Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

domain-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

CLAUDE.md

This is a pnpm workspace monorepo. Two packages live under packages/:

  • packages/domain-mcp/ — the domain-mcp npm package: a stdio MCP server wrapping the Dynadot registrar API. See packages/domain-mcp/CLAUDE.md for architecture, commands, and conventions.
  • packages/domain-agent-kit/ — the portable Agent Plugins v1 workflow package built on domain-mcp. Canonical behavior lives in skills/domain-management/; the Claude manifest, MCP declaration, and destructive-operation hook are thin compatibility adapters.

When editing code

  • Changes to the MCP server: work inside packages/domain-mcp/. Use pnpm --filter domain-mcp run <script> or cd packages/domain-mcp && pnpm <script>.
  • Changes to the plugin: work inside packages/domain-agent-kit/. Run pnpm --filter domain-agent-kit test and hermes plugins doctor packages/domain-agent-kit --ci after changes.

Root commands

pnpm install       # install all workspace deps
pnpm build         # build domain-mcp
pnpm test          # test domain-mcp
pnpm typecheck     # tsc --noEmit domain-mcp
pnpm check         # biome across repo
pnpm check:fix     # biome --write across repo

Publishing

Only packages/domain-mcp/ publishes to npm. Tag pushes on main trigger the publish job in .github/workflows/ci.yml. The plugin publishes via the Claude Code marketplace (manifest at .claude-plugin/marketplace.json).

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
