codeql-development-mcp-server: Skill for Claude Code

.github/skills/validate-ql-mcp-server-tools-queries/SKILL.md

validate-ql-mcp-server-tools-queries is a skill for Claude Code, Codex from advanced-security/codeql-development-mcp-server. It costs 71 tokens per session (3,028 once invoked), scanned A, original, no licence file.

A procedure for checking that the CodeQL Development MCP Server’s bundled queries return abstract syntax tree, control-flow graph, and call-graph data. These are different views of source code structure and execution.

In plain words
What is it for?
Use it to validate AST, CFG, and call-graph results from the server’s query-running tool for supported languages.
Why use it?
It detects when the server runs but fails to return the analysis data its tools are expected to provide.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing.

This is advanced-security/codeql-development-mcp-server's own configuration. It tells Claude Code and Codex how to work on codeql-development-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything codeql-development-mcp-server configures →

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

validate-ql-mcp-server-tools-queries 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 1mo 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
