Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
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.

Tool inventory
Tools (3)
🟢search(query, kind, limit)
Full-text search over tools (topics) and their sources. Matches names, roles, regions, detection signals (files, dependencies, env vars), source titles and URLs. Every word must match, as a prefix.
Input Schema
{
"type": "object",
"properties": {
"query": {
"type": "string",
"minLength": 1,
"maxLength": 200,
"description": "Words to search for, e.g. \"database\", \"vercel mcp\" or \"turbo.json\""
},
"kind": {
"description": "Only return sources of this kind",
"type": "string",
"enum": [
"llms",
"full",
"docs",
"mcp",
"skill",
"rules",
"guide"
]
},
"limit": {
"description": "Maximum number of topics, default 10",
"type": "integer",
"minimum": 1,
"maximum": 50
}
},
"required": [
"query"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_topic(id)
All sources (llms.txt, docs, MCP servers, skills, rules), detection signals and the role of one tool, by id such as `vercel`, `nextjs` or `drizzle`.
Input Schema
{
"type": "object",
"properties": {
"id": {
"type": "string",
"minLength": 1,
"description": "Topic id, as returned by search or list_topics"
}
},
"required": [
"id"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢list_topics(region)
Every tool in the catalog with its id, name, role and region, without sources. Use it to find candidates per role, then get_topic and their llms.txt sources to compare them.
Input Schema
{
"type": "object",
"properties": {
"region": {
"description": "Only this region id, e.g. cloud, frameworks, standards or clis",
"type": "string"
}
},
