Practical lesson
Examples Model Context Protocol (MCP)
See where the skill appears in realistic work situations and what strong execution looks like.
The idea in one minute
Model Context Protocol skill means understanding both the protocol and the integration discipline around it. MCP standardizes how AI applications discover and invoke capabilities exposed by servers. A competent practitioner can model useful tools and resources, define schemas, build clients or servers with official SDKs, handle transport and authorization correctly, validate inputs and outputs, constrain permissions, test failure modes, observe calls and manage protocol upgrades. MCP is not permissionless model access to everything: production implementations require deliberate identity, authorization, least privilege, consent and trust boundaries. The July 2026 specification materially changed the protocol toward a stateless HTTP-native core, so current competence also requires version awareness rather than relying on older session-oriented tutorials.
This capability connects directly with API Development, AI Security, Agentic AI. Open those concepts when the lesson depends on them rather than treating Model Context Protocol (MCP) as an isolated ability.
Real-world situations
- 1.Exposing read-only CRM search as a narrowly scoped MCP tool instead of giving an agent broad database credentials
- 2.Migrating a server from older session-oriented MCP assumptions to the 2026-07-28 stateless protocol
- 3.Separating a draft-email tool from a send-email tool so consequential action requires stronger authorization
- 4.Routing and auditing MCP calls through an enterprise gateway using method and tool metadata
What strong execution looks like
- 1.A strong practitioner begins with the minimum capability an AI application actually needs. They design explicit tool names and schemas, validate all inputs, return structured errors, isolate credentials, scope authorization, distinguish read from write operations, require additional controls for consequential actions, test malicious and malformed inputs, log enough for investigation, and pin/test protocol versions. They understand the host-server trust boundary and do not confuse protocol interoperability with authorization.
- 2.Software and AI engineers build servers and clients; platform teams manage registries and gateways; security engineers design authorization and policy; product teams define safe tool semantics; enterprise architects standardize integrations.
