Use Cases

Real-world ways to use api-gateway-skill

Pull today's HubSpot deals and post a brief to Slack

👤 Sales ops, founders running their own revenue reporting ⏱ ~15 min beginner

When to use: You want a daily 'what moved in the pipeline' without logging into HubSpot.

Flow

Query HubSpot

Use api-gateway-skill. Pull deals updated today with a stage change in HubSpot. Include owner, amount, new stage.✓ Copied

→ Slack-flavored markdown
Post

Post to #sales-daily.✓ Copied

→ Message posted; link returned

Pitfalls

Overposting when the pipeline is quiet — Ask Claude to skip posting on days with zero stage changes

Export yesterday's Shopify orders to a Google Sheet

👤 E-commerce ops teams using spreadsheets for reporting ⏱ ~10 min beginner

When to use: You want a daily running sheet without a Shopify app install.

Flow

Pitfalls

👤 AE / CS teams that discuss customers in Slack but report in SFDC ⏱ ~20 min intermediate

When to use: You want customer context from multiple sources without swiveling.

Flow

Summarize and write back

Summarize into a 3-bullet note and append to the ACME account in Salesforce.✓ Copied

Tools

What this MCP exposes

Tool	Inputs	When to call	Cost
gateway_call	vendor, endpoint, params	Any cross-vendor operation	1 Maton API call
list_connections	none	Checking what's available before a workflow	1 call

Cost & Limits

What this costs to run

API quota: Per Maton plan — typically thousands of calls/day on paid tiers
Tokens per call: 200–500 per vendor call
Monetary: Maton has a free tier; paid tiers scale with call volume
Tip: Batch reads where possible; each call counts.

Security

Permissions, secrets, blast radius

Minimum scopes: Vary per vendor — scoped to what you connect

Credential storage: Single Maton API key in env var (e.g. MATON_API_KEY); vendor tokens stored server-side by Maton

Data egress: Maton's API, then to the connected vendors

Never grant: Admin scopes you don't need

You're trusting Maton as an OAuth broker. Review their security docs and SOC2 posture before connecting production systems.
Rotate the Maton API key periodically. Revoke vendor connections from the Maton dashboard when no longer needed.

Troubleshooting

Common errors and fixes

401 from gateway_call

Maton API key wrong or expired; regenerate in Maton dashboard

Verify: curl -H "Authorization: Bearer $MATON_API_KEY" https://api.maton.ai/v1/connections

Vendor-specific error bubbles up

Maton passes vendor errors through. Check the vendor's docs for the error code.

Connection missing a scope

Reconnect the vendor in Maton UI and grant the needed scope
