Overview

AI-generated overview

Remote MCP server that lets an assistant turn a user's own photos into shape collages (hearts, numbers, words) or photo mosaics, returning watermarked previews.

What you can do
Browse collage shapes and mosaic styles with example images and photo counts, and get a plan for a chosen shape before photos are attached. Create a shape collage from the user's photos and retrieve its status and watermarked preview by id. Start a photo mosaic and get the link where the user uploads photos and picks a style on the website.
When to use it
Useful when someone wants a personalized photo gift or keepsake: a heart collage, a birthday or anniversary number, a word or star made of photos, or a mosaic portrait built from a large photo archive.
Requirements
Remote streamable HTTP endpoint; no sign-in, API key, environment variables or headers are needed. The user uploads photos and downloads the full-resolution file on the collager.ai website.
Before you install
Photos are uploaded to a third party and stored in Amazon S3 in the EU; the server states they are deleted 30 days after the job and not used to train models. Chat returns only a watermarked preview, so the finished file must be obtained on the website. No payment or account details are requested by the tools.

Installation

In SourceWeft

  1. Open Photo Mosaic & AI Collage Maker - Collager.ai in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ai.collager%2Fai-collage-maker/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

Photo Mosaic & AI Collage Maker - Collager.ai

A photo mosaic maker and AI photo collage maker for Claude, ChatGPT and any MCP-capable agent. Turn your own photos into:

  • a photo mosaic - one picture (a portrait, a couple, a pet) recreated from hundreds or thousands of your small photos. Zoom in and every tile is a real photo;
  • a photo collage in seconds - a heart, a number (birthday, anniversary, year), a word, "I love you", a star or a flower made of photos.

make_shape_collage

Make a photo collage (heart, number, word...)

Builds a photo collage in the shape of a heart, a number (age, anniversary, year), a word, a star, a flower and more from the user's photos, and returns a watermarked preview within seconds. Use when the user asks for a heart collage, a birthday/anniversary number collage, a 'photo collage in the shape of ...', or a collage from several photos. Pass the photos as public links in photo_urls, or as files the user attached (photos). 1 to 300 photos; if there are fewer photos than cells, photos repeat. The result id (clg_...) is a private handle valid for 30 days; photos and results are deleted after 30 days. The preview is watermarked; the full-resolution file is downloaded from the collager.ai page given in full_resolution_page. Building can take up to a minute - if status is still processing, call get_shape_collage with the id.

Parametersshaperequiredphotosgap_pctbackgroundphoto_urls

get_shape_collage

Check a shape collage

Returns the status and the watermarked preview of a collage made with make_shape_collage, by its id (clg_...). Use when make_shape_collage answered status "processing", or to show the collage again.

Parametersidrequired

list_collage_shapes

List collage shapes

Shows the menu of Collager.ai photo collages with a real example: the shapes make_shape_collage can draw (hearts of 27-164 photos, numbers, words, I love you, circle, star, flower, grid, your own mask) and how many photos fill each without repeats. Call it first when the user only mentions Collager.ai, says hello to it, or asks what it can make.

Takes no parameters.

plan_shape_collage

Plan a photo collage

Shows the plan of the photo collage the user picked (shape, how many photos it holds, background) with a real example, and how to attach the photos. Use it when the user has chosen a shape but has not attached the photos yet. After the user attaches the photos or shares links, call make_shape_collage with the same shape and background.

Parametersshaperequiredbackground

list_mosaic_styles

Show photo mosaic styles

Shows the looks of a Collager.ai photo mosaic (one large picture made of hundreds or thousands of small photos) with example images: soft classic, clean subject, stronger mosaic, uniform or mixed tile sizes. Use before start_photo_mosaic when the user wants to choose a style.

Takes no parameters.

start_photo_mosaic

Start a photo mosaic on collager.ai

Gives the link where the user builds a photo mosaic: one main photo recreated from many small photos (best with 100-2000 photos - family archive, wedding, team, school year). The user uploads the photos on collager.ai, picks the style, and the site builds a watermarked preview in minutes. Call it only after the user has decided to make a photo mosaic; to show the options first, use list_mosaic_styles.
