MCP (Model Context Protocol)MCP is an open standard for connecting an agent to external tools and data through a uniform interface, so a tool written once works with any compatible client. It turned the N-times-M integration problem into N-plus-M, and by 2026 shipping an MCP server is a routine part of a forward deployed engagement rather than a novelty.🤖 Retrieval & Agents🔒 Premium

REST API Design for IntegrationsThe API you hand a customer is the part of the deployment their engineers live with after you leave, so it is judged on how little it surprises them. Resources and verbs are the easy half; versioning, pagination, error shape and idempotency are what decide whether their integration keeps working next quarter.⚙️ System Design for AI in Production🔒 Premium

OAuth 2.0, JWTs and Service CredentialsOAuth 2.0 is delegated authorization: an app acts on a user's behalf without ever holding their password. Knowing which grant fits which caller, what a JWT does and does not prove, and how to act on behalf of a user from a backend is the difference between an integration that passes a security review and one that gets sent back.🛡️ AI Security, Privacy & Governance🔒 Premium

Agent-to-Agent Interoperability (A2A)MCP standardizes what an agent reaches downward, its tools. A2A standardizes what it reaches sideways, peer agents it neither owns nor can inspect. The second problem is harder because the peer is opaque by design, and it is the one an FDE meets first: the customer already has agents, and you do not get to redeploy theirs.🤖 Retrieval & Agents🔒 Premium

AG-UI: The Agent-User Interaction ProtocolAn agent's work is long-running and partial, so a request/response API cannot express it: the interface needs to show thinking, a tool call in flight, a half-written answer, and state that changed underneath. AG-UI standardizes that as one stream of typed events, which is what lets you ship an agent into a customer's own frontend instead of rebuilding a UI per deployment.🤖 Retrieval & Agents🔒 Premium
