Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00186 | $0.00186 |
| Opus 5 | $0.00093 | $0.00093 |
| Sonnet 5 | $0.00037 | $0.00037 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
mcp-copilotcli-history copilot-instructions.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 5d 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
Copilot Instructions
Project Overview
This is an MCP (Model Context Protocol) server that provides tools for searching GitHub Copilot CLI conversation history stored in ~/.copilot/session-state/ JSONL files.
Tech Stack
- Python 3.13+
- uv for environment management
- FastMCP (
mcppackage) for MCP server implementation - Hatchling for build system
Key Commands
- Install:
uv pip install -e . - Run server:
mcp-copilotcli-historyorpython -m mcp_copilotcli_history
Code Guidelines
- Use type hints for all function signatures
- Keep functions focused and single-purpose
- Handle file I/O errors gracefully with try/except
- Use
Pathfrompathlibfor file operations - Return meaningful error dictionaries instead of raising exceptions in MCP tools
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.

mcp-copilotcli-history copilot-instructions.md is an instructions file published in the GitHub repository MicroMichaelIE/mcp-copilotcli-history (4 stars, last pushed 9mo ago), licensed MIT. It adds 186 tokens to every session, about $0.0009 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.
