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 | $0.03650 | $0.03650 |
| Opus 5.5 | $0.01460 | $0.01460 |
| Sonnet 5.5 | $0.00730 | $0.00730 |
| Haiku 4.5 | $0.00365 | $0.00365 |
Grade A, and why
db-mcp 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 2mo 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.
How it starts

Project Overview
db-mcp is an MCP (Model Context Protocol) server that enables Claude Desktop to query databases using natural language. It was extracted from the semantic-grid project as a standalone component.
The server:
- Introspects database schemas automatically
- Builds a semantic understanding of data through interactive onboarding
- Generates and validates SQL from natural language
- Supports multiple database backends
Roadmap Vision
The docs/ directory contains design documents for planned features:
- Metrics Layer (
metrics-layer.md) - Semantic metrics definitions for consistent business KPIs - Knowledge Extraction Agent (
knowledge-extraction-agent.md) - Background agent that learns from query traces - Electron Desktop App (
electron-port-feasibility.md) - Desktop GUI with Electron shell + db-mcp sidecar - Semantic Data Gateway (
data-gateway.md) - Unified gateway for multiple data sources (CSV, BI tools, dbt)

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.

db-mcp CLAUDE.md is an instructions file published in the GitHub repository apelogic-ai/db-mcp (6 stars, last pushed 6mo ago), licensed MIT. It adds 3,650 tokens to every session, about $0.0146 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
