What is database-lookup?

A lookup tool for querying 78 public scientific, medical, materials, and economic databases through web APIs. It selects relevant databases and returns their raw JSON results.

Use it to look up compounds, genes, pathways, patents, expression data, astronomy and environmental records, materials information, or economic indicators.

It removes the need to know which database contains a particular kind of information or how to format each database's request. It also makes clear when a search finds nothing.

Install

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.

Any agent

npx skills add Lord1Egypt/scientific-agent-toolkit --skill database-lookup

Clone the repo

git clone --depth 1 https://github.com/Lord1Egypt/scientific-agent-toolkit

Made for: Claude Code, Codex.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00242	$0.07465
Opus 5.5	$0.00097	$0.02986

Security

Grade B, and why

database-lookup 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 1mo 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.

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

These databases require HTTP POST and **will not work with WebFetch** (GET-only). Use `curl` via your platform's shell tool instead:

How it starts

The opening of the file, as written. The whole thing — 481 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Database Lookup

You have access to 78 public databases through their REST APIs. Your job is to figure out which database(s) are relevant to the user's question, query them, and return the raw JSON results along with which databases you used.

Core Workflow

Understand the query — What is the user looking for? A compound? A gene? A pathway? A patent? Expression data? An economic indicator? This determines which database(s) to hit.
Select database(s) — Use the database selection guide below. When in doubt, search multiple databases — it's better to cast a wide net than to miss relevant data.
Read the reference file — Each database has a reference file in references/ with endpoint details, query formats, and example calls. Read the relevant file(s) before making API calls.
Make the API call(s) — See the Making API Calls section below for which HTTP fetch tool to use on your platform.
Return results — Always return:
- The raw JSON response from each database
- A list of databases queried with the specific endpoints used
- If a query returned no results, say so explicitly rather than omitting it

Database Selection Guide

Match the user's intent to the right database(s). Many queries benefit from hitting multiple databases.

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.

database-lookup is a skill published in the GitHub repository Lord1Egypt/scientific-agent-toolkit (3 stars, last pushed 4mo ago), licensed MIT. It adds 242 tokens to every session and 7,465 once invoked, about $0.0010 per session on Opus 5.5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). It is 98% identical to database-lookup, differing in 2 lines, and is treated as a copy.
