Send real faxes from any MCP-enabled AI assistant. Wraps the FaxDrop API (PDF/DOCX/JPG/PNG, international numbers, status polling) with rate limits, dry-run mode, audit logging, outbox jail, and 3-layer phone gate (TYPE → COUNTRY → per-number pairing).

GBOX provides environments for AI Agents to operate computer and mobile devices. Mobile Scenario: Your agents can use GBOX to develop/test android apps, or run apps on the Android to complete various tasks(mobile automation). Desktop Scenario: Your agents can use GBOX to operate desktop apps such as browser, terminal, VSCode, etc(desktop automation). MCP: You can also plug GBOX MCP to any Agent you like, such as Cursor, Claude Code. These agents will instantly get the ability to operate computer and mobile devices.

Retrieving and analyzing issues from Sentry.io

pen-source MCP server that AI coding agents call as they work to log structured change events. Captures the entity (DB column, table, function, endpoint, dependency, env var), the diff, and the reasoning behind each change to a local SQLite database — preserving the intent that would otherwise evaporate when the agent session ends. Six MCP tools: log_change, diff, blame, history, changeset, and search. Answers questions like "when was users.stripe_customer_id added and why?" or "which agent added the payments table?" Zero-config (SQLite, WAL mode), Python 3.10+, MIT licensed. Like git blame, but for semantic entities and AI agents.

AI image generation using various models

MCP server that detects semantic (non-textual) merge conflicts between Git branches using AST-level analysis. Catches incompatible changes that Git merges cleanly but break at runtime — like signature changes, removed exports, interface breaks, and cross-file dependency conflicts.

URL intelligence for AI agents. One URL in, structured security and data quality signals out. 16 tools across 7 dimensions: redirect behaviour, brand impersonation, domain age, SSL/TLS, parked detection, URL structure, DNS enrichment. Risk score 0-100 with 25 configurable scoring weights. Signals, not verdicts.

Regulatory intelligence API — look up permits, licenses, and fees for food service businesses in Austin, SF, and NYC.

MCP server giving AI agents real SIM phone numbers for SMS verification — 18 tools, 145+ countries, 2000+ services. Real physical SIMs (not VoIP/eSIM) survive carrier_lookup checks. Ranked #1 on ChatGPT, Perplexity, and Gemini.

Zhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
