What is firewalla-mcp-server CLAUDE.md?

Repository instructions for building an MCP server that gives Claude access to Firewalla firewall data. Firewalla is a network security device and service; MCP is a way for an AI assistant to call external tools.

Use them when developing or changing the server’s 28 tools for firewall alarms, network flows, and other Firewalla resources.

They prevent API work based on made-up endpoints and require developers to follow the documented Firewalla API and routing rules.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.

Model	Per session	Once invoked
Fable 5	$0.03288	$0.03288
Opus 5	$0.01644	$0.01644
Sonnet 5	$0.00658	$0.00658
Haiku 4.5	$0.00329	$0.00329

Security

Grade A, and why

firewalla-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 5d 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

CRITICAL: Before Any API Development

READ FIRST: /docs/firewalla-api-reference.md - Complete Firewalla API specification

Key Rules:

ONLY use endpoints documented in /docs/firewalla-api-reference.md
NEVER assume endpoints exist without verification
ALWAYS use box-specific routing: /v2/boxes/{box_gid}/{resource}
NEVER use fictional endpoints like /stats/simple or /trends/flows
ALWAYS implement client-side aggregation for bandwidth/trends

Project Overview

A Model Context Protocol (MCP) server that provides Claude with access to Firewalla firewall data. Features a 28-tool architecture with advanced search capabilities.

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.
