Freshness Validator MCP

Scores how fresh an AI agent's context is and flags content that changed at its source. Agents register public source URLs, send context, and receive a freshness score (0-100), a stale flag, flagged issues, and suggestions. Billing is per call from prepaid credits or pay-per-call.

Endpoint and access

Server-provided instructions

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

Freshness Validator scores how fresh a piece of context is (validate) and monitors registered source pages for changes (register_source). Calls are billed from the myuiaf wallet. Docs: https://myuiaf.com/docs

validate — Check context freshness

Advertised by the server during the last successful anonymous check.

Open-world

Checks how fresh a piece of context is. Returns a score from 0 to 100, a stale flag (score below 70), flagged issues, and suggestions. Change detection and content matching apply when the source_url has been registered with register_source. Billed per call from the prepaid myuiaf wallet ($0.015-$0.03). API docs: https://myuiaf.com/docs

register_source — Monitor a source page

Advertised by the server during the last successful anonymous check.

Open-world

Registers a public https URL for ongoing freshness monitoring. The page is fetched once immediately as a baseline. Costs twice the per-call rate; registering the same URL again only updates its check frequency. API docs: https://myuiaf.com/docs

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 freshness-validator-mcp https://api.myuiaf.com/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 freshness-validator-mcp --url https://api.myuiaf.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable freshness-validator-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "freshness-validator-mcp": {
      "url": "https://api.myuiaf.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "freshness-validator-mcp": {
      "type": "streamableHttp",
      "url": "https://api.myuiaf.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start freshness-validator-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "freshness-validator-mcp": {
      "type": "http",
      "url": "https://api.myuiaf.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http freshness-validator-mcp https://api.myuiaf.com/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration
