-Convert OpenAPI spec to MCP server, OpenAPI operations as tools
+Convert OpenAPI spec to MCP server, OpenAPI operations as tools
+
+## CLI Options
+
+When running the MCP server, an OpenAPI spec is required. It can be either a file path or URL.
+
+The MCP server also provides options to filter operations to be converted as MCP tools.
+
+Currently supported filter conditions:
+
+|Condition|CLI option|Example|
+|---|---|---|
+|HTTP method| `--include-http-method` | `--include-http-method=GET` |
+|Path| `--include-path` | `--include-path=/holidays` |
+|Operation Id| `--include-operation-id` | `--include-operation-id=Root` |
+
+
+You can run the JAR file to see the CLI help.
+
+```
+Usage: openapi-mcp [-hV] [--include-http-method=<includeHttpMethods>[,
+                   <includeHttpMethods>...]]...
+                   [--include-operation-id=<includeOperationIds>[,
+                   <includeOperationIds>...]]... [--include-path=<includePaths>
+                   [,<includePaths>...]]... <openapiSpec>
+Run OpenAPI MCP server
+      <openapiSpec>   File path or URL of OpenAPI spec
+  -h, --help          Show this help message and exit.
+      --include-http-method=<includeHttpMethods>[,<includeHttpMethods>...]
+                      Include operations with HTTP methods (comma separated)
+      --include-operation-id=<includeOperationIds>[,<includeOperationIds>...]
+                      Include operations with id (comma separated)
+      --include-path=<includePaths>[,<includePaths>...]
+                      Include operations with paths (comma separated)
