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 | $0.00950 | $0.00950 |
| Opus 5 | $0.00475 | $0.00475 |
| Sonnet 5 | $0.00190 | $0.00190 |
| Haiku 4.5 | $0.00095 | $0.00095 |
Grade A, and why
copilot-mcp-tool 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 9d 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

Code Architecture
High-Level Structure
This is a Model Context Protocol (MCP) server that bridges GitHub Copilot CLI with MCP-compatible AI clients (Claude Desktop, Cursor, etc.). The architecture follows a modular design:
src/
├── copilot/ # Main Copilot integration layer
│ ├── index.ts # Server entry point (#!/usr/bin/env node)
│ ├── server.ts # MCP server configuration & setup
│ ├── cli.ts # Copilot CLI execution wrapper
│ ├── session.ts # Session management & history
│ ├── constants.ts # Models, timeouts, paths, server info
│ ├── types.ts # Copilot-specific type definitions
│ ├── tools/ # MCP tool implementations (9 tools)
│ └── resources/ # MCP resource implementations (2 resources)
├── server/ # Core MCP server framework
│ ├── mcp.ts # McpServer class implementation

Key Components
1. MCP Server Core (src/server/)
- Implements the MCP protocol specification
- Handles tool registration, resource management, and communication
- Provides base classes for MCP 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.

copilot-mcp-tool CLAUDE.md is an instructions file published in the GitHub repository Poorgramer-Zack/copilot-mcp-tool (8 stars, last pushed 4mo ago), licensed MIT. It adds 950 tokens to every session, about $0.0047 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 2026-08-31.
