"Server compatibility with ChatGPT or DeepSeek" matching MCP servers:

MCP server that provides OpenRouter model pricing data, enabling price lookups, trending/cheapest lists, and model searches without an API key.

A general MCP server providing web search capabilities using DeepSeek's native online search API.

An MCP server that provides web search powered by DeepSeek's native search API, returning AI-generated answers with source links. Integrates with MCP-compatible clients like Claude Code and Cursor.

Enables real-time web search via DeepSeek's server-side tool without requiring additional search API keys.

A DeepSeek-powered MCP server that provides high-accuracy web search using the native DeepSeek V4-Flash search API, offering standard and deep research tools that return cited answers and cross-verified reports.

Provides access to OpenAI's ChatGPT API with web search capabilities for Claude and other MCP clients. Supports various GPT models with configurable parameters like reasoning effort, temperature, and streaming mode.

An experimental guarded MCP bridge for Codex/open-ultrawork workflows, enabling submission of bounded research jobs to ChatGPT Pro asynchronously with source verification and safety guards.

Enables ChatGPT to perform read-only lookups on public data sources including WHOIS domain information, UK Companies House records, and SEC EDGAR filings through a self-hosted MCP server with an ngrok tunnel.

Provides a read-only MCP server to access ChatGPT conversation history via a local browser process. Allows AI clients to list, get, and search conversations from the authenticated user's ChatGPT account.
