The traditional admin-panel CMS isn't enough; you need programmatic read and write access that an agent can use as a tool.\n\nHeadless CMS platforms are the natural fit here. They separate the content layer from the presentation layer and expose everything through REST or GraphQL APIs. This makes it straightforward to wrap content operations as agent tools.\n\n**What to consider:**\n\n- **API-first design** — headless CMS platforms (Contentful, Sanity, Strapi, Payload) are built API-first. WordPress can work headless via its REST API, but it wasn't designed for it and the API reflects that.\n- **Content modeling** — how flexible is the schema? Sanity and Payload define models in code, which makes version control natural. Contentful and Strapi use UI-based modeling with migration support. WordPress has a fixed post/page model extended through custom fields.\n- **Self-hosting** — if data residency matters, Strapi, Payload, and WordPress can be fully self-hosted. Contentful and Sanity are cloud-only.\n- **Real-time capabilities** — Sanity supports real-time subscriptions, which enables agents that react to content changes. Most others require polling or webhooks.\n- **Cost** — WordPress and Strapi are free to self-host. Payload has a generous free cloud tier. Sanity's free tier includes 500k API requests. Contentful's free-to-paid jump is the steepest.\n\nFor agent workflows, the most important factor is how cleanly the CMS API maps to agent tool definitions. A well-structured API with typed schemas makes it easier for agents to create, update, and query content without hallucinating field names or structures."}
