MisarMail MCP Server vs Callrail MCP

list_accounts

List CallRail accounts accessible to this API key. Most users have one account per agency. The returned `id` is used as `account_id` in all other tools (auto-resolved if omitted).

list_companies

List companies (client businesses) under a CallRail account. Args: account_id: CallRail account ID. Auto-resolves if omitted. per_page: Page size (max 250). status: Filter by status. Defaults to None (returns all). Common values: 'active' (excludes disabled/soft-deleted), 'disabled'. page: 1-indexed. Agencies with more than `per_page` companies need this to reach the rest. Previously there was no way to fetch page 2 via this tool.

list_trackers

List tracking phone numbers (trackers). Each tracker maps a pool of phone numbers to a traffic source (Google Ads, Organic, Direct, etc.). Args: account_id: Auto-resolves if omitted. company_id: Filter to one company. per_page: Page size (max 250). page: 1-indexed. status: Filter by status. Defaults to None (returns all, including soft-deleted/disabled). Common values: 'active', 'disabled'.

get_tracker

Get full detail for a specific tracker. Args: tracker_id: 'TRK...' id. account_id: Auto-resolves if omitted.

create_tracker

⚠️ Create a new tracking phone number (tracker). **THIS COSTS MONEY.** CallRail charges per provisioned number. Typical pricing as of 2026: - Local numbers: ~$3/month each - Toll-free (8XX): ~$3-5/month each - Session pools: charged per number × pool_size (so pool_size=8 = 8x) - Plus per-minute usage (~$0.05/min on answered calls) Most plans bundle 5-10 numbers; provisioning beyond your bundle adds overage charges. Some plans prorate partial-month usage, so creating and immediately deleting can still produce a small charge depending on your contract. **You must pass `confirm_billing=True` to actually create.** This guards against accidental provisioning when an AI is exploring tools. Args: name: Display name for the tracker (e.g. "Google Ads Call Extension"). company_id: 'COM...' id of the company this tracker belongs to. destination_number: Where calls forward to, e.g. "+14129548337". confirm_billing: REQUIRED. Set True to acknowledge the per-number cost. Returns an error envelope if False (default). type: 'source' (single number tied to one traffic source) or 'session' (DNI pool that swaps numbers per visitor). Default 'source'. source_type: For type='source', which traffic source. One of VALID_SOURCE_TYPES: 'all', 'landing_url', 'landing_params', 'offline', 'web_referrer', 'direct', 'search', 'google_ad_extension' (what Google Ads call extensions use), 'mobile_ad_extension', 'google_my_business', plus the production-observed 'facebook_all' and 'bing_all'. Ignored for type='session'. area_code: 3-digit area code to provision the local number from (e.g. '412'). Ignored if `toll_free=True`. toll_free: If True, provision an 8XX toll-free number instead. pool_size: For type='session' only. How many numbers in the DNI pool. CallRail requires 4-50; each pool number is billed separately, so this multiplies your monthly cost. whisper_message: Spoken to the agent answering the call so they know which marketing source it came from. recording_enabled: Record the call audio. Default True. greeting_text: Optional automated greeting text-to-speech. sms_enabled: Allow this number to receive/send SMS. Default True. account_id: Auto-resolves if omitted. Returns the created tracker including its newly-provisioned tracking_numbers.

update_tracker

Update a tracker's mutable settings: name, destination, whisper, greeting, SMS. Args: tracker_id: 'TRK...' id. account_id: Auto-resolves if omitted. name: New display name. destination_number: Where calls forward (e.g. "+14129548337"). Updates the call_flow's destination too. whisper_message: New whisper text. greeting_text: New automated greeting. **If supplied, you must also supply destination_number**. CallRail's PUT /trackers replaces the entire call_flow object, so updating only greeting_text would silently zero out the destination, breaking the tracker. sms_enabled: Toggle SMS on/off. Field-level rules: - `name`, `destination_number`, `whisper_message`, `greeting_text` must be non-empty strings if provided. Pass `None` (the default) to leave a field unchanged. NOTE: Setting `status` via this PUT is silently ignored by CallRail. To disable a tracker, use `delete_tracker(tracker_id)` (soft-delete / disabled, keeps history). To permanently remove, contact CallRail support.

delete_tracker

Delete (disable) a tracker. Soft-removes it from active trackers; the tracker keeps its call history but stops receiving new calls. The underlying phone number is released. Args: tracker_id: 'TRK...' id. account_id: Auto-resolves if omitted. Returns: An object with `deleted: True`, `tracker_id`, and `response` (CallRail's body, which on success contains the disabled tracker record including `disabled_at` timestamp). Empty object if CallRail returned 204.

list_calls

List calls. Paginated. Filterable by company, date window, and answer status. Args: account_id: Auto-resolves if omitted. company_id: Filter to one company. Omit for all companies. days: Lookback in days (default 7). Ignored if `start_date` provided. start_date: 'YYYY-MM-DD'. end_date: 'YYYY-MM-DD' (defaults to today). answer_status: Server-side filter. One of 'answered', 'missed', 'voicemail'. This is CallRail's real filter parameter. answered: DEPRECATED alias kept for backwards compatibility. 'true' maps to answer_status='answered', 'false' to 'missed'. (CallRail has no `answered` query param; passing it used to be silently ignored, so results were unfiltered.) source: CallRail has NO server-side source filter, so this is applied CLIENT-SIDE to the current page only: the `calls` array is filtered by exact, case-insensitive match on each call's `source` field. `total_records`/`total_pages` in the response still describe the UNFILTERED query. See `source_filter` in the response for what was actually applied. For source breakdowns prefer `call_stats(group_by='source')`. per_page: Max 250. page: 1-indexed. fields: Comma-separated additional fields to include, e.g. 'company_name,source_name,keywords,landing_page_url,device_type, first_call,value,tags,note,gclid,fbclid,utm_source,utm_medium, utm_campaign,utm_content,utm_term,referrer_domain'.

get_call

Get full detail for a specific call. Args: call_id: CallRail call id (prefix 'CAL...'). account_id: Auto-resolves if omitted. fields: Comma-separated extra fields (see list_calls for common names).

call_summary

Summarize calls over a date window. Returns counts: total, answered/missed, first-time/repeat callers, total duration, and breakdowns by `source` and `source_name`. Useful for weekly/monthly rollups without pulling every call into context. Note: requires `days>=1` or an explicit `start_date`. Without a window this would paginate the entire account history (potentially 50+ pages of 250 calls each), which is rarely what callers want.

list_form_submissions

List form submissions captured by CallRail's Form Tracking. Paginated. Filterable by company and date window. Args: account_id: CallRail account ID. Auto-resolves if omitted. company_id: Filter to one company. Omit for all companies. days: Lookback in days (default 7). Ignored if `start_date` provided. start_date: 'YYYY-MM-DD'. end_date: 'YYYY-MM-DD' (defaults to today). per_page: Page size (max 250). page: 1-indexed. fields: Comma-separated additional fields to include, e.g. 'company_name,form_data,referrer,landing_page_url,source, utm_source,utm_medium,utm_campaign,utm_content,utm_term, gclid,fbclid,form_url,form_name'. Returns: JSON string with `page`, `per_page`, `total_pages`, `total_records`, and `form_submissions[]`. Each submission has id ('FOR...'), submitted_at, customer details (if captured), and a `form_data` dict keyed by form field name.

list_text_messages

List SMS/text message conversations sent to or received via CallRail trackers. Paginated. Filterable by company and date window. Receiving SMS works on standard accounts. Outbound SMS sending requires CallRail's A2P SMS API permission (returns 403 otherwise); see `create_text_message` notes if available on your plan. Args: account_id: CallRail account ID. Auto-resolves if omitted. company_id: Filter to one company. Omit for all companies. days: Lookback in days (default 7). Ignored if `start_date` provided. start_date: 'YYYY-MM-DD'. end_date: 'YYYY-MM-DD' (defaults to today). per_page: Page size (max 250). page: 1-indexed. Returns: JSON string with `page`, `per_page`, `total_pages`, `total_records`, and `conversations[]`. Each conversation has a list of inbound + outbound messages, customer phone number, the tracking number used, and timestamps.
