Overview

AI-generated overview

Remote MCP service for looking up Simpson Strong-Tie structural connectors and running basic load, holdown, hurricane-tie and seismic-category checks.

What you can do
Search the Simpson Strong-Tie catalog by product family, model or construction application, and read catalog summary statistics for free. Check whether a connector meets a required ASD load, size a holdown for uplift, and match a hurricane tie to uplift or lateral demand. Classify Seismic Design Category under ASCE 7-22 and map code sections to products. Advise on coating selection for a given environment and lumber type.
When to use it
Useful when an assistant is helping with wood-frame structural detailing and needs catalog lookups or quick preliminary connector sizing against Simpson Strong-Tie data and referenced codes. Most tools are billed per call, so it suits occasional, targeted queries rather than bulk catalog browsing.
Requirements
A remote streamable HTTP endpoint; no local package or runtime. Most tools require payment: the README describes the x402 protocol with USDC on Base L2 and an X-Payment-Hash header carrying the transaction hash. Internal Hive services use an X-API-Key header instead. Health, discovery, pricing and catalog statistics endpoints are described as free.
Before you install
Most tools cost money per call (roughly $0.01 to $0.03 each) and payment is in USDC on a blockchain, so an assistant could spend funds if allowed to call them freely. Calls send payment transaction hashes and, for internal access, an API key. Results are catalog and code lookups, not stamped engineering design; verify against official literature and a qualified engineer.

Installation

In SourceWeft

  1. Open Simpson Strong-Tie Agent in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.srotzin%2Fsimpson-strong-agent-service/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.
