Add embed origin

add_embed_origin

Add one hostname to the project's embed allowlist (the hostnames permitted to load the public embed). Idempotent — re-adding an existing entry is a no-op. The origin is normalized to a bare lowercased hostname (scheme/port/path stripped). Morpha sends that website no request; any page on it may then load the project.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Input Schema

Name	Required	Description	Default
`origin`	Yes	Hostname or URL to allow, e.g. "example.com" or "https://example.com". Normalized to a bare lowercased hostname.
`projectId`	Yes	Opaque project id (a v4 UUID, from list_projects/create_project). Selects which existing project this call mutates.

Output Schema

Name	Required	Description
`ok`	Yes	Whether the call succeeded.
`data`	No	The payload, shaped by the tool.
`note`	No	What to do next when not ready.
`error`	No	Why it failed.
`status`	No	For cache-backed readers: whether the answer was ready.
`editorUrl`	No	Opens this project in the editor.

A4.4/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the annotations' readOnlyHint=false and destructiveHint=false, the description discloses idempotency ('re-adding an existing entry is a no-op') and the normalization rule (scheme/port/path stripped to a bare lowercased hostname). It also adds the security-relevant detail that Morpha sends the allowlisted website no request, so an agent understands what granting embed access entails.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Four sentences plus a documentation reference, with the primary purpose front-loaded. Each sentence earns its place: purpose, idempotency, normalization, and the no-request security note. The prose is slightly dense for a simple 2-param tool, which keeps it from a perfect score.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 2-param tool with 100% schema coverage, a true output schema, and annotations covering the mutation safety profile, the description covers everything an agent needs: purpose, idempotency, normalization, and access implications. The reference link provides an escape hatch for deeper questions, and return-value details are left to the output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with both origin and projectId fully documented in the input schema, so the description carries no additional parameter burden. The description's normalization note mirrors — rather than extends — the schema's own origin field description. Baseline 3 is appropriate when the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: 'Add one hostname to the project's embed allowlist.' It distinguishes itself from the many sibling add_* tools (add_audio_overlay, add_caption_track, etc.) by naming its exact target, and the 'one hostname' phrasing separates it from set_embed_origins and remove_embed_origin. An agent can select it correctly without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear context — this is an incremental, idempotent addition to the allowlist, explicitly scoped to a single hostname per call. It does not explicitly name alternatives like set_embed_origins for wholesale replacement or remove_embed_origin for removal, so exclusions are left implied rather than stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
