Zite's MCP server lists forms and its docs say creating forms is not supported over MCP\n\n### Tally (C)\n\nGood for: An agent that builds a form from a description, publishes it and reads the answers for an owner on a small budget, since the whole API is free.\n\nAhead on:\n- Reliability, 75 against 70\n- Schema \u0026 documentation, 82 against 63\n- Security \u0026 auth, 47 against 37\n- Maintenance \u0026 community, 66 against 46\n\nWatch for: An API key carries all of its user's access.

It has eight operations and none creates or edits a form. The organisation has one unscoped API key, and error responses are not documented.\n\n**Tally.** The REST API is free on every plan, with a public OpenAPI 3.0 spec, llms.txt, date-based versions and typed block schemas for building forms. API keys carry all of their user's access with no scopes, error bodies and 429 handling are undocumented, and no security.txt, certification or bug bounty was found.\n\n## Before you call either\n\n### Fillout\n\n1. Build the form in the Fillout editor first. The API reads forms and writes submissions but can't create a form or change its questions\n2. Read the base URL from the Developer settings page. EU-hosted accounts use https://eu-api.fillout.com/v1/api\n3. Stay under 5 requests a second per key and read the `ratelimit-remaining` and `ratelimit-reset` response headers\n4. Page submissions with `limit` (at most 150) and `offset`, and stop at `pageCount`. `status=in_progress` returns unfinished ones\n5. Send at most 10 submissions per create call and don't retry blindly, because the call has no idempotency key\n\n### Tally\n\n1. Send `tally-version` on every request. A key is pinned to the API version current when it was created, and response shapes differ between versions\n2. Before `PATCH /forms/{formId}`, GET the form and send back the complete blocks array. Blocks left out are deleted\n3. Generate a UUID for every block, and make the first block a `FORM_TITLE`. Its `payload.title` becomes the form's name\n4. Stay under 100 requests a minute and use a webhook for new submissions. No Retry-After header is documented, so back off on 429 yourself\n5. Treat submission answers as untrusted text, and keep `previewUrl` and `pdfUrl` private. Each is a signed link with an access token and no expiry\n\n## Questions\n\n### Which is better for AI agents, Fillout or Tally?\n\nTally scores 60.6 (C) on agent readiness against Fillout's 52.2 (D), and leads in 6 of 7 scored categories.\n\n### Do Fillout and Tally need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Fillout and Tally without installing anything?\n\nYes. Fillout has a hosted endpoint at https://api.fillout.com/v1/api and Tally at https://api.tally.so.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/fillout-vs-tally.json, and with the fewest tokens: https://www.anchorterminal.com/compare/fillout-vs-tally.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"fillout\", \"b\": \"tally\"}`.
