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 | $0.00843 | $0.00843 |
| Opus 5 | $0.00421 | $0.00421 |
| Sonnet 5 | $0.00169 | $0.00169 |
| Haiku 4.5 | $0.00084 | $0.00084 |
Grade A, and why
atlas-mcp-server CLAUDE.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 10d 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.

Core Architecture
ATLAS is an MCP (Model Context Protocol) server with a three-tier Neo4j-backed architecture:
Transport Layer (src/mcp/transports/):
stdioTransport.ts- Direct stdio communication (default)httpTransport.ts- HTTP server with authentication/rate limiting
MCP Layer (src/mcp/):
server.ts- Main MCP server setup, tool/resource registrationtools/- MCP tool implementations (15 total tools)resources/- MCP resource handlers for direct data access
Data Layer (src/services/neo4j/):
- Core services:
projectService.ts,taskService.ts,knowledgeService.ts searchService.ts- Unified search across all entitiesbackupRestoreService.ts- Database backup/restore operations
Three-Tier Data Model:
PROJECT (top-level containers)
├── TASK (actionable items within projects)
├── KNOWLEDGE (information/context for projects)
└── DEPENDENCIES (relationships between entities)
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.
