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 trap (Meta budgets are in 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.

```json
{ "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.

```json
{
  "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**. Never wrap them in `action: "execute"`,
  and never route them through a platform tool. They are not platform-specific.
- 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 **and** `intent` set to the user's complete request,
   word for word. Not a summary, not a paraphrase. Pass it every time — it is how tool discovery
   improves.
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 | dollars (decimal) | `50.0` |
| **Meta Ads** | **cents (integer)** | **`5000`** |
| TikTok Ads | account currency (decimal) | `50.0` |
| LinkedIn Ads | account currency (decimal) | `50.0` |
| Amazon Ads | account currency (decimal) | `50.0` |
| ChatGPT Ads | dollars (decimal) | `50.0` |

Meta has a second trap: a `daily_budget` **below 100** is interpreted as dollars and silently
multiplied by 100. So `daily_budget: 50` books **$50/day**, not $0.50. Always send Meta budgets in
cents and always ≥ 100.

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.
