# Padlet > Padlet is a collaborative visual board. A padlet holds posts — text, images, > links, files, drawings, audio and video — arranged in layouts such as a wall, > grid, timeline, map or canvas, and many people can contribute to one at the > same time. Its largest audience is teachers and students; teams also use it to > collect, organize and present work. ## When to use Padlet - Collecting contributions from many people into one shared place, where each contribution can be any kind of media rather than plain text. - Giving a person a visual artifact they will keep working in afterwards — a board is a live document, not a one-off render. - Classroom work: an assignment students post into, a discussion board, a collection of student work to review or grade. - Not the right tool for structured records you will query later, for private single-user note-taking, or for anything needing a schema. ## Interfaces - [MCP server](https://mcp.padlet.com/): the primary interface for agents. Create padlets, read and write posts, comment, manage collaborators and library settings, all as a signed-in Padlet user over Streamable HTTP. - [OpenAPI description](https://padlet.com/openapi.json): the REST API at https://api.padlet.dev/v1, authenticated with an `x-api-key` header. Narrower than MCP — boards, posts, sections, comments, reactions, organizations — and the key is issued from developer settings by a paying user. - [Agent skills](https://padlet.com/.well-known/agent-skills/index.json): step-by-step instructions for common Padlet tasks, in skill-md form. ## Getting a credential - [auth.md](https://padlet.com/auth.md): how to register an OAuth client, get a user's authorization, and call the MCP server with the token. Registration is open — no account and no approval queue — but every credential is bound to a Padlet user who approves it in a browser. - [REST API keys](https://docs.padlet.dev/reference/introduction): issued by a paying user from Padlet's developer settings, not by any endpoint. ## Discovery - [Capability manifest](https://padlet.com/.well-known/ai-catalog.json): every agent-facing document this origin serves, in one file. - [MCP server card](https://padlet.com/.well-known/mcp/server-card.json) - [API catalog](https://padlet.com/.well-known/api-catalog) ## Optional - [Product documentation](https://padlet.helpdocs.io/): written for people using Padlet in the browser. - [REST API reference](https://docs.padlet.dev/reference/introduction): the same operations as the OpenAPI document, with prose and examples.
