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.

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 | $0.00324 | $0.00324 |
| Opus 5 | $0.00162 | $0.00162 |
| Sonnet 5 | $0.00065 | $0.00065 |
| Haiku 4.5 | $0.00032 | $0.00032 |
Grade A, and why
testrail-mcp-server 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 5d 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.
What it actually says
TestRail MCP Server - Copilot Instructions
Project Overview
This is a Model Context Protocol (MCP) server that enables AI assistants to automatically create test cases in TestRail through the TestRail API. The server provides tools for:
- Creating test cases with different templates (Text, Steps, Exploratory)
- Managing projects, sections, and suites
- Retrieving test case information
- Handling authentication with TestRail
Key Technologies
- TypeScript/Node.js for the MCP server
- TestRail REST API v2
- Model Context Protocol (MCP) specification
- HTTP Basic Authentication
Project Structure
src/- TypeScript source filesdist/- Compiled JavaScript outputdocs/- Documentation and examples- Configuration files for TypeScript, npm, and MCP
Development Guidelines
- Follow TypeScript strict mode practices
- Implement proper error handling for API calls
- Use environment variables for sensitive configuration
- Provide comprehensive JSDoc documentation
- Include examples for each MCP tool
TestRail Integration
- Support for TestRail Cloud and Server instances
- API key authentication recommended over password
- Handle rate limiting and error responses
- Support for custom fields and templates
MCP SDK Reference
- TypeScript SDK: https://github.com/modelcontextprotocol/typescript-sdk
- Follow MCP specification: https://spec.modelcontextprotocol.io/
- Use @modelcontextprotocol/sdk package
- Implement stdio transport for local servers
Status: ✅ Copilot instructions updated with MCP SDK info
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.

testrail-mcp-server copilot-instructions.md is an instructions file published in the GitHub repository janainarocha/testrail-mcp-server (2 stars, last pushed 6mo ago), licensed MIT. It adds 324 tokens to every session, about $0.0016 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
