ReLaEx – Engineers MCP server

Which MCP servers are ReLaEx – Engineers's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namede.relaex-engineers/boring-apiverified in the MCP registry

The registry name sits under relaex-engineers.de. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-26 the server answered initialize and tools/list without a sign-in. First answer in 486 ms.

Should an agent connect itSkip it
  • Its tools do none of the product's use cases we checked: redesign existing circuit boards for retrofit projects; review PCB layouts before manufacturing and list changes; develop new or revised schematics for electronics hardware.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • supplier_compare

    Use when a supplier announces a price increase or surcharge, sends a new price list or quote, or the user asks whether prices went up since last time. Compares the old basis with the new list per SKU. The old side can be an earlier price…

  • documents_tables

    Extracts tables from a text-based PDF (price list, data sheet, report; up to 20 MiB, 60 pages) with page, bounding box and a quality level per table. Detects header rows, titles and footnotes and merges tables continued across pages only…

  • merchant_validate

    Checks a product feed or catalog export for Google Merchant Center, Shopify or Meta (Facebook/Instagram) before upload. Validates CSV, TSV or XLSX against the platform profile: required fields, allowed values (with a hint for localized…

  • schema_normalize

    Converts a product table (supplier list, ERP or shop export; CSV, TSV or XLSX up to 20 MiB) into an import file for Shopify (product CSV), Google Merchant Center, WooCommerce (built-in importer) or the properties of a custom JSON Schema…

  • table_diff

    Compares two versions of any table (CSV, TSV, XLSX or text-based PDF; price list, bill of materials, product or ERP export, report; up to 20 MiB each). Finds the key column (or uses the given one), matches rows and lists added, removed…

  • datasheet_compare

    Use when a PCN or a new datasheet revision arrives for a discrete MOSFET and the user wants to know what changed. Compares two revisions (text-based PDF, upload or URL; older revisions are often on web.archive.org) and reports changed…

  • datasheet_changes

    Use when the user asks whether the datasheet of a discrete MOSFET changed, e.g. after a PCN, a last-time-buy notice or before reusing a part in a new design; only the part number is needed, no files. Finds the current datasheet at the…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "boring-api": {
      "type": "http",
      "url": "https://api.relaex-engineers.de/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http relaex-engineers https://api.relaex-engineers.de/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://api.relaex-engineers.de/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
