Use it to locate the function in engine2.dll or libengine2.so on supported game builds.

It provides a recovery path when the normal preprocessor script fails or the binary's call structure has changed.

find-INetworkServerService_GetServerSerializersCRC

Q: What is find-INetworkServerService_GetServerSerializersCRC?

An IDA Pro MCP fallback workflow for finding the GetServerSerializersCRC virtual function in Counter-Strike 2 engine binaries. It starts from a known related function and checks reference YAML data.

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	$0.00158	$0.01187
Opus 5.5	$0.00063	$0.00475

Security

Grade A, and why

find-INetworkServerService_GetServerSerializersCRC 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 14d 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.

Find INetworkServerService_GetServerSerializersCRC (final-guarantee fallback)

Recover the virtual function INetworkServerService::GetServerSerializersMsg in CS2 engine2.dll / libengine2.so using IDA Pro MCP tools. This is the Agent fallback for the find-INetworkServerService_GetServerSerializersCRC skill: it runs only when the preprocessor script returned failure (almost always a transient LLM error, or the predecessor's call structure moved).

Realworld Function References

Read the platform-relevant reference YAMLs before searching in IDA. They contain the annotated virtual call site (; 0x148/0x150 = ... = INetworkServerService_GetServerSerializersCRC). Treat their addresses as reference-build values only; verify against the current binary.

Windows baseline: ida_preprocessor_scripts/references/engine/CNetworkGameServer_WriteClassInfosAndSerializesToBuffer.windows.yaml
Linux baseline: ida_preprocessor_scripts/references/engine/CNetworkGameServer_WriteClassInfosAndSerializesToBuffer.linux.yaml

Step 1. Load and decompile the predecessor

ALWAYS Use SKILL /get-func-from-yaml with func_name=CNetworkGameServer_WriteClassInfosAndSerializesToBuffer to obtain its func_va. If it returns an error, STOP and report to user (this fallback cannot run without the predecessor).

Decompile it:

mcp__ida-pro-mcp__decompile addr="<CNetworkGameServer_WriteClassInfosAndSerializesToBuffer.func_va>"

Step 2. Locate the virtual call to the target

INetworkServerService::GetServerSerializersMsg(this) is an indirect virtual call on the global g_pNetworkServerService. Anchor by its semantic fingerprint, not a fixed offset:

It is the first call qword ptr [reg + <off>] where reg = *g_pNetworkServerService (load the vtable from the global, then call through it), near the top of the function.
It takes no extra argument and returns a serializers-message pointer whose contents are written into the class-info/serializer buffer. Do not confuse it with the adjacent CRC-computation method. Legacy annotations call this pointer accessor GetServerSerializersCRC; that label is an artifact key, not its semantics.
