kafka

kafka is a cursor rule for Cursor from sfc-gh-cconner/support-rules-mcp. It costs 719 tokens per session, scanned A, original, Apache-2.0.

A set of coding guidance for connecting Apache Kafka, a system that streams event data, to Snowflake, a cloud data platform.

In plain words
What is it for?
Use it to investigate connection settings, validate configurations, process Kafka records, manage buffers, and review schema or Avro support in the Snowflake Kafka Connector.
Why use it?
It helps developers find relevant connector configuration, data-ingestion, and schema-management patterns without searching the connector's source code from scratch.

Cursor rule for Cursor

Written for Cursor: a Cursor rule (.mdc).

Getting it into your agent

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

kafka 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 5d 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.

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.
