Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (4)
🟢fetch(url)
Get clean, readable text from a web page — boilerplate, navigation, and ads stripped — so you can work with the actual content. Returns the text plus title, content-type, HTTP status, and length.
Input Schema
{
"type": "object",
"properties": {
"url": {
"title": "Url",
"type": "string"
}
},
"required": [
"url"
],
"title": "fetchArguments"
}🟢check_link(url)
Is this URL live right now? Returns HTTP status, the redirect chain, final URL, and round-trip latency in milliseconds.
Input Schema
{
"type": "object",
"properties": {
"url": {
"title": "Url",
"type": "string"
}
},
"required": [
"url"
],
"title": "check_linkArguments"
}🟡check_change(url)
Did this web page change since the last time it was checked? Hash-based change detection. First check reports 'new'; later checks report 'changed' or 'unchanged'.
Input Schema
{
"type": "object",
"properties": {
"url": {
"title": "Url",
"type": "string"
}
},
"required": [
"url"
],
"title": "check_changeArguments"
}⚪verify(claim, source_url)
Does this source URL support a given claim? Returns a confidence score, matched terms, and the best supporting excerpt. Heuristic term-overlap — not semantic fact-checking.
Input Schema
{
"type": "object",
"properties": {
"claim": {
"title": "Claim",
"type": "string"
},
"source_url": {
"title": "Source Url",
"type": "string"
}
},
"required": [
"claim",
"source_url"
],
"title": "verifyArguments"
