Build defensible controls for MCP servers and tool-using agents, from authorization and isolation to monitoring
Map clients, agents, servers, hosts, and upstream APIs to determine where authorization, validation, and isolation controls belong.
Identify misleading descriptions and schemas that can steer agents toward unsafe actions or data disclosure.
Implement MCP-compatible authorization with discovery, PKCE, minimized scopes, audience validation, and separated credentials.
Design tool permissions and argument constraints that support necessary work without broad access or unsafe parameters.
Evaluate provenance, pin server versions, maintain inventories, and define telemetry for detecting drift, abuse, and control failures.
Apply an end-to-end rollout pattern that connects threat modeling, controls, evidence, and ongoing monitoring for a development team.

Define how MCP changes the AI tool threat model and map trust boundaries across clients, agents, servers, hosts, and upstream APIs.
2 lessonsAnalyze poisoned metadata, silent server changes, and confused-deputy conditions that can steer agents toward unsafe actions or unauthorized disclosure.
3 lessonsImplement OAuth and token separation, then constrain tools and arguments with least-privilege permissions that limit unnecessary access.
3 lessonsApply local sandboxing, server vetting, version pinning, inventory, and tool-call monitoring within a secure development-team rollout pattern.
4 lessonsMCP changes the security model for AI tools by connecting agents to servers, hosts, and upstream APIs across trust boundaries. This course helps intermediate developers and platform engineers analyze those risks and build practical defenses around authorization, token handling, least privilege, sandboxing, server integrity, and monitoring. You will leave with a framework for securing an MCP setup and retaining evidence for triage, audits, and incident response.
The course covers MCP trust boundaries, tool poisoning, malicious updates, confused-deputy attacks, OAuth authorization, token validation, least-privilege controls, sandboxing, server supply-chain practices, tool-call telemetry, and team rollout patterns.
From project managers and operators to founders, analysts, and teams adopting AI, Fenzo is for people who want to get better at the work they already do.
Anything from using AI for project planning and analysis to improving workflows, decision-making, communication, and delivery. If you can describe the skill or task, Fenzo can build a course around it.
Yes. Tell Fenzo what you do, what you’re trying to accomplish, and where you’re stuck, and Fenzo will shape the course around your role, your goals, and the work you actually have to do.
No. Fenzo adapts to your starting point, so you can begin with the fundamentals or jump straight into more advanced work.
Yes. Fenzo for Business puts the whole team on one plan — shared seats, courses you can assign, and reporting on who has finished what.
See Fenzo for BusinessYou start by describing your goal or taking a short skill benchmark. Fenzo uses that context to identify gaps and shape the learning experience around them.

Something to operate in every section.
Three findings from decades of learning research shaped how every Fenzo lesson is built.

What the science says
Students in lecture-only classes are 1.5× more likely to fail.
How Fenzo does it
Every Fenzo lesson is interactive. No passive reading or watching, ever.

Skill retention over time · with vs. without practice
What the science says
Offloading thinking to AI erodes the very skills you’re trying to build.
How Fenzo does it
Fenzo makes you do the thinking — guided, but never done for you.

Long-term recall · retrieval vs. re-reading
What the science says
Recalling information beats re-reading it for building durable understanding.
