What this server can do

133 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

hires_add_candidate_tags(id, tags)

Add one or more tags to a candidate. Used for campaign tagging, qualification labels, and source attribution. Required: id, tags.

hires_add_hiring_team_member(id, user_id)

Add a company member to the job's hiring team. Use in workflow setup and ownership automation. Required: id, user_id.

hires_advance_application(id, include)

Advance an application to the next pipeline stage according to workflow order. No stage_id needed -- the system determines the next stage automatically. **Always pass `include=candidate,job`** when surfacing results in the widget — without it, the confirmation card can only show candidate/job IDs and cannot link to their backoffice pages. Required: id.

hires_batch_add_tags(ids, tags)

Add tags to multiple candidates in one request (max 100). Returns per-item results with partial success support. Required: ids, tags.

hires_batch_create_messages(messages)

Create up to 100 scheduled messages in one request. Each item specifies its own candidate_id and message payload. Items are processed independently -- one failure does not stop others. Per-candidate RBAC is enforced for each item. Required: messages.

hires_batch_job_boards(jobs)

Get board publication states for multiple jobs in one request. Optimized for batch monitoring and management UIs. Required: jobs.

hires_batch_move_applications(ids, stage_id)

Move multiple applications to a pipeline stage in one request. Returns per-item results with partial success support. Max 100 application IDs per request. Required: ids, stage_id.

hires_batch_publish_to_boards(jobs, boards)

Activate board publication for multiple jobs in one request. Use for bulk job distribution workflows. Required: jobs.

hires_batch_reject_applications(ids, rejection_reason_id)

Reject multiple applications in one request with an optional rejection reason. Returns per-item results with partial success support. Max 100 application IDs per request. Required: ids.

hires_batch_remove_from_boards(jobs, boards)

Deactivate board publication for multiple jobs in one request. Use for bulk depublishing workflows. Required: jobs.

hires_batch_remove_tags(ids, tags)

Remove tags from multiple candidates in one request (max 100). Returns per-item results with partial success support. Required: ids, tags.

hires_cancel_all_notification_messages(candidate_id)

Cancel all scheduled notification emails for a candidate. Already sent notifications are not affected. Returns success even if no scheduled notifications exist. Required: candidate_id.

hires_create_application(cv, job_id, include, stage_id, candidate_id)

Create an application by linking an existing candidate to a job. Use for sourcing workflows and manual application ingestion. The candidate must already exist. Required: candidate_id, job_id.

hires_create_candidate(city, email, phone, state, job_id, country, profile, stage_id, timezone, last_name, company_id, first_name, resume_text)

Create a new candidate profile. Optionally link to a job/stage and attach the candidate's resume as extracted text. Used for imports, inbound forms, and enrichment workflows. When the user provides an attached resume (PDF/DOCX/etc.), parse the file content yourself from the chat context — LLMs natively extract text from uploaded files — and pass the extracted text via resume_text. Do NOT attempt to inline binary file data: host function-call serializers truncate arguments above ~20KB.

hires_create_company(url, logo, name, website, company_owner_name, is_staffing_agency, company_owner_email, company_owner_phone)

Create a client company (partner tenant) — provisions its public career-site URL (slug) and public branding (logo, name). Typical entrypoint for multi-tenant onboarding. Required: name, company_owner_email, company_owner_name.

hires_create_email_template(body, name, subject, company_id)

Create a new email template with name, subject, and body. Subject and body support placeholders like {{first_name}}, {{job_title}}. To embed placeholders: 1) GET /template-placeholders to list them, 2) POST /template-placeholders/prepare to get the HTML tag, 3) insert the tag into the body. Required: name, subject, body.

hires_get_workflow_stages(id, company_id)

Get stages for a specific workflow by ID. Equivalent to hires_list_workflow_stages with workflow_id filter. Required: id.

Each entry has from_stage_id/name, to_stage_id/name, moved_at (Unix seconds), moved_by_type (system, user, automation), moved_by_user_id, and source (what caused the transition, e.g. 'apply:indeed', 'form_watcher', 'user'; null for historical records). Use this for funnel analysis, attribution reports, and time-in-stage reports instead of paginating through /candidates/{id}/activities when only stage data is needed. Required: id.

hires_list_applications(page, size, sort, job_id, status, include, stage_id, company_id, ai_score_max, ai_score_min, candidate_id, created_after, updated_after)

List applications across all accessible jobs. Supports filtering by candidate, job, stage, status, AI score range, and date ranges. Use for pipeline analytics, sync jobs, and ATS dashboards. Avoid include=candidate or include=cv.text on large pages (each embeds heavy nested data); if the response exceeds the budget the tool returns isError:true with error_code=response_too_large and retry hints. Each application embeds its current `stage` (IdName) directly in the response — this is sufficient for rendering kanban/pipeline views; you DO NOT need to call hires_get_job to fetch workflow_stages separately when rendering a pipeline.

hires_list_boards

List available publishing boards with metadata. Use for distribution setup and board selection.

hires_list_candidate_activities(id, page, size, view, since, until, event_type)

List timeline activities for a candidate (comments, stage moves, AI responses, etc.). Supports filtering by event type.

Required: id.

hires_list_candidate_files(id)

List all files attached to a candidate (resumes and other documents). Each entry has uuid, absolute download url (use Bearer auth), relative_time, file metadata (orig_file_name, file_ext, file_type/MIME, readable_size), and type (resume/other). Default response is compact; avoid include=text_content on candidates with many files — it adds parsed resume text per file which can exceed the response budget. Required: id.

hires_list_candidate_interviews(id, page, size)

List all interviews for a candidate across all applications. Useful for timeline views and scheduling conflict detection. Required: id.

hires_list_candidate_messages(id, page, size, view, is_scheduled)

List email and messaging history for a candidate. Use is_scheduled=1 to filter only pending scheduled messages. Recommended size <= 10: messages include full HTML body; if the response exceeds the budget the tool returns isError:true with error_code=response_too_large and retry hints. Required: id.

hires_list_candidate_tags(id)

List all tags assigned to a candidate. Useful for segmentation and audience-based automations. Required: id.

List candidates with optional filters. Supports filtering by job, stage, email, name, LinkedIn, and date ranges. Returns paginated results. Recommended size <= 10: candidate payloads include the full profile answers array and can be large; if the response exceeds the budget the tool returns isError:true with error_code=response_too_large and retry hints — reduce size, narrow filters, or fetch a single record via hires_get_candidate.

List users currently assigned to a job's hiring team. Useful for notification routing and collaboration tooling. Required: id.

hires_list_interviews(date, page, size, job_id, include, company_id, candidate_id, created_after, updated_after, application_id, interviewer_user_id)

List interviews with optional filters by job, application, candidate, interviewer, date, or timestamps for incremental sync. Returns paginated results. **Always pass `include=candidate`** when surfacing results in the agenda widget — without it, the widget can only show candidate IDs and cannot link cards to candidate profiles. Avoid include=job on large pages (embeds full job description per interview); if the response exceeds the budget the tool returns isError:true with error_code=response_too_large and retry hints.

hires_list_job_boards(id)

Get current board publication state for a specific job. Returns which job boards the job is published to. Useful for distribution dashboards and posting audits. Required: id.

Recommended size <= 10: messages include full HTML body; if the response exceeds the budget the tool returns isError:true with error_code=response_too_large and retry hints. Required: from_account_id.

hires_upload_attachment(file, category, object_id, company_id)

Upload a file and create an attachment. Supported categories: `voicemail` (wav/mp3, max 20 MB, no object_id — returned `uuid` is usable as `attachment_uuid` in nurture voicemail steps); `candidate` (candidate ID); `application` (application ID); `candidate_comment` (comment ID); `job_note` (job-note ID); `company_favicon`/`company_header`/`company_link_preview` (company ID).
