CiscoFMC-MCP-server-community AGENTS.md

CiscoFMC-MCP-server-community AGENTS.md is an instructions file for Codex, OpenCode from CiscoDevNet/CiscoFMC-MCP-server-community. It costs 303 tokens per session, scanned A, original, MIT.

Repository rules for an MCP server that safely queries Cisco Secure Firewall Management Center, a system used to manage firewall policies and rules. They require input validation, limited API access, safe pagination, and removal of sensitive credentials from results.

In plain words
What is it for?
Use them when adding or changing read-only firewall policy queries, validating IPs or domains, handling pagination, running tests, or preparing a pull request.
Why use it?
They prevent accidental exposure of credentials and reduce the chance that queries accept unsafe indicators or request more data than necessary.

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

CiscoFMC-MCP-server-community AGENTS.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.

What it actually says

AGENTS.md

This repo is a Model Context Protocol (MCP) server that connects to Cisco Secure Firewall Management Center (FMC) and exposes safe, high-level tools for querying policies/rules.

Non-negotiable guardrails

  • Never add code that logs, prints, or returns FMC credentials/tokens.
  • Never weaken input validation for indicators (IP/CIDR/range/FQDN/identity indicators).
  • Any new tool must enforce: validation -> least-privilege API calls -> bounded pagination -> redaction.
  • Do not introduce “execute/change” capabilities unless explicitly requested (this project is primarily read/query).

Setup commands

  • Create venv: python -m venv .venv && source .venv/bin/activate
  • Install deps: pip install -r requirements.txt
  • Run tests: python -m pytest tests
  • Run server (local): python -m sfw_mcp_fmc.server
  • Run server (docker): docker compose up -d --build

Code style & quality

  • Prefer small modules, SOLID boundaries, and explicit error handling.
  • Add/extend unit tests for parsing + search logic.
  • Do not add heavy dependencies unless necessary.
  • Keep API calls time-bounded and handle FMC pagination safely.

Security checks before PR

  • Ensure .env is NOT committed.
  • Ensure logs don’t include secrets.
  • Ensure any new endpoint/tool has input validation + output redaction.
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.
