Annotates a Shiny input or output tag with data-shinymcp-* attributes
so it can be discovered by the MCP JS bridge. Auto-detects whether the
tag is an input or output by inspecting Shiny's class conventions.
Usage
bindMcp(tag, ...)
# S3 method for class 'shiny.tag'
bindMcp(tag, id = NULL, type = NULL, ...)
# S3 method for class 'shiny.tag.list'
bindMcp(tag, id = NULL, type = NULL, ...)
# Default S3 method
bindMcp(tag, ...)Arguments
- tag
A shiny.tag or shiny.tag.list produced by a Shiny input or output function.
- ...
Reserved for future use.
- id
Override the input/output ID. If
NULL(default), the ID is auto-detected from the tag structure.- type
Override the output type (
"text","html","plot", or"table"). Only used for outputs. IfNULL, auto-detected.
Value
The modified htmltools::tag with MCP attributes stamped.
Details
Use this as a pipe on standard Shiny UI elements:
selectInput("x", "X", c("a", "b")) |> bindMcp()
plotOutput("plot") |> bindMcp()bindMcp() is idempotent: calling it on an element that already has
data-shinymcp-input or data-shinymcp-output attributes is a no-op.
