rpc

A command for examining RPC interfaces in Windows binaries. RPC, or remote procedure call, lets software request functions from another process or computer.

In plain words
What is it for?
List RPC interfaces and endpoints, rank the attack surface, audit security, trace handler data flow, and analyse client-server relationships.
Why use it?
It maps how these interfaces work and highlights security properties and possible attack paths that are difficult to inspect manually.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

rpc 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 3d 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.

RPC Analysis

Overview

Analyze RPC interfaces in Windows binaries using ground-truth NtApiDotNet extraction data. Enumerates interfaces, maps the RPC attack surface, audits security properties, and traces handler call chains.

The text after /rpc is the module name and optional subcommand (e.g., /rpc appinfo.dll, /rpc surface, /rpc audit appinfo.dll).

Subcommands

Subcommand Usage Purpose
(default) /rpc <module> Enumerate all RPC interfaces, procedures, endpoints
workspace /rpc workspace Discover which workspace modules implement RPC interfaces
surface /rpc surface [module] Risk-ranked RPC attack surface (module or system-wide)
audit /rpc audit <module> RPC-specific security audit
trace /rpc trace <module> <function> Trace RPC handler data flow to sinks
clients /rpc clients <uuid> Find modules implementing/consuming a UUID
topology /rpc topology [module] System-wide or per-module RPC client-server topology
blast-radius /rpc blast-radius <module or uuid> Show co-hosted interface impact analysis
stubs /rpc stubs <uuid> Show C# stub parameter signatures for an interface

IMPORTANT: Execution Model

This is an execute-immediately command. Do NOT present anything for user confirmation. Run the requested analysis and present the report directly.

Execution Context

IMPORTANT: Skill script invocations like python .claude/skills/.../script.py can be run from the workspace root because those scripts manage their own path setup.

Steps

Step 0: Preflight Validation

Parse the subcommand and arguments:

  • No subcommand + module name -> enumerate interfaces (default)
  • surface + optional module -> attack surface ranking
  • audit + module -> security audit (requires DB path)
  • trace + module + function -> handler chain trace (requires DB path)
  • clients + UUID -> find modules for interface
  • topology + optional module -> RPC client-server topology (system-wide or per-module)
  • blast-radius + module or UUID -> co-hosted interface impact analysis
  • stubs + UUID -> C# stub parameter signatures for interface

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.

rpc is a command published in the GitHub repository marcosd4h/DeepExtractRuntime (20 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,848 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
