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 | $0.02947 | $0.02947 |
| Opus 5.5 | $0.01179 | $0.01179 |
| Sonnet 5.5 | $0.00589 | $0.00589 |
| Haiku 4.5 | $0.00295 | $0.00295 |
Grade A, and why
hevy-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.

Copilot Instructions for hevy-mcp
ALWAYS follow these instructions first and only fallback to search or additional context if the information here is incomplete or found to be in error.
Project Overview
- hevy-mcp is a Model Context Protocol (MCP) server for the Hevy Fitness API, enabling AI agents to manage workouts, routines, exercise templates, and folders via the Hevy API.
- The codebase is TypeScript (Node.js v20+), with a clear separation between tool implementations (
src/tools/), generated API clients (src/generated/), and utility logic (src/utils/). - API client code is generated from the OpenAPI spec using Kubb. Do not manually edit generated files.
- Type Safety: The project uses Zod schema inference for type-safe tool parameters, eliminating manual type assertions and ensuring compile-time type safety.
Working Effectively
Bootstrap and Build Repository
Run these commands in order to set up a working development environment (Corepack is bundled with Node.js v20+, so run corepack use [email protected] once per machine if pnpm isn't available):
-
Install dependencies:
pnpm install- Takes approximately 30 seconds. NEVER CANCEL - set timeout to 60+ seconds.
-
Build the project:
pnpm run build- Takes approximately 3-5 seconds. TypeScript compilation via tsdown.
- Always build before running the server or testing changes.
-
Run linting/formatting:
pnpm run check- Takes less than 1 second.
- EXPECTED WARNING: Biome schema version mismatch warning is normal and can be ignored.
Testing Commands
-
Run unit tests only:
pnpm vitest run --exclude tests/integration/**- Takes approximately 1-2 seconds. NEVER CANCEL.
- This is the primary testing command for development.
-
Run integration tests (requires API key):
pnpm vitest run tests/integration
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.
