Steel Brain MCP

An MCP server providing steel domain knowledge to AI agents, exposing tools for grade lookup, substitution checks, and mill-cert guidance via remote HTTP or local stdio.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Vendor documentation

What its tools do

3 tools, grouped by the hints the server advertises. Hints are self-declared, not verified behavior.

Not annotated (3)

3 of 3 have a description · 0 of 3 declare behavior hints · 0 of 3 with parameters document them all

Checks and signals

Each line is separate evidence, not a trust score.

  • Passed Endpoint answered the live check ·
  • Availability 1 of 1 checks passed in 30 days

What you can do with it

  • Lookup properties, chemistry, and applications for a steel grade
  • Check if one steel grade can substitute another for a specific application
  • Determine which mill certificate applies for a grade and use case

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Steel domain knowledge from a verified trade knowledge base: grade properties, substitution verdicts, mill cert guidance. Never guesses - unknown grades return an honest not-in-KB response.

Tools

3 advertised

grade_lookup
Advertised by the server during the last successful anonymous check.

Look up a steel grade: properties, chemistry, forms, applications, weldability. Aliases accepted (e.g. 4140 = 42CrMo4 = SCM440).

grade_lookup input schema
{
  "type": "object",
  "title": "grade_lookupArguments",
  "required": [
    "grade"
  ],
  "properties": {
    "grade": {
      "type": "string",
      "title": "Grade"
    }
  }
}
substitution_check
Advertised by the server during the last successful anonymous check.

Check if one steel grade can substitute another for a given application (machined / welded-structural / pressure). Returns verdict + reasoning from verified trade rules.

  "type": "object",

    }
  }
}
cert_guide
Advertised by the server during the last successful anonymous check.

Which mill cert type applies for a grade + use case (e.g. EH36 shipbuilding), and what fields to check on the cert.

cert_guide input schema

  "type": "object",

90-day uptime

A lightweight connection check about every six hours, sampled on hosts with many listings. It shows the server answered, not that its tools work.

Too few checks for a percentage yet (2 of 2 answered).

  1. 2026-11-06: 1 of 1 checks answered
  2. 2026-11-07: 1 of 1 checks answered

30-day availability

Aggregated from read-only remote checks; this is not a tool-execution or security guarantee.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http steel-brain-mcp-steelbrain https://api.steelbrain.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add steel-brain-mcp-steelbrain --url https://api.steelbrain.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable steel-brain-mcp-steelbrain in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "steel-brain-mcp-steelbrain": {
      "url": "https://api.steelbrain.dev/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "steel-brain-mcp-steelbrain": {
      "type": "streamableHttp",
      "url": "https://api.steelbrain.dev/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start steel-brain-mcp-steelbrain and inspect its tools.
VS Code configuration
{
  "servers": {
    "steel-brain-mcp-steelbrain": {
      "type": "http",
      "url": "https://api.steelbrain.dev/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http steel-brain-mcp-steelbrain https://api.steelbrain.dev/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://api.steelbrain.dev/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "steel-brain-mcp-steelbrain": {
      "serverUrl": "https://api.steelbrain.dev/mcp"
    }
  }
