MCP Annotations

MCP Annotations are metadata hints that an MCP server attaches to each tool definition to tell the client (the AI agent or host application) about the tool’s behavioral characteristics. They’re part of the MCP spec and help clients make smarter decisions about tool usage without needing to understand the tool’s implementation.

Each tool includes behavior annotations:

Annotation	Meaning
`readOnlyHint`	`true` = read-only, no mutations.
`destructiveHint`	`true` = may create/modify/delete resources.
`idempotentHint`	`true` = repeated calls produce same result.
`openWorldHint`	`true` = interacts with external systems.

How they work with tools in practice

Each tool in the Stitch MCP server declares these as part of its tool registration. For example:

list_projects has readOnlyHint: true — it just fetches data, so an agent can call it without worrying about side effects.
create_project has readOnlyHint: false, destructiveHint: true, idempotentHint: false — it mutates state, so the client should confirm with the user first.
generate_screen_from_text has destructiveHint: true and idempotentHint: false — each call creates a new screen, so retrying on a timeout could produce duplicates.

Why they matter

These are hints, not enforced rules. They allow MCP clients to:

Auto-approve read-only tools without prompting the user
Show confirmation dialogs for destructive operations
Safely retry idempotent tools on network failures
Audit external interactions when openWorldHint is true

In the Stitch server’s case, all tools have openWorldHint: false because they interact only with the Stitch backend — not arbitrary third-party services.
