What is copilot-mcp-server?

A connection to GitHub Copilot's development-assistance tools. It can provide coding help, debugging, explanations, architecture advice, and code reviews through Copilot models.

Use it to ask Copilot coding questions, investigate bugs, explain code, or request a focused review of a code snippet.

It gives the coding agent access to a separate AI assistant for tasks such as understanding code or reviewing it for security, performance, maintainability, and common practices.

copilot-mcp-server — Skill for Claude Code by Poorgramer-Zack

Install

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.

Any agent

npx skills add Poorgramer-Zack/copilot-mcp-tool --skill copilot-mcp-server

Clone the repo

git clone --depth 1 https://github.com/Poorgramer-Zack/copilot-mcp-tool

Made for: Claude Code.

Or install copilot-flow, the plugin that ships this one along with the rest of its 2 skills, 1 MCP server.

Token cost

What it costs to keep this loaded

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	$0.00021	$0.01465
Opus 5	$0.00010	$0.00732
Sonnet 5	$0.00004	$0.00293
Haiku 4.5	$0.00002	$0.00146

Security

Grade A, and why

copilot-mcp-server 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.
