How to connect MuAPI to OpenClaw (paste one key, 5 tools)

The usual route to MuAPI 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 MuAPI setup: install one ClawHub skill, connect MuAPI in the browser, and OpenClaw can call real MuAPI actions from any chat surface with no auth, token refresh, or tool wiring to build yourself.

Setup

It takes three steps to connect OpenClaw to MuAPI.

1
Install 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 MuAPI
Paste your API key in the dashboard.
3
Use it from chat
Ask OpenClaw: "What can you do with MuAPI?"

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-plugin

Then 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 MuAPI in the ClawLink dashboard — paste your MuAPI API key once.

Verify the connection by asking OpenClaw:

Use MuAPI to estimate model cost and walk me through the result in plain English.

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 login

login opens the same browser approval and stores a credential locally. Once MuAPI is connected in the dashboard, that agent calls the same 5 MuAPI tools over MCP. Full setup for MCP clients and shell agents: connect apps to any AI agent.

MuAPI MCP for OpenClaw

Looking for a MuAPI MCP server for OpenClaw? ClawLink connects MuAPI to OpenClaw and exposes 5 MuAPI tools your agent can call over MCP, with hosted auth and nothing to run or maintain yourself. Using Hermes instead? The Hermes MuAPI integration works the same way.

What the OpenClaw MuAPI integration can do

5 MuAPI tools are ready for OpenClaw once the account is connected.

All 5 MuAPI tools for OpenClaw

Tool	What it does
Estimate model cost `muapi_estimate_model_cost`	Price a native catalog model run before submitting it
Get catalog model `muapi_get_catalog_model`	Get one native catalog model by name, including its pricing and the provider-defined input and
List catalog models `muapi_list_catalog_models`	Browse MuAPI's full native model catalog with per-model pricing, category, family and group
List models `muapi_list_models`	Return the image-generation models available through MuAPI's OpenAI-compatible API
Generate image `muapi_generate_image`	Generate one or more images from a text prompt through MuAPI's OpenAI-compatible API

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 MuAPI working from chat.

	Manual	ClawLink
Credential handling	Collect, validate, store, and rotate the MuAPI API key yourself, then make sure every tool call uses the right account.	Users complete the hosted ClawLink setup once and the connected MuAPI 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 MuAPI.	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 MuAPI actions to the runtime in a format your agent can reliably use.	5 tools for MuAPI are already exposed through ClawLink, so the agent can read and act from chat immediately.

ClawLink vs. Composio

Composio also exposes MuAPI 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 MuAPI in the browser, and the 5 tools above work from chat. There is no SDK and no config file, and the MuAPI key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Troubleshooting

OpenClaw installed the MuAPI skill but can't call the tools

The ClawHub skill teaches OpenClaw about MuAPI, but the calls run through the ClawLink plugin and your connected account. Make sure MuAPI 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 MuAPI 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 MuAPI tools

MuAPI 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 MuAPI 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.

MuAPI 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 MuAPI 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 MuAPI integration?

Yes. ClawLink is the fastest way to connect OpenClaw to MuAPI: link your MuAPI account once in the browser and OpenClaw can call the MuAPI API through 5 ready-made tools — no custom code or token handling.

How do I add MuAPI to OpenClaw with ClawLink?

Paste the setup prompt from this page into OpenClaw. It installs the ClawLink MuAPI skill from ClawHub, then you click Connect in the dashboard to authorize MuAPI. OpenClaw calls the tools from the next message — no config files, and the MuAPI key you paste is stored server-side instead of in your environment.

How long does it take to connect MuAPI to OpenClaw?

About two minutes. Sign in, click Connect next to MuAPI in the dashboard, authenticate, and OpenClaw can use it from the next chat message.

Why use ClawLink instead of wiring MuAPI up myself?
