What is vastai-host-mcp copilot-instructions.md?

Project-specific instructions for contributing to a TypeScript server that connects coding agents to Vast.ai host and provider workflows. They describe the project structure, setup, API references, and coding standards.

They help install and run the project, find its server and API code, and make changes that follow the repository’s conventions.

They give an agent the repository’s expected workflow and point it to the official Vast.ai documentation when changing API-related code.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01218	$0.01218
Opus 5	$0.00609	$0.00609
Sonnet 5	$0.00244	$0.00244
Haiku 4.5	$0.00122	$0.00122

Security

Grade A, and why

vastai-host-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 11d 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.

Copilot Instructions

Project Overview

This is the vastai-host-mcp repository. It provides a TypeScript FastMCP server focused on Vast.ai host/provider workflows.

Key contents:

MCP server implementation: src/index.ts with modular client/tools/rules
Host API client: src/client/VastAIHostClient.ts
Tool definitions: src/tools/hostTools.ts
Automation rules: src/rules/MCPRules.ts
Environment/config: .env.example, src/config.ts, src/logger.ts
Agent configurations: AGENTS.md, CLAUDE.md

Getting started

Refer to the README.md in the project root for setup and installation instructions.
Check also .tours/getting-started.tour which provides a guided walkthrough of key project features and structure.

Quick local setup:

pnpm install
cp .env.example .env
pnpm dev

Vast API References

When adding or changing host/provider endpoints, always validate against official Vast API docs first.

Start with the README section: Where to check Vast API in README.md.
Use docs index: https://docs.vast.ai/llms.txt
Use API intro: https://docs.vast.ai/api-reference/introduction
Prefer machine/search endpoint pages referenced in README.md for route/method validation.

Important rules for endpoint work:

Do not invent or guess endpoint paths.
Confirm both HTTP method and request payload shape from docs.
If an operation is not documented as API, prefer explicit CLI-only handling with clear messaging.

Coding Standards

TypeScript

Use TypeScript strict mode (tsconfig.json) and keep types explicit in MCP tools.
Define tool parameters with Zod and preserve stable tool names with vastai_host_ prefix.
Use VastAIHostClient for endpoint access; avoid ad-hoc HTTP calls in tools.
Keep host/provider scope only. Do not add renter-centric workflows in this server.
For undocumented host operations, prefer explicit CLI-only guidance over guessed API routes.

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.
