An MCP server that converts raw text prompts into structured JSON prompts using heuristic keyword extraction — no API keys required.

Provides deterministic JSON repair and JSON Schema validation for malformed AI agent outputs, safely fixing unambiguous errors without an LLM and refusing ambiguous cases.

A local MCP/CLI tool that uses a Chrome profile with an active ChatGPT web session to submit image generation prompts and return saved images as MCP content.

Enables MCP clients and a terminal CLI to run web searches through a user's own SearXNG instance, saving every query as a reusable session and optionally generating AI-synthesized answers.

Enables AI agents to generate text, images, and videos via Grok's web UI using MCP tools (grok_chat, grok_generate_image, grok_generate_video) without an API key.

Json AI - MCP server providing AI-powered tools and automation by MEOK AI Labs

Enables AI agents to delegate simple text subtasks such as summarising, translating, classifying, extracting, and reformatting to free web AIs through the user's own Edge/Chrome browser, returning only plain-text answers to save the main model's context and tokens.

Provides web and image search using the Doubao (Volcengine) API with configurable parameters.

Enables Codex to interact with Gemini Web through browser automation, allowing it to ask scoped questions and analyze public URLs or YouTube videos without a Gemini API key.

Enables agents and MCP clients to deterministically extract and repair JSON/schema issues such as truncated braces, markdown wrappers, and invalid types without LLM round-trips.
