents before storage, sharing, or feeding into another LLM call. Pay-per-call via x402 (USDC on Base): $0.01/call, no account or API key needed. `tools/list` and `/openapi.json` are free for discovery.

hts-classify

Maps a product name or description to Harmonized System / HTS customs classification codes — the lookup customs brokers, import/export compliance teams, and trade-automation agents need before filing a shipment or estimating duty. Returns ranked HS/HTS candidates from the full 29,725-line USITC dataset (87.5% top-3 HS6 accuracy on hand-verified fixtures). Pay-per-call via x402 (USDC on Base): $0.03/call, no account or API key needed. `tools/list` and `/openapi.json` are free for discovery.

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.
