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.\n\n**Kontent.ai.** Management API keys take per-area permissions, environment limits and an expiry from one minute to two years, and changes made with a key are named in the audit log. Rate limits and Retry-After are documented. No price is published, and no OpenAPI file was found. Access starts with a 30-day trial that a person opens in a browser.\n\n## Before you call either\n\n### Contentstack\n\n1. 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\n2. Send `api_key` and `authorization` headers on every Content Management API call. Ask for a read-only management token when the task only reads\n3. Page with `limit` (100 at most), `skip` and `include_count=true`. `limit=0` no longer returns everything\n4. 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\n5. 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\n\n### Kontent.ai\n\n1. Send `Authorization: Bearer \u003ckey\u003e` to `https://manage.kontent.ai/v2/projects/{environment_id}/...`. The Management API must be switched on under Environment settings, General, Enabled APIs first\n2. Ask for a Management API key with only the permissions the task needs. Read content alone gives a read-only key, and keys expire after six months by default\n3. Stay under 10 requests a second and 400 a minute per environment, send requests one at a time, and wait the seconds in Retry-After on a 429\n4. Page lists by passing the `continuation_token` from the response back in the `x-continuation` header\n5. Create items with an `external_id` and write with the upsert PUT at `/items/external-id/{id}` so a retry after a lost response does not create a duplicate\n6. With the MCP server, call `get-patch-guide` before any patch tool, and use a client that prompts on destructiveHint\n\n## Questions\n\n### Which is better for AI agents, Contentstack or Kontent.ai?\n\nKontent.ai scores 70.5 (BB) on agent readiness against Contentstack's 64 (B), and leads in 5 of 7 scored categories. Contentstack leads on payments \u0026 pricing.\n\n### Do Contentstack and Kontent.ai need an API key?\n\nContentstack takes an API key or an OAuth sign-in. Kontent.ai needs an API key.\n\n### Can an agent call Contentstack and Kontent.ai without installing anything?\n\nYes. Contentstack has a hosted endpoint at https://api.contentstack.io and Kontent.ai at https://manage.kontent.ai/v2.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/contentstack-vs-kontent-ai.json, and with the fewest tokens: https://www.anchorterminal.com/compare/contentstack-vs-kontent-ai.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"contentstack\", \"b\": \"kontent-ai\"}`.
