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 B, and why

setting-up-coredash scanned grade B with 1 finding 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 8d 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.

Setting Up CoreDash

Invocation

Called by the cwv-superpower orchestrator when CoreDash is unavailable and the user wants to connect, or invoked directly when the user asks how to set up CoreDash MCP.

Do not skip steps. Walk the user through each step and wait for confirmation before moving to the next.


Step 1: Detect the MCP client

Ask the user which tool they are working in:

"Which AI coding tool are you using?"

  • Claude Desktop
  • Claude Code (terminal)
  • Cursor
  • Windsurf
  • Gemini CLI
  • Other

Store the answer for Step 4.


Step 2: Check for a CoreDash account

Ask the user:

"Do you have a CoreDash account at app.coredash.app?"

  • If yes: proceed to Step 3.
  • If no: say the following and wait:

"You'll need a free CoreDash account first. Go to https://coredash.app/signup and create one. It takes about two minutes. Come back here when you're in."


Step 3: Choose a connection method

CoreDash MCP accepts two authentication methods. Pick based on the client and use case:

Method Best for API key needed?
Browser login (OAuth) Interactive use in native/CLI clients like Claude Code (terminal) No
API key (cdk_…) Headless / automated / CI, agency or multi-project setups (master keys), and config-file clients (Claude Desktop, Cursor, Windsurf, Gemini CLI) Yes

Both connect to the same hosted server — nothing changes on the CoreDash side. OAuth is the better experience for interactive clients; API keys are the right choice when there's no interactive browser.

  • If the user is on Claude Code (terminal) and wants the simplest path → use Option A (Browser login) in Step 4.
  • For headless/CI use, multi-project agency setups, or any config-file client → use Option B (API key) in Step 4.

Step 4: Connect

Option A — Browser login (OAuth), recommended for Claude Code

No API key required. Add the server with no header:

claude mcp add --transport http coredash https://app.coredash.app/api/mcp

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.
