Crawdar Business Research is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
scan_review_pain_pointsScan 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 configureresearch_businessesUse 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.search_businessesUse 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.sandbox_businessesReturn deterministic fictional businesses without consuming provider capacity. Use this to test schemas, clients, and agent loops.start_lead_searchUse 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.get_lead_searchRead job status or one cursor-paginated result page. Keep jobToken private and pass nextCursor back unchanged.refine_lead_searchCreate a new private search job by changing the brief or criteria of a completed job. The original job stays unchanged.retry_lead_searchCreate a replacement job when a prior job failed or exceeded its execution window. The original job stays available for audit.cancel_lead_searchCancel a queued or running search job. Completed and failed jobs remain immutable.explain_crawdarGet result semantics, limits, interface URLs, and safe operating guidance. This tool does not consume a search.list_opportunity_workspacesList research workspaces owned by your verified account. Requires an account-linked API key or signed-in identity; no guest access or public Atlas.create_opportunity_workspaceSave a research thesis workspace and declared capabilities. This does not run research or establish demand. Use idempotencyKey to safely retry creation.get_opportunity_workspaceGet the current workspace and revision before updating. Evidence, contradictory findings, manually recorded validation milestones, and monitor configuration remain private to the account.update_opportunity_workspaceApply one validated command with the latest revision. A 409 means re-read before retrying. Public signals never establish payment or purchase intent; commercial milestones require separately supplied attributable evidence. Does not contact businesses or execute delivery.research_opportunity_workspaceRun a bounded public review scan of up to three businesses and retain sourced findings in your private workspace. Requires current revision. Sampled complaints are investigation leads, not owner-confirmed needs or purchase proof. Uses normal provider limits; do not launch duplicasearch_problem_graphRead Crawdar editorial research, explicitly contributed observations, and website-control-confirmed owner demand across markets. Editorial research does not mean the featured business joined or confirmed a problem. Includes source URLs, dates, support and contradiction. Private wbrowse_owner_demandsBrowse public business requests with current website-control proof. A posted request is owner-reported need, not a funded contract, verified budget, or permission to contact outside the application flow.browse_service_providersRead provider-declared capabilities, portfolio URLs, markets, and capacity. These are self-reported and do not imply a skill or performance endorsement.match_demand_providersRank one page of up to 50 published providers by declared skill labels and market fit. Public consented outcome context remains separate from provider ratings. Use nextCursor for more candidates; missing data is unknown.get_opportunity_learningRead your private evidence funnel and failure feedback plus sufficiently diverse, jointly consented public outcome aggregates. Requires verified account identity or linked API key. Rates describe recorded cohorts and do not prove causal effectiveness or future results.create_owner_demand_draftCreate a private draft request. Publishing is a separate owner-controlled action requiring website control and explicit review of public fields. This tool never publishes, contacts providers, creates a contract, or moves money.https://crawdar.com/api/mcpNot in Muse's Connectors list yet, but Muse can still use it.
