## Which one, for what

### Contentstack (B)

Good for: Teams already on Contentstack, or starting on its free plan, who want an agent to draft, localise, release and publish structured content with scoped credentials and an audit trail.

Also in its favour:
- Runs on your own machine
- Free to start without a card

Watch for: The MCP server's default group loads 78 tools, including nine deletes, with no readOnlyHint or destructiveHint annotations and no read-only switch

### Webflow (B)

Good for: Teams whose website already runs on Webflow and who want an agent to draft, update and publish CMS items, fix metadata or manage assets.

Ahead on:
- Reliability, 79 against 71
- Schema & documentation, 87 against 77
- Agent ergonomics, 72 against 67
- Security & auth, 74 against 69
- Transparency & trust, 81 against 73

Watch for: The MCP server documents 34 tools (27 data, 3 Designer session, 4 utility), each with several actions, and a granted tool grants all its actions

## Verdicts

**Contentstack.** The Content Management API has a public OpenAPI file, OAuth scopes that separate read, write and publish, read-only management tokens and a stack audit log. A free plan needs no card. The MCP server loads 78 tools by default with no annotations or read-only switch, and the `limit=0` behaviour changed on 11 September 2026 without advance notice.

**Webflow.** The Data API has a public OpenAPI 3.1 spec with 140 operations, scoped OAuth and site tokens, and CMS items that stay drafts until a separate publish call. The MCP server loads 34 multi-action tools and can't create new localised CMS items. The free plan holds 50 CMS items, and the activity log needs the $2,500 Team plan.

## Before you call either

### Contentstack

1. Pick the base URL for the stack's region first. North America on AWS is https://api.contentstack.io, and the other six regions use contentstack.com hosts
2. Send `api_key` and `authorization` headers on every Content Management API call. Ask for a read-only management token when the task only reads
3. Page with `limit` (100 at most), `skip` and `include_count=true`. `limit=0` no longer returns everything
4. Stay under 10 reads and 10 writes a second per organisation, and one bulk request a second. Watch `X-RateLimit-Remaining` and back off on 429
5. Start the MCP server with `--groups cma` only, and add `cma-extended` when the task needs audit logs or version history. Publishing and deleting need no confirmation

### Webflow

1. Send the token as `Authorization: Bearer` to https://api.webflow.com/v2. Ask for `cms:read` and `cms:write` only, plus `sites:write` if the task publishes
2. Create or update items first, then call Publish Items or Publish Site. An item with `isDraft` true and a `lastPublished` date is live with unpublished changes
3. Stay under 60 requests a minute on Starter and Basic and 120 on Premium, read X-RateLimit-Remaining, and wait for Retry-After on 429
4. Page item lists with `limit` (maximum 100) and `offset`, and filter with `filter[<fieldSlug>][<operator>]`, up to 10 terms
5. Upload an asset in two steps (create the asset with a file hash, then POST the bytes to the presigned URL). Write localised content with the item's `cmsLocaleId`
