Unmeasured means there is not enough evidence to decide. How these checks work

Inspect individual checks 22 recorded

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 104 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-06-18, serverInfo.name crawdar.

  • Pass
    Lists tools

    tools/list returned 21 tools.

  • Pass
    Current protocol

    Negotiated 2025-06-18. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 104 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 104 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    46 of 156 parameters have a description (29%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-08-26T18:07:10.102525Z, within 180 days.

  • Not measured
    Open-source licence

    No GitHub repository to ask about a licence.

Capabilities

Tools 21

browse_owner_demands

Browse 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.

Discovered
browse_service_providers

Read provider-declared capabilities, portfolio URLs, markets, and capacity. These are self-reported and do not imply a skill or performance endorsement.

Discovered
cancel_lead_search

Cancel a queued or running search job. Completed and failed jobs remain immutable.

Discovered
create_opportunity_workspace

Save a research thesis workspace and declared capabilities. This does not run research or establish demand. Use idempotencyKey to safely retry creation.

Discovered
create_owner_demand_draft

Create 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.

Discovered
explain_crawdar

Get result semantics, limits, interface URLs, and safe operating guidance. This tool does not consume a search.

Discovered
get_lead_search

Read job status or one cursor-paginated result page. Keep jobToken private and pass nextCursor back unchanged.

Discovered
get_opportunity_learning

Read 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.

Discovered
get_opportunity_workspace

Get the current workspace and revision before updating. Evidence, contradictory findings, manually recorded validation milestones, and monitor configuration remain private to the account.

Discovered
list_opportunity_workspaces

List research workspaces owned by your verified account. Requires an account-linked API key or signed-in identity; no guest access or public Atlas.

Discovered
match_demand_providers

Rank 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.

Discovered
refine_lead_search

Create a new private search job by changing the brief or criteria of a completed job. The original job stays unchanged.

Discovered
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.

Discovered
research_opportunity_workspace

Run 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 duplicate concurrent scans.

Discovered
retry_lead_search

Create a replacement job when a prior job failed or exceeded its execution window. The original job stays available for audit.

Discovered
sandbox_businesses

Return deterministic fictional businesses without consuming provider capacity. Use this to test schemas, clients, and agent loops.

Discovered
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.

Discovered
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.

Discovered
search_problem_graph

Read 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 workspaces are never included automatically. Contributions and owner reports are not independently verified facts or purchase intent.

Discovered
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.

Discovered
update_opportunity_workspace

Apply 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.
