What is HAbedini-qspice-mcp AGENTS.md?

A setup guide for connecting the QSpice MCP server to Cursor or Visual Studio Code on Windows. MCP is a way for an editor or agent to connect to an external tool or service.

Use it to install and configure the QSpice connection, select Cursor or VS Code, choose the workspace and executable, restart the editor, and run a connection check.

It explains where the connection is registered, how to merge it with existing settings, and how to verify that the editor can reach QSpice.

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	$0.01361	$0.01361
Opus 5	$0.00681	$0.00681

Security

Grade A, and why

HAbedini-qspice-mcp 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 10d 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.

Agent guide — first-time MCP setup (Windows)

Use this file when the user asks to install, configure, or connect the QSpice MCP server in Cursor or VS Code after cloning this repo.

MCP is registered at user level (available in every project). The setup script merges a qspice entry into existing configs without removing other servers.

Client	User config path (Windows)
Cursor	`%USERPROFILE%\.cursor\mcp.json`
VS Code	`%APPDATA%\Code\User\mcp.json`

Quick setup (preferred)

From the cloned repo root in PowerShell:

pwsh -ExecutionPolicy Bypass -File .\scripts\setup_mcp.ps1 -WorkspaceRoot "D:\path\to\your\circuit\folder"

Omit -WorkspaceRoot → defaults to %USERPROFILE%\Desktop\qspice-mcp-test
Omit -QspiceExe → auto-detect QSPICE64.exe
-Clients Cursor | VSCode | Both (default: Both)

Then tell the user:

Fully restart Cursor or VS Code (reload is often not enough after first MCP install).
Open Settings → Tools & MCP and confirm qspice is connected.
Optional: pwsh -ExecutionPolicy Bypass -File .\scripts\verify_mcp.ps1

Smoke prompt:

Call describe_server_capabilities on the qspice MCP server and summarize tool groups.

What the setup script does

Creates .venv in the cloned repo and runs pip install -e .
Detects QSPICE64.exe (or uses -QspiceExe)
Merges qspice into user-level MCP JSON (absolute paths; preserves other servers)
Runs python -m qspice_mcp --describe as a sanity check

Important: The venv stays in the repo you cloned; user-level MCP points at that venv with absolute paths. Re-run setup after moving the repo.

Simulation workspace (--workspace-root) is where .qsch files live — independent of which IDE folder is open.

Agent checklist

Step	Action
1	Confirm Windows + Python ≥ 3.11 on PATH
2	Run `scripts/setup_mcp.ps1` with user's circuit folder as `-WorkspaceRoot`
3	On failure: install QSpice, pass `-QspiceExe`, or recreate repo `.venv`
4	Ask user to fully restart IDE
5	Call `describe_server_capabilities` via MCP

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.
