Claude Integration
Overview
AI Integration lets you connect AI tools like Claude to 3Min API, so you can run your endpoints with the same kind of casual chat you already use. Behind the scenes it speaks MCP (Model Context Protocol), an open standard. Once the AI is connected to the 3Min API server, it picks the right tool from the ones we expose and answers your question.
The benefit is concrete. No code is needed to create a new endpoint, search yesterday's call logs, invite a collaborator, or check this month's usage. Skip the dashboard clicks — "Summarize the 5 failed calls from last week" is enough.
3Min API supports two authentication styles. ChatGPT and Claude use OAuth (sign in with your 3Min API account), so there's no API key to manage. CLI/IDE tools like Claude Code or Cursor use API keys that you store locally. This page walks you through connecting via Claude's custom connector.
What you can do
The 3Min API MCP server exposes the tools below. The AI looks at your request and picks the right one. Every action is scoped to your own account — other users' resources are never accessible.
Read tools
| Tool | Description | Scope |
|---|---|---|
help |
Returns the 3Min API service guide by topic | Public |

subscription |
Current plan, usage, and billing info | Your account |
archives (list / download) |
Archive file list + temporary download URL | Your own |
collaborators (list_keys / list_invitations) |
Collaboration keys and invitation list | Your own |
Create / Update / Deploy tools
| Tool | Description | Scope |
|---|---|---|
endpoints (create) |
Create a new endpoint | Your account |
endpoints (update) |
Update field definitions, webhooks, and notifications | Your own |
endpoints (deploy) |
Deploy sandbox config to production | Your own |
collaborators (create_key) |
Create a new collaboration key | Your own |
collaborators (update_permissions) |

Execution tools
| Tool | Description | Scope |
|---|---|---|
api_call (GET / POST / PUT / DELETE) |
Send an HTTP request to your deployed endpoint (via the gateway) | Your own |
The
DELETEinapi_callinvokes the business logic of your own endpoint (e.g., a "cancel order" API). It does not delete the endpoint itself.
Safety: actions intentionally not exposed to AI
The actions below are deliberately excluded from MCP. We don't want an AI mistake or accidental call to wipe data or trigger billing surprises. When you need to do these, sign in to https://3minapi.com directly.
| Excluded action | Where to perform it |
|---|---|
| Delete endpoint | Dashboard → APIs → Endpoint detail |
| Delete / deactivate collaboration key, regenerate API key | Dashboard → APIs → Endpoint detail → Collaboration keys |
| Revoke collaborator invitation | Dashboard → APIs → Endpoint detail → Collaborators |
| Change / cancel plan | Dashboard → Settings → Subscription |
| Regenerate / delete MCP API key | Dashboard → Settings → AI Integration → CLI / IDE |
| Delete archive file | Dashboard → APIs → Archives |
| Delete account | Dashboard → Settings → Profile |
How to connect
Claude uses the OAuth flow. You only register a server URL on the custom connector — the rest is handled by signing in with your 3Min API account. No API key to enter manually.
Step 1 — Open Claude settings
Open Claude at https://claude.ai, then go to Settings from the account menu in the top-right.
Step 2 — Go to Connectors
In the settings sidebar, choose the Connectors section.
Step 3 — Add a custom connector
Click Add Custom Connector and fill in the fields below:
Connector Name:
3minapi(any name you like)Server URL:
https://3minapi.com/api/mcp
Step 4 — Connect, then sign in via OAuth
When you click Connect, the 3Min API login page opens in a new window. Sign in with your usual 3Min API account and permissions are granted automatically.
Step 5 — Use it in a new chat
Open a new chat and start using it.
Claude Free lets you register 1 custom connector. Pro and above is unlimited.
Example prompts
These plain-language prompts work well:
- "Show me my API endpoint list."
- "Create an endpoint for customer inquiries with name, email, and message fields."
- "Summarize the 5 failed calls from yesterday."
- "How much have I used this month, through yesterday?"
- "Invite chris@example.com as a collaborator on the user-signup endpoint."
For requests that create, update, or deploy something, the AI confirms with you before going through. Read the response carefully so unintended changes don't slip in.
Common pitfalls
I clicked Connect but no tools showed up
Claude's connector cache occasionally takes a moment to refresh. Disconnect the connector and reconnect — the tool list should appear cleanly in a new chat.
I'm on the Free plan and can't add a connector
You probably already have one custom connector registered. The Free plan caps you at one — remove the existing connector or upgrade to Pro or above.
What if someone else's data gets mixed in?
It can't. Every tool only touches resources owned by the OAuth-signed-in account — other users' endpoints, logs, and archives are never visible.
The AI deleted my endpoint!
It can't. Destructive actions are excluded from MCP, so no matter how the AI tries, your data stays put. To actually delete something, sign in to https://3minapi.com.
Does Claude Code (terminal) connect the same way?
No. Claude web / desktop uses an OAuth-based custom connector, while Claude Code (CLI) and Cursor and similar local tools use the API key flow. For those, see the MCP integration (CLI / IDE) guide.
