ObraAberta MCP server
Which servers in the official MCP registry are ObraAberta's own, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

- Its tools do none of the product's use cases we checked: follow stages and updates of a purchased construction project; organise condominium documents and decisions in one workspace.
- Checked on 4 of the 7 days it takes to judge reliability.
Once connected
- Parameters are untyped or undescribed in 7 of 11 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
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 →

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.
