ops-agent-toolkit-mcp: Instructions file for Claude Code

CLAUDE.md

ops-agent-toolkit-mcp CLAUDE.md is an instructions file for Claude Code from Jeromefromcn/ops-agent-toolkit-mcp. It costs 362 tokens per session, scanned A, original, MIT.

Instructions for a read-only operations MCP server used by an agent troubleshooting a sandbox. It exposes logs, measurements, traces, and service or configuration details from a lab environment.

In plain words
What is it for?
Use it to inspect logs, metrics, traces, service discovery, and configuration while diagnosing issues across the connected lab repositories.
Why use it?
It helps an agent investigate system problems while keeping operations limited to inspection and ensuring tool calls are audited.

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is Jeromefromcn/ops-agent-toolkit-mcp's own configuration. It tells Claude Code how to work on ops-agent-toolkit-mcp 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 ops-agent-toolkit-mcp 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

ops-agent-toolkit-mcp 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.

What it actually says

CLAUDE.md

Keep any additions to this file short and direct.

Project

MCP server exposing read-only ops tools (logs, metrics, traces, service discovery/config) to an agent troubleshooting the sandbox in lab-environment.

Cross-repo contract

This repo, lab-environment, and spring-petclinic-microservices don't share Claude Code session context — a session working here has no memory of what the other two assume. Before touching Consul KV paths, DB names, service names, or chaos toggle names, read lab-environment/CLAUDE.md's "Cross-repo contract" table — that file is the single source of truth, not this one.

Key commands

  • python server.py — run locally in stdio mode
  • docker build -t ops-lab/mcp-toolkit:dev . — build the container image (HTTP/SSE mode, joins the lab-environment compose network)

Conventions

  • One tool = one responsibility. A tool must not silently do more than its name implies.
  • Never expose a raw query language (PromQL, LogQL) directly to the model — wrap it in a parameterized function.
  • Every tool call goes through the @audited decorator. No exceptions.
  • Tool outputs are summarized/formatted for the model, not raw JSON dumps.
  • Read-only, except toggle_chaos_scenario (scoped to config/<service>/data/chaos.* keys only). No tool restarts services, rolls back deployments, or writes real app config. Do not add further write-capable tools without discussing first.

Roadmap

See ROADMAP.md for planned tool additions by phase.

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.
