What is RenderdocMCP CLAUDE.md?

A set of Claude Code instructions for an MCP server that connects an AI assistant to RenderDoc. RenderDoc is a tool for inspecting captured graphics from applications such as games.

Listing and opening graphics captures, checking their loading state, and filtering draw calls during DirectX 11 or 12 debugging.

It documents how the server, its RenderDoc extension, and their file-based connection fit together.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01504	$0.01504
Opus 5.5	$0.00602	$0.00602
Sonnet 5.5	$0.00301	$0.00301
Haiku 4.5	$0.00150	$0.00150

Security

Grade A, and why

RenderdocMCP 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.

Origin

This is a copy

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.
