name: adspirer-mcp description: How to call the Adspirer MCP hub correctly — the router two-step (action "list_tools" then action "execute" with tool_name), the direct tools search_tools and get_tool_schema, per-platform account IDs, quota rules, and the budget unit (every platform takes the account's own currency as a decimal — never cents). Load this before making any Adspirer tool call.

Calling the Adspirer MCP hub

Adspirer exposes 20 top-level tools. Six of them are routers that stand in front of hundreds of platform tools. Calling a platform tool by its own name does not work — it is not in the tool list. Read this before your first tool call.

The tool surface

Call these directly, by name:

Tool	Use it for
start_here	New or unsure user. Free.
search_tools	"Which tool does X?" Semantic search over every tool.
get_tool_schema	Exact parameters for a tool, before you call it.
get_connections_status	Which ad accounts are connected, and their health. Free.
get_usage_status	Plan, quota, usage this period. Free.
switch_primary_account	Change which account is active.
get_campaign_performance	Google Ads performance.
get_meta_campaign_performance	Meta (Facebook/Instagram) performance.
audit_conversion_tracking	Conversion-tracking health across platforms.
echo_test	Connectivity check. Free.

These are routers. Never call their inner tools by name:

google_ads · meta_ads · linkedin_ads · tiktok_ads · amazon_ads · chatgpt_ads · monitoring_and_reporting · community_plugins · google_analytics · klaviyo

The router two-step

Every router takes the same three fields: action, tool_name, arguments.

Step 1 — discover. Always first. Never costs quota.

{ "action": "list_tools" }

Returns every tool on that platform with its full parameter schema.

Step 2 — execute. Use an exact tool_name from step 1.

{
  "action": "execute",
  "tool_name": "list_tiktok_campaigns",
  "arguments": { "advertiser_id": "7012345678901234567" }
}

Rules

• action: "execute" without a tool_name is invalid. It returns an error. Do not retry the same call — go back to list_tools and read the real tool name.
• Never pass a platform tool name as action. action is only ever "list_tools" or "execute".
• search_tools and get_tool_schema are top-level. Call them directly when they are in your tool list. If your client does not list get_tool_schema, call it through any platform router: google_ads with action: "execute", tool_name: "get_tool_schema", arguments: {"tool_names": [...]}. It returns the same schema. Never stop because it is missing.
• Never guess a tool name or a parameter. If you are unsure, call list_tools or get_tool_schema.

Finding the right tool

When you don't know which tool does the job:

1. search_tools with a natural-language description of the task.
2. get_tool_schema with the candidate names to get their exact parameters. Not in your tool list? Call it through a router (see Rules above).
3. Call the tool: directly if it's in the direct list above, otherwise through its router with action: "execute".

Budgets: the unit differs per platform

This is the single most common error. Read the row before you send a budget.

Platform	Unit	$50/day becomes
Google Ads	account currency (decimal)	50.0
Meta Ads	account currency (decimal)	50.0
TikTok Ads	account currency (decimal)	50.0
LinkedIn Ads	account currency (decimal)	50.0
Amazon Ads	account currency (decimal)	50.0
ChatGPT Ads	account currency (decimal)	50.0

Every platform takes the budget in the account's own currency as a plain decimal — never cents, never multiplied by anything. For a $20/day budget send 20, not 2000. For $50/day send 50. The tools convert to each platform's internal unit for you; if you send 2000 meaning $20 you will book $2,000/day — a 100× overspend.

Never convert the user's currency to USD. Send the number in the account's own currency.

Accounts

One connected account is selected automatically. With two or more active accounts you must name one — the call fails with a multi_account error that lists them.

The parameter name differs per platform:

Platform	Parameter
Google Ads	customer_id
Meta Ads	ad_account_id
TikTok Ads	advertiser_id
LinkedIn Ads	account_id
Amazon Ads	profile_id
ChatGPT Ads	account_id

Send IDs as strings, not numbers. Naming an account the user has not connected returns a 403 — it never quietly falls back to another account, so do not treat 403 as "try again without the id."

Use get_connections_status to see what is connected.

Quota

Every tool call against a platform costs one call from the user's monthly quota (Free 15 · Plus 150 · Pro 600 · Max 3,000).

Free — call these as much as you need: action: "list_tools" on any router, start_here, get_connections_status, get_usage_status, echo_test, and everything under community_plugins.

Because discovery is free, there is never a reason to guess a tool name to save quota.

When a user runs out: Plus/Pro/Max monthly plans keep working and bill per extra call; annual plans stop at the cap. Show the error message you receive — it carries the upgrade link. Do not work around a quota error or invent the data.

Tools that may not be there

google_analytics and klaviyo appear only when the user has connected that service. If you don't see the tool, the connection is missing — say so and point them at https://adspirer.ai/connections. Don't insist the tool exists.

When something fails

Read references/error-catalog.md for the known error codes and their fixes before retrying anything. Retrying an invalid call unchanged will fail the same way.
