chembl

chembl is an MCP server for Claude Code from Shoko-official/Claude-Science-System-Prompts. Its token cost is not measured, scanned A, a copy of chembl, Apache-2.0.

A connection to ChEMBL and related health and life-sciences sources, including bioRxiv and medRxiv, which publish research papers before formal journal review. It lets the agent search and read those sources.

In plain words
What is it for?
Use it to look up chemical and biomedical research, preprints, and related health or clinical information.
Why use it?
It removes the need to search these research databases separately and copy their results into the agent.

MCP server for Claude Code

Written for Claude Code: shipped in a Claude Code plugin. Also seen: listed in a Claude config.

Part of the bio-research plugin — 11 MCP servers shipped together

One of 11 entries in .mcp.json upstream. Installing this one merges just its entry into your config; the other 10 are separate, each on its own page.

Good fit Use it to look up chemical and biomedical research, preprints, and related health or clinical information.

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.

Security

Grade A, and why

chembl 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 12d 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.

Origin

This is a copy

100% identical to chembl — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
