pi-ntn

A pi coding agent extension that wraps the official Notion ntn CLI as a single typed tool — directly, not via an MCP server.

What it provides

• an ntn custom tool with typed parameters (subcommand + args map + data + method + timeoutSeconds + forceDangerous)
• a bundled SKILL.md documenting the tool and common ntn commands
• per-turn prompt guidance when a prompt mentions Notion, pages, databases, data sources, or workspaces
• graceful detection of the "not authenticated" failure with actionable guidance
• a safety guard that refuses pages trash unless forceDangerous: true is set

Why not MCP?

The ntn CLI already exposes the full Notion API (pages, databases, data sources, search, raw API) and uses the user's existing ntn login credentials. Wrapping it in a typed pi tool gives structured, discoverable parameters and output truncation without an extra server process — and replaces the notion MCP server.

Requirements

• ntn CLI on PATH — notion.so
• Authenticated via ntn login

Installation

Drop the extension into ~/.pi/agent/extensions/ (global) or .pi/extensions/ (project-local), then reload:

/reload

Or install from git:

pi install git:github.com/sfroment/pi-ntn

Tool parameters

Parameter	Type	Description
subcommand	string	The full ntn subcommand path (e.g. "pages get <id>", "api /v1/search", "datasources query <id>"). Top-level — never nest inside args.
args	object	A key/value object of flags ONLY — never an array, and do not nest subcommand/data/method here. Booleans → bare --flag ({json: true} → --json). Strings/numbers → --flag value ({parent: "page:abc"} → --parent page:abc). Arrays → repeated --flag value pairs. false/null/undefined are skipped.
data	string	Request body for api calls — a JSON string, @path, or @- for stdin (translates to --data).
method	string	HTTP method override for api calls (translates to --method).
timeoutSeconds	integer	Command timeout (default 30, max 120).
forceDangerous	boolean	Opt-in for pages trash (the delete-class op). Requires explicit user confirmation.

Examples

Get a page as Markdown:

{
  "subcommand": "pages get <page-id>",
  "args": { "json": true }
}

Search the workspace:

{
  "subcommand": "api /v1/search",
  "data": "{\"query\":\"meeting notes\",\"filter\":{\"property\":\"object\",\"value\":\"page\"}}"
}

List file uploads:

{
  "subcommand": "files list"
}

Check the CLI health:

{
  "subcommand": "doctor"
}
