Coding agents get stronger when they are paired with browser control, memory, eval, and MCP surfaces. A good coding agent alone is not enough. The highest-leverage stack usually combines one coding agent with a browser layer, a retrieval/context layer, and a tool bridge.
browser
Use browser automation and inspection tools when the coding loop must debug real UI state, network flows, or auth paths.
memory
Persistent memory and context layers matter once coding work spans multiple sessions, repos, or operators.
eval
Use evals and regression gates to catch fake improvements that only look good on easy tasks.
MCP
MCP servers turn a coding agent into an operator surface by exposing browsers, infra, docs, databases, and internal workflows.
