What is mist-mcp-server AGENTS.md?

A project instruction file for an AI agent working on a server that connects to Juniper Mist, a network-management service. It defines the project’s mission, users, engineering rules, tools, and setup choices.

Guiding agents that develop or maintain the Juniper Mist MCP server, including its Python setup, testing, formatting, and configuration.

It gives an AI agent shared rules and project context before it changes code. This reduces the risk of inconsistent implementation or unsafe API work.

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 5.1	$0.00906	$0.00906
Opus 5.5	$0.00362	$0.00362
Sonnet 5.5	$0.00181	$0.00181

Security

Grade A, and why

mist-mcp-server 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 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.

Mission

Deliver a production-grade MCP server that wraps Juniper Mist API via mistapi, optimized for simple local use in Cursor/VS Code/Claude Desktop and extensible by the wifi ecosystem.

Intended Users

Non-technical operators using Cursor or VS Code to query Mist.
Network engineers and operators who want safe, guided API access.
Developers extending tools or automations for the Mist ecosystem.

Engineering Principles (Enforced)

DRY, KISS, YAGNI.
Separation of Concerns and composition over inheritance.
Favor functional patterns, immutability, and pure functions where practical.
Apply SOLID for non-trivial design.
Test-driven mindset where feasible.

Technical Decisions (Current-Year, Production-Grade)

Language: Python 3.10+.
MCP framework: mcp with FastMCP using stdio transport.
Mist API SDK: mistapi (direct wrapper; no custom HTTP layer).
Configuration: environment variables, loaded from .env when present.
Packaging: pyproject.toml with editable installs; no custom bootstrap scripts.
Lint/format: ruff (lint + format).
Types: mypy (strict).
Tests: pytest + pytest-cov.
Security tooling: pip-audit for dependency vulns.
Code quality platform: Snyk or SonarQube if CI is added; prefer Snyk for OSS.

All decisions are default choices unless a change request documents why.

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.
