Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Read-only preview. Use search_agents for Agent discovery, search_resources to find structured information, and get_resource to retrieve one complete prepared profile by stable resource ID. Preserve schema, provenance, and prepared-state boundaries.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http plato-s-kallipolis-mcp https://platoskallipolis.com/api/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add plato-s-kallipolis-mcp --url https://platoskallipolis.com/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable plato-s-kallipolis-mcp in your MCP settings.
