SameDayDesk Page Change MCP

A free MCP server that compares two held JSON page observations to detect changes. It does not fetch URLs, take payment, or schedule observations, serving as a local diff tool for previously extracted data.

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.

Server-provided instructions

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

Compare two JSON page observations the caller already holds. The only tool is compare_page_observations. Do not fetch URLs, extract remote pages, schedule a later observation, or take payment.

Compare two already-held extract-batch JSON artifacts. charged is false. Not a paid SKU. Does not fetch, pay, or schedule a second observation. Compare only the explicitly selected data keys present on both matched rows. Missing keys are coverage unknown, not deletions; explicit null is a present value. Unselected metadata is not a content delta. SYNTHETIC offline construction example only. No URL fetch, payment, receipt, observation or freshness is evidenced.

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 samedaydesk-page-change-mcp https://agents.samedaydesk.com/mcp/page-change

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 samedaydesk-page-change-mcp --url https://agents.samedaydesk.com/mcp/page-change

Cursor

Merge this server into .cursor/mcp.json in your project, then enable samedaydesk-page-change-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "samedaydesk-page-change-mcp": {
      "url": "https://agents.samedaydesk.com/mcp/page-change"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "samedaydesk-page-change-mcp": {
      "type": "streamableHttp",
      "url": "https://agents.samedaydesk.com/mcp/page-change",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start samedaydesk-page-change-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "samedaydesk-page-change-mcp": {
      "type": "http",
      "url": "https://agents.samedaydesk.com/mcp/page-change"
    }
  }
}

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 samedaydesk-page-change-mcp https://agents.samedaydesk.com/mcp/page-change

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "samedaydesk-page-change-mcp": {
      "url": "https://agents.samedaydesk.com/mcp/page-change"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "samedaydesk-page-change-mcp": {
      "serverUrl": "https://agents.samedaydesk.com/mcp/page-change"
    }
  }
}
