  1. Enable Dictionary API in Metorial. In your Metorial portal, enable the Dictionary API MCP server and sign in with the account that owns the data. Access stays governed by your team policies.
  2. Add a custom connector. Open Customize, then Connectors. Select Add, then Custom, then Web.
  3. Paste your Metorial MCP URL. Name it Metorial, paste your Magic MCP URL (<your-magic-mcp-url>) and continue.
  4. Sign in. Select Add and sign in to load Dictionary API tools.

Run Dictionary API through the Metorial gateway

One governed layer for every app your agents reach, not a separate connector per tool.

  • Give Dictionary API and every other app to your whole team through one MCP gateway, behind your SSO.
  • Scope which teams and agents can use Dictionary API tools with role-based access control, and trace every call.
  • Prefer to run it yourself? Metorial is open source and self-hostable.
