## Install

### How to install SDSentry: Safety Data Sheet Lookup, GHS Pictograms & HazCom in Claude Code

1. Add the server

```bash
claude mcp add --transport http sds-lookup https://sdsentry.0xpi.com/mcp-sds
```

2. Verify it's connected

```bash
claude mcp list
```

3. Sharing it with your team?

   Add `--scope project` to write it to .mcp.json in the repository root, which you can commit (with the secrets left as environment variables).

4. Use it in a session

   Ask Claude to use the tools this server exposes (e.g. find_safety_data_sheet, check_hazcom_readiness, find_sds_for_inventory). It discovers them automatically.

### How to install SDSentry: Safety Data Sheet Lookup, GHS Pictograms & HazCom in Claude Desktop

1. Open your MCP config

   macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Add this server

```json
{
  "mcpServers": {
    "sds-lookup": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://sdsentry.0xpi.com/mcp-sds"
      ]
    }
  }
}
```

3. Why the wrapper?

   This is a remote (HTTP) server and Claude Desktop only launches local processes, so mcp-remote proxies the connection. It will open a browser window if the server needs OAuth.

4. Restart Claude Desktop

   The tools appear under the 🔌 menu once the app reloads.

[mcp_servers.sds-lookup]
command = "npx"

```

2. Why the wrapper?

   Codex runs MCP servers as local processes, so mcp-remote bridges this HTTP endpoint to stdio.

3. Run Codex

   Codex loads MCP servers from config.toml on startup and exposes their tools to the agent.
