# 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_lead_contact_points

Mark contact points bad/active (action=set_status) or reorder them (action=reorder); position 1 is the scalar mirror.

Use to correct bad contact data or reprioritize outreach order on one lead.

Reactivation of a call_disposition phone restores dialer wrong-number state — it is not silent.

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: lead:update

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