Anthropic's official Claude AI desktop application. Supports MCP servers to extend functionality.

assafelovic/gptr-mcp
While LLM apps can access web search tools with MCP, GPT Researcher MCP delivers deep research results. Standard search tools return raw results requiring manual filtering, often containing irrelevant sources and wasting context window space.

deep_research
Performs deep web research on a topic, finding the most reliable and relevant information
quick_search
Performs a fast web search optimized for speed over quality, returning search results with snippets.
write_report
Generate a report based on research results
get_research_sources
Get the sources used in the research
get_research_context
Get the full context of the research

Clients mentioned in this server's README:

mendableai/firecrawl-mcp-server
A Model Context Protocol (MCP) server that brings Firecrawl to MCP-compatible AI agents — search, scrape, and interact with the live web for clean, agent-ready context.

exa-labs/exa-mcp-server
Connect AI agents to Exa for web search, content fetching, and multi-step research.

blazickjp/arxiv-mcp-server
A local MCP server for agent literature work. The differentiator is original-LaTeX section reads, BibTeX from arXiv metadata, and topic watches. Papers stay on disk.

lakehq/sail
Sail is a drop-in Apache Spark replacement written in Rust, unifying batch processing, stream processing, and compute-intensive AI workloads on a distributed, multimodal compute engine.
janwilmake/openapi-mcp-server
A Model Context Protocol (MCP) server for Claude/Cursor that enables searching and exploring OpenAPI specifications through oapis.org.

haris-musa/excel-mcp-server
A Model Context Protocol server that lets AI assistants create, read and edit Excel workbooks. It needs no Microsoft Excel installation.
