How to connect Simplefunctions
Simplefunctions is a remote MCP server: there is nothing to install. Its endpoint is https://simplefunctions.dev/api/mcp/mcp, served over Streamable HTTP. In an assistant that accepts remote MCP servers (often under a setting named connectors, integrations or tools), add a new server and give it this URL; in a client configured by file, add it as a remote (HTTP) server with the same URL.
No headers are declared in the registry entry. If the server needs you to sign in, a client that supports MCP authorization opens the service's own sign-in page when it first connects.
It can also run locally from a Node.js package published to the npm registry: @spfunctions/cli version 1.7.22. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y @spfunctions/cli@1.7.22.
In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):
{
"mcpServers": {
"simplefunctions": {
"command": "npx",
"args": [
"-y",
"@spfunctions/cli@1.7.22"
]
}
}
