# Typed MCP Results
URL: https://docs.autociso.io/release-notes/2026-10-mcp-typed-outputs/
Description: Eleven MCP tools now return structured results, and both SDKs give you typed values for them.

## Typed MCP results

**Plans:** same as each tool's plan (see the [Tool Catalog](https://docs.autociso.io/developers/mcp/tools/))
**Where:** MCP server and the TypeScript and Python SDKs

Eleven MCP tools now return their result as `structuredContent` in addition to the text block, and both SDKs turn it into typed values, so you stop hand-writing types for `uar_status` or `evidence_log`.

**Who benefits:** integrators and engineers who call AutoCISO from scripts, agents or the SDKs.

### What's new

- Successful calls of the eleven typed tools carry `structuredContent` with the same masked JSON as the text block. The server advertises `outputSchema` on `tools/list` after a seven-day soak, and never for `employee_resolve`.
- TypeScript: typed `ToolResult` per typed tool, and a new `ResultShapeError`. Casting `.data` directly to an unrelated type now needs `as unknown as`.
- Python: `TypedToolResult[XResult]` with a lazy `.result` that raises `ResultSchemaError`; the package ships `py.typed`.
- A typed tool that returns nothing now gives `INTERNAL_ERROR`; results over 256 KiB give `RESULT_TOO_LARGE`.

### How to use it

1. Update the SDK to the next release.
2. Read `res.data` (TypeScript) or `res.result` (Python) and let your editor complete the fields.
3. Check the **Result** column in the [Tool Catalog](https://docs.autociso.io/developers/mcp/tools/) to see which tools are typed. The other 54 are unchanged. See [TypeScript SDK](https://docs.autociso.io/developers/mcp/typescript-sdk/#typed-results) and [Python SDK](https://docs.autociso.io/developers/mcp/python-sdk/#typed-results).
