Overview
A 56-question diagnostic across 9 domains that evaluates how APIs, events and integration flows are governed, designed, secured, run and retired, including AI agents and MCP servers as API consumers. Written for the head of API and integration platform who needs to answer: are our APIs and integrations known, safe, reliable and worth what they cost?
Detailed Description
APIs and integrations now connect almost every system, partner and AI agent. When they are unknown, inconsistent or weakly protected, they become the easiest path to data loss, outages and wasted spend.
This assessment follows the order in which a dependable API and integration capability is built: a strategy and policy, an operating model, design authority and enabled teams; one inventory checked against runtime traffic, with posture and third-party risk; a design standard, specifications, schemas, contracts and versioning; governed events, reliable delivery, webhooks and integration platforms; tests and pipeline gates; gateways, authentication, authorization, limits, validation and abuse detection; safe use of APIs by AI agents and MCP servers; products, portal, onboarding and partner terms; and resilience, objectives, deprecation, migration and program value.
Questions marked (Bridge) check the link to the model that owns a neighboring practice: Enterprise Architecture, Configuration Management, DevOps Engineering, DevSecOps, Non-Human Identity and Secrets Management, Security Operations, AI Governance, Service Level Agreements and Performance, and SRE, DevOps and ITSM Convergence. Each question is scored on whether the practice is documented, implemented and effective.
Assessment Details
Audience
Head of API and integration platform, enterprise architects, CTO. Secondary: API product owners, integration engineers, API security engineers and platform teams.
Purpose
Shows where APIs and integrations are unknown, inconsistent, exposed or costly, and where AI agents reach systems without the right controls. Gives each gap a concrete next step and a measurable target.
Effort
Initial assessment: 5 to 6 hours of facilitated sessions with architecture, the platform team, provider teams, integration engineers and API security. Evidence gathering: gateway and mesh configuration and logs, inventory and discovery reports, specifications and schemas, pipeline results, integration platform records and portal analytics.
Cadence
Annually, and after a major platform change, a significant API security incident or the introduction of AI agents that call enterprise APIs.
Framework Alignment
KPIs
- Inventory Match to Runtime - Share of APIs observed at runtime that match an inventory record. Target: 95% or higher.
- Unplanned Breaking Changes - Breaking changes reaching consumers without a new major version per quarter. Target: 0.
- Endpoints Behind a Gateway - Share of external and partner endpoints served through a managed gateway. Target: 100%.
- Scoped Agent Credentials - Share of MCP servers and agent clients using scoped, delegated credentials. Target: 100%.
- Sunsets on Date - Share of deprecated versions switched off by the published sunset date. Target: 90% or higher.
