What

Part of a pass over every API surface.

A scoped API key on the MCP server has to read the families an investigation reads (traces, logs, metrics, services, alerts and so on). Twenty-four tools work on data outside those families, and until now only three tools declared the extra scope they need. This adds the declaration to the rest:

Tools	Scope family
list_slos, inspect_slo, create_slo, update_slo, delete_slo	slos
list_uptime_monitors, create_, update_, delete_uptime_monitor	uptime_monitors
list_ingest_rules, preview_ingest_rule, create_, update_, delete_ingest_rule	ingest_rules
list_data_sources, search_data_sources, describe_data_source, query_data_source	data_sources
get_status_page	status_pages and status_page_incidents
apply_status_page_config	status_pages
post_status_page_update	status_page_incidents
create_, update_, delete_scrape_target	scrape_targets

A read-only tool needs <family>:read, a tool that changes data needs <family>:write, the same as the matching /v2/<family> routes. A tool can name several families, and the refusal names the scope to add.

So that a restricted key can be given those scopes, the key dialog and the scope reference on Settings, Keys now list six more families: SLOs, uptime monitors, ingest rules, data sources, status pages and status page incidents. Until now those could only be granted through the API.

Unscoped keys, MCP OAuth tokens, dashboard sessions and chat turns carry no scopes and are unchanged.

Screenshots

Key dialog
Scope reference

Verification

• scope-families.test.ts: a key holding every baseline family is refused by each of the 24 tools with insufficient_scope and the right scope in the message; a read scope does not open a tool that writes; get_status_page asks for both of its families.
• The whole apps/ai/src/mcp suite and the web settings tests pass.
• Typecheck @maple/ai and @maple/web, lint with the CI config.
• On the preview: the dialog shows "0 of 27 selected" and the reference "27 resource families", with the six new rows.

Walkthrough

MCP tool registrations now declare scope families for data sources, ingest rules, scrape targets, SLOs, status pages, and uptime monitors. Tests check insufficient-scope errors and verify that create_slo requires slos:write.

Tool registrations specify their scope families. Tests check that calls fail with insufficient scopes and that create_slo requires slos:write.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: Moderate · up to 73bed

Dashboard users who create restricted API keys cannot grant the new scopes, so those keys lose access to the SLO, ingest-rule, data-source and status-page tools that previously worked. Full-access keys, MCP OAuth tokens and keys created through the API are unaffected. Add the five families to the key-creation flow before merging.

Full details: Title check

Explanation

The title names the main change: MCP tools outside the baseline API families now require their own scope. The changeset adds scopeFamily declarations to the listed MCP tools (SLOs, data sources, ingest rules, status pages, uptime monitors, scrape targets) and adds tests that check the insufficient-scope refusal. The title is specific to that change and does not describe unrelated work.

Maple review

🟢 Confidence 8/10 · likely safe to merge. Refusal path is pinned for all 24 tools, but nothing ties the demanded families to the grantable ones in Settings, where this branch already drifted once.
_{no findings · tests partial −1 · risk high −1}

The change gives 24 MCP tools their own scope families, lets scopeFamily list several, and exposes six families in Settings. The McpQueryError issues in registry.ts are query failures this diff does not touch.

• 24 MCP tools now declare a scope family outside the baseline set
• scopeFamily accepts a list; get_status_page requires both status-page families
• Six new families added to the key dialog and scope reference

Before merge

• Manual · Restricted keys calling these 24 tools today get insufficient_scope after the deploy until the new scopes are added to them.
