AdsAgent — Meta Ads MCP

campaigns_quick_create

Prepare new ads or append to an existing campaign/ad set using request.ad_account_id, a saved template, and one creative_source. Choose append_mode and target IDs explicitly. Use copy_ad_quick_copy for live-ad copies. Review the draft; launch_confirm executes after approval

A4.2/5.0

Behavior4/5

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

Annotations only indicate non-readOnly and non-destructive; the description adds the critical behavioral detail that this is a two-step process (prepare draft, then launch_confirm executes after approval). It does not disclose other side effects like rate limits or permission requirements, but given the annotations cover the safety profile, this is a strong addition.

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?

Two sentences, front-loaded with the core purpose and key decisions. It is concise but slightly dense; the mention of append_mode and target IDs could be clearer, yet it remains efficient without redundancy.

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

Completeness3/5

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

Given the tool's complexity (nested objects, many options) and the fact that an output schema exists (covering return values), the description still leaves gaps. It doesn't explain the append_mode enum values, the creative_source modes, or policy parameters. While the workflow is clear, an agent would need to rely on the schema for many details, making it adequate but not complete.

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 0%, so the description must compensate. It mentions key parameters (ad_account_id, template_name, creative_source, append_mode, target IDs) and notes that creative_source is singular, but many other parameters (execution, overrides, interest packs, naming, policies) are not explained. The description adds some meaning but is not comprehensive for the large parameter set.

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?

The description clearly states the tool prepares new ads or appends to an existing campaign/ad set using a saved template and creative source. It distinguishes itself from copy_ad_quick_copy for live-ad copies, giving a specific verb, resource, and scope. This makes the purpose unambiguous and differentiates it from siblings.

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

Usage Guidelines5/5

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

Explicitly names the alternative copy_ad_quick_copy for live-ad copies, and describes the workflow (prepare, review, then launch_confirm). It also instructs to choose append_mode and target IDs explicitly, guiding when to use append vs new. This provides clear usage context and exclusions.

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