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

notepadpp-mcp 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 1mo 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.

Notepad++ MCP — Agent skill

Description: Automate Notepad++ on Windows via pywin32 MCP bridge. Covers file operations, macro automation, session management, plugin control, text manipulation, syntax linting, and display configuration.

Trigger Phrases

  • "Open [file] in Notepad++"
  • "Save the current tab"
  • "Replace all [pattern] with [replacement]"
  • "Run Python linter on current file"
  • "Install the JSON plugin"
  • "Close all tabs and start fresh"
  • "Find [text] in the current document"
  • "Record a macro to [action]"

Tools (Portmanteau Pattern)

  • file_ops(operation, file_path) — Open, save, close, new files. Operations: open, save, save_as, close, new, info.
  • text_ops(operation, text, ...) — Text manipulation. Operations: insert, replace, find, select_all, get_text, get_length.
  • tab_ops(operation, ...) — Tab/buffer management. Operations: list, switch, close, close_all, activate_by_index.
  • session_ops(operation, ...) — Session save/load. Operations: save_session, load_session, list_sessions.
  • linting_ops(operation, file_path) — Run linters. Operations: python, javascript, html, xml, json, custom.
  • display_ops(operation, ...) — UI display. Operations: word_wrap, show_whitespace, zoom, theme.
  • plugin_ops(operation, ...) — Plugin management. Operations: discover, install, list, run.
  • status_ops(operation) — Server health. Operations: health_check, active_tab, process_info.

Multi-step Workflows (FastMCP 3.1)

  • agentic_notepad_workflow(workflow_prompt, available_tools) — Pass a natural-language goal like "open config.py, find the DEBUG flag, and toggle it". Requires sampling (Ollama or client LLM).
  • suggest_notepad_plan(goal) — Quick plan via ctx.sample when sampling is available. Returns structured step list for manual execution.

Workflow

  1. Status check: status_ops("health_check") to confirm Notepad++ process is accessible.
  2. File target: Use file_ops("info") to see active tab. Use file_ops("open", file_path=...) to open target.
  3. Act: Apply text ops, linting, or plugin commands as needed.
  4. Save/close: file_ops("save") or file_ops("close") to persist.

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.
