mcp-greasyfork-scripts

an mcp server that searches greasy fork and fetches userscript source code. gives your coding agent access to thousands of userscripts — tampermonkey, greasemonkey, violentmonkey scripts — as rich context.

what it does

two tools:

search-scripts

searches greasy fork by keyword. accepts up to 10 search queries in parallel, fetches all result pages concurrently (semaphore of 10), deduplicates by script id. returns results as a TSV table with id, name, description, install counts, ratings, dates, and code urls. maximum 1000 results displayed per call.

get-script-details

takes greasy fork script urls and fetches complete metadata plus the full javascript source code. returns a formatted markdown report with metadata headers and fenced code blocks.

how it works

• scrapes greasy fork search result pages (HTML parsing via regex on data-script-* attributes)
• fetches all pagination pages in parallel with concurrency control
• deduplicates scripts across multiple search queries
• fetches script metadata via greasy fork json api and source code from code urls
• no api keys or tokens required — greasy fork is fully public

install

add to your mcp config:

{
  "mcpServers": {
    "greasyfork": {
      "command": "npx",
      "args": ["-y", "mcp-greasyfork-scripts"]
    }
  }
}
