The Model Context Protocol is Anthropic's open standard reshaping how LLMs connect to tools and data. If you're interviewing for Claude ecosystem roles or AI platform engineering, expect MCP questions. Understand host vs server architecture and how MCP differs from ad-hoc function calling.
Read full explanationMCP (Model Context Protocol) defines a clean separation:
Read full explanationMCP multiplies agent power and attack surface.
Read full explanationMedium MCP product/security question on consent UX for side-effecting tools.
Read full explanationCompany-based MCP questions assess platform leadership, not wire protocols alone.
Read full explanationDangerous tools are why agents aren't auto-root on production.
Read full explanationRate limiting for agents differs from human API usage — bursts are larger and less predictable.
Read full explanationMigration questions test program management as much as protocol knowledge.
Read full explanationMCP testing maturity separates hobby servers from production integrations.
Read full explanationDeployment topology shapes MCP architecture — interviewers test practical product sense.
Read full explanationMCP supply-chain interviews mirror DevSecOps — because installing a server is installing code with tool access.
Read full explanationAgents waste tokens and cause incidents when errors are opaque strings.
Read full explanationLong-running tools expose gaps between synchronous tool calling and real workloads.
Read full explanationDatabase MCP is high risk/high value — interviewers probe your safety instincts hard.
Read full explanationSandboxing interviews connect MCP to supply-chain security (mcp-014) and auth (mcp-004).
Read full explanationMulti-server hosts are production reality — GitHub + Jira + DB + docs + internal APIs. Poor design creates tool soup.
Read full explanationThis question tests integration strategy, not religious protocol loyalty.
Read full explanationAgents fail opaquely without MCP observability. Treat every tool call as a microservice span.
Read full explanationTool schema drift breaks agents silently — models call old argument shapes and get 400s. Interviewers want a semver-minded process.
Read full explanationEnterprise MCP rarely connects laptops directly to SaaS MCP servers. The gateway is the control plane interviewers want you to design.
Read full explanationMCP auth interviews test whether you treat agents as privileged automation — because they are.
Read full explanationBuilding a custom MCP server is a common system-design follow-up to "what is MCP?" Strong candidates describe end-to-end architecture, not just SDK boilerplate.
Read full explanationMCP exposes three complementary primitives that interviewers use to test whether you understand protocol design, not just buzzwords.
