Analyze any API from its documentation URL. Generates a full provider config.
AI agents call semantic_discover_url to retrieve information from Semantic API without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs passive analysis of existing API documentation (a Read operation) with no ability to modify, delete, execute code, or make financial transactions. It transforms documentation into structured metadata. The blast radius of misuse is minimal—at worst, an agent generates incorrect or misleading API configurations, but cannot damage systems or data.
From the tool's definition Tool description states it 'Analyze[s]' API documentation and 'Generates' a provider config—read-only activities that retrieve and process publicly available documentation to produce informational output.
Attacks that exploit this kind of access
Analyze any API from its documentation URL. Generates a full provider config. It is categorised as a Read tool in the Semantic API MCP Server, which means it retrieves data without modifying state.
Register the Semantic API MCP server in PolicyLayer and add a rule for semantic_discover_url: 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 Semantic API. Nothing to install.
semantic_discover_url 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 semantic_discover_url 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 semantic_discover_url. 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.
semantic_discover_url is provided by the Semantic API MCP server (peter-j-thompson/semanticapi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
