Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

Search 18 research-data sources at once (data archives, omics repositories and papers) and get one list back. Organism, disease and tissue names are expanded with their synonyms in the 12 sources that accept them, records that share a DOI are collapsed to one, and downloads are checked against the source's checksum where it publishes one.

Questions

What is the data-aggregator-mcp MCP server?

Unified research-data acquisition MCP — search & fetch datasets across Zenodo, DataCite, NCBI omics (GEO/SRA/BioProject), and literature (PubMed/OpenAIRE) behind one normalized model.

Is data-aggregator-mcp safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it C (73/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does data-aggregator-mcp need?

It reads DATA_GOV_API_KEY, EMBEDDING_API_KEY, LLM_API_KEY and NCBI_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does data-aggregator-mcp run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on PyPI as data-aggregator-mcp.

How current is this page?

The grade is for one exact copy of the source (46cf60095b50), read on 2026-10-11. The repository is watched and re-audited when it changes.
