oss-boundary

oss-boundary is a cursor rule for Cursor from extralabs/octowatch-mcp-server. It costs 330 tokens per session, scanned A, original, MIT.

A set of rules for keeping a public open-source repository separate from private OctoWatch code and data. It defines what may be documented or committed and what must remain private, including secrets, customer data, and proprietary implementation details.

In plain words
What is it for?
Use it when reviewing code, documentation, examples, commits, and API notes for public-release safety.
Why use it?
It reduces the risk of publishing credentials, internal infrastructure, private source code, or customer information in a public repository.

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

oss-boundary 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 6d 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

Public OSS safety (octowatch-mcp-server)

This repository is public open source. Anything committed or pasted into docs/examples/code here can be published.

Private sibling code (reference only)

The maintainer may have local private frontend/backend checkouts. Use them only to discover public API contracts, request shapes, and field names.

Do not:

  • Commit absolute local disk paths to those private repos
  • Vend, paste, or rewrite large chunks of their source into this repo
  • Document internal module layouts beyond what is needed for the public REST client

Never put in this repo

  • Production passwords, tokens, connection strings, private keys, certs, cloud keys
  • Non-public internal hosts (documented Cloud API host is OK)
  • Full proprietary modules, controllers, business rules, licensing, billing, OCR pipelines
  • Customer data dumps or raw monitoring payloads from non-demo tenants

Allowed

  • Public demo credentials ([email protected] / demo) with clear warnings
  • Documented REST paths, headers, and JSON shapes needed for the MCP client
  • Minimal original OSS code that calls the public API
  • High-level notes in docs/ that describe behavior, not internal implementation

When in doubt

Prefer re-deriving from live public Help/API docs and demo responses. If a change would only make sense with private backend knowledge that competitors could abuse, leave it out or ask the user.

Changes

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.
