Overview

This MCP server allows Claude/Cursor to search and explore OpenAPI specifications from oapis.org, providing summaries and details about API operations.

This MCP server is relatively safe for exploring and understanding APIs. However, users should be cautious about the information presented and verify it against other sources, especially when dealing with sensitive APIs. The risk is moderate as it primarily reads and summarizes API documentation, but the potential for misuse of the information exists.

Performance depends on the size and complexity of the OpenAPI specifications being processed. Network latency to oapis.org can also impact performance.

Cost is primarily related to the resources used to run the MCP server. There are no direct API call costs, but excessive usage could potentially lead to rate limiting by oapis.org.

Safety Score

moderate risk

Positive

+Primarily focuses on retrieving and summarizing OpenAPI specifications.
+No direct execution of API calls or modification of external systems.
+Relies on well-defined OpenAPI specifications, reducing ambiguity.
+Limited write capabilities, focused on retrieving and summarizing API documentation.

Risks

-Potential for information disclosure if OpenAPI specifications contain sensitive data.
-Dependence on the accuracy and security of oapis.org.
-Indirect risk if the retrieved OpenAPI specifications are used to exploit vulnerabilities in other systems.
-The summaries could be misleading if the OpenAPI specification is poorly written.
