Best for
  • Claude Code users who want their agent to stop repeating mistakes
  • Developers who want honest measurement of memory effectiveness
  • Privacy-conscious users requiring local storage
  • Teams adopting structured memory layers (episodic, semantic, procedural, etc.)
  • 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
  • Scenarios requiring real-time or high-throughput memory retrieval
  • Users wanting fully automatic memory management without manual session loop
  • Projects needing cloud sync or multi-user collaboration
  • Users requiring advanced retrieval performance like BM25 indexing
  • 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 local filesystem (default path ~/.agent-recall/)
  • Execute local commands (e.g., CLI tools)
  • Optional: OpenAI API usage if OPENAI_API_KEY is set for vector search
  • Optional: Supabase mirror for remote sync
  • 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
  • Memory content may contain sensitive information; ensure access control despite local storage
  • The measurement instrument may produce misleading data (e.g., defaulted to "heeded" bias); interpret cautiously
  • The automatic session loop requires user compliance with session start/end protocols; otherwise memory may be incomplete
  • Experimental components (e.g., dream consolidation, recurrence harness) may be unstable
  • Dependency on npm package execution poses supply-chain risk (verify source)
  • 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
