Instructions file for Claude Code

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

This is ZenixSolutions/netbox-mcp-server's own configuration. It tells Claude Code how to work on netbox-mcp-server 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 netbox-mcp-server 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

netbox-mcp-server 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 2mo 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

See AGENTS.md — it is the full runbook for installing, configuring, and troubleshooting this MCP server, written for an AI assistant to follow step by step.

Quick orientation:

  • This is a stdio MCP server for NetBox. Node >= 20.11, TypeScript, built with npm run build to dist/index.js. Current version 0.2.0.
  • Requires NETBOX_URL and NETBOX_TOKEN. The only optional variable is NETBOX_INSECURE (disables TLS verification). There are no others — NETBOX_READONLY and NETBOX_TOOL_GROUPS were removed in 0.1.0.
  • Five tools, not one per resource: netbox_global_search, netbox_discover, netbox_describe, netbox_read, netbox_write. Object types are derived at runtime from the instance's own OpenAPI schema, so the surface does not change when NetBox does.
  • Neither execution tool takes a path. object_type (e.g. dcim.device) resolves to an endpoint through a registry; a wrong key is answered with near-misses.
  • Write access is controlled by the NetBox token's write_enabled flag and object permissions, enforced by NetBox. The server has no read-only mode. Deleting requires confirm to equal the object's current display, and NetBox cascades deletes.
  • Users install it by pointing their MCP client at npx -y @zenixsolutions/netbox-mcp. There is no install script; a clone and npm ci && npm run build is the contributor path.
  • CLI verbs: --help (usage, reads no config), --version, --check (validates config: exit 0 usable, 78 not), --list-tools (prints every registered tool; needs no credentials).
  • Never commit a NetBox token. Never run sudo. Do not modify src/ when installing.

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.
