Profiles and transports

Profiles: core, full · Transports: stdio, http

Choose core or full to control which tools your client sees; this does not change its permissions. Local file upload requires stdio and is unavailable over HTTP. Set SOSOAPI_OUTPUT_SCHEMAS=1 to include output schemas in discovery. Tools return structured results with or without that setting.

Permissions and side effects

Annotations help clients describe a tool. Each call still checks the user’s authentication, role, resource access and capability grants.

Input fields

Required means required inside its parent object and selected branch. A required child does not make an optional parent required. Rules and field names below are copied from the contract.

Structured output

This schema describes structuredContent in a successful tool result. The MCP response also includes content and may set isError when a call fails. For publishing, read the post’s final result rather than treating an accepted request or text response as confirmation. The linked API operation explains permissions and retry rules.

Required means required inside its parent object and selected branch. A required child does not make an optional parent required. Rules and field names below are copied from the contract.
