Whose server it is
  • Registry namenet.fidren/counterpartyverified in the MCP registry

The registry name sits under fidren.net. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

Should an agent connect itNot proven either way yet
  • Its tools do check a counterparty before an agent sends money, but not set the maximum amount an agent may risk per payment.
  • Checked on 1 of the 7 days it takes to judge reliability.

Once connected

  • For "check a counterparty before an agent sends money", the likely first call is fidren_check_counterparty.

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 (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). 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 →

  • fidren_check_counterparty

    Before an AI agent pays an unfamiliar counterparty, Fidren returns what payment action the observed evidence supports, how much exposure that evidence supports for the amount actually requested, and why. Same counterparty, same evidence…

How to connect

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

{
  "mcpServers": {
    "counterparty": {
      "type": "http",
      "url": "https://api.fidren.net/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http fidren https://api.fidren.net/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://api.fidren.net/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.
