BlvkWare MCP server

Which MCP servers are BlvkWare'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 namedev.blvkware/halluxverified in the MCP registry

The registry name sits under blvkware.dev. 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 391 ms.

Should an agent connect itNot proven either way yet
  • Whether its tools do the product's job has not been judged yet.
  • Checked on 1 of the 7 days it takes to judge reliability.

Once connected

  • For "check whether a package name exists before installing it", the likely first call is hallux_check.

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 · design an AI agent around one business job
  • can do · check whether a package name exists before installing it
  • not sure · benchmark how often a model invents package names

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 →

  • hallux_check_command

    Call this BEFORE running any command that installs a dependency: npm, yarn, pnpm, bun, pip, uv, poetry, pipx, cargo, go get, dotnet add package, nuget. Language models invent plausible package names that have never existed, and attackers…

  • hallux_check

    Does this identifier actually exist? Call before acting on any name you recalled rather than read: a package to install, a module to import, a DOI to cite. Returns one of: exists, deprecated, absent, phantom, squat, unknown. exists…

  • hallux_check_manifest

    Call this after writing or editing a dependency file, and before committing it. Supported: package.json, requirements.txt, pyproject.toml, Cargo.toml, go.mod. Checks every dependency in one pass, including dev and optional groups, which…

  • hallux_watch

    Register identifiers for notification when their verdict changes. The transition that matters is phantom to squat: a name models invent that somebody then registers. Use this for a dependency that came back `absent` or `phantom` and that…

How to connect

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

{
  "mcpServers": {
    "hallux": {
      "type": "http",
      "url": "https://api.blvkware.dev/hallux/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http blvkware https://api.blvkware.dev/hallux/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://api.blvkware.dev/hallux/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.
