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 | $0.05103 | $0.05103 |
| Opus 5 | $0.02551 | $0.02551 |
| Sonnet 5 | $0.01021 | $0.01021 |
| Haiku 4.5 | $0.00510 | $0.00510 |
Grade A, and why
ultra-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 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.

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
This is an MCP (Model Context Protocol) server called "Ultra MCP" that exposes OpenAI, Gemini, Azure OpenAI, and xAI Grok AI models through a single MCP interface for use with Claude Code and Cursor. It also includes built-in vector indexing for semantic code search across your codebase. The project uses TypeScript, Node.js, the Vercel AI SDK, and libsql for vector storage.
Development Commands
# Install dependencies
bun install
# Build TypeScript
bun run build
# Run the MCP server locally (after building)
bun dist/cli.js
# Development mode with TypeScript watch
bun run dev
# Run tests
bun test
# Run tests with UI
bun run test:ui
# Run tests with coverage
bun run test:coverage
# Test with MCP Inspector
bunx @modelcontextprotocol/inspector bun dist/cli.js
# Configure API keys
bunx -y ultra-mcp config
# or after building locally:
bun dist/cli.js config
# Run via bunx (after publishing)
bunx -y ultra-mcp
CLI Commands
The Ultra MCP CLI provides several commands:
Default Command - MCP Server
When run without arguments, Ultra MCP starts as an MCP server using stdio protocol:
# Start MCP server (stdio protocol)
bunx -y ultra-mcp
# or locally:
bun dist/cli.js
config - Interactive Configuration
Configure API keys interactively (similar to rclone):
bunx -y ultra-mcp config
# or locally:
bun dist/cli.js config
Features:
- Interactive menu-driven interface
- Configure OpenAI, Google Gemini, Azure OpenAI, and xAI Grok API keys
- View current configuration (with masked API keys)
- Reset configuration
- API keys are stored securely in your system's config directory
doctor - Health Check
Check installation and configuration health:
bunx -y ultra-mcp doctor
# or locally:
bun dist/cli.js doctor
# Test connections to configured providers
bunx -y ultra-mcp doctor --test
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.

ultra-mcp CLAUDE.md is an instructions file published in the GitHub repository RealMikeChong/ultra-mcp (275 stars, last pushed 1y ago), licensed MIT. It adds 5,103 tokens to every session, about $0.0255 per session on Opus 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 2026-08-30.
