Morphic MCP uses a single credential type everywhere: API keys. There is no email, password, user ID, or account ID required.

​
Getting an API key

  1. Log in to app.morphic.io
  2. Go to https://app.morphic.io/home/{workspace}/settings/developers — replace {workspace} with your workspace name
  3. Click Generate new key and give it a label
  4. Copy the key — it is shown only once

​
Using your API key

Pass the key in either header on every request:
Account and workspace context are derived automatically from the key. You never need to supply an account ID or workspace ID separately.

​
How validation works

The MCP server validates every key by calling GET /api/accounts/me on the Morphic backend. Results are cached in memory for 2 minutes per token to avoid a round-trip on every tool call.

​
Claude.ai web connector (OAuth)

Claude.ai’s web connector uses OAuth 2.0 + PKCE — it cannot store a static API key directly. The MCP server bridges this:
1

Connect in Claude.ai

Add https://mcp.morphic.io/v1/mcp as a connector. Claude.ai opens an OAuth flow.
2

Enter your API key

You’ll be redirected to a Morphic page. Paste your sk_live_... key and click Connect.
3

Done

Claude.ai stores the key. All future tool calls use it as a bearer token — identical to every other client.
The MCP connector never asks for your email or password. If you see an email/password form, you are on the regular Morphic app login page, not the MCP connector.

​
Revoking a key

Revoke any key at https://app.morphic.io/home/{workspace}/settings/developers. The MCP server rejects it within 2 minutes (the cache TTL).
