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-redaction/groupdocs.redaction.mcp/agents-mdgit clone --depth 1 https://github.com/groupdocs-redaction/GroupDocs.Redaction.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 | $0.01627 | $0.01627 |
| Opus 5 | $0.00813 | $0.00813 |
| Sonnet 5 | $0.00325 | $0.00325 |
| Haiku 4.5 | $0.00163 | $0.00163 |
Grade A, and why
GroupDocs.Redaction.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 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 — 116 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.Redaction for .NET — exposes document redaction operations as AI-callable tools via the Model Context Protocol.
Published to NuGet as GroupDocs.Redaction.Mcp with the McpServer package type, and to ghcr.io/groupdocs-redaction/redaction-net-mcp + docker.io/groupdocs/redaction-net-mcp as a container image.
MCP tools exposed
| Tool | Description |
|---|---|
RedactText |
Redact text matching a regex pattern in a document; saves result as <name>_redacted.<ext> |
EraseMetadata |
Erase document metadata fields (author, title, company, dates, and other properties) |
RedactAnnotations |
Replace or delete annotations and comments in a document |
RedactImageArea |
Cover a rectangular page region with a solid-color box (pixel coordinates) |
GetDocumentInfo |
Return file type, page count, size, and per-page dimensions as JSON (no modification) |
All tools accept FileInput (resolved via IFileResolver). The four redaction tools (RedactText, EraseMetadata, RedactAnnotations, RedactImageArea) write output files to storage; GetDocumentInfo is read-only and returns JSON.

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.
