websets-mcp-server

Create and manage collections of companies, people, and papers, automatically discovering and verifying relevant entities. Enrich items with custom fields like CEO name, funding amount, or company stage, and inspect detailed results. Schedule recurring searches to keep collections fresh and catch new additions.

Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

cancel_enrichment

Cancel a running enrichment operation. Only enrichments with status 'running' can be canceled; enrichments still in 'pending' status are unaffected.

cancel_search

Cancel a running search operation. This will stop the search from finding more items.

create_enrichment

Create a new enrichment for a webset. Enrichments automatically extract custom data from each item using AI agents (e.g., 'company revenue', 'CEO name', 'funding amount'). IMPORTANT PARAMETER FORMATS: - options (when format is "options"): MUST be array of objects like [{label: "..."}] (NOT array of

create_import

Create a new import to upload your own data (CSV) into Websets. Imports can be used for enrichment, scoped searches, or excluding known results. Returns an uploadUrl where you can PUT your CSV file. Example call: { "format": "csv", "size": 1024, "count": 100, "entity": {"type": "company"},

create_search

Create a new search to find and add items to a webset. The search will discover entities matching your query and criteria. IMPORTANT PARAMETER FORMATS: - entity: MUST be an object like {type: "company"} (NOT a string). For "custom" type, include description: {type: "custom", description: "SaaS tool

create_webhook

Create a webhook to receive real-time HTTP callbacks when events occur in your websets. Example call: { "url": "https://example.com/webhook", "events": ["webset.search.completed", "webset.enrichment.completed"] }

create_webset

Create a new Webset collection. Websets are collections of web entities (companies, people, papers) that can be automatically searched, verified, and enriched with custom data. IMPORTANT PARAMETER FORMATS: - searchCriteria: MUST be array of objects like [{description: "..."}] (NOT array of strings)

delete_webhook

Delete a webhook. The webhook stops receiving notifications immediately and cannot be recovered.

delete_webset

Delete a webset and all its items. This action is permanent and cannot be undone.

get_enrichment

Get details about a specific enrichment, including its status and progress.

get_import

Get details about a specific import, including its status, upload URL, and processing progress.

get_item

Get a specific item from a webset by its ID. Returns detailed information about the item including all enrichment data.

get_search

Get details about a specific search, including its status, progress, and results found.

get_webhook

Get details about a specific webhook. The webhook secret is not returned here for security — it is only shown when the webhook is first created.

get_webset

Get details about a specific webset by ID or externalId. Returns full webset information including status, searches, enrichments, imports, and metadata. REQUIRED: You must pass the "id" parameter. Use the webset ID returned from create_webset (e.g. "ws_abc123") or an externalId you assigned. TIP:

list_events

List system events with optional filtering. Events track all state changes across websets, searches, enrichments, and webhooks.

list_imports

List all imports. Returns a paginated list of imports with their status and metadata.

list_webset_items

List all items in a webset. Returns entities (companies, people, papers) that have been discovered and verified in the collection.

list_webhooks

List all webhooks in your account. Returns a paginated list of webhooks with their URL, events, status, and metadata.

list_websets

List all websets in your account. Returns a paginated list of webset collections with their current status, searches, enrichments, imports, and metadata.

preview_webset

Preview how a search query will be interpreted before creating a webset. Returns the detected entity type, generated search criteria, and suggested enrichment columns. Useful for understanding what a query will produce before committing.

update_webhook

Update a webhook's URL, events, or metadata. Changes take effect immediately. The webhook keeps its current status (active/inactive) when updated.

update_webset

Update a webset's title and/or metadata.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

23/23 tools missing one or more hints — cancel_enrichment (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cancel_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create_enrichment (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +20 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool test coverage

Only 2/23 tools referenced in tests (9%)

Write tests that reference each tool by name so every tool has at least one test.

Production dependencies are patched

0 critical, 11 high severity in production deps — axios@1.12.2 (high), axios@1.12.2 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Dev dependencies

1 critical/high in dev-only deps (does not ship to users)

Upgrade dev dependencies when convenient.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
