Configures and registers MCP (Model Context Protocol) tools in the
|
|
TrustGraph system.
|
|
|
|
MCP tools are external services that follow the Model Context Protocol
|
|
specification. This script stores MCP tool configurations with:
|
|
- id: Unique identifier for the tool
|
|
- remote-name: Name used by the MCP server (defaults to id)
|
|
- url: MCP server endpoint URL
|
|
- auth-token: Optional bearer token for authentication
|
|
|
|
Configurations are stored in the 'mcp' configuration group and can be
|
|
referenced by agent tools using the 'mcp-tool' type.
