Security Report
5.2
Moderate5.2Moderate RiskThis is a well-engineered MCP server with proper OAuth 2.0 authentication, careful credential handling, and appropriate permission scoping. The code demonstrates solid security practices including JWT validation, token expiration checks, and explicit confirmation requirements for destructive operations. Minor code quality improvements around error handling and input validation are recommended, but pose no significant security risk. Supply chain analysis found 10 known vulnerabilities in dependencies (0 critical, 4 high severity). Package verification found 1 issue.

Permissions Required
This plugin requests these system permissions. Most are normal for its category.
What You'll Need
Set these up before or after installing:
Hostsmith app URL (OAuth endpoints).
Environment variable: HOSTSMITH_URL
Override the upstream API domain across both partitions; 'us.api.' and 'eu.api.' are prepended to this value.
Environment variable: HOSTSMITH_API_DOMAIN
Override the API base URL with a single fixed value, bypassing partition selection entirely.
Environment variable: HOSTSMITH_BASE_URL
How to Install & Connect
Available as Local & Remote

@hostsmith/mcp-server
Official Model Context Protocol server for the Hostsmith hosting platform.
Static hosting for agents - give it a file, get a live URL. Claude Code shipping an HTML report. Cursor previewing a generated demo. Claude Desktop publishing a one-pager. One MCP call → public HTTPS URL in seconds. No repo, no CI, no build step. Custom domains, private sites, EU or US data residency.
Why Hostsmith
- Artifact-first. No repo, no build config - drop a file (or have the agent generate one), get a URL.
- Built for agents. MCP-native, OAuth-scoped, structured tool descriptions agents can chain.
- EU or US data residency. Pick where the user's data lives, architecturally - not via a checkbox.
Tools
| Tool | Description |
|---|---|
list_sites | List all sites in your account for a given data partition |
get_site | Get details of a specific site |
create_site | Create a new site |
delete_site | Delete a site |
list_domains | List available domains (shared and custom) |
get_account | Get account info, subscription plan, and usage |
deploy_path | Deploy a local file or directory to a site |
deploy_files | Deploy inline file contents to a site |
Usage
Authentication is via OAuth 2.0. Static access tokens are not supported.
Claude Desktop
Open Settings → Connectors → Add custom connector and enter:
https://mcp.hostsmith.net/mcp
Claude Desktop runs the OAuth flow in your browser to authorize the connector against your Hostsmith account.
Stdio (Claude Code, Cursor, Cline, Windsurf, Zed)
Add this entry to your MCP client's config:
{
"mcpServers": {
"hostsmith": {
"command": "npx",
"args": ["-y", "@hostsmith/mcp-server"]
}
}
}
The first tool call triggers an OAuth flow in your browser to authorize the server against your Hostsmith account.
Remote URL (other clients)
Any MCP client that supports remote Streamable HTTP transport can point directly at the hosted server:
{
"mcpServers": {
"hostsmith": {
"url": "https://mcp.hostsmith.net/mcp"
}
}
}
The client handles the OAuth flow automatically - you'll be redirected to Hostsmith to authorize access.
Local HTTP (self-hosted)
Run the server in HTTP mode and have your MCP client perform OAuth against it:
npx @hostsmith/mcp-server http
{
"mcpServers": {
"hostsmith": {
"url": "http://localhost:3100/mcp"
}
}
}
Environment variables
| Variable | Default | Description |
|---|---|---|
HOSTSMITH_URL | https://hostsmith.net | Hostsmith app URL (OAuth endpoints). |
HOSTSMITH_API_DOMAIN | - | Override the upstream API domain across both partitions. The server prepends us.api. and eu.api. to the value you set. Example: HOSTSMITH_API_DOMAIN=staging.example.com routes calls to https://us.api.staging.example.com and https://eu.api.staging.example.com. Use this to point at a staging or proxied API host. |
HOSTSMITH_BASE_URL | - | Override the API base URL with a single fixed value, bypassing partition selection entirely. |
PORT | 3100 | HTTP server port. |
MCP_BASE_URL | http://localhost:$PORT | Public URL of the MCP server, used in OAuth metadata. |
Troubleshooting
- Tool calls return 401: the OAuth session expired. Reconnect from your MCP client to re-authorize.
- OAuth redirect loops: confirm
MCP_BASE_URLmatches the URL your MCP client uses to reach the server. - Wrong partition: tool calls accept an explicit
partitionarg; if you omit it, the partition is inferred from your access token. - Inspect the install:
npx @modelcontextprotocol/inspector npx -y @hostsmith/mcp-server httpto browse tools interactively.
