Detailed Description

Wraps a remote MCP server tool as a local Tool.

MCPTool implements the Tool interface by forwarding execute() calls through the owning transport (HTTP or stdio). Created automatically by MCPClient::get_tools().

Constructor & Destructor Documentation

MCPTool() [1/2]

neograph::mcp::MCPTool::MCPTool	(	const std::string &	server_url,
		const std::string &	name,
		const std::string &	description,
		const json &	input_schema
	)

HTTP-mode constructor.

Each execute() opens an ephemeral MCPClient against server_url.

MCPTool() [2/2]

neograph::mcp::MCPTool::MCPTool	(	std::shared_ptr< detail::StdioSession >	session,
		const std::string &	name,
		const std::string &	description,
		const json &	input_schema
	)

stdio-mode constructor.

The MCPTool keeps the session alive — the subprocess stays up as long as any tool instance holds a reference to it.

Member Function Documentation

execute()

std::string neograph::mcp::MCPTool::execute ( const json &  arguments )

overridevirtual

Execute the tool on the MCP server.

Parameters

arguments

JSON object containing the tool's input parameters.

Returns

Result string (text content joined by newlines) or JSON dump.

Implements neograph::Tool.

get_definition()

ChatTool neograph::mcp::MCPTool::get_definition ( ) const

overridevirtual

Get the tool definition metadata.

Returns a ChatTool containing the tool's name, description, and JSON Schema for its parameters. This is sent to the LLM so it can decide when to call the tool.

Returns

Tool definition including name, description, and parameter schema.

Implements neograph::Tool.

get_name()

std::string neograph::mcp::MCPTool::get_name ( ) const

inlineoverridevirtual

Get the tool name.

Returns

Tool name string (must match the name in get_definition()).

Implements neograph::Tool.
