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

onesignal-setup 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.

What it actually says

OneSignal Cursor Plugin Setup

Purpose

Help the user connect Cursor to OneSignal through the hosted OneSignal MCP server.

This plugin uses OAuth through the hosted OneSignal MCP server.

Required Setup

The user needs:

  • Cursor with plugin support.
  • A OneSignal account.

Authentication Guidance

Tell users to follow Cursor's OAuth prompt for the OneSignal MCP server. Never ask users to paste OAuth tokens, API keys, private keys, or credentials into chat, source files, rules, skills, commits, screenshots, or issue reports.

If Cursor was already open when the plugin was installed or updated, ask the user to reload Cursor with Developer: Reload Window or fully restart Cursor.

First Test

Use a read-only or utility MCP tool first. Prefer:

  • onesignal_health
  • onesignal_config
  • onesignal_reference_overview

Do not start with message sends, segment updates, template updates, Journey creation, exports, or subscription transfers.

Troubleshooting

If tools do not appear:

  1. Confirm the plugin is installed or symlinked into ~/.cursor/plugins/local/onesignal.
  2. Confirm .cursor-plugin/plugin.json is at the plugin root.
  3. Confirm mcp.json has a top-level mcpServers object.
  4. Reload Cursor.
  5. Check Cursor's MCP logs from the Output panel.

If tools appear but calls fail:

  1. Confirm the user completed the OneSignal OAuth flow in Cursor.
  2. Confirm the account has access to OneSignal MCP.
  3. Check whether the server URL is https://api.onesignal.com/mcp/oauth.
  4. Retry with a read-only utility tool.

Safety Defaults

For any write or send operation:

  • Prefer test users and narrow test audiences.
  • Summarize audience, content, timing, and expected effect.
  • Require explicit user approval before running the tool.
  • Add an extra confirmation for large audiences, production sends, deletes, or irreversible operations.

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.
