| Best for | - Users who want the control loop and state kept on their device
- Users with llama.cpp, Ollama, LM Studio, or another OpenAI-compatible model backend
- Developers needing browser, filesystem, document, and task automation
- Technical users willing to review approvals, traces, and network egress
| - Hevy PRO users who want AI assistants to directly access their workout data
- People who prefer using MCP clients like Claude, Cursor, Codex for fitness tracking
- Anyone needing summaries and insights from their training data
| - Scenarios needing clean, structured web context fed to an AI assistant
- Users already on the Firecrawl platform who want to call its scraping capability directly via MCP
|
|---|
| Not for | - Users looking for a standalone MCP server that can be installed directly into an MCP client
- Production integrations requiring stable APIs, because the project is still a developer preview
- Environments that cannot allow agent access to browsers, files, shells, or networks
- Systems without Node.js, Chromium, git, or an accessible model backend
| - Users without a Hevy PRO subscription (API key required)
- Users who want to use the server without an API key
- Those needing delete workflows (Hevy API does not expose delete endpoints)
| - Simple static-page scraping where you don't want to depend on a third-party API and incur call costs
- Sites that explicitly disallow automated access (robots.txt)
|
|---|
| Required permissions | - Read and write access to the local state directory and SQLite databases
- Permission to run approved shell commands and perform some process operations
- Access to the configured Chromium browser, browser profile, and websites
- Network access to configured llama-server, cloud models, search providers, or HTTP endpoints
- Permissions required by external MCP servers whose tools are invoked
- Optional macOS Accessibility, Screen Recording, Automation, or Reminders permissions
| - Requires HEVY_API_KEY environment variable for Hevy API authentication
- Can create, update, and replace workouts, routines, folders, templates, and body measurements via tools
- Read operations can fetch workouts, routines, folders, templates, history, and user info
| - Requires a Firecrawl API key to call; cost and quota are governed by the Firecrawl account
- firecrawl_agent/firecrawl_interact perform automated browser interaction, which may trigger login or form-submission flows on the target site
|
|---|
| Risks and side effects | - Browser navigation, HTTP tools, cloud models, search providers, MCP, Telegram, update checks, and analytics can create network egress
- Shell commands and skills inherit the agent process environment and may access `.env` secrets
- Traces and `.env` under the state directory should be treated as sensitive; the project says redaction and environment filtering are not complete isolation
- Filesystem writes, patches, archive extraction, process termination, HTTP requests, and untrusted MCP tools are policy-gated, but approval errors can still cause harm
- The project is a developer preview, so commands, configuration, and behavior may change
| - API key can be misused if leaked; do not expose in URLs, logs, or screenshots
- Create operations may produce duplicates on retry; update operations replace existing records
- The server sends data to the Hevy API and may send telemetry to external services unless disabled
| - Bulk crawl/map tools can generate significant request volume against a target site — respect the site's rate limits and terms of service
- firecrawl_agent's interactive action chain is longer — define task boundaries clearly before running it to avoid accidentally triggering actions on a sensitive site
