microsoft/mcp-dotnet-samples is a collection of .NET examples showing how to build and use Model Context Protocol servers and clients. MCP is an open standard for connecting large language models with data sources and tools, so developers can create integrations and agent workflows. The catalogue entries are sample MCP servers, clients, and setup instructions.

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 | $0.02417 | $0.02417 |
| Opus 5.5 | $0.00967 | $0.00967 |
| Sonnet 5.5 | $0.00483 | $0.00483 |
| Haiku 4.5 | $0.00242 | $0.00242 |
Grade A, and why
mcp-dotnet-samples 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 2mo 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 — 330 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md - MCP .NET Samples
Project Overview
The Model Context Protocol (MCP) .NET Samples repository demonstrates how to build MCP servers using .NET 9.0. This repository contains four comprehensive sample implementations that showcase different aspects of MCP server development, from GitHub integration to web services, data management, and email communications.

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.
