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

.github/skills/mcp-server-workflows/SKILL.md

mcp-server-workflows is a skill for Claude Code from SAP-samples/hana-developer-cli-tool-example. It costs 31 tokens per session (267 once invoked), scanned A, original, Apache-2.0.

A set of instructions for developing MCP servers, which let coding agents expose tools through a standard protocol. It covers tool registration, JSON-RPC request handling, and related TypeScript code.

In plain words
What is it for?
Use it when adding or modifying MCP tools, JSON-RPC handlers, schemas, or utilities in an MCP server's source folder.
Why use it?
It gives developers a consistent way to change server tools and handlers while preserving argument schemas, logging, and protocol rules.

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-server-workflows 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

MCP Server Workflows Skill

Use this skill for MCP server updates, tool registration, and JSON-RPC handling.

When to Use

  • Adding or modifying tools in the MCP server
  • Adjusting JSON-RPC handlers or schemas
  • Updating MCP server utilities in mcp-server/src/

Procedure

  1. Identify the target MCP file(s) and tool/handler scope.
  2. Apply MCP server development instructions for JSON-RPC compliance.
  3. Ensure tool registration and schema conversion patterns are preserved.
  4. Make minimal, testable changes and keep logging consistent.
  5. Recommend validation steps (build or tests) as needed.

Notes

  • Keep tool naming and argument schemas aligned with CLI metadata.
  • Use structured logging (stderr) and avoid console.log for protocol data.

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.
