Overview, auth, credits, and MCP connection
Quick start, authentication, pagination, limits, credits, data scale, and connector metadata.
Context guidance: Use for onboarding an agent to Super Carl without loading endpoint or filter schemas.
Quick start
- Create an API key under MCP & API. API keys are available on any plan; usage still consumes the owner credit pool.
- Call /api/v1/credits to inspect the shared account credit pool, current-key usage, and the live search rate card before you scale up.
- Poll /api/v1/credits/status (or read X-Carl-Credits-* response headers on any authenticated call) to stay under your 30-day rolling credit ceiling. Exhaustion returns HTTP 402 with a credits_exhausted body — see credit_enforcement in the docs schema.
- Lookup a person by LinkedIn username or full LinkedIn profile URL using /api/v1/search/people (linkedin_username or linkedin_profile_url).
- Use the returned user_id to fetch cached profile chunks from /api/v1/profiles/:id/chunks.
- Call /api/v1/communications/capabilities before sending to learn which channels are actually available for the acting user and target.
- Create dry-run or live sends with /api/v1/communications; use GET /api/v1/communications/:id or /stream for status and artifacts.
- Use /api/v1/projects to list project workspaces, /targets to list/add/remove shortlist targets, /metrics to read outreach response rates, /templates to update saved templates, /messages/generate to draft personalized target messages, /target-users/:id/message or /targets/:id/message to save exact drafts, /send-readiness to check review state, and /activate to start approved project delivery.
- Run people searches with /api/v1/search/people; use description (alias query) which is auto-translated into structured filters unless you supply filters directly.
- Use /api/v1/search/people/enrich with a search_id to enrich one result or an entire page.
All API usage draws from the same account credit pool as in-app searches. Use /api/v1/credits for the live rate card and billing semantics. Communications are currently documented as not separately credit-billed.

"transport": "streamable_http",
"overview": "Super Carl ships a remote MCP server so agents (Claude, Claude Code, Cursor, Cowork, etc.) can read the authenticated account and professional profile, apply confirmed basic profile updates, run people / company / job / post search (with social-graph overlay), recover a paid people-search page without another search or credit, build evaluated recruiting shortlists, manage contact workflows, check channel readiness, draft/send communications, read Super Carl DMs, groups, and introduction requests, prepare Super Carl messages for approval in the app, discover employers for a required employer type, manage project state, export project results, and submit opt-in product feedback directly to Super Carl using the same backend as the web and mobile apps. For `people_search`, Free-form discovery: one bare result-producing people_search with the full NL query (or target_name for a named person), needed fields/evidence, and limit:N (max 25); omit limit with no count. Typed filters follow search_capabilities({tool_name:\"people_search\"}). Use mode:\"count\" only when a count is the answer. Inspect the returned `request.applied_request` and receipts before deciding whether a material continuation remains. If client capture truncates returned rows, use `replay_search_result` with `result_replay.source_search_id` and small slices; it preserves the recorded IDs/order, rehydrates current cached fields, does not rerun candidate search or call providers, and charges zero credits. Profile values may have changed since the original search. Revise a wrong mapping with a new people_search carrying the corrected query or filters; it starts a new filter state and supersedes prior rows. `collect_qualifying_count` is compatibility-only for an already-started specialized shortlist continuation. Larger hand-review workloads traverse ordinary advancing pages. `company_search` returns detailed company rows by default (limit up to 100); set `preview:true` only for a fast count/set review. Its pages are final (no offset): raise limit or adjust filters. `jobs_search` returns usable job rows by default; set `answer_projection:\"person.warm_paths\"` for the 'map a job to a path in' shape. `posts_search` returns matching post/activity rows with author identity by default; set `answer_projection:\"person.authors\"` only when distinct authors are the answer rows. `contacts_action` covers all-contact exports, contact sheet reconciliation, and reviewed work-email enrichment behind one dispatcher. `project_action` covers project shortlist, drafting, and delivery operations for MCP sessions that continue work after search or outreach. `bulk_export` is the canonical preview-confirm-start-status workflow for private CSV exports up to 5,000 rows and project Google Sheets up to 500 rows; pass an explicit user-requested count as `row_limit` on both preview and start.",

"note": "If Claude prompts for Connector Tool permissions, grant Always allow to read-only search/help tools when appropriate and keep mutating tools such as report_feedback, super_carl_action, send_communication, communication_action, project_action, bulk_export, contacts_action, and watch_signals on Needs approval unless you explicitly want Claude to run them without per-call confirmation. Super Carl advertises stable MCP tool metadata and read/write annotations, but persistence of Claude permission choices is controlled by Claude. If you are using Anthropic Cowork, your workspace admin must also allowlist api.supercarl.ai under Admin Settings > Capabilities > Code execution > Network egress > Additional allowed domains.

A named employer (name, domain, or LinkedIn company URL) goes directly in the clause where.identity (or the query), with no prior company_search. To reuse a company list the user reviewed, pass one of the short-lived `cohort_refs[].key` values that company_search returned, for example filters.companies:[{relation:\"current_employment\", operator:\"include\", cohort_ref:{key}}].

Only session-aware calls return session_binding; tools such as search_capabilities, discover_employers, get_product_help, account_read, and super_carl_action do not.

Do not retry it repeatedly, attempt report_feedback through the same blocked connector in that turn, or describe it as Super Carl admin, authentication, or authorization gating. If agent_session is blocked during an unattended, scheduled, headless, or background run, skip it and call the requested domain tool without agent_session_id so an implicit session can bind the work. Otherwise, ask the user to refresh or reconnect the Claude connector / refresh its tool list and choose Allow always for the affected read-only tool where Claude offers that permission. A later direct request to file feedback still counts as opt-in once the host permits the call.",

Typed or cached searches without AI keep their normal price; search preparation tokens remain included. Non-empty people_lookup_batch calls and exports use max(1, successfully completed rows / 100) credits. Every company identity lookup costs 0.01 credit per company, one at a time (company_search resolve_only) or per completed company_search_batch row, with no minimum. Successful Carl-hosted model activity and explicitly selected provider enrichment are converted to credits at provider cost using $0.099 per credit. Search preparation and designated platform work are included. Every authenticated response on enforced routes carries X-Carl-Credits-* headers; when the account owner hits the ceiling, billable endpoints return HTTP 402 with a credits_exhausted body and MCP tool calls return a handled structured result.",
