api-connector

api-connector is a skill for Claude Code from glincker/claude-code-marketplace. It costs 24 tokens per session (3,338 once invoked), scanned B, original, Apache-2.0.

A natural-language connector for working with more than 100 popular APIs, including services such as GitHub, Slack, Stripe, Twilio, and OpenAI. An API is a defined way for one software system to request data or actions from another.

In plain words
What is it for?
It is for sending requests to supported services, setting up webhooks, handling rate limits and retries, testing calls, and generating integration code.
Why use it?
It removes much of the repetitive work of reading API documentation, building requests, handling authentication, and interpreting responses.

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 B, and why

api-connector scanned grade B with 2 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

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.
