What it does

The Linkup server gives an agent access to the internet through the Linkup service API. The linkup-search tool searches by a natural-language query in two depth modes: standard for questions with a direct answer and deep for comparisons across several sources. Results are narrowed with includeDomains and excludeDomains lists, a date range with fromDate and toDate, and a maxResults count. Images can be requested. The linkup-fetch tool pulls page content, optionally with JavaScript rendering, an image list and raw HTML. For questions one search cannot answer there is the linkup-research and linkup-get-research pair: the first starts an autonomous investigation and returns an id, and the second polls the task until completed or failed. The modes answer, investigate and research set the kind of result, and reasoningDepth from S to XL sets the time spent. The server is hosted at https://mcp.linkup.so/mcp, and a local run through npx is available. A ready MCPB package is published for Claude Desktop.

Who it is for. Developers and researchers who need fresh news, prices and facts in the answers of Claude Code, Cursor or Codex instead of the model's built-in knowledge.

Limitations

A Linkup API key is required, and a free account is created in the dashboard. If the client can send headers, pass the key in Authorization: Bearer and keep the apiKey URL parameter for clients that cannot. A linkup-research task usually takes several minutes, and polling more often than once a second is rate-limited. Developing the server itself needs Node.js 24 or newer. Availability of Linkup from Russia was not checked.

How to disable. Remove the server from the client: claude mcp remove linkup, the linkup entry in mcp.json or the table in Codex config.toml. Revoke the key at app.linkup.so.

README in short

The README gives connection methods for Cursor, VS Code and Codex, an MCPB package for Claude Desktop and a local stdio run. It then describes the four tools with their parameters and example queries, and ends with development commands and debugging through MCP Inspector.
