mcp-abap-adt: Instructions file for Claude Code

CLAUDE.md

mcp-abap-adt CLAUDE.md is an instructions file for Claude Code from fr0ster/mcp-abap-adt. It costs 6,004 tokens per session, scanned A, original, Apache-2.0.

Development and testing guidance for an MCP server that connects to SAP systems through ABAP Development Tools. It explains two integration-test modes: one that calls handlers directly and one that runs the full server.

In plain words
What is it for?
Use it when developing or testing the MCP ABAP ADT integration, setting up shared SAP objects, checking the SAP environment, or reviewing long-running integration-test results.
Why use it?
It helps agents choose the right test approach, preserve complete logs, and handle shared SAP test objects without making unsafe assumptions about the user's system.

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-abap-adt 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 5d 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.

MCP ABAP ADT - Development Guide

Testing

Integration Tests

Integration tests run against a real SAP system. Two modes:

  • Soft mode (default, integration_hard_mode.enabled: false): calls handlers directly, no MCP subprocess.
  • Hard mode (integration_hard_mode.enabled: true): spawns full MCP server via stdio, calls tools through MCP protocol.

Strategy: Run soft mode for mass regression testing. Use hard mode only for targeted verification of recent changes.

Shared objects: Before the first test run, create shared SAP objects (tables, CDS views, service definitions, classes) that some tests depend on:

npm run shared:setup     # first run only, persists across test runs
npm run shared:check     # verify they exist

Important: Shared object setup and SAP environment verification require collaboration with the user. Don't try to automate everything — run shared:setup once, show the result, and ask the user to verify activation in ADT. If activation fails, ask the user what they see rather than retrying blindly.

Running integration tests: Always save full output to a log file — do NOT truncate with tail. Tests take 15-25 minutes; use timeout 1800 (30 min) or run_in_background with no timeout truncation. This avoids re-running long tests just to see errors.

# Soft mode (mass run) — save full log
npm run test:integration 2>&1 | tee /tmp/integration-test.log

# Hard mode (targeted, in test-config.yaml set integration_hard_mode.enabled: true)
npm test -- --testPathPatterns=<specific-test>

Test Configuration

All test parameters live in tests/test-config.yaml (gitignored). The template (tests/test-config.yaml.template) works out of the box with sensible defaults.

Setup:

cp tests/test-config.yaml.template tests/test-config.yaml
# Edit ONLY the lines marked "# ← CHANGE"

Required changes (marked # ← CHANGE):

  • environment.env — session .env file name ("your-system.env", "another-system.env") from standard sessions folder
  • environment.system_type — "onprem", "cloud", or "legacy"
  • environment.connection_type — "http" (default) or "rfc"
  • environment.default_package — dev package (ZMCP_TEST, $TMP)
  • environment.default_transport — transport request or "" for local packages
  • shared_dependencies.package — package for shared test objects
  • shared_dependencies.software_component — "LOCAL", "HOME", etc.

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.
