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 | $0.08213 | $0.08213 |
| Opus 5 | $0.04106 | $0.04106 |
| Sonnet 5 | $0.01643 | $0.01643 |
| Haiku 4.5 | $0.00821 | $0.00821 |
Grade C, and why
mcp-neo4j-knowledge-graph CLAUDE.md scanned grade C 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 yesterday.
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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Project Overview
@henrychong-ai/mcp-neo4j-knowledge-graph is a Model Context Protocol (MCP) server implementing a Neo4j-based knowledge graph with temporal versioning and semantic search capabilities. Maintained by Henry Chong, built on foundational work by Gannon Hall.
Key Features:
- Temporal versioning for entities and relations (track historical changes)
- Neo4j graph database as primary storage backend
- Vector embeddings and semantic search via OpenAI
- MCP server for Claude Desktop and Claude Code integration
- Full test coverage with Vitest

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.

mcp-neo4j-knowledge-graph CLAUDE.md is an instructions file published in the GitHub repository henrychong-ai/mcp-neo4j-knowledge-graph (1 stars, last pushed yesterday), licensed MIT. It adds 8,213 tokens to every session, about $0.0411 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
