Close

Search for activities. Results are returned ordered by date descending. Examples: - To list activities on a lead, use the lead_ids filter. - To list conversations, filter for calls and meetings. - Filter for Email to get individual messages, or EmailThread to get one result per conversation. An unfiltered search returns both.

Perform an aggregation to answer questions like: - How many emails were sent this week? - Calls by user this week (Who made the most?) You MUST first fetch the list of available fields using the `get_fields` tool.

Requiredinclude_types

Apply a previously proposed voice agent update. This tool persists the server-stored proposal identified by proposal_id. It does not rerun the feedback processor, and it fails if the proposal has expired or the voice agent changed after the proposal was created.

Use this tool when users ask about: - How to use specific Close features - Close API documentation and integration - Workflow automation and best practices - Product capabilities and limitations - Setup and configuration guidance Example queries: - "How do I set up automated lead assignment?" - "What are Close's API rate limits?" - "How to create custom fields in Close?" - "Best practices for email templates in Close"

Requiredlead_idcontact_id

Add a comment to a commentable object (note, call, opportunity, task, custom object, etc.). If the object already has a comment thread, the new comment is appended to it.

Comments support @-mentions of users and groups. The body is HTML.

To create a reply in an existing thread, provide the ID of the email being replied to via in_reply_to_id.

List all contact custom fields defined for the organization. Includes both contact-specific fields and shared fields associated with contacts. Returns each field's ID, name, description, type, allowed choices (for choice fields), whether multiple values are accepted, and whether it is a shared field. Useful for deciding which custom field to read or write when working with contacts.

When more than one agent exists, pick the most appropriate one based on the name.

List or find workflows

Use this tool ONLY to get a list of fields for the aggregation tool.

Cross-agent rollup for the Voice Agents list page. Returns one row per **active** agent — agents with completed calls in `date_range` **or** queued upcoming calls. Cumulative funnel counts (`answered`, `engaged`, `objective_met`) plus `total_calls`. `upcoming_calls` is the agent's queued (not yet completed) calls and is **not** bound by `date_range` — open tasks are open regardless of when scheduled (so an agent with only upcoming calls still appears). Use this to compare agents; for one agent's outcomes, sentiment, or time saved use `get_voice_agent_performance_report`. For an inventory of all configured voice agents regardless of activity, use `find_agent_configs`. The Voice Agents list (Agents tab) shows all-time stats, so leave `date_range` at its default (`all_time`) unless the user asks for a specific window. (The Upcoming and Recent tabs are call lists, not this rollup — search Calls for those.) Rows are sorted server-side per the `sort` field (default `most_calls`); pass a different mode rather than re-sorting in your reply. Set `reverse=True` to invert (e.g. `sort=most_calls, reverse=True` for least active first) — necessary to surface the bottom of the ordering, since `rows` are capped before they reach you. `truncated` and `total_agent_count` flag in-scope active agents; `dormant_agent_count` reports in-scope agents with **neither** completed calls in the date range **nor** queued upcoming calls (not included in `rows`).

Performance metrics for one voice agent. Returns the numbers shown on the Performance tab of a Voice Agent detail page. Passing multiple `agent_config_ids` pools metrics into a single aggregate (not a per-agent breakdown — for that, use `get_voice_agent_overview_report`). For per-call drill-down, search Calls filtered by `agent_config_id`. When the user is on a Voice Agent page, pull `date_range` from `page_context.date_range` so the numbers match the UI. Percentages: `*_pct` is over `total_calls`; `engaged_over_answered_pct` and `objective_met_over_answered_pct` are over `answered` (tier-to-tier conversion). For any other denominator, compute from `*_count`. `funnel_previous_period_deltas` is null when the date range has no defined previous period (e.g. `all_time`).

Requiredagent_config_ids

Return detailed configuration for one or more voice agents. Includes each agent's objective, user instructions, and which skills are enabled. Use this as the follow-up to `find_voice_agents` once one or more agent IDs have been selected.

Requiredagent_config_ids

Perform a simple lead search and return the initial set of results. Use this to retrieve all leads, most recent leads, search leads by keyword, or filter by lead status and smart view. For more complex searches use the `search` tool instead. Leads will be returned by last updated first.

List the roles that can be assigned in the organization. Covers Close's built-in roles plus any custom roles the org defines. Use this to resolve a role name to its id, or to see which roles grant organization management access.

Return general information about the organization and the user.

Return active users (memberships) which are part of the current org.

Paginate a search to retrieve more results. Provide exactly one of: - `search_id`: a `share_*` id from a previous search or shared entry, or - `smart_view_id`: a `save_*` Smart View (saved search) id the user is viewing.

Propose a voice agent configuration update from natural-language feedback. This tool does not apply changes to the voice agent. It returns a short behavioral summary and proposal ID when the requested edit is clear. If the feedback is ambiguous, it returns clarification questions instead of making a proposal. Use apply_voice_agent_update with the proposal ID only after the user approves the proposal.

Requiredagent_config_idfeedback

Schedule a voice agent to call a lead's contact. Creates a call task assigned to the voice agent. The voice agent will place the call automatically at the scheduled time, or as soon as the queue picks it up when no time is given. Use `find_voice_agents` first to discover which voice agents are available in this organization.

Requiredlead_idagent_config_id

Perform a natural language search for leads or contacts. If a more specific search tool (like lead_search or activity_search) satisfies the request, use that tool instead. You can reference related objects like activities (such as calls, emails, meetings, notes, custom activities, etc.), opportunities, tasks as long as they are part of a lead query. Example queries: - leads not contacted in the past week - leads assigned to me with uncompleted tasks - leads with an active opportunity over $500 - contacts with CTO title Each returned result will contain a title label, preview text, object ID, and URL. The initial set of results, total count of all results, and a URL to open the results in Close is returned. To retrieve more results, use the returned cursor and call the paginate_search tool using the cursor and search ID returned in this response.
