Instructions file for GitHub Copilot

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

This is mapbox/mcp-docs-server's own configuration. It tells GitHub Copilot how to work on mcp-docs-server 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 mcp-docs-server 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

mcp-docs-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 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.

What it actually says

GitHub Copilot Guidelines

This repository is the Mapbox MCP Documentation Server — a TypeScript MCP server providing AI assistants with Mapbox documentation and reference materials.

Key Facts

  • Tools extend BaseTool (not MapboxApiBasedTool — that class lives in a different repo)
  • BaseTool.execute(input) takes only the validated input — no accessToken or context params
  • No Mapbox access token is needed for most tools; if required, accept it as an input field
  • HTTP requests use the shared httpRequest from src/utils/httpPipeline.ts — never patch global.fetch
  • Tests mock httpRequest with vi.fn() — no real network calls in tests

Before Accepting Suggestions

  • Verify the suggestion uses BaseTool, not MapboxApiBasedTool
  • Verify execute(input) has the correct signature (no extra params)
  • Verify HTTP calls go through the injected httpRequest, not fetch directly
  • Verify no secrets or tokens are hardcoded

Standards

  • TypeScript strict mode — no implicit any
  • All new tools/resources need tests in test/ mirroring the src/ structure
  • Update CHANGELOG.md under Unreleased with every user-facing change

See CONTRIBUTING.md and CLAUDE.md for full patterns and examples.

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.
