Plato's Kallipolis
Read-only MCP tools for AI agent discovery, structured resources, and NIULAI information.
Should I use this
Quality & Safety
A
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
~1,212Tokens (tool definitions)
~1.7 KBTypical response size
Moderate attention impact (0.95% of 128k context)
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.

Search the public agent registry by capability and protocol. Preview data only.

}🟢search_resources(category, q, limit, cursor)
Search 350 prepared structured resource profiles by category, keyword or declared source hostname without contacting external providers.

"description": "Up to 8 whitespace-separated terms within 100 UTF-16 code units including outer whitespace; all terms must match literal case-insensitive substrings across public fields, declared publisher names or declared source hosts, in any order. Example: World Bank public, or worldbank.org public. Hostname matches include label-boundary subdomains; no full URLs, credentials, control characters, stemming or model inference. Ordering: exact resource ID first, then every term matched as a whole word in the title or a declared publisher name, or as a declared source host, then remaining substring matches; ties use stable resource ID order. Ranking is not a quality or ownership assertion."
