| Best for | - AI assistants that need real-time web search
- Users needing Perplexity Agent API research and reasoning capabilities
- Developers using MCP-compatible client tools
| - 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
| - Q&A and research scenarios that need real-time, clean web content
- Users with an existing Exa account who want a zero-deployment remote option
|
|---|
| Not for | - Local tasks that do not need internet or an external API
- Environments without a Perplexity API key
- Immediate-use scenarios that cannot wait for research runs lasting several minutes
| - 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)
| - Scenarios requiring a strict allowlist of search sources that can't use a third-party search service
- Budget-sensitive, high-volume search scenarios (remote/API calls may incur cost)
|
|---|
| Required permissions | - Requires access to PERPLEXITY_API_KEY
- Requires network access to the Perplexity API and the internet
- HTTP deployments may require network binding and host, origin, and port configuration
| - 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
| - Requires an Exa API key for full functionality; OAuth login is optional in remote mode
- web_fetch_exa retrieves content from a specified URL; agent_run performs multi-step autonomous actions and needs the user to have clear expectations of Agent behavior
|
|---|
| Risks and side effects | - The API key must be configured through the environment and should not be exposed.
- Setting BIND_ADDRESS to 0.0.0.0 exposes the HTTP service on all network interfaces.
- Setting ALLOWED_ORIGINS to * permits cross-origin browser requests from any origin.
- Deep research runs may take minutes and may require a higher timeout.
| - 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
| - The API key should be stored carefully — avoid leaving it in plaintext in client config files on untrusted machines
- agent_run is a multi-step autonomous tool with a longer action chain — try it on low-risk tasks first
