bioservices

A Python interface for accessing more than 40 bioinformatics databases and web services. It combines sources such as UniProt, KEGG, ChEMBL and Reactome in one workflow.

In plain words
What is it for?
Retrieving protein information, pathway and gene-function data, chemical records, sequence searches, and matching identifiers between biological databases.
Why use it?
It avoids writing separate integrations for each database and helps keep cross-database queries consistent. It can also handle different web connection methods behind one interface.

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

bioservices 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 yesterday.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/batch_id_converter.py, scripts/compound_cross_reference.py, scripts/pathway_analysis.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

81% identical to bioservices — 20 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.

BioServices

Overview

BioServices is a Python package providing programmatic access to approximately 40 bioinformatics web services and databases. Retrieve biological data, perform cross-database queries, map identifiers, analyze sequences, and integrate multiple biological resources in Python workflows. The package handles both REST and SOAP/WSDL protocols transparently.

Version note: Examples target bioservices 1.16.0 (PyPI, Mar 2026). Requires Python 3.9–3.12. UniProt REST changes in mid-2022 (bioservices ≥1.10) mainly affect tabular columns names — see upstream _legacy_names if parsing breaks. ChEMBL wrappers changed at 1.6.0 (2018 API); use get_similarity, get_substructure, get_molecule instead of pre-1.6 method names.

When to Use This Skill

This skill should be used when:

  • Retrieving protein sequences, annotations, or structures from UniProt, PDB, Pfam
  • Analyzing metabolic pathways and gene functions via KEGG or Reactome
  • Searching compound databases (ChEBI, ChEMBL, PubChem) for chemical information
  • Converting identifiers between different biological databases (KEGG↔UniProt, compound IDs)
  • Running sequence similarity searches (BLAST, MUSCLE alignment)
  • Querying gene ontology terms (QuickGO, GO annotations)
  • Accessing protein-protein interaction data (PSICQUIC, IntactComplex)
  • Mining genomic data (BioMart, ArrayExpress, ENA)
  • Integrating data from multiple bioinformatics resources in a single workflow

Core Capabilities

1. Protein Analysis

Retrieve protein information, sequences, and functional annotations:

from bioservices import UniProt

u = UniProt(verbose=False)

# Search for protein by name
results = u.search("ZAP70_HUMAN", frmt="tab", columns="id,genes,organism")

# Retrieve FASTA sequence
sequence = u.retrieve("P43403", "fasta")

# Map identifiers between databases
kegg_ids = u.mapping(fr="UniProtKB_AC-ID", to="KEGG", query="P43403")

Key methods:

  • search(): Query UniProt with flexible search terms
  • retrieve(): Get protein entries in various formats (FASTA, XML, tab)
  • mapping(): Convert identifiers between databases

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

bioservices is a skill published in the GitHub repository dralkh/seerai (77 stars, last pushed 1mo ago), licensed MIT. It adds 73 tokens to every session and 2,869 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 81% identical to bioservices, differing in 20 lines, and is treated as a copy.
