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-annotation/groupdocs.annotation.mcp/agents-mdgit clone --depth 1 https://github.com/groupdocs-annotation/GroupDocs.Annotation.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 | $0.01951 | $0.01951 |
| Opus 5 | $0.00975 | $0.00975 |
| Sonnet 5 | $0.00390 | $0.00390 |
| Haiku 4.5 | $0.00195 | $0.00195 |
Grade A, and why
GroupDocs.Annotation.Mcp AGENTS.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 yesterday.
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 — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — Guide for AI coding agents
Brief orientation for AI coding agents (Claude Code, Copilot, Cursor, Aider, Amp, Codex) working in this repository.
What this repo is
A standalone MCP server for GroupDocs.Annotation for .NET — exposes document annotation operations (add / list / update / remove / reply / import / export / preview) as AI-callable tools via the Model Context Protocol.
Published to NuGet as GroupDocs.Annotation.Mcp with the McpServer package type, and to ghcr.io/groupdocs-annotation/annotation-net-mcp + docker.io/groupdocs/annotation-net-mcp as a container image.
MCP tools exposed
| Tool | Description |
|---|---|
AddAnnotation |
Adds a textfield / area / point / arrow / highlight / underline / strikeout annotation; saves as <name>_annotated.<ext> |
GetAnnotations |
Lists all annotations as JSON (id, type, message, page, box, user, replies) |
UpdateAnnotation |
Updates an existing annotation's message and/or bounding box by id |
RemoveAnnotations |
Removes annotations by id list, or all if none specified |
AddReply |
Adds a reply to an existing annotation |
RemoveReplies |
Removes replies by reply-id list, by user name, or all |
ImportAnnotations |
Imports annotations from an XML file or another annotated document |
ExportAnnotations |
Extracts annotations to XML (re-importable via ImportAnnotations) |
GetDocumentInfo |
Returns file type, page count, size, and per-page dimensions as JSON (read-only) |
GeneratePagesPreview |
Renders up to 5 pages as inline PNG image content blocks (annotations baked in) |
All tools accept FileInput (resolved via IFileResolver) and an optional password for protected documents.

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.
