How does the MCP layer cut agent cost?

Agents pull your conventions, docs, gaps, and verified commands directly over MCP instead of re-crawling the codebase on every prompt. One scoped lookup replaces dozens of exploratory file reads. That means fewer tokens, and fewer wrong guesses to redo in review.

Is the MCP server read-only?

Effectively, yes. The MCP layer is context-only and scoped per repository: it serves conventions, docs, and citations, and at most drafts doc updates for your agent to commit on its own branch. Never billing, settings, or the merge button.

Does it work with my agent?

Moxie exposes a standard Model Context Protocol server, so Claude Code, Cursor, Codex, and other MCP-aware tools can query repository context directly.

For staff & platform engineers

Stop being the codebase's human cache.

Architecture lives in your head; teammates and agents keep asking. Moxie turns that into source-cited docs and MCP context so the repo holds the answers.

The problem

Sound familiar?

Same questions every week

Where it lives, why it is built that way, what the convention is - only in your head and Slack.

Agents ignore conventions

They rediscover the repo each prompt and guess - you catch it in review.

Architecture docs go stale

The diagram is six refactors old; updating it is never the priority.

The fix

What you get

Architecture from source

Module maps and walkthroughs, cited to code, regenerated when code moves.

Conventions agents follow

MCP serves house rules and verified commands before the first edit.

Answers outside your DMs

One workspace for generated docs and Markdown - fewer interrupts.
