seq-mcp: Instructions file for GitHub Copilot

.github/copilot-instructions.md

seq-mcp copilot-instructions.md is an instructions file for GitHub Copilot from MCLifeLeader/seq-mcp. It costs 207 tokens per session, scanned A, original, MIT.

Repository guidance for building a Dockerized MCP server that gives AI agents controlled access to Seq observability data. Seq is a system for searching application logs and telemetry; Docker packages the server for repeatable runs.

In plain words
What is it for?
Use it when developing or reviewing the seq-mcp server, especially its MCP tools, Seq requests, Docker setup, validation, and security behavior.
Why use it?
It sets rules for secure external queries, secret handling, container-based development, and clear tool contracts, reducing avoidable engineering and security mistakes.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file. Also seen: mentions Codex.

This is MCLifeLeader/seq-mcp's own configuration. It tells GitHub Copilot how to work on seq-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything seq-mcp configures →

Token cost

What 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.

Security

Grade A, and why

seq-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 1mo 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

Copilot Instructions for seq-mcp

This repository is dedicated to building a Dockerized MCP server that provides AI agents (for example Codex and Copilot) with controlled access to Datalust Seq OpenTelemetry data.

Priority Rules

  1. Follow .github/instructions/seq-mcp-server.instructions.md first.
  2. Apply security guidance from .github/instructions/security-and-owasp.instructions.md.
  3. Apply container guidance from .github/instructions/containerization-docker-best-practices.instructions.md.

If rules conflict, the more specific Seq MCP rule wins.

Engineering Expectations

  • Model all external interactions as explicit MCP tools with clear input/output contracts.
  • Validate and constrain query inputs before issuing any Seq request.
  • Never hardcode secrets; use environment variables.
  • Design for container-first execution and reproducible local runs.
  • Favor small, testable components with observable behavior.

Out of Scope

  • Generic scaffolding unrelated to Seq MCP integration.
  • Legacy compatibility work that weakens clarity or security.
Changes

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.
