Serve dragonfarm's tools to MCP clients — dragon_mcp

Starts an MCP server (through the mcptools package) offering the tools from dragon_ellmer_tools(), so Claude Desktop, Claude Code, or another MCP client can search and ask your document sets and check your runs. Point the client at a command such as Rscript -e "dragonfarm::dragon_mcp_server()".

Usage

dragon_mcp_server(
  agent = NULL,
  tools = NULL,
  runs_dir = dragon_runs_dir(),
  ...
)

Arguments

agent: Name the caller as an agent in the policy (for example "answer"), so its calls are checked against what that agent may do. NULL (the default) means a person acting directly.
tools: Which tools to include, by name. NULL includes all.
runs_dir: Where document sets and runs live.
...: Passed to mcptools::mcp_server().

Value

Does not return while the server runs.

Details

The Python environment is located from a separate R process, because the helpers that locate it would otherwise read the client's messages.

Examples

if (FALSE) { # \dontrun{
# In the MCP client's configuration:
#   command: Rscript
#   args: ["-e", "dragonfarm::dragon_mcp_server()"]
dragon_mcp_server()
} # }
