Files and images with agents
Use secure image and file workflows across Claude Code and other MCP clients.
Last updated
Agents can work with document images and collection files without embedding private storage credentials in the conversation.
Document images
An agent can attach an existing Quire image, import from a public HTTPS URL, or send supported base64 image data. PNG, JPEG, and WebP are supported by the secure pasted-image path.
Claude Code can use the Quire plugin to forward original pasted-image bytes. The connection must be named quire. The plugin uses a two-minute, one-use token encrypted to an ephemeral key; plaintext upload tokens, private keys, and image bytes do not appear in model-visible tool output. Pasted images are limited to 10 MiB and 64 megapixels.
Cursor, claude.ai, and other clients can still attach images from public URLs, base64, or existing Quire images, but automatic forwarding of chat-pasted images is currently Claude Code-only.
Collection files
Collection files can hold reference material such as PDFs, spreadsheets, and source documents. MCP tools provide metadata, viewer access, attachment references, movement, Trash, and restore behavior. Quire issues short-lived signed download URLs when an authorized agent needs bytes.
Keep durable conclusions in Markdown documents even when source evidence lives in an attached file. This makes the knowledge searchable and easier for future agents to use.
