Stable aliases
Application code references /m/org/project/path — a role, not a version UUID. Replacing the file does not change the URL.
Web Assets
Permanent web assets for applications
Your AI builds the site. DropIMG hosts the files the site actually serves — with role-based URLs that do not change when the bytes do.
Replace in place
A new version is stored; the alias stays. Default to the alias in <img>, favicons, CSS, and @font-face. Pin ?v= only for audits.
Built for agents
MCP and REST use the same write path. The agent mints an upload intent, POSTs bytes over HTTP, and puts the returned alias in your app.
How it works
Step 1
Create a project
Sign in and start a Free Web Assets project. Humans stay on the account; agents get OAuth or a project key.
Step 2
Upload over HTTP
The agent starts a short-lived upload intent, then POSTs the file. Bytes never travel in JSON-RPC.
Step 3
Use the alias
Drop the returned /m/… URL into application code. Next time the asset changes, replace it — do not mint a second path.

Drops vs Web Assets
Drops
Need a quick image URL?
Screenshots, Slack, PRs. Paste it, copy the link, it expires when you choose.
Web Assets
Building an app?
Logos, heroes, favicons, and fonts with stable /m/… URLs that stay put when you replace the file.
| Use case | Drops | Web Assets |
|---|---|---|
| Bug screenshot | Yes | — |
| Slack / PR image | Yes | — |
| Temporary visual share | Yes | — |
| Site logo | — | Yes |
| Homepage hero | — | Yes |
| Favicon | — | Yes |
| Web font | — | Yes |
| Replace asset without changing code | — | Yes |
MCP
One server at https://dropimg.io/mcp. Tools list, create, get, upload, and replace Web Assets. Bytes never travel in JSON-RPC.
REST
Authenticated /api/v1/media for orgs, projects, keys, assets, and upload intents. Same write path as MCP. OpenAPI at /openapi/v1.yaml.
Project keys
Project-scoped dropimg_pk_… credentials. A key cannot create projects. Humans sign in; agents use OAuth or a project key.
Web Assets questions
Is this live in production?
Yes. Sign in and create a Free Web Assets project. Developer and Pro checkout from the pricing page via PayPal. Existing public /m/… URLs keep serving if new uploads have to pause.
Can I host a PDF or a video?
No. DropIMG Web Assets is focused infrastructure for application files, not S3. Use Drops for a temporary screenshot; use Web Assets for the files a website serves.
Do I pay per MCP call?
No. Plans cover projects, storage, and asset deliveries. There is no per-MCP-call fee and no bandwidth surcharge on top of the plan. Fair-use and plan limits still apply.
