mcp-devops-on-prem: Instructions file for Claude Code

CLAUDE.md

mcp-devops-on-prem CLAUDE.md is an instructions file for Claude Code from zwitbaum/mcp-devops-on-prem. It costs 1,276 tokens per session, scanned A, original, Apache-2.0.

Instructions for connecting a coding agent to an on-premises Azure DevOps Server or older Team Foundation Server installation through an MCP server. They document the Python service, connection settings, and supported tool groups.

In plain words
What is it for?
Setting up the local service, choosing its transport, configuring NTLM, personal access token, or bearer-token authentication, and finding the main code and command-line entry points.
Why use it?
They give the agent the project context needed to recommend and inspect the service correctly. They also clarify which server address and one of the supported authentication methods must be configured.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is zwitbaum/mcp-devops-on-prem's own configuration. It tells Claude Code how to work on mcp-devops-on-prem 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 mcp-devops-on-prem 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-devops-on-prem 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 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 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.
