Snapchat Ads MCP by InsightfulPipe

Snapchat Ads Execute Action

execute_action
Destructive

Execute Snapchat Ads action (Step 3 (FINAL) of workflow).

REQUIRED: Complete these steps first using query_contexts:

  1. request='accounts' - Get workspace_id, brand_id, ad_account_id AND available_actions

  2. request='actions_details' with actions=['xxxxxx', 'xxxxxx', 'xxxxxx'] - Get detailed body structure for specific action(s) using actions from available_actions

IMPORTANT: Always call step 2 to see the exact body structure before executing.

Rely on info from steps 1-2 to construct the action body. Follow the schema exactly.

TDQS

A3.9/5.0
Behavior3/5

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

Annotations already declare destructiveHint=true, openWorldHint=true and readOnlyHint=false, so the risk profile is covered structurally. The description adds the dependency chain and the requirement to derive the body from prior context, but never says what side effects occur, whether actions are reversible, or what permissions are needed.

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?

Numbered prerequisite steps are front-loaded and scannable, and the FINAL-step marker sets expectations immediately. The REQUIRED/IMPORTANT emphasis lines partly restate the numbered steps, costing a little tightness.

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

Completeness4/5

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

An output schema exists so return values need no explanation, and the description covers the one hard part — how to build an opaque body. Missing only failure behavior and any hint about which action categories are destructive, which matters for a tool flagged destructive.

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?

Only one parameter and 0% schema description coverage, but the schema is a free-form object with additionalProperties, so field-level documentation wasn't feasible anyway. The description does add real value by telling the agent to obtain the exact body shape from query_contexts request='actions_details' rather than guessing.

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

Purpose4/5

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

States a concrete verb and resource (execute a Snapchat Ads action) and frames it as the final step of a workflow, which separates it from query_data and query_contexts. What an 'action' actually is remains abstract, but the executor role is unmistakable.

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 prescribes the two prior query_contexts calls (request='accounts' then request='actions_details') and names the sibling tool to use for each. It also gives a hard 'always call step 2 first' instruction, leaving nothing to inference.

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