CCA-F: Claude Certified Architect — Foundations

You are creating developer-productivity tools with the Claude Agent SDK. The agent assists engineers in exploring unfamiliar codebases, understanding legacy systems, generating boilerplate code, and automating repetitive work. It uses the built-in tools (Read, Write, Bash, Grep, Glob) and integrates with Model Context Protocol (MCP) servers.

Your productivity agent connects to three MCP servers: an issue tracker (search_issues, get_issue, create_comment), a documentation wiki (search_docs, get_page, list_spaces), and a database explorer (run_query, get_schema, list_databases). When engineers ask cross-system questions such as “What database tables are affected by the authentication refactor in PROJ-1234?”, monitoring shows that the agent makes 8-10 sequential tool calls, often makes exploratory calls because it has no visibility into the content each server contains, and uses up context space before completing complex investigations.

Which architectural change most effectively leverages MCP capabilities to resolve these issues?
