## Response Size & Context Limits

`search_calls` can return a lot of data. Under the hood it:

- Auto-paginates up to **~5000 calls** (50 API pages) per query
- Applies client-side filters (participant, customer, tracker, duration, etc.) after pagination
- Returns a rich per-call format (metadata + summary + topics + participants) by default

**Guardrails built in:**

- If the formatted output would exceed **`MAX_MCP_OUTPUT_LENGTH`** (default `50000` chars, configurable via env var), the tool **automatically falls back to a compact table** with a warning. You still get every call ID and title — drill in with `get_call_summary` on specific ones.
- `include: ["outline"]` is **expensive** (~80KB per call). Avoid it in multi-call searches.
- Tracker data is filtered to only show trackers matching your `trackers` filter (or non-zero trackers if no filter) — no more walls of `(0x)` noise.

**If your query hits the output cap, narrow it:**

1. Tighten `fromDateTime` / `toDateTime`
2. Add `scope: "External"` or `scope: "Internal"`
3. Add `minDuration: 600` to skip short no-shows
4. Add `customerName` or `trackers` filter
5. Drop heavy `include` options like `outline`

## Available Tools

<a name="list_calls"></a>
<details>
<summary><code>list_calls</code> — List Gong calls with date filtering</summary>

List calls with optional date range and workspace filters. Returns minimal call metadata (ID, title, date, duration).

**Parameters:**

| Parameter | Required | Description |
|-----------|----------|-------------|
| `fromDateTime` | No | Start date in ISO 8601 format (e.g., `2024-01-01T00:00:00Z`) |
| `toDateTime` | No | End date in ISO 8601 format (e.g., `2024-01-31T23:59:59Z`) |

</details>

<a name="get_call"></a>
<details>
<summary><code>get_call</code> — Get metadata for a specific call</summary>

Get the URL, timing, direction, scope, system, and other metadata for one call. Faster than `get_call_summary` when you only need call metadata.

**Parameters:**

| Parameter | Required | Description |
|-----------|----------|-------------|
| `callId` | Yes | Gong call ID (numeric string) |

</details>

<a name="get_call_summary"></a>
<details>
<summary><code>get_call_summary</code> — AI-generated call summary</summary>

Get an AI-generated summary including brief overview, key points, topics, action items, and detailed outline. This is the recommended way to understand a call — use `get_call_transcript` only if you need exact quotes.

**Parameters:**

| Parameter | Required | Description |
|-----------|----------|-------------|
| `callId` | Yes | Gong call ID (numeric string) |

</details>

<a name="get_call_transcript"></a>
<details>
<summary><code>get_call_transcript</code> — Full speaker-attributed transcript</summary>

Get the raw transcript with speaker attribution. Transcripts are paginated (default 10KB) to prevent context overflow — use `maxLength` and `offset` to navigate.

**Parameters:**

| Parameter | Required | Description |
|-----------|----------|-------------|
| `callId` | Yes | Gong call ID (numeric string) |
| `maxLength` | No | Maximum characters to return (default: 10000, max: 100000) |
| `offset` | No | Character offset to start from for pagination (default: 0) |

</details>

<a name="search_calls"></a>
<details>
<summary><code>search_calls</code> — Advanced call search</summary>

Search calls with advanced filters including participant lookup, customer name search, and rich content selection. Automatically paginates through all results and returns participant info, brief summary, and topics by default.

**Parameters:**

*Date & workspace*

| Parameter | Description |
|-----------|-------------|
| `fromDateTime` | Start date in ISO 8601 format |
| `toDateTime` | End date in ISO 8601 format |
| `workspaceId` | Filter by workspace ID (use `list_workspaces` to find IDs) |
| `callIds` | Array of specific call IDs to retrieve |

*Host / participant*

| Parameter | Description |
|-----------|-------------|
| `primaryUserIds` | Host user IDs (server-side) |
| `primaryUserEmails` | Host emails (case-insensitive) |
| `excludePrimaryUserIds` | Exclude these host user IDs |
| `participantUserIds` | Any participant (host/attendee/invitee) user IDs |
| `excludeParticipantUserIds` | Exclude calls where any participant has these user IDs |
| `participantEmails` | Any participant emails (case-insensitive) |
| `excludeParticipantEmails` | Exclude calls where any participant has these emails |

*Content & customer*

| Parameter | Description |
|-----------|-------------|
| `customerName` | Fuzzy match against CRM account name, external email domains, and titles |
| `titleContains` | Substring match on call title (case-insensitive) |
| `trackers` | Calls where matching tracker(s) fired (count > 0). Workspace-specific — use `get_trackers` to discover |

*Metadata*

| Parameter | Description |
|-----------|-------------|
| `scope` | `External`, `Internal`, or `Unknown` |
| `direction` | `Inbound`, `Outbound`, `Conference`, or `Unknown` |
| `system` | Conferencing platform (e.g., `Zoom`) — case-insensitive substring |
| `language` | Language code (e.g., `eng`) — case-insensitive exact match |
| `minDuration` | Minimum duration in seconds |
| `maxDuration` | Maximum duration in seconds |

*Response shape*

| Parameter | Description |
|-----------|-------------|
| `include` | Additional data to return — see table below |

**`include` options:**

| Value | What it adds | Size |
|-------|-------------|------|
| `keyPoints` | AI-extracted key points as bullets | ~5KB/call |
| `trackers` | Keyword/smart tracker hits with counts | ~3KB/call |
| `highlights` | AI-curated highlight clips grouped by theme | ~3KB/call |
| `speakers` | Talk time per participant | ~1KB/call |
| `comments` | Public comments left on the call | varies |
| `context` | CRM account/opportunity linkage (HubSpot, Salesforce) | ~1KB/call |
| `outline` | Full section-by-section outline with items | **~80KB/call (large)** |
| `media` | Audio/video URLs (valid 8 hours) | ~3KB/call |

Defaults (always returned): participants, brief summary, and topics — ~3KB per call.

**Filter behavior notes:**

- Filters combine with **AND** logic. `primaryUserIds` + `participantUserIds` compose: primary narrows server-side, participant post-filters.
- `customerName` matches any of: CRM account Name field, external participant email domain, or call title (case-insensitive substring).
- `trackers` names are **workspace-specific** — call `get_trackers` first to see what's configured. Match is case-insensitive substring (so `"competitor"` matches both `"Competitors"` and `"Competitor Mentions"`).
- When `trackers` filter is set, the relevant tracker content is auto-included and the output shows only the trackers you asked about. Without a filter, only non-zero trackers are shown.
- An empty result returns `"No calls found"` rather than an error.

See [Response Size & Context Limits](#response-size--context-limits) for how large-result fallback works.

</details>

<a name="search_calls_by_account"></a>
<details>
<summary><code>search_calls_by_account</code> — Find calls by account/company (email domain)</summary>

Find calls involving a specific account or company by matching the email domains of external participants. The Gong API does not natively support filtering by account name (a [known gap](https://visioneers.gong.io/data-in-gong-71)) — this tool fetches calls in the date range and post-filters on `parties[].emailAddress`. Auto-paginates the underlying `/v2/calls/extensive` endpoint up to `maxCalls`.

**Use this when:**
- A prospect has multiple email domains (`acme.com`, `acme.io`, regional TLDs) and you need them all
- You need to join external enrichment data (e.g., "all prospects on Klaviyo" from BuiltWith / Clearbit / a vendor-stack graph) — resolve to a domain list upstream and pass it here
- Domain-based matching is more reliable than CRM Account names that drift across systems

**Parameters:**

| Parameter | Required | Description |
|-----------|----------|-------------|
| `domains` | **Yes** | Email domains, e.g. `["acme.com", "acme.io"]`. A call matches if any external participant has an email at one of these domains. |
| `fromDateTime` | No | Start date in ISO 8601 format |
| `toDateTime` | No | End date in ISO 8601 format |
| `workspaceId` | No | Filter by workspace ID |
| `primaryUserIds` | No | Pre-narrow by call host user IDs (faster, server-side) |
| `matchCrmAccount` | No | Also match where a CRM Account context object name contains a domain root (e.g. `"acme"` from `"acme.com"`). Requires CRM integration. Default `false`. |
| `maxCalls` | No | Max calls to fetch & filter (default: 500, max: 5000). Auto-paginates underlying API. |
| `cursor` | No | Pagination cursor (advanced) |

**Cost note:** This is fetch-then-filter. A 90-day window with no other narrowing typically pages through 1–5 API calls. Combine with `primaryUserIds` to bound cost on long ranges.

</details>

<a name="search_calls_by_opportunity"></a>
<details>
<summary><code>search_calls_by_opportunity</code> — Find calls linked to a CRM Opportunity</summary>

Find calls linked to specific CRM Opportunities by ID or name substring. Requires Gong-CRM integration (Salesforce / HubSpot) — calls without CRM linkage will not match.

**Use this when:**
- You want every call on a specific deal — `opportunityIds: ["006xxxxx"]` is the most precise option
- Opportunity names are descriptive (e.g. `"Acme Q4 Renewal"`) and you want fuzzy matching across renamed/duplicated opportunities

**Parameters:**

| Parameter | Required | Description |
|-----------|----------|-------------|
| `opportunityIds` | At least one of `opportunityIds` or `opportunityNames` is required | CRM Opportunity IDs (e.g., Salesforce 18-character IDs) |
| `opportunityNames` | At least one of `opportunityIds` or `opportunityNames` is required | Name substrings (case-insensitive) matched against the Name field of Opportunity context objects |
| `fromDateTime` | No | Start date in ISO 8601 format |
| `toDateTime` | No | End date in ISO 8601 format |
| `workspaceId` | No | Filter by workspace ID |
| `primaryUserIds` | No | Pre-narrow by call host user IDs |
| `maxCalls` | No | Max calls to fetch & filter (default: 500, max: 5000) |
| `cursor` | No | Pagination cursor (advanced) |

**Cost note:** Uses the same fetch-then-filter pattern as `search_calls_by_account`. CRM context lookup adds no extra API calls — it rides on the same `/v2/calls/extensive` request with `context: "Extended"`.

</details>

<a name="search_transcripts"></a>
<details>
<summary><code>search_transcripts</code> — Free-text keyword search across transcripts</summary>

Free-text keyword search across call transcript sentences within a bounded date range. Two-phase: (1) `/v2/calls/extensive` narrows the call set by date + optional `primaryUserIds` / `domains`, (2) `/v2/calls/transcript` fetches transcripts for the narrowed set and returns sentence-level matches with speaker attribution and timestamps.

**Prefer Gong Trackers for recurring terms.** For competitor names, ESP/tech terms (Klaviyo, Braze, Iterable, Postscript, Attentive, Sendgrid, Customer.io, etc.), and other terms you'll search for repeatedly — set them up as Gong Trackers in the UI (one-time, ~30 minutes for ~20 terms). Then use `get_trackers` + `search_calls` + `get_call_summary` instead. Trackers are server-side, the cost is dramatically lower, and they surface counts and timestamps natively. Use `search_transcripts` for ad-hoc one-offs.

**Cost guard:** Date ranges greater than 30 days require additional narrowing via `primaryUserIds` or `domains`. A 6-month unbounded scan would burn API quota and is rejected at the schema level.

**Parameters:**

| Parameter | Required | Description |
|-----------|----------|-------------|
| `keywords` | **Yes** | Keywords to search for. Each must be at least 2 characters. |
| `fromDateTime` | **Yes** | Start of date window (ISO 8601). |
| `toDateTime` | **Yes** | End of date window (ISO 8601). |
| `primaryUserIds` | Required if window > 30 days and `domains` not set | Narrow to calls hosted by these users before scanning |
| `domains` | Required if window > 30 days and `primaryUserIds` not set | Narrow to calls with external parties from these domains before scanning |
| `workspaceId` | No | Filter by workspace ID |
| `caseSensitive` | No | Default `false`. |
| `wholeWord` | No | Default `true` — `"ai"` will not match `"said"` or `"again"`. Set `false` for substring matching. |
| `maxCalls` | No | Max calls to scan (default: 500). |
| `maxMatchesPerCall` | No | Max sentence matches returned per call (default: 10) — prevents context overflow on calls with many hits. |

**Returns:** Sentence-level matches grouped by call, including speaker name and affiliation (when available), keyword matched, timestamp (mm:ss), and the sentence snippet.

</details>
