Best for
  • Users who want self-hosted search infrastructure
  • Teams with an existing SearXNG instance and privacy requirements
  • MCP clients that need paginated search and URL reading
  • 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 without an accessible SearXNG instance
  • Users seeking a native SearXNG plugin installation
  • Workflows that require reading PDFs, media, archives, or other binary downloads
  • 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
  • Requires access to the configured SEARXNG_URL, which the manifest marks as required and secret.
  • May use AUTH_USERNAME and AUTH_PASSWORD for legacy global SearXNG Basic Auth.
  • Search queries are passed to external search services, and web_url_read makes requests to user-specified URLs.
  • 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
  • Privacy depends on the connected SearXNG instance and its configuration.
  • Search queries may be passed to external services used by SearXNG.
  • URL reading creates outbound requests; private or internal URLs and redirects are blocked by default, but network deployments should still enable and configure hardening.
  • HTML fallback depends on the instance's page structure and may return fewer results without relevance scores or engine names.
  • 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
