Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00158 | $0.03353 |
| Opus 5.5 | $0.00063 | $0.01341 |
| Sonnet 5.5 | $0.00032 | $0.00671 |
| Haiku 4.5 | $0.00016 | $0.00335 |
Grade B, and why
neo4j-mcp-skill scanned grade B with 1 finding 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 1mo 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
**Claude Code** — add to `~/.claude/settings.json`. If the file already exists, merge the `neo4j` block into the existing `mcpServers` object — do not replace the whole file. How it starts
The opening of the file, as written. The whole thing — 315 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Neo4j MCP Skill
Installs and configures the official Neo4j MCP server so AI agents can connect to Neo4j via any MCP-compatible client.
When to Use
- Connecting Claude Code, Claude Desktop, Cursor, Windsurf, VS Code, Kiro, or another editor to Neo4j via MCP
- Installing
neo4j-mcp-serverand writing the correct config for a specific editor - Switching between stdio and HTTP transport
- Enabling or disabling write access (
NEO4J_READ_ONLY) - Troubleshooting "MCP server not found" or connection errors
When NOT to Use
- Writing or optimizing Cypher queries → use
neo4j-cypher-skill - Provisioning a new Neo4j Aura instance → use
neo4j-aura-provisioning-skill - Agent long-term memory → use
neo4j-agent-memory-skill - neo4j-admin / cypher-shell / aura-cli → use
neo4j-cli-tools-skill
Available MCP Tools
| Tool | Type | What it does |
|---|---|---|
get-schema |
read | Returns labels, relationship types, property keys, and indexes |
read-cypher |
read | Executes read-only Cypher (MATCH, RETURN, SHOW) |
write-cypher |
write | Executes write Cypher (MERGE, CREATE, SET, DELETE) — disabled when NEO4J_READ_ONLY=true |

Installation
Step 1 — Install and find the absolute path
# Option A: pip (recommended)
pip install neo4j-mcp-server
# Option B: Download binary
# https://github.com/neo4j/mcp/releases -- macOS, Linux, Windows binaries
# Option C: Docker
docker pull neo4j/mcp
Get the absolute path — you will need this in Step 3:
which neo4j-mcp # e.g. /usr/local/bin/neo4j-mcp
# or: /Users/you/project/.venv/bin/neo4j-mcp (if installed in venv)
neo4j-mcp --version # confirm it runs
Why absolute path matters: editors (Claude Code, Cursor, Claude Desktop) spawn the MCP server as a subprocess using their own restricted PATH — not your shell's PATH. On macOS, GUI apps do not inherit
.zshrcor.zprofile. Usingneo4j-mcpas the command will silently fail; using/full/path/to/neo4j-mcpalways works. Always use the output ofwhich neo4j-mcpin thecommandfield below.
What ships with it
1 file 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.
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.

neo4j-mcp-skill is a skill published in the GitHub repository neo4j-contrib/neo4j-skills (116 stars, last pushed yesterday), licensed MIT. It adds 158 tokens to every session and 3,353 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
