Connect Cursor
Add the Link in Seconds MCP server to Cursor so the agent can publish what it builds as a live link.
Cursor reads MCP servers from an mcp.json file. Add Link in Seconds and the agent can publish what it builds, such as a prototype page or a generated report, and hand you a shareable link.
Create an API key
Open Dashboard → API keys, create a key named “Cursor” and copy it.
Add the server to mcp.json
Use
~/.cursor/mcp.jsonto have it in every project, or.cursor/mcp.jsonin one project. Cursor can read the key from an environment variable, which keeps it out of the file:~/.cursor/mcp.json{ "mcpServers": { "linkinseconds": { "url": "https://linkinseconds.com/api/mcp", "headers": { "Authorization": "Bearer ${env:LIS_API_KEY}" } } } }Set
LIS_API_KEYin your shell profile and restart Cursor, or paste the key in place of${env:LIS_API_KEY}if the file never leaves your machine.Check it in settings
Open Cursor Settings, then the MCP section.
