viaSocket MCP

Lets AI assistants use your apps through viaSocket: send an email, post to Slack, add a sheet row, read a CRM, on your own Gmail, Slack, Google Sheets, HubSpot or any of 2,300+ apps; automate across them; build and manage your plugins (apps) in the Developer Hub; and connect your product to other apps with the viaSocket SDK.

This is a remote MCP server (Streamable HTTP) at https://connect.viasocket.com/mcp. Nothing to install: your AI tool connects to it, and you sign in to viaSocket once through OAuth (the same account as viasocket.com). The docs tools work without signing in.

Tools

Using your apps (the connector): the guide for AI assistants is https://viasocket.com/docs/skill.md.

Connect from Cline

Install it from the Cline MCP Marketplace, or open MCP Servers → Configure MCP Servers and add this to cline_mcp_settings.json:

{
  "mcpServers": {
    "viasocket": {
      "type": "streamableHttp",
      "url": "https://connect.viasocket.com/mcp",
      "disabled": false,
      "autoApprove": []
    }
  }
}

Then use the sign-in button next to viasocket in the MCP Servers list and sign in to viaSocket in the browser. Agent-driven install steps are in llms-install.md.

Connect from Claude Code

claude mcp add --transport http viasocket https://connect.viasocket.com/mcp

then run /mcp and sign in.

MCP Registry

server.json is the listing for the official MCP Registry, as com.viasocket.mcp/mcp. The com.viasocket.mcp name is proven by owning the viasocket.com domain (a viasocket.com DNS login covers its subdomains too).

One-time setup: create a signing key and publish its public half on viasocket.com (Git Bash or any shell with OpenSSL):

openssl genpkey -algorithm Ed25519 -out mcp-registry-key.pem
echo "v=MCPv1; k=ed25519; p=$(openssl pkey -in mcp-registry-key.pem -pubout -outform DER | tail -c 32 | base64)"

Add the printed line as a TXT record on viasocket.com. Keep mcp-registry-key.pem private and out of this repo.

Publish (bump version first for any later change):

mcp-publisher login dns --domain viasocket.com --private-key "$(openssl pkey -in mcp-registry-key.pem -noout -text | grep -A3 'priv:' | tail -n +2 | tr -d ' :\n')"
mcp-publisher publish
