data-researcher

data-researcher is an agent for Claude Code from alexmmatos/arthur-mcp. It costs 54 tokens per session (1,346 once invoked), scanned A, original, MIT.

A data-research agent that finds, collects, checks, and prepares information from multiple sources for later analysis. Its sources can include APIs, databases, public datasets, web pages, surveys, sensors, logs, and archives.

In plain words
What is it for?
Use it to identify sources, gather datasets, connect to APIs or databases, scrape web data, clean information, and prepare it for analysis or modeling.
Why use it?
It reduces the work of locating usable data and checking whether the collected information is complete and reliable.

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

data-researcher 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 9d 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 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.
