# MCP tool reference

1 callable tools.

Use tools/call at https://mcp.schedulerzero.com/mcp with the exact tool name and arguments below. The /tools/ paths in this view are documentation identifiers, not HTTP endpoints. Request execution is disabled for this reference.

Inputs are shown for personal API keys (bound) and for OAuth/delegated agents. Output schemas describe MCP structuredContent: native objects pass through; arrays, scalars and null use a data wrapper. Text content retains the native JSON result.

## manage_verification_preferences

Read or update the workspace's email-verification sharing posture: communal-cache mode, strict catch-all, freshness window, and provider display.

Use to audit or change how verdicts flow into the communal cache and how aggressively catch-all verdicts escalate.

Does not manage keys or run verification; payment mode is locked to BYOK.

Obtain the user's explicit authorization before invoking a write or destructive action. This is a client interaction requirement, not a server-issued approval token.

Scopes: emailVerification:manage_sharing, emailVerification:read

Risk: write; confirmation: explicit; idempotency: supported.
