robos:MCPServer

Validation shape for robos:MCPServer nodes in the core-platform package group.

Details


Class	`robos:MCPServer`
Also matches	`robos:ToolProvider`
Shape id	`urn:robos:shape:MCPServerShape`
Package	Core Platform (robos.platform) (`core-platform`)
Classification	Agents & MCP
Schema.org type	`schema:SoftwareApplication`
Domain standard	MCP specification

Properties

Count is the minimum and maximum number of values (* means no maximum). The validator enforces both. The type column is documentation only; the validator does not check types.

Property	Count	Type	Rule or description
`dcterms:title`	`1..*`	`xsd:string`	MCP Server must have a title or display name.
`robos:transport`	`1..*`	-	MCP Server must declare transport (stdio, Streamable HTTP, or legacy SSE).
`robos:toolsProvided`	`0..*`	-	Recorded tools are optional; resources-only and prompts-only MCP servers are valid.
`robos:endpoint`	`0..*`	-	Recorded server endpoint; optional for stdio and source declarations.
`robos:resourcesProvided`	`0..*`	-	Recorded resource node references; not live discovery.
`robos:promptsProvided`	`0..*`	-	Recorded prompt node references; not live discovery.

Example node

This node comes from .robos/kgraphs/core-platform/package.jsonld in the RobOS repository. That graph holds sample data for a fictional company, so treat the values as illustrations.

Validate the example

Save the example as node.json in the repository root, then run:

node -e "const { SHACLValidator } = require('./packages/robos-graph/lib/shacl-validator'); console.log(new SHACLValidator().validate([require('./node.json')]).conforms)"

The command prints true when the node meets every rule for its types.
