EventCompletion MCP server

Which MCP servers are EventCompletion'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 namecom.eventcompletion/eventsverified in the MCP registry

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

On 2026-10-29 the server answered initialize and tools/list without a sign-in. First answer in 233 ms.

Should an agent connect itNot proven either way yet
  • Its tools do share a live progress page for a tournament or season, but not add a event's start and end dates to a calendar.
  • Checked on 5 of the 7 days it takes to judge reliability.

Once connected

  • For "share a live progress page for a tournament or season", the likely first call is register_agent.
  • create_event change data without a sign-in: anyone with the address can call them.
  • Parameters are untyped or undescribed in 2 of 5 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.

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

  • Tools that change data, on a server that answers without a sign-in: create_event

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 →

  • create_event

    Create a public progress page for an event (needs an API key whose contact e-mail is confirmed; max 10 per day). The event is unlisted: it is reachable by its URL but not featured in the catalogue or sitemap. Dates are inclusive calendar…

How to connect

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

      "type": "http",
      "url": "https://eventcompletion.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http eventcompletion https://eventcompletion.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://eventcompletion.com/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.
