Source types
OpenAPI
Fetches an OpenAPI/Swagger specification and auto-generates tools from each endpoint.
Tool path generation:
namespace.resource.action (e.g., billing.invoices.list).
Action is derived from HTTP method: GET -> list/get, POST -> create, PUT -> update, PATCH -> patch, DELETE -> delete.
Destructiveness: Derived from HTTP method. GET, HEAD, OPTIONS are safe; all others are destructive.
GraphQL
Introspects a GraphQL schema and generates tools from queries and mutations.
Tool path generation:
namespace.field_name (camelCase converted to snake_case).
Destructiveness: Queries are safe, mutations are destructive.
MCP
Connects to an external MCP server and imports its tools.
Tool path generation:
namespace.tool_name (spaces and non-alphanumeric characters converted to underscores).
Destructiveness: Reads annotations.destructiveHint from MCP tool metadata.
Stdio transport is defined in the config schema but not yet implemented in the adapter.
Plugin
Wraps a hand-writtendefinePlugin() result as a source for registry consistency.
Authentication types
Theauth field supports four types:
Registering via API
SourceConfigSchema, calls resolveSource() to fetch and parse the spec, and registers all discovered tools in the catalog.
