Server-provided instructions

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

Structomat is an AI engineering agent for structural steel: structural (static) analysis and design, connection design, calculation reports and shop drawings, reviewed and signed by a licensed partner engineer for construction. Use about_structomat for facts, find_examples for evidence from published work, estimate_portal_frame_steel for a quick steel tonnage of a portal frame building, analyze_frame to run a 3D finite-element frame analysis and get the numbers (deflections, sway, reactions, member forces, periods) with a link that shows them in 3D, and draft_project_request to prepare an e-mail the user sends. Nothing is stored.

Advertised by the server during the last successful anonymous check.

Advertised read-only

Search Structomat's published work: steel projects, case studies, example situations, checked steel connections, measured benchmarks (e.g. scan-to-BIM from a point cloud), sample deliverables (e.g. a complete US AISC shop drawing submittal with a clouded revision, or an erectability check that finds the pieces of a clash-free model that cannot get into place during erection) and free tools. Returns titles, links and short summaries.

estimate_portal_frame_steel — Estimate the steel of a portal frame building

Advertised by the server during the last successful anonymous check.

Advertised read-only

Steel tonnage estimate for a single-span pitched portal frame building (span 15-30 m) before any design: total tonnes, kg per m2 of floor, a range, the weight by part (frames, gable posts, bracing, eave struts, purlins, side rails, plates and connections) and typical member sizes. Interpolated between complete finite-element designs and calibrated against published designs. Use for budgets, tenders and feasibility; a real design needs the actual loads and code.

analyze_frame — Analyze a 3D steel frame (finite elements, returns the numbers)

Advertised by the server during the last successful anonymous check.

Advertised read-only

Runs a 3D finite-element frame analysis and returns the numbers: equilibrium check, largest deflection along the members, largest joint displacement and sway in X and Y, every support reaction, the axial force, shears and moments of every member (the envelope with the governing combination when there are several), and natural periods with mass participation (modal analysis); linear or second order (P-Delta). The model is either a template (a pitched portal frame building, an open mono-pitch canopy, or a multi-storey frame, from a few dimensions, sections and loads) or a full model in JSON (nodes, members, sections, supports, loads, combinations). It is solved by the code of Structomat's free 3D frame analysis page, so the result also has a link that shows the same model and results in 3D (deflected shape, force diagrams, mode shapes). Use it to check a frame, compare sections or see how loads flow, and run it again with changed sections or loads. Elastic analysis only, not a code check: member buckling, connection design and code load combinations are not covered. Nothing is stored.

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 structomat-mcp https://structomat.com/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 structomat-mcp --url https://structomat.com/mcp/

Cursor

Merge this server into .cursor/mcp.json in your project, then enable structomat-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "structomat-mcp": {
      "url": "https://structomat.com/mcp/"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "structomat-mcp": {
      "type": "streamableHttp",
      "url": "https://structomat.com/mcp/",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start structomat-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "structomat-mcp": {
      "type": "http",
      "url": "https://structomat.com/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 structomat-mcp https://structomat.com/mcp/

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "structomat-mcp": {
      "url": "https://structomat.com/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": {
    "structomat-mcp": {
      "serverUrl": "https://structomat.com/mcp/"
    }
  }
}
