Verbex MCP server

Which MCP servers are Verbex'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.verbalexperiment/lab-toolsverified in the MCP registry

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

When we asked itchecked 2026-10-30
  • Stateanswerschecked 2026-10-30
  • Tools10
  • Server calls itselfverbex-lab-tools
  • Server version0.2.0
  • Protocol version2025-06-18

On 2026-10-30 the server answered initialize and tools/list without a sign-in. First answer in 198 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: plan plate layouts with sample, standard and control placement; calculate solution amounts from target concentration and final volume.
  • Checked on 4 of the 7 days it takes to judge reliability.

Once connected

  • For "plan plate layouts with sample, standard and control placement", the likely first call is plate_map.
  • For "calculate solution amounts from target concentration and final volume", the likely first call is solution_prep.
  • Parameters are untyped or undescribed in 7 of 10 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

  • can do · plan plate layouts with sample, standard and control placement
  • can do · calculate solution amounts from target concentration and final volume
  • not sure · fit standard curves and back-calculate sample concentrations

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 →

  • solution_prep

    Use when someone asks how much solid to weigh for a molar solution (how many grams for X mM in Y mL, making up a buffer or salt solution), or how much stock to dilute to a target concentration (C1V1). mode "solid": mass of solid to weigh…

  • serial_dilution

    Use for any serial dilution (standard curves, titrations, dose series). Plans transfer and diluent volume per tube and the resulting concentration at each step, from a stock concentration, a constant dilution factor, the number of tubes…

  • pcr_master_mix

How to connect

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

{
  "mcpServers": {
    "lab-tools": {
      "type": "http",
      "url": "https://www.verbalexperiment.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http verbalexperiment https://www.verbalexperiment.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://www.verbalexperiment.com/mcp as a custom connector in the settings.

OpenAPI spec

10 paths, read 2026-10-30. Open the spec ↗

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.
