Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a file path from a variable internal/analytics/analytics.go:187

            return filepath.Join("<home>", rel)

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

Neo4j MCP Canary — questions

Answers built from our own checks of this server.

Why is there no uptime for Neo4j MCP Canary?

Neo4j MCP Canary runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package neo4j-mcp-canary was installed 523 times last week.

How do I connect Neo4j MCP Canary?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls neo4j-mcp-canary straight from pypi; nothing to host, nothing to sign up for.

How many people use Neo4j MCP Canary?

The pypi package neo4j-mcp-canary was installed 523 times in the last week. Week over week that is +31%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Neo4j MCP Canary open source?

We cannot say either way: written in Go and 2 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
