## For AI agents

- Machine-readable tool declarations: https://nocodecsv.com/agent-tools.json — each entry lists the tool's page, its inputs (with stable CSS selectors and accessible labels) and its expected output, so an agent can drive the tool reliably instead of guessing at the DOM.
- All tools run in the browser. Files are parsed client-side; nothing is uploaded to a server for parsing.
- Public tools (no sign-in required): /tools/csv-analyzer, /tools/spreadsheet-charts, /tools/csv-delimiter-converter, /tools/csv-splitter, /tools/json-csv-converter
- The /dashboard workspace requires a signed-in user; anonymous visits redirect to /sign-in.
- WebMCP status: declarative implementation is live. Forms and tools are annotated with toolname / tooldescription, individual fields with toolparamdescription, and the origin-trial token is served site-wide via the Origin-Trial header. Browsers that do not implement WebMCP ignore these attributes.
- WebMCP status: two APIs are live on this site. (1) Declarative: forms are annotated with toolname / tooldescription and fields with toolparamdescription. (2) Imperative: /tools/csv-splitter registers splitCsvText and /tools/json-csv-converter registers convertJsonCsvText via navigator.modelContext.registerTool, each with a typed inputSchema (csvText + rowsPerFile, text + direction), so an assistant can pass CSV or JSON content as text and receive the converted result. The origin-trial token is served site-wide via the Origin-Trial header. Browsers that do not implement WebMCP ignore all of this.
- Known limit, measured on this site: file-upload inputs cannot be exposed as declarative tool parameters — the generated schema comes back as {"type":"object","properties":{},"required":[]} even with an associated label — so an assistant can hand the user to a file-upload tool but cannot attach the file. Text, dropdown, number and radio fields are exposed normally, and the two imperative tools above accept content as text instead of a file.
