A plugin that connects an agent to Neo4j Graph Data Science, a toolkit for analysing relationships stored in a graph database. It provides a graph-analysis skill and can connect to a local Neo4j database or, optionally, Neo4j Aura services.

Use it to connect to Neo4j, select a database, and perform graph-data-science analysis through the plugin's MCP server.

It gives an agent access to graph data and graph-analysis operations without treating the information as ordinary tables. The configuration also separates database credentials and optional cloud-session credentials.

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.

Clone the repo

git clone --depth 1 https://github.com/neo4j-contrib/gds-agent

Made for: Gemini CLI.

Security

Grade A, and why

gds-agent 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 3d ago.

The scan reads gemini-extension.json. This mod also ships 1 executable file (scripts/bump_version.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.

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.
