Cursor Coding Agent (MCP)

I have an mcp_servers.cursor bridge wired up to the Cursor TypeScript SDK. When the user asks for actual code work -- refactor a file, fix a bug, add a feature, audit a repo -- I do not write the code in my own message. I delegate to a Cursor agent via the cursor_agent MCP tool.

The Cursor agent is the same model that runs in the Cursor IDE: full file access, terminal, codebase semantic search, lints, iterative tool calls until tests pass. I am the orchestrator; Cursor is the implementer.

When to call cursor_agent

Yes:

• "Refactor src/utils.ts for readability"
• "Find the bug in apps/website/auth.ts and fix it"
• "Add a unit test for the new pricing function"
• "Walk this repo and write a one-line summary of every public function in lib/"
• "Migrate the tailwind.config.ts entries to Tailwind v4"

No:

• "What is dependency injection?" -- I answer directly, no Cursor needed.
• "What's in this MEMORY.md?" -- I read it myself.
• "Should I use Postgres or SQLite?" -- discussion, not code.

How to call it

cursor_agent(
    prompt="Refactor src/utils.ts: extract the date helpers into a separate module, keep public API identical, run pnpm typecheck after.",
    working_dir="/home/machine/work/my-repo",
    model="composer-2",
    load_skills=["agent-ethos", "git-workflow", "taste-output"],
)

load_skills is non-negotiable

Always pass load_skills. Pick the skills that match the task. The bridge writes the requested skills into <working_dir>/.cursor/rules/from-agent.mdc so the spawned agent inherits the same conventions the parent agent follows. Without load_skills, the Cursor agent reverts to its defaults -- which are excellent, but generic.

Default bundle for any code work:

• agent-ethos -- minimal-fix philosophy, hard limits
• taste-output -- no skeleton stubs, no // TODO placeholders
• empirical-verification -- verify claims, don't guess

Add as needed:

• git-workflow -- when the task involves commits/branches
• frontend-design-taste -- UI work
• security-audit -- auth, payments, secrets
• production-safety -- anything touching prod resources
• reticle-design-system -- UI work on a Reticle-based project
