MCP_SAP: Instructions file for Claude Code

CLAUDE.md

MCP_SAP CLAUDE.md is an instructions file for Claude Code from sangvucitek/MCP_SAP. It costs 1,988 tokens per session, scanned A, original, MIT.

A project instruction file for Claude Code, an AI coding assistant, describing the SAP development project, its current priorities, and how to build and test it.

In plain words
What is it for?
Keeping work aligned on the graph engine, GUI debugger, open issues, and Go build and test tasks.
Why use it?
It gives the assistant the project context it needs instead of making it rediscover goals, structure, and commands in every session.

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

MCP_SAP 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

vsp — Go-native MCP server and CLI for SAP ABAP Development Tools (ADT).

Doc intent: CLAUDE.md = dev context. README.md = user onboarding. reports/ = research/history. contexts/ = session handoff.


Current Priorities

1. Graph Engine (pkg/graph/) — In Progress

Sequence: unify existing dep logic → SQL/ADT adapters → impact/path queries.

  • Done: core types, parser dep extraction, boundary analyzer (11 tests)
  • Pending: SQL adapters (CROSS/WBCROSSGT/D010INC), ADT adapters, unify cli_deps.go + cli_extra.go + ctxcomp/analyzer.go
  • Design: 002, 003

2. GUI Debugger (Issue #2) — Strategic

Plan: MCP debug sessions → DAP → Web UI. ADT REST API mapped from CL_TPDA_ADT_RES_APP. Design: 001

3. Open Issues

  • #88 Lock handle bug (EditSource/WriteSource) — real user report
  • #55 RunReport in APC — architectural limit
  • #46, #45 Sync script — low effort

Build & Test

go build -o vsp ./cmd/vsp              # Build
go test ./...                           # Unit tests
go test -tags=integration -v ./pkg/adt/ # Integration (needs SAP)
make build-all                          # 9 platforms

Key flags: --mode focused|expert|hyperfocused, --read-only, --allowed-packages "Z*", --disabled-groups 5THD


Codebase

internal/mcp/
  handlers_*.go       Domain handlers (read, edit, debug, graph, ...)
  tools_register.go   Registration + mode logic
  tools_focused.go    Focused mode whitelist
  handlers_universal.go  Hyperfocused single-tool (SAP)
pkg/
  adt/                ADT client (HTTP, CSRF, sessions, all SAP ops)

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.
