What datasets_x_users_facets does on Crawlora
AI agents call datasets_x_users_facets to retrieve information from Crawlora without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
q | string | — | Full-text query over username, name, bio and location, max 256 characters |
sort | string | — | Sort enum: relevance, followers_desc, followers_asc, crawled_at_desc, crawled_at_asc, created_at_desc, created_at_asc |
facet | string | Yes | Facet enum: is_blue_verified, has_bio, has_external_url, source_tier |
has_bio | boolean | — | Filter by a non-empty profile bio |
username | string | — | Exact username filter (case-insensitive), max 128 characters |
max_ratio | number | — | Maximum follower-to-following ratio |
min_ratio | number | — | Minimum follower-to-following ratio |
source_tier | string | — | Exact filter for which seed tier discovered this account |
crawled_after | string | — | Records last refreshed on or after this date (RFC3339 or YYYY-MM-DD) |
created_after | string | — | Accounts created on or after this date (RFC3339 or YYYY-MM-DD) |
max_followers | integer | — | Maximum follower count |

Why datasets_x_users_facets is rated Low
This tool queries a dataset to return faceted aggregation statistics (counts grouped by enum values like is_blue_verified, has_bio, etc.). It is a retrieval/analytics operation with no capability to modify, delete, or execute code. The low severity reflects that exposing aggregated statistics about a dataset poses minimal risk compared to write, execute, or destructive operations.
From the tool's definition Tool description states it 'Returns terms aggregation counts' and 'Facet the X users dataset' — these are read-only operations that retrieve and aggregate existing data without modification or side effects.

Attacks that exploit this kind of access
The rule that runs datasets_x_users_facets safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Crawlora, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For datasets_x_users_facets, this is the rule to start with:
datasets_x_users_facets is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Crawlora, apply this rule, and every datasets_x_users_facets call is checked against it from then on.
Questions about datasets_x_users_facets
Facet the X users dataset. Returns terms aggregation counts for the X users dataset. Facet enum: is_blue_verified, has_bio, has_external_url, source_tier. It is categorised as a Read tool in the Crawlora MCP Server, which means it retrieves data without modifying state.
datasets_x_users_facets accepts 12 parameters: q, sort, facet, has_bio, username, max_ratio, min_ratio, source_tier, crawled_after, created_after, max_followers, min_followers. Required: facet. The full parameter table on this page comes from the server's own tool schema.
Register the Crawlora MCP server in PolicyLayer and add a rule for datasets_x_users_facets: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Crawlora. Nothing to install.
datasets_x_users_facets is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the datasets_x_users_facets rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for datasets_x_users_facets. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
datasets_x_users_facets is provided by the Crawlora MCP server (crawlora-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
