Labreador MCP server

Which MCP servers are Labreador'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.labreador/labreadorverified in the MCP registry

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

On 2026-10-20 the server answered initialize and tools/list without a sign-in. First answer in 96 ms.

Should an agent connect itNot proven either way yet
  • Whether its tools do the product's job has not been judged yet.

Once connected

  • Parameters are untyped or undescribed in 2 of 3 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

  • not sure · fit 4PL or 5PL curves to ELISA standards
  • not sure · calculate IC50 and EC50 from dose-response data
  • not sure · compute ecotoxicology pollution and bioaccumulation indices

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 →

  • fit_standard_curve

    Fit a 4PL or 5PL logistic curve to ELISA standards and optionally interpolate sample concentrations from their signals (OD). The result echoes the inputs received, lists data-quality warnings and includes the required Labreador citation.

  • dietary_risk

    Compute Estimated Daily Intake, Target Hazard Quotient per element, Hazard Index and optional cancer risk for contaminants in food. The result echoes the inputs received, lists plausibility warnings and includes the required Labreador…

  • pollution_indices

    Compute contamination factor and geoaccumulation index per element and the Pollution Load Index for one sample. The result echoes the inputs received, lists plausibility warnings and includes the required Labreador citation.

How to connect

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

{
  "mcpServers": {
    "labreador": {
      "type": "http",
      "url": "https://labreador.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

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

Add to CursorAdd to VS Code

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