This guide walks you through connecting Axiom to an OpenClaw agent. OpenClaw uses mcporter to handle OAuth authentication and scope your agent's access to only the MCP tools it needs. Once connected, your agent can check your payment method, make purchases, and log receipts through Axiom.
What you'll need
- An OpenClaw account with at least one configured agent
- mcporter v0.8.0 or later on your agent's PATH (check with
mcporter --version) - A headless browser CLI so your agent can read the activation URL from the rendered OAuth page. Either works:
- Recommended:
agent-browser(Rust native, fast, no Python needed) —npm install -g agent-browser && agent-browser install - Alternative:
browser-use(Python) —uv add browser-use
- Recommended:
- An Axiom account with a linked payment method and spending rules configured
Step 1: Install the Axiom Wallet skill
The easiest way to get started is to point your agent to the Axiom Wallet skill on ClawHub. Tell your agent:
"Set up Axiom Wallet. Follow the guide at docs.useaxiom.ai."
Your agent will install the skill and prepare for authentication. The skill is also available directly on ClawHub at clawhub.ai/axiom-wallet/axiom.
Step 2: Authenticate with mcporter
Your agent registers Axiom and starts the OAuth flow:
Register Axiom
mcporter config add axiom --url https://mcp.useaxiom.ai/mcpStart authentication
mcporter auth axiom --reset --oauth-timeout 300000 --log-level infomcporter prints the OAuth authorize URL in its log output. Your agent opens that URL with its headless browser and reads the activation URL off the rendered page. The two are different: the agent navigates to the authorize URL, and only the activation URL is for you. Your agent will send you the activation link with instructions to open it and allow the connection.
Step 3: Allow the connection
Open the link your agent provided and sign into Axiom if needed. The connect screen names the app you're connecting and says what it will be able to do:
- Place orders for you, within the limits you set
- Check how each order is going and share your receipts
- See your name and which card is on file (last 4 digits only)
Your agent never sees your full card number. Axiom pays each store with a one-time card made for that order. The permissions reference lists exactly what sits behind each line.
Click Allow. The browser confirms the connection automatically, and your agent continues where it left off.
Ask for only what your agent will use. An agent that only browses or tracks prices doesn't need permission to place orders.
Step 4: Verify the connection
Ask your agent:
"Check my Axiom payment method."
If your agent calls the get_payment_method tool and returns your card brand and last four digits, the connection is live.
You're all set!
Your OpenClaw agent can now make purchases through Axiom. Every transaction generates a single-use virtual card, checks your spending rules, and logs a full audit trail.

Troubleshooting
- "mcporter: command not found." Make sure mcporter v0.8.0+ is installed and on your PATH.
- OAuth times out. The default timeout is 5 minutes. Open the activation URL promptly after your agent sends it.
- Agent can't find Axiom tools. Confirm the skill installed correctly and that authentication completed. Re-run the mcporter auth command if needed.
- Purchase blocked. Check that your spending rules allow the category and amount your agent is trying to purchase.
