TendFeed MCP server

Which MCP servers are TendFeed'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 nameeu.tendfeed/tendfeedverified in the MCP registry

The registry name sits under tendfeed.eu. 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 157 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: check how many bidders compete before writing a proposal; decide whether a tender is worth bidding on.
  • Checked on 2 of the 7 days it takes to judge reliability.

Once connected

  • Parameters are untyped or undescribed in 1 of 4 tools: check arguments before calling.

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.

What an agent can do with it

  • can do · check how many bidders compete before writing a proposal
  • not sure · compare competition density by sector and country
  • can do · decide whether a tender is worth bidding on

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 →

  • find_low_competition_lanes

    Rank CPV sector "lanes" by OBSERVED competition density from the full corpus of 530,000 real EU awards: median bidders, single-bidder share, bid-rate, median value, beachhead score. Answers "where is competition thinnest right now". It…

  • find_winnable_lanes

    DEPRECATED — use find_low_competition_lanes instead; this alias behaves identically and stays available for existing clients. The old name wrongly implied a win forecast: TendFeed measures observed competition density, not the probability…

  • search_tenders

    Open EU tenders with a bid/no-bid verdict (Worth-It score, reason, competition density, price corridor where robust, deadline, SME-fit). Filter by sector (CPV division), country (NUTS), SME-only, min score. Guests (no key) get the…

How to connect

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

{
  "mcpServers": {
    "tendfeed": {
      "type": "http",
      "url": "https://tendfeed.eu/api/mcp/tendfeed"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http tendfeed https://tendfeed.eu/api/mcp/tendfeed

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://tendfeed.eu/api/mcp/tendfeed 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.
