Apollo MCP
for AI agents

• add_contacts_to_sequence write

  Add Contacts to Sequence

  Adds contacts to a specified Apollo email sequence and returns the contact details. `sequence_id`, `emailer_campaign_id`, and `send_email_from_email_account_id` must be retrieved from Apollo listing/search endpoints before calling this tool — these IDs cannot be inferred from names.

• bulk_organization_enrichment read

  Bulk organization enrichment

  Enriches data for up to 10 organizations simultaneously by providing a list of their base company domains (e.g., 'apollo.io', not 'www.apollo.io'). Each call consumes Apollo credits per domain enriched; monitor quota to avoid exhaustion errors.

• bulk_people_enrichment read

  Bulk people enrichment

  Use to enrich multiple person profiles simultaneously with comprehensive data from Apollo's database. Each call consumes Apollo credits; avoid re-enriching the same contacts. Responses may include null or missing fields (e.g., email, phone, organization); treat unmatched records as valid 'no match' outcomes, not errors. Heavy use may trigger HTTP 429; respect Retry-After headers.

• bulk_update_account_stage write

  Bulk update account stage

  Bulk updates the stage for specified existing Apollo.io accounts, moving them to a valid new account stage.

• create_account write

  Create an Apollo account

  Creates a new account in Apollo.io; a new record is created even if a similar account exists, and provided `owner_id` or `account_stage_id` must be valid existing IDs. The response includes the new account's ID, which can be used directly in subsequent calls.

• create_bulk_accounts write

  Bulk create Apollo accounts

  Creates multiple accounts in Apollo.io with a single API call (maximum 100 accounts per request). Use when creating multiple company records at once.

• create_bulk_contacts write

  Bulk create Apollo contacts

  Tool to bulk create multiple contacts in Apollo with a single API call. Use when you need to create multiple contacts efficiently. Supports up to 100 contacts per request with optional deduplication.

• create_call_record write

  Create call record in Apollo

  Tool to log call records in Apollo from external systems. Use when recording calls made through outside systems like Orum or Nooks; requires a master API key and cannot dial prospects directly.

• create_contact write

  Create Apollo contact

  Creates a new contact in Apollo.io; use `account_id` to link to an organization and `contact_stage_id` for sales stage. Apollo does not auto-deduplicate — duplicate records sharing the same email are silently created; always search via APOLLO_SEARCH_CONTACTS before calling this tool. Requires explicit user confirmation before execution.

• create_custom_field write

  Create custom field

  Creates a new custom field in Apollo.io for contacts, accounts, or opportunities. Use when you need to define additional data fields beyond Apollo's standard attributes.

• create_deal write

  Create Apollo deal

  Creates a new sales opportunity (deal) in Apollo.io; all provided IDs (`owner_id`, `account_id`, `opportunity_stage_id`) must be valid existing Apollo identifiers. This action has persistent side effects — obtain explicit user confirmation before invoking.

• create_task write

  Create Apollo Task

  Tool to create a single task in Apollo.io. Use when you need to add a new task to your team's Apollo account for a specific contact. The task will be assigned to a user and includes details like type, status, priority, due date, and optional notes.

• get_account read

  Get Account by ID

  Tool to retrieve detailed information about a specific account by its Apollo ID. Use when you need to fetch complete account data including company details, contact information, and CRM integration fields.

• get_auth_status read

  Check Apollo API key status

  Tool to check whether the provided Apollo API key is valid and accepted by Apollo (health/auth check). Use when any Apollo endpoint returns 401/403/422 to quickly diagnose invalid/expired keys versus permission scope issues. If this succeeds but other endpoints return 403, it strongly suggests permissioning or master-key scope issues rather than a totally invalid credential.

• get_contact read

  Get Apollo Contact

  Retrieves detailed information about a specific contact by its ID. Use this to view contact details including name, email, phone numbers, organization, and custom fields.

• get_deal read

  Get Apollo deal

  Retrieves information about a specific deal by its ID. Use this when you need to view details of a single deal.

• get_labels read

  Get Labels

  Retrieves all labels from Apollo.io, used for organizing contacts and accounts. Call this before APOLLO_CREATE_CONTACT or APOLLO_UPDATE_ACCOUNT to validate label values against the returned list; mismatched labels cause 400/422 errors.

• get_opportunity_stages read

  Get opportunity stages

  Retrieves all configured opportunity (deal) stages from the Apollo.io account.

• get_organization read

  Get Organization by ID

  Retrieves complete information about a specific organization by its Apollo ID. Use when you need detailed company data including funding, technologies, employee counts, and more.

• get_typed_custom_fields read

  Get typed custom fields

• list_users read

  List Apollo Users

  Retrieves a list of all users (teammates) associated with the Apollo account, supporting pagination via `page` and `per_page` parameters. Use this to obtain numeric user IDs required by operations like APOLLO_UPDATE_CONTACT_OWNERSHIP — names or email addresses are not accepted in place of these IDs.

• organization_enrichment read

  Enrich organization data

  Fetches comprehensive organization enrichment data from Apollo.io for a given company domain; results are most meaningful if the company exists in Apollo's database. Each call consumes Apollo credits and may be unavailable on free plans. Returns HTTP 429 under burst usage; use exponential backoff on retries.

• organization_search read

  Search organizations in Apollo

  Searches Apollo's database for organizations using various filters; consumes credits on every call (unavailable on free plans) — avoid re-running identical queries and surface quota errors rather than retrying. Retrieves a maximum of 50,000 records; uses `page` (1-500) and `per_page` (1-100) for pagination — check `total_pages` in the response to iterate. Overly strict filter combinations can return zero results; start broad and narrow iteratively. Empty results and `org_not_found` are valid outcomes, not errors.

• people_enrichment read

  Enrich person with Apollo

  Enriches and retrieves information for a person from Apollo.io. Requires one of: `id`, `email`, `hashed_email`, `linkedin_url`, or (`first_name` and `last_name` with `organization_name` or `domain`) for matching. `webhook_url` must be provided if `reveal_phone_number` is true. Name-only inputs without `organization_name` or `domain` frequently return no matches.

• people_search read

  Apollo people search

  Searches Apollo's contact database for people using various filters; results capped at 50,000 records and does not enrich contact data. Combining multiple strict filters (organization_ids, person_titles, person_seniorities) can return zero results — start broad and narrow iteratively. Result records may have null email, phone, or organization fields.
