| Best for | - Researchers and biomedical agents needing programmatic PubMed or Europe PMC access
- Workflows requiring structured literature metadata, full text, and citation output
- Literature-management tasks involving DOI, PMID, and PMCID identifiers
| - 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 seeking searches across non-biomedical databases
- Workflows requiring guaranteed full-text availability for every article
- Users that need this server to be treated as an official PubMed or NCBI server
| - 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 | - The server needs access to NCBI services; Europe PMC access is needed when Europe PMC features are enabled.
- Full-text fallback through Unpaywall requires UNPAYWALL_EMAIL and access to Unpaywall.
- API keys and contact emails are optional; NCBI_API_KEY can increase the NCBI rate limit.
- Streamable HTTP deployments can use none, jwt, or oauth authentication; the default is none.
| - 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 | - Full-text retrieval depends on PMC, Europe PMC, or legal open-access sources and may return unavailable or truncated results.
- Unpaywall results may include best-effort warnings and may be returned as HTML Markdown or PDF text.
- The source does not provide further details about authentication or availability of the public hosted instance.
- NCBI and Europe PMC requests are affected by rate limits, timeouts, and retry settings.
| - 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
