Successful Response

• success (boolean, required) — Indicates if the operation was successful.
• tools (list of Tool, required) — A list of tools available on the MCP server.
• tool_approval_statuses (list of MCPToolApprovalStatus, optional) — Derived approval states for currently discovered tools. Populated only for persisted MCP servers using per-tool approval; otherwise empty.
• error_message (string, optional, nullable) — Error message if the operation was not successful.

Validation Error

Definition for a tool the client can call.

• name (string, required)
• inputSchema (map from string to any, required)

• outputSchema (map from string to any, optional, nullable)
• icons (list of Icon, optional, nullable)
• annotations (ToolAnnotations, optional, nullable) — Additional properties describing a Tool to clients. NOTE: all properties in ToolAnnotations are hints.

• _meta (map from string to any, optional, nullable)

Derived approval state for a currently discovered MCP tool.

• tool_id (string, required) — Canonical MCP tool identifier in the form mcp:<server_id>:<tool_name>
• state (enum, required) — Whether a stored approval exists and still matches the live tool definition
  • Allowed values: up_to_date, needs_review, not_approved
• approval_policy (enum, optional, nullable, default: requires_approval) — Stored execution policy. Set when the tool has an approval.
  • Allowed values: auto_approved, requires_approval

• theme (enum, optional, nullable)
  • Allowed values: light, dark

Additional properties describing a Tool to clients. NOTE: all properties in ToolAnnotations are hints.

• title (string, optional, nullable)
• readOnlyHint (boolean, optional, nullable)
• destructiveHint (boolean, optional, nullable)
• idempotentHint (boolean, optional, nullable)
• openWorldHint (boolean, optional, nullable)
