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 | $0.00321 | $0.00321 |
| Opus 5 | $0.00161 | $0.00161 |
| Sonnet 5 | $0.00064 | $0.00064 |
| Haiku 4.5 | $0.00032 | $0.00032 |
Grade A, and why
neo4j-mcp AGENTS.md 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 8d 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.
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 it actually says
Repository Guidelines
Project Structure & Module Organization
neo4j_mcp/contains the MCP server package, including driver integration, query helpers, schemas, and tool definitions.settings/stores configuration defaults, andtests/should mirror the package structure for query, node, relationship, and path coverage.- Keep operator guidance in root docs rather than ad hoc scripts.
Build, Test, and Development Commands
uv sync --group devinstalls development dependencies.- Use the documented local stdio or HTTP server commands for smoke tests.
uv run pytestruns the test suite.uv run ruff check neo4j_mcp testsanduv run ruff format neo4j_mcp testscover linting and formatting.
Coding Style & Naming Conventions
- Use explicit type hints, parameterized queries, and small composable helpers around the Neo4j driver.
- Keep modules snake_case, classes PascalCase, and tool responses structured and validated.
Testing Guidelines
- Add tests for Cypher execution, schema inspection, and path-finding behavior.
- Prefer mocked or containerized graph setups over depending on a shared live database.
Commit & Pull Request Guidelines
- Use focused commits such as
feat(paths): add shortest path tool options. - PRs should call out query behavior changes, commands run, and any compatibility implications.
Security & Configuration Tips
- Never commit database credentials or internal connection URIs.
- Validate user-supplied labels, property filters, and query parameters strictly.
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.
