TenderSpotter MCP

An MCP server operated by TenderSpotter that allows AI assistants to search Dutch public tenders from TenderNed, view tender details and documents, check awards and competitors, and find expected re-tenders. It provides read-only access to enriched tender data, updated four times daily, supporting integration with Claude, ChatGPT, and other agents via OAuth or API keys.

Endpoint and access

OAuth sign-in: the first time you connect, your client opens the vendor's own authorization prompt in a browser.

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 tenderspotter-mcp https://www.tenderspotter.nl/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 tenderspotter-mcp --url https://www.tenderspotter.nl/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable tenderspotter-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "tenderspotter-mcp": {
      "url": "https://www.tenderspotter.nl/api/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "tenderspotter-mcp": {
      "type": "streamableHttp",
      "url": "https://www.tenderspotter.nl/api/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start tenderspotter-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "tenderspotter-mcp": {
      "type": "http",
      "url": "https://www.tenderspotter.nl/api/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 tenderspotter-mcp https://www.tenderspotter.nl/api/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
{
  "mcpServers": {
    "tenderspotter-mcp": {
      "serverUrl": "https://www.tenderspotter.nl/api/mcp"
