Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00196 | $0.00196 |
| Opus 5 | $0.00098 | $0.00098 |
| Sonnet 5 | $0.00039 | $0.00039 |
| Haiku 4.5 | $0.00020 | $0.00020 |
Grade A, and why
port-safety 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 2d 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.
This is a copy
100% identical to port-safety — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Port MCP rules
Knowledge lookup
Before answering any question about Port concepts (blueprints, scorecards, entities, actions, workflows, integrations, relations, properties, permissions) or before taking any action that requires Port-specific knowledge, call search_port_knowledge_sources with the relevant query.
Do not rely on training data alone for Port-specific behavior, configuration options, or API semantics. Always verify against the official documentation first.
Write confirmation
Before calling any tool that creates, updates, deletes, or triggers anything in Port, confirm the operation with the user first.
Confirmation must include:
- What will change and on which resource
- Whether the operation is reversible
- An explicit user approval before the tool call is made
Do not proceed with write operations based on implied intent.
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.

port-safety is a cursor rule published in the GitHub repository port-labs/cursor-plugin (0 stars, last pushed 1mo ago), licensed MIT. It adds 196 tokens to every session, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to port-safety, differing in 0 lines, and is treated as a copy.
