McpServer.JS (HTTP MCP Server v0.8.0)

View Source

Provides inline JavaScript helpers for MCP Apps.

Use mcp_app_script/1 to embed the McpApp client class directly into an HTML template (e.g., EEx) so the iframe app has no external script dependencies. Server info from the MCP connection is baked into the script as default appInfo and protocolVersion.

Example

# In a .html.eex template:
<script><%= McpServer.JS.mcp_app_script(conn) %></script>

Functions

mcp_app_script(conn)

@spec mcp_app_script(McpServer.Conn.t()) :: String.t()
