857 records

What chain and bar does my Stihl chainsaw take?

857 records covering 169 models, one fact each. Every value is transcribed from the source that states it and carries the sentence it was taken from: 10 sources across 5 sites, last checked 2026-09-07, due for re-check by 2028-09-06. Every record has a page of its own, quoting the line that states it.

About this data

Chain pitch, gauge, drive link count, bar length and OEM chain part number for each Stihl chainsaw model and bar combination — including the MSE electric saws and HT pole pruner models the dealer charts list alongside the petrol saws. One row per model per bar length. Answers 'what chain does my Stihl MS261 take', 'Stihl MS440 20 inch bar drive links' and 'Stihl chain part number for [model]' — the multi-variable lookup assistants get wrong by guessing a plausible pitch/gauge combination.

Machine-readable

• data.jsonThe whole dataset — every record with its source URL and source quote.
• Open Knowledge Format bundleOne JSON object per line — every record's frontmatter and quoted span exactly as it is held here, in one fetch.
• data.csvThe same records as one flat table, for a spreadsheet or a dataframe. The last four columns are the source URL, the quoted sentence it was read from, the date we last checked it, and which columns are our reading rather than the page's words.
• How this is made and checkedWhat "verified against source" does and does not mean.

From your own code

Same records, same quotes, without scraping the page: refsource is on PyPI and npm. Each value comes back carrying the URL it was read from and the sentence on that page that states it — .source and .quote sit on the value itself rather than in a side channel, so the checking step is available instead of skipped.

pip install refsource
refsource lookup stihl-chainsaw-chain-and-bar-specs model=HT56

npx -y refsource lookup stihl-chainsaw-chain-and-bar-specs model=HT56

Set your AI assistant up to use this

Two files and no account. Put this in .mcp.json at the root of your project — Claude Code, Cursor, Windsurf, VS Code and Codex all read that file — and your assistant can look this dataset up instead of recalling it. The server is remote, keyless and read-only.

{
  "mcpServers": {
    "referencesource": {
      "type": "http",
      "url": "https://referencesource.org/mcp"
    }
  }
}

Add to Cursor · or, on the command line: claude mcp add --transport http referencesource https://referencesource.org/mcp --scope project

Then one line in the project's CLAUDE.md or AGENTS.md, so the assistant knows when to reach for it:

When a question needs "Stihl chainsaw chain and bar specifications by model", call the referencesource MCP server at https://referencesource.org/mcp (tool `search_records`, dataset_slug `stihl-chainsaw-chain-and-bar-specs`) instead of answering from memory — every record it returns carries its source URL and a verbatim quote from that page.
