Each tool has a clearly distinct purpose targeting specific security policy controls - blocking sign-ins vs. users, configuring different admin workflows, enforcing various MFA methods, restricting different consent types. The descriptions with MS.AAD codes further clarify boundaries, leaving no ambiguity about which tool to use for each security requirement.

All tools follow a consistent verb_noun pattern using snake_case throughout - every tool starts with an action verb (block, complete, configure, disable, enforce, get, restrict) followed by a specific noun phrase describing the security control. This creates a highly predictable and readable naming convention across all 21 tools.

21 tools is slightly high but reasonable for the comprehensive CISA M365 security policy domain. The server covers authentication methods, admin controls, application consent, and privileged access management - each area requiring multiple specific controls. While borderline heavy, each tool addresses a distinct security requirement that earns its place in the set.

The tool set provides complete coverage for CISA M365 security policy implementation with get_policy_status for assessment and enforcement tools for every major control area: authentication methods (MFA, migration), admin security (global admins, alerts, PAM), and application governance (consent, registration). There are no obvious gaps - agents can implement the full security framework without dead ends.
