Get the full content of a specific SHACL shape file with proper dereferencing
AI agents call get_shape_content to retrieve information from Earth616 Vocabulary Service without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns the contents of an existing SHACL shape file. It has no side effects, does not modify data, execute code, or delete anything. It is a straightforward read operation on documentation/ontology files, consistent with other sibling tools like discover_shapes, explore_vocabulary, and list_* tools on the same server.
From the tool's definition Tool is described as "Get the full content of a specific SHACL shape file" — it retrieves and returns file content without modification. The verb "Get" and absence of any language suggesting writes, deletions, or external operations indicate pure retrieval.
Attacks that exploit this kind of access
Get the full content of a specific SHACL shape file with proper dereferencing. It is categorised as a Read tool in the Earth616 Vocabulary Service MCP Server, which means it retrieves data without modifying state.
Register the Earth616 Vocabulary Service MCP server in PolicyLayer and add a rule for get_shape_content: 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 Earth616 Vocabulary Service. Nothing to install.
get_shape_content 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 get_shape_content 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 get_shape_content. 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.
get_shape_content is provided by the Earth616 Vocabulary Service MCP server (la3d/mcp_vocabulary_service). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
