Honor enabled providers in MCP spend listing

[tsouth89]

Summary

• get_spend without a provider and list_providers.local_spend_supported now follow Ceiling's enabled-provider set instead of scanning every local-log provider.
• Explicit provider= still scans Codex/Claude/Grok even when that provider is disabled, matching CLI --provider.

Fixes SBS-958.

Test plan

• cargo test --manifest-path rust/Cargo.toml --lib -- mcp::

Made with Cursor

Note

Filter MCP spend and status results by enabled providers in Settings

• MCP tools (list_providers, get_spend, get_status) now respect the enabled providers configured in Settings, so disabled providers are excluded from auto-selected scans and status results.
• A new enabled_provider_ids helper centralizes reading enabled providers from Settings and passes them through to payload functions.
• When a provider is explicitly specified by the user, spend and status still proceed if the scanner supports it, regardless of whether the provider is enabled.
• Behavioral Change: choose_status_provider may now return None if all snapshot entries belong to disabled providers, yielding a null provider/usage in the status response.

📝 Walkthrough

Walkthrough

MCP provider listing, spend, and status logic now reads enabled providers from Settings. Automatic scans use only enabled locally scannable providers. Explicit requests can still access supported providers when disabled. Tests cover these rules.

Changes

MCP provider filtering

Layer / File(s)	Summary
Provider configuration and listing rust/src/cli/mcp.rs	The MCP CLI loads enabled provider IDs from Settings. Provider listing and local-spend support use the enabled-provider set.
Spend provider selection rust/src/cli/mcp.rs	Automatic spend scans select enabled locally scannable providers. Explicit requests validate local scanning without requiring the provider to be enabled.
Status selection and validation rust/src/cli/mcp.rs	Automatic status lookups select enabled providers. Explicit status requests allow supported locally scannable providers. Tests cover disabled snapshot providers, disabled Grok access, and invalid providers.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to b6612

Automatic status requests may still return data from providers disabled in settings, causing default results to violate the enabled-provider configuration. This bounded correctness issue should be fixed or explicitly accepted before merging.
