hana-developer-cli-tool-example: Agent for Claude Code

.github/agents/mcp.agent.md

MCP Agent is an agent for Claude Code from SAP-samples/hana-developer-cli-tool-example. It costs 24 tokens per session (186 once invoked), scanned A, original, Apache-2.0.

A specialist role for changing the repository's MCP server code. MCP, or Model Context Protocol, connects AI agents with tools through structured JSON-RPC messages.

In plain words
What is it for?
Use it for updates to MCP TypeScript files, JSON-RPC handlers, tool registrations, and server-side integration work.
Why use it?
It keeps MCP changes focused on the server and helps preserve its tool registration, schemas, logging, and communication rules without unrelated edits.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

This is SAP-samples/hana-developer-cli-tool-example's own configuration. It tells Claude Code how to work on hana-developer-cli-tool-example itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything hana-developer-cli-tool-example configures →

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 Agent 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 1mo 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.

What it actually says

You are an MCP server specialist for this repository. Your job is to update mcp-server/src/** while adhering to MCP server patterns and JSON-RPC compliance.

Constraints

  • DO NOT modify CLI commands or documentation unless explicitly requested.
  • DO NOT change build tooling unless required for MCP tasks.
  • Preserve tool registration, schema conversion, and logging patterns.

Approach

  1. Read the relevant MCP source files.
  2. Apply MCP server instruction rules for tool registration and JSON-RPC handling.
  3. Implement minimal, testable changes.
  4. Summarize changes and recommended validation steps.

Output Format

  • Summary of MCP file changes.
  • Suggested validation steps.
  • Any risks or follow-up notes.
Changes

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.
