# ZVG Einfach (remote · mcp.zvg-einfach.de) German foreclosure auctions (Zwangsversteigerungen): search, details, AI analysis, statistics. - Trust score: 72/100 (medium) - Change this week: +4 - Registry status: active - Liveness: live - Owner verified: no - Last scored: 2026-11-05 ## Components - remote · `mcp.zvg-einfach.de`: 72/100 (this document), [markdown](https://verifymcp.io/servers/de-zvg-einfach-zvg-einfach/mcp.md), [page](https://verifymcp.io/servers/de-zvg-einfach-zvg-einfach/mcp) ## Channel facts - Endpoint: `https://mcp.zvg-einfach.de/mcp` - Transports: `streamable-http` - Auth: `required (not validated)` - Version: `1.0.0` ## Trust breakdown How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-11-05. - **Endpoint Security**: 71/100 - The endpoint's TLS certificate is valid, in date, and uses a strong key. - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token. - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. - HSTS check failed: the Strict-Transport-Security header is absent. - DNSSEC check failed: this domain isn't protected by DNSSEC. - **Transport & Reachability**: 100/100 - Verified streamable-http transport via a live MCP handshake. - **Schema Quality & AI Usability**: 66/100 - AI-judged instruction clarity (good). - Context-footprint check failed: tool/resource definitions use about 900 tokens (~150/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 40/100 - Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses. - **Tool Coverage**: 71/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 0% of tool parameters carry a description. - Structured output schemas are declared (100% of tools); any adoption earns full credit. - **Tool Safety**: 100/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation. - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it. - **Capabilities**: 100/100 - Implements a current MCP spec version (2026-07-28). ## Install ### How do I install the ZVG Einfach MCP server? ZVG Einfach is a hosted endpoint at https://mcp.zvg-einfach.de/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation. ### Claude ```bash claude mcp add --transport http de-zvg-einfach-zvg-einfach 'https://mcp.zvg-einfach.de/mcp' ``` ### Cursor ```json { "mcpServers": { "de-zvg-einfach-zvg-einfach": { "url": "https://mcp.zvg-einfach.de/mcp" } } } ``` ### VS Code ```json { "servers": { "de-zvg-einfach-zvg-einfach": { "type": "http", "url": "https://mcp.zvg-einfach.de/mcp" } } } ``` ### Codex ```toml [mcp_servers.de-zvg-einfach-zvg-einfach] url = "https://mcp.zvg-einfach.de/mcp" ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "de-zvg-einfach-zvg-einfach": { "type": "remote", "url": "https://mcp.zvg-einfach.de/mcp", "enabled": true } } } ``` ### OpenClaw ```bash openclaw mcp add de-zvg-einfach-zvg-einfach --url 'https://mcp.zvg-einfach.de/mcp' --transport streamable-http ``` ### Hermes ```yaml mcp_servers: de-zvg-einfach-zvg-einfach: url: "https://mcp.zvg-einfach.de/mcp" ``` ### Netclaw ```json { "McpServers": { "de-zvg-einfach-zvg-einfach": { "Transport": "http", "Url": "https://mcp.zvg-einfach.de/mcp" } } } ``` ### Vellum ```bash assistant mcp add de-zvg-einfach-zvg-einfach -t streamable-http -u 'https://mcp.zvg-einfach.de/mcp' ``` ### Other ```json { "mcpServers": { "de-zvg-einfach-zvg-einfach": { "type": "http", "url": "https://mcp.zvg-einfach.de/mcp" } } } ``` The mcpServers block is a cross-client convention.

ZVG Einfach is an MCP server listed in the public MCP registry as de.zvg-einfach/zvg-einfach. German foreclosure auctions (Zwangsversteigerungen): search, details, AI analysis, statistics. This page covers its hosted endpoint (https://mcp.zvg-einfach.de/mcp). ### Is the ZVG Einfach MCP server safe to use? ZVG Einfach scores 72 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm. ### What tools does the ZVG Einfach MCP server expose? ZVG Einfach exposes 6 tools: search_auctions, get_auction, list_federal_states, list_courts_in_state, get_market_statistics, get_filter_options. Their descriptions and schemas cost roughly 804 tokens of context every time the server is loaded. ### Does the ZVG Einfach MCP server require authentication? Yes. ZVG Einfach asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything. ### Is the ZVG Einfach MCP server still maintained? ZVG Einfach is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced. ### What did VerifyMCP test on the ZVG Einfach MCP server? VerifyMCP ran 12 checks on ZVG Einfach, covering TLS certificate, Authorization, HSTS header, DNSSEC and 8 more. One item could not be completed, a gap on our side rather than a finding about ZVG Einfach: HTTPS. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out. ## Links - Remote endpoint: https://mcp.zvg-einfach.de/mcp - Authorisation metadata: https://mcp.zvg-einfach.de/.well-known/oauth-protected-resource/mcp - Website: https://zvg-einfach.de/fuer-unternehmen/mcp-docs - Changelog RSS feed: https://verifymcp.io/servers/de-zvg-einfach-zvg-einfach/mcp.xml - Changelog JSON feed: https://verifymcp.io/servers/de-zvg-einfach-zvg-einfach/mcp/changelog.json - Trust report (JSON): https://verifymcp.io/servers/de-zvg-einfach-zvg-einfach/mcp.json - HTML version of this page: https://verifymcp.io/servers/de-zvg-einfach-zvg-einfach/mcp
