explain-mdx is a skill for Claude Code, Codex from tghanchidnx/mdx-mcp. It costs 31 tokens per session (209 once invoked), scanned A, original, Apache-2.0.

A plain-language explainer for MDX queries, which are instructions for retrieving selected business data from an OLAP cube.

In plain words
What is it for?
Use it to explain which measure is returned, what filters or context are applied, and what single value the query produces.
Why use it?
It helps people understand what an existing or generated query asks for without reading query syntax. It also connects the query to the business question it answers.

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

explain-mdx 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

explain-mdx

Teach what an MDX query means, using mdx-mcp.

Steps

  1. Take the MDX (from a prior mdx_ask result's mdx, or one the user pastes).
  2. Call mdx_explain(mdx=<the query>).
  3. Relay the explanation, and connect it back to the business question: which measure is returned, what slice/context (WHERE) constrains it, and what single value results.
  4. If the user wants to run it, use mdx_run(mdx=<the query>) (read-only).

Guardrails

  • Don't claim the query is "correct" — explain what it does; correctness is what mdx_ask's verification is for.
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.
