How to connect TinyPNG to OpenClaw
Connect TinyPNG to OpenClaw with ClawLink: paste your TinyPNG key once and 5 tools work from chat. No MCP server to run, nothing stored on your machine.
TinyPNGAPI KEYMCPCompress and optimize images via the TinyPNG API. Once connected, OpenClaw can read and act on TinyPNG from chat — pairing, token refresh, and tool wiring handled for you.
The usual route to TinyPNG access for OpenClaw is an MCP server you configure and keep running, plus your own OAuth app or API keys. ClawLink gives OpenClaw a more practical TinyPNG setup: install one ClawHub skill, connect TinyPNG in the browser, and OpenClaw can call real TinyPNG actions from any chat surface with no auth, token refresh, or tool wiring to build yourself.
Copy this prompt into OpenClaw, or open the TinyPNG skill on ClawHub.
Before installing anything, inspect the ClawHub skill metadata and setup requirements.
If the skill asks you to install a third-party package or CLI, verify its source, maintainer, and package contents before running the install command.
Install the skill "TinyPNG" (hith3sh/tinypng-workspace) from ClawHub only after those checks pass.
Skill page: https://clawhub.ai/hith3sh/tinypng-workspace
Keep the work scoped to this skill only.
After install, help me finish setup from verified skill metadata.
Use only the metadata you can verify from ClawHub; do not invent missing requirements.
Ask before making any broader environment changes.Setup
It takes three steps to connect OpenClaw to TinyPNG.
1Install the plugin
Paste the setup prompt into OpenClaw, or install from the terminal and ask OpenClaw to pair:
openclaw plugins install clawhub:clawlink-plugin- 2
Connect TinyPNG
Paste your API key in the dashboard.

Use it from chat
Ask OpenClaw: "What can you do with TinyPNG?"
Install by command
The setup prompt above does all of this in one paste. By hand, it is one install command plus a browser approval:
openclaw plugins install clawhub:clawlink-pluginThen ask OpenClaw to set up ClawLink. It starts browser pairing and prints an approval link — open it, approve the device, return to the chat, and say done. Finally, connect TinyPNG in the ClawLink dashboard — paste your TinyPNG API key once.
Verify the connection by asking OpenClaw:
Pull the relevant data from TinyPNG, summarize it in plain English, and point out anything that needs attention.
Using a different agent?
The OpenClaw plugin is one client of ClawLink's MCP server. Claude Code, Cursor, Codex, or any agent that can run a shell command pairs with the same ClawLink account through the CLI:
npx -y @useclawlink/cli loginlogin opens the same browser approval and stores a credential locally. Once TinyPNG is connected in the dashboard, that agent calls the same 5 TinyPNG tools over MCP. Full setup for MCP clients and shell agents: connect apps to any AI agent.
TinyPNG MCP for OpenClaw
Looking for a TinyPNG MCP server for OpenClaw? ClawLink connects TinyPNG to OpenClaw and exposes 5 TinyPNG tools your agent can call over MCP, with hosted auth and nothing to run or maintain yourself. Using Hermes instead? The Hermes TinyPNG integration works the same way.
What the OpenClaw TinyPNG integration can do
5 TinyPNG tools are ready for OpenClaw once the account is connected.
All 5 TinyPNG tools for OpenClaw
| Tool | What it does |
|---|---|
Get compression count tinypng_get_compression_count | Tool to retrieve the number of compressions made this month. Use when you need to monitor your TinyPNG API usage. |
Shrink and get image ID tinypng_shrink_and_get_image_id | Tool to shrink an image and return its TinyPNG image ID. Use when you need only the compressed image identifier from the API response Location header. |
Tinify compress and store in azure tinypng_tinify_compress_and_store_in_azure | Compress an image using the Tinify API and upload the optimized result directly to Azure Blob Storage in a single operation. |
Tinify output tinypng_tinify_output | Tool to retrieve a compressed image by its image ID. Use after compressing an image to download the result. |
Transform image tinypng_transform_image | Tool to transform a compressed image by resizing, converting format, preserving metadata, or storing to cloud storage. |

ClawLink vs. building it yourself
The alternative to ClawLink is usually manual API key setup plus your own token handling, permission troubleshooting, and tool plumbing for OpenClaw. That is fine if you want to build and maintain the integration yourself. Most teams just want TinyPNG working from chat.
| Manual | ClawLink | |
|---|---|---|
| Credential handling | Collect, validate, store, and rotate the TinyPNG API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected TinyPNG account becomes available to the agent without you building credential management. |
| Ongoing maintenance | You own refresh logic, permission debugging, environment config, and every provider-specific edge case for TinyPNG. | ClawLink handles the repetitive integration plumbing so your team can focus on the workflow instead of the infrastructure. |
| Agent usability | You still need to expose the right TinyPNG actions to the runtime in a format your agent can reliably use. | 5 tools for TinyPNG are already exposed through ClawLink, so the agent can read and act from chat immediately. |
ClawLink vs. Composio
Composio also exposes TinyPNG to AI agents. It is developer infrastructure: Python and TypeScript SDKs, an MCP server, and a catalog past 1,000 apps, aimed at teams shipping agent products. ClawLink is built for OpenClaw users instead. You install the plugin once, connect TinyPNG in the browser, and the 5 tools above work from chat. There is no SDK and no config file, and the TinyPNG key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Troubleshooting
OpenClaw installed the TinyPNG skill but can't call the tools
The ClawHub skill teaches OpenClaw about TinyPNG, but the calls run through the ClawLink plugin and your connected account. Make sure TinyPNG is connected in the dashboard, then start a fresh chat so OpenClaw reloads the tool catalog. If OpenClaw runs as a persistent gateway, restart it so the new tools register.
Connection succeeds but no tools appear
Reconnect TinyPNG from the dashboard, then start a fresh chat if the runtime still has the old tool catalog loaded.
"Tool schema not loaded yet" error when calling TinyPNG tools
TinyPNG tool schemas load on demand the first time a tool runs and are cached after that, so this error usually clears on its own: wait a few seconds and retry the same request. If every TinyPNG call keeps failing with it in a fresh chat, reconnect from the dashboard, and contact support if it still persists — that pattern points to a configuration problem on our side, not something you can fix by reconnecting again.
TinyPNG returns 403 or "permission denied" on one action while others work
Two usual causes. The connected account may not have access to the specific workspace, inbox, store, or project in the request — check that first. If access looks right, the agent may have sent a placeholder value (like "YOUR_ID" or an example id from documentation) instead of a real one: ask it to run a list or search tool first, then retry the action with a real id from those results. Most failures at this stage are one of these two, not ClawLink bugs.
API key setup works but results look incomplete
Double-check that the API key for TinyPNG has the right scopes or account access. A valid key can still be too limited for some reads or writes.
FAQ
Is there a OpenClaw TinyPNG integration?
Yes. ClawLink is the fastest way to connect OpenClaw to TinyPNG: link your TinyPNG account once in the browser and OpenClaw can call the TinyPNG API through 5 ready-made tools — no custom code or token handling.
How do I add TinyPNG to OpenClaw with ClawLink?
Paste the setup prompt from this page into OpenClaw. It installs the ClawLink TinyPNG skill from ClawHub, then you click Connect in the dashboard to authorize TinyPNG. OpenClaw calls the tools from the next message — no config files, and the TinyPNG key you paste is stored server-side instead of in your environment.
How long does it take to connect TinyPNG to OpenClaw?
About two minutes. Sign in, click Connect next to TinyPNG in the dashboard, authenticate, and OpenClaw can use it from the next chat message.
Why use ClawLink instead of wiring TinyPNG up myself?
The alternative to ClawLink is usually manual API key setup plus your own token handling, permission troubleshooting, and tool plumbing for OpenClaw. That is fine if you want to build and maintain the integration yourself. Most teams just want TinyPNG working from chat.
