api-context

api-context is a skill for Claude Code from cyanheads/bls-labor-mcp-server. It costs 79 tokens per session (11,090 once invoked), scanned A, original, no licence file.

A reference for the shared Context object passed to every tool and resource handler in @cyanheads/mcp-ts-core. It explains the request information, inputs, state, logging, user-input requests, enrichment, and content APIs available through that object.

In plain words
What is it for?
Use it when implementing or reviewing tool and resource handlers that use @cyanheads/mcp-ts-core's Context object.
Why use it?
It provides one place to check how handlers receive information and interact with the surrounding tool framework. This helps developers use the correct Context API for each task.

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

api-context scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
