Available tools 10

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

businesses
search_businesses
Use for a quick synchronous search when target, geography, and qualification fields are already structured. Use research_businesses for a plain-language brief, or start_lead_search for durable asynchronous work.
cancel
cancel_lead_search
Cancel a queued or running search job. Completed and failed jobs remain immutable.
explain
explain_crawdar
Get result semantics, limits, interface URLs, and safe operating guidance. This tool does not consume a search.
lead
get_lead_search
Read job status or one cursor-paginated result page. Keep jobToken private and pass nextCursor back unchanged.
refine
refine_lead_search
Create a new private search job by changing the brief or criteria of a completed job. The original job stays unchanged.
research
research_businesses
Use for a quick synchronous search when the user supplies one natural-language brief and can wait for results in the current tool call. For durable progress, retry, export, or large agent workflows, use start_lead_search instead.
retry
retry_lead_search
Create a replacement job when a prior job failed or exceeded its execution window. The original job stays available for audit.
sandbox
sandbox_businesses
Return deterministic fictional businesses without consuming provider capacity. Use this to test schemas, clients, and agent loops.
scan
scan_review_pain_points
Scan a named business or discover up to three businesses for recent recurring complaints. Returns individually sourced reviews and possible technical solutions. Coverage is sampled; unavailable reviews never mean no problems. Five scans per day. Google reviews require a configured provider.
start
start_lead_search
Use for the recommended durable asynchronous workflow. Creates a private queued search job and returns a job id plus jobToken for progress polling, cursor paging, refinement, retry, cancellation, and CSV or JSON export.

Crawdar Business Research — questions

Answers built from our own checks of this server.

What can Crawdar Business Research do?
It exposes 10 tools, read directly from the server on our last check. Among them: cancel_lead_search, explain_crawdar, get_lead_search, refine_lead_search, research_businesses, retry_lead_search and 4 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Crawdar Business Research working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 731 ms. The bar chart above shows every period we have measured.
How do I connect Crawdar Business Research?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Crawdar Business Research need an API key?
No. Crawdar Business Research completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Crawdar Business Research?
It answers our handshake in 731 ms on average, which is faster than 13% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
