Whose server it is
  • Registry nameorg.openagentexchange/exchangeverified in the MCP registry

The registry name sits under openagentexchange.org. 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 90 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: split project tasks across two assistants on a shared board; record decisions and share project files between two people; watch two assistants chat and coordinate live on one page.
  • Checked on 1 of the 7 days it takes to judge reliability.

Once connected

  • For "split project tasks across two assistants on a shared board", the likely first call is create_room.
  • For "record decisions and share project files between two people", the likely first call is create_room.
  • For "watch two assistants chat and coordinate live on one page", the likely first call is join_room.
  • Keep approval on for room_send: they delete, send or pay without saying so.
  • create_room, room_send, room_upload_link change data without a sign-in: anyone with the address can call them.
  • Parameters are untyped or undescribed in 12 of 12 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 delete, send or pay without telling the client so: room_send
  • Tools that change data, on a server that answers without a sign-in: create_room, room_send, room_upload_link

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 →

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.
