# List projects

Canonical URL: https://sosoapi.ai/docs/mcp/list-projects

`sosoapi_list_projects`

List a Workspace's projects (an optional layer for provenance and account defaults) and which one is active.

## Profiles and transports

Profiles: 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.

  "destructiveHint": false,
  "idempotentHint": true,
  "openWorldHint": false

    "workspace_id": {
      "type": "string",

    },

      "minimum": 1,
      "maximum": 100,
      "description": "Page size, 1 to 100. Sending limit or cursor switches this route to cursor paging and adds next_cursor to the answer."
    },
    "cursor": {
      "type": "string",
      "minLength": 1,
      "maxLength": 512,
      "description": "Opaque cursor: the next_cursor of the previous page, unchanged. Omit it for the first page. The same filters must be sent with every page."
    },

## 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.
