# Toolporten Background Remover — full

Toolporten is an MCP toolboxes product. The public Background Remover is a separate
consumer surface on the same host: website https://www.toolporten.com/remove-bg and remote MCP https://www.toolporten.com/mcp/remove-bg.

## MCP connect

Add this one URL in Grok, Claude, ChatGPT, or Cursor:

https://www.toolporten.com/mcp/remove-bg

OAuth 2.1 + PKCE + DCR. Discovery: 401 WWW-Authenticate →
https://www.toolporten.com/.well-known/oauth-protected-resource/mcp/remove-bg →
https://www.toolporten.com/.well-known/oauth-authorization-server/mcp/remove-bg →
https://www.toolporten.com/oauth/register → Clerk consent. Scope mcp:tools. Resource is the MCP URL.

## Recipes

1. Grok: Custom Connector → paste the MCP URL → sign in with Clerk.
2. Claude: Add connector → paste the MCP URL → allow Background Remover.
3. ChatGPT: Add MCP / connector → paste the MCP URL → complete OAuth.

Agent loop (do not paste image base64 — Grok and others choke stuffing JPEGs through the model):

1. media_upload_session_create → tell the human to open uploadPageUrl (/u/{token})
2. media_upload_session_status until Ready
3. image_remove_background with uploadSessionId (optional background: transparent, white, or hex)

Or pass image_url (public http/https) to image_remove_background.

## Tool

id: image_remove_background
Also: media_upload_session_create, media_upload_session_status
Arguments: uploadSessionId (preferred, Ready session) or image_url (public http/https).
Optional background: transparent (default, keep alpha), white, or a hex color (#RGB, #RRGGBB, #RRGGBBAA).
Flatten is the same removal — not a second pack credit. Do not send image / base64. Max 15 MiB / 8192 px.
Private, loopback, link-local, and reserved addresses are rejected.

## Limits

Signed-in (website session or this MCP OAuth): 5 free removals per UTC day.
Anonymous website: 3 free / UTC-day. $5 USD 10-pack. Pro unlimited on this product only.
Toolbox MCP /mcp/{toolboxId} is unchanged (2 credits). Do not merge anonymous packs onto login.

## Kill switch

REMOVE_BG_PUBLIC off hides the website and this MCP (404).
