extraTools
is library-only in this first version; there is no CLI format for function handlers
How to use it
Project documentation lists extraTools for the MCP Openapi Server MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.

(default): Load all tools from the OpenAPI spec, applying any specified filters
Load only dynamic meta-tools (list-api-endpoints, get-api-endpoint-schema, invoke-api-endpoint). --exclude-tag still applies to dynamic endpoint discovery and invocation.
Load only tools explicitly listed in --tool options, ignoring include filters. --exclude-tag still applies as a deny filter.
