Search for APIs by tag or keyword
AI agents call search_apis to retrieve information from Swagger Mcp Tool without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches and retrieves information from Swagger/OpenAPI documentation. Search operations are inherently non-destructive reads that do not create, modify, delete, or execute code. The worst misuse would be information disclosure of API documentation, which carries minimal blast radius.
From the tool's definition Tool name 'search_apis' and description 'Search for APIs by tag or keyword' indicate data retrieval without modification.
Attacks that exploit this kind of access
Search for APIs by tag or keyword. It is categorised as a Read tool in the Swagger Mcp Tool MCP Server, which means it retrieves data without modifying state.
Register the Swagger Mcp Tool MCP server in PolicyLayer and add a rule for search_apis: 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 Swagger Mcp Tool. Nothing to install.
search_apis 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 search_apis 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 search_apis. 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.
search_apis is provided by the Swagger Mcp Tool MCP server (sdlbp/swagger-mcp-tool). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
