FRESH MCP

FRESH provides shared URL freshness intelligence for AI agents, allowing them to decide whether to reuse cached knowledge or fetch a resource again. It returns REUSE, REFETCH, or UNKNOWN decisions based on privacy-safe shared change history, helping agents avoid unnecessary retrieval costs.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

90-day uptime

A lightweight connection check about every six hours, sampled on hosts with many listings. It shows the server answered, not that its tools work.

Too few checks for a percentage yet (2 of 2 answered).

30-day availability

Aggregated from read-only remote checks; this is not a tool-execution or security guarantee.

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 fresh-mcp https://fresh-api-production-c783.up.railway.app/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 fresh-mcp --url https://fresh-api-production-c783.up.railway.app/mcp

Cursor

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

Cursor configuration

{
  "mcpServers": {
    "fresh-mcp": {
      "url": "https://fresh-api-production-c783.up.railway.app/mcp"
    }
  }
}

Cline

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

Cline configuration

{
  "mcpServers": {
    "fresh-mcp": {
      "type": "streamableHttp",
      "url": "https://fresh-api-production-c783.up.railway.app/mcp",
      "disabled": false
    }
  }
}

VS Code

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

VS Code configuration

{
  "servers": {
    "fresh-mcp": {
      "type": "http",
      "url": "https://fresh-api-production-c783.up.railway.app/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 fresh-mcp https://fresh-api-production-c783.up.railway.app/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.

Claude Desktop configuration

https://fresh-api-production-c783.up.railway.app/mcp

Windsurf

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

Windsurf configuration

{
  "mcpServers": {
    "fresh-mcp": {
      "serverUrl": "https://fresh-api-production-c783.up.railway.app/mcp"
    }
  }
}
