MCP support
Exposes TinyPNG image-compression, transformation, download and usage tools to MCP clients through a hosted remote MCP server. Authentication uses OAuth with the user's TinyPNG credentials.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

From the project READMETinyPNG MCP by usefulapi
Use TinyPNG from Claude, Cursor, or any MCP client — compress an image by URL, resize or convert the result (WebP, AVIF, PNG, JPEG), download it, and check how many compressions your key used this month. Hosted, no local install: connect with your own TinyPNG credentials.
Live endpoint: https://tinypng.usefulapi.io/mcp · Homepage: https://usefulapi.io/tinypng
Connect
- Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste
https://tinypng.usefulapi.io/mcp. - Claude Code:
claude mcp add --transport http tinypng https://tinypng.usefulapi.io/mcp, then run/mcpto log in. - VS Code: Add to VS Code.
- Cursor and other clients: add the URL as a remote MCP server:
{
"mcpServers": {
"tinypng": {
"url": "https://tinypng.usefulapi.io/mcp"
}
}
}
Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your TinyPNG credentials.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
