kegg-pathway

kegg-pathway is a command for Claude Code from Lucas-Servi/kegg-mcp-server-python. It costs 18 tokens per session (250 once invoked), scanned A, original, MIT.

A command for exploring a KEGG biological pathway in detail. It can find a pathway from an ID or keyword, then summarize its genes, compounds, reactions, and an ASCII diagram.

In plain words
What is it for?
Use it to inspect a pathway, its key enzymes and metabolites, related diseases or drugs when available, and a text-based pathway overview.
Why use it?
It organizes several KEGG lookups into one pathway-focused investigation.

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

kegg-pathway 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 5d 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 it actually says

Pathway Deep-Dive

Provide a comprehensive overview of a KEGG pathway.

  1. If $ARGUMENTS looks like a pathway ID (e.g., hsa00010, map00010), use it directly. Otherwise call search_pathways with the argument as a keyword and pick the top result.
  2. Call get_pathway_info with full detail.
  3. Call get_pathway_genes to list key enzymes.
  4. Call get_pathway_compounds to list metabolites.
  5. Call render_pathway_ascii in chain mode for an overview diagram.
  6. Present a structured summary:
    • Pathway name and organism
    • Biological function (1-2 sentences)
    • Key enzymes (with EC numbers)
    • Key metabolites
    • ASCII diagram
    • Related diseases or drugs (if any in the pathway data)
    • Suggested follow-ups: "Try /kegg-drug for drugs targeting this pathway, or ask for a cross-species comparison."

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.

kegg-pathway is a command published in the GitHub repository Lucas-Servi/kegg-mcp-server-python (3 stars, last pushed 23d ago), licensed MIT. It adds 18 tokens to every session and 250 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
