What is RenderDocMCP CLAUDE.md?

Project instructions for RenderDocMCP, a server that lets an AI assistant inspect RenderDoc graphics captures. RenderDoc is a tool for debugging rendered graphics such as DirectX 11 and 12 frames.

Use it to list and open capture files, check their loading status, and retrieve filtered drawing-call information while debugging graphics.

It documents how the server, RenderDoc extension, and file-based communication fit together, so agents can use the project consistently.

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.
