search_events — Search flea markets in Germany
Advertised by the server during the last successful anonymous check.
Advertised read-only

Search German flea markets (Flohmarkt, Trödelmarkt, Hofflohmarkt, Kinderflohmarkt, Antik- und Sammlermarkt) from the public my-flohmarkt.de catalogue. Filter by free text, by city name or postal code (PLZ) via the city argument, by date range, or by radius around a coordinate. Radius searches require lat, lng, and radiusKm together (max 100 km). Each hit carries title, date, start and end time, PLZ, city, coordinates, market type and the public event URL. Returns at most 50 results plus a dataAsOf timestamp.

get_event — Get flea market details
Advertised by the server during the last successful anonymous check.
Advertised read-only

Get the full public details of one German flea market by its UUID, as returned in the id field of search_events or recently_updated_events: description text, street address, date and opening times, market type and topics, entrance fee and seller stand fee, stand sizes and table rental, whether sellers can still sign up, and the public my-flohmarkt.de event URL. Use it when a search hit is not enough to answer about price, address or what is sold. Unknown or non-public UUIDs return not_found.

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).

  1. 2026-11-06: 1 of 1 checks answered
  2. 2026-11-07: 1 of 1 checks answered

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 myflohmarkt-mcp https://mcp.my-flohmarkt.de/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 myflohmarkt-mcp --url https://mcp.my-flohmarkt.de/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable myflohmarkt-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "myflohmarkt-mcp": {
      "url": "https://mcp.my-flohmarkt.de/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "myflohmarkt-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.my-flohmarkt.de/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start myflohmarkt-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "myflohmarkt-mcp": {
      "type": "http",
      "url": "https://mcp.my-flohmarkt.de/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 myflohmarkt-mcp https://mcp.my-flohmarkt.de/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://mcp.my-flohmarkt.de/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": {
    "myflohmarkt-mcp": {
      "serverUrl": "https://mcp.my-flohmarkt.de/mcp"
    }
  }
}
