# 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. [Connect a client](/mcp/connect) · [Authentication and authorization](/authentication) · [Generated auth guide](/auth.md) · [Download tool catalog](/mcp-catalog.json) · [Agent documentation](/llms.txt) ## revoke_api_key Revoke one of the caller's personal API keys: preview first, then commit with the returned confirmation token. Use when the person asks to shut off one of their keys. Revocation is immediate and cannot be undone; every integration using the key stops authenticating. To stop a member's key in one Organization only, use block_organization_api_key. Use the native preview first and pass its confirmation token unchanged to commit. A token does not bypass current permissions or Workspace checks. Scopes: apiKey:delete Risk: destructive; confirmation: preview_token; idempotency: required. ### Input schema (personal API key) ```json { "type": "object", "properties": { "apiKeyId": { "type":
