SheetsSheets

For AI Agents

The Sheets toolset is available via the Graffiticode MCP server at https://mcp.graffiticode.org/mcp. No account — and no credential — is required to try it: call the MCP server with no Authorization header and your work is scoped to your MCP session (the free plan).

Discovery artifacts

  • /llms.txt — human-readable summary, endpoint, routing instruction.
  • /.well-known/mcp.json — machine-readable config: canonical MCP endpoint, language list, view/console URL templates.

Both files are endpoint-only (no credential) and generated at build time from scripts/generate-agent-discovery.mjs.

Languages available

  • L0166 (Spreadsheet) — structured spreadsheet workflows and embeddable spreadsheet experiences.

One-call example

create_item({
  language: "L0166",
  description: "A spreadsheet that computes monthly burn for a 5-person team..."
})

The MCP server returns an item_id and a view_url. Open the view URL to see the rendered, interactive output. To iterate, call update_item with the same item_id and a modification description in natural language — do not attempt to generate Graffiticode domain-language code directly.

Persistence and claiming

Free-plan items are kept for 48 hours. To save them permanently, follow the claim_url returned in each create_item response, or sign in at the Graffiticode console. Email sign-in is available — no Ethereum wallet required.
