Demonstrates how annotations can be used to provide metadata about content
AI agents call annotatedMessage to retrieve information from MCP Elicitations Demo Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a demonstration/showcase tool in an MCP elicitations demo server designed to illustrate annotation and metadata features. It retrieves and presents annotated content without modifying, executing, or destroying data. The 'annotations' and 'metadata' terminology indicates read-only retrieval of structured information about content.
From the tool's definition Tool name 'annotatedMessage' and description 'Demonstrates how annotations can be used to provide metadata about content' indicate a demonstration tool that retrieves or displays annotated message data.
Attacks that exploit this kind of access
Demonstrates how annotations can be used to provide metadata about content. It is categorised as a Read tool in the MCP Elicitations Demo Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Elicitations Demo Server MCP server in PolicyLayer and add a rule for annotatedMessage: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP Elicitations Demo Server. Nothing to install.
annotatedMessage is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the annotatedMessage rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for annotatedMessage. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
annotatedMessage is provided by the MCP Elicitations Demo Server MCP server (soriat/soria-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
