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.
npx agentmods add instructions/groupdocs-comparison/groupdocs.comparison.mcp/copilot-instructionsgit clone --depth 1 https://github.com/groupdocs-comparison/GroupDocs.Comparison.McpWhat 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 | $0.01029 | $0.01029 |
| Opus 5 | $0.00515 | $0.00515 |
| Sonnet 5 | $0.00206 | $0.00206 |
| Haiku 4.5 | $0.00103 | $0.00103 |
Grade A, and why
GroupDocs.Comparison.Mcp 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 2d 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
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub Copilot instructions — GroupDocs.Comparison MCP Server
This repository is a standalone MCP (Model Context Protocol) server that exposes GroupDocs.Comparison for .NET as AI-callable tools for Claude, Cursor, GitHub Copilot, and other MCP clients.
Published to NuGet as GroupDocs.Comparison.Mcp (PackageType=McpServer) and as container images at ghcr.io/groupdocs-comparison/comparison-net-mcp and docker.io/groupdocs/comparison-net-mcp. MIT-licensed.
Run / install
# Run directly with dnx (recommended — no install step); pin with @<version> for shared configs/CI
dnx GroupDocs.Comparison.Mcp --yes
# Or install as a global dotnet tool
dotnet tool install -g GroupDocs.Comparison.Mcp
groupdocs-comparison-mcp
# Or run via Docker
docker run --rm -i -v $(pwd)/documents:/data ghcr.io/groupdocs-comparison/comparison-net-mcp:latest
MCP tools exposed (3)
- Compare — compare two documents (source vs target), produce a marked-up result file with differences highlighted, plus a change-count summary and a structured JSON change list (type, page, changed fragment, source/target text, table cell, style changes). Optional
sourcePassword/targetPassword. - AnalyzeChanges — return the differences as structured data only (same JSON change list as Compare) without rendering or saving a result file. Cheaper than Compare; for summarizing/reasoning about what changed. Optional
sourcePassword/targetPassword. - GetDocumentInfo — inspect a single source document and return file type, page count, file size, and per-page dimensions as JSON; no comparison. Optional
password.
Supported formats: PDF, DOCX, XLSX, PPTX, ODT, ODS, ODP, RTF, TXT, HTML, and 30+ more.

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.

GroupDocs.Comparison.Mcp copilot-instructions.md is an instructions file published in the GitHub repository groupdocs-comparison/GroupDocs.Comparison.Mcp (1 stars, last pushed 7d ago), licensed MIT. It adds 1,029 tokens to every session, about $0.0051 per session on Opus 5. A static security scan graded it A with 0 findings.
