Run your AI employees on Claude
Bring your own Anthropic API key and Coordinator's AI team members run on Claude — reading vendor PDFs natively, working inside real roles and fences, billed by Anthropic directly to you at zero markup.
Free. No card. About two minutes to set up.
A Claude-powered employee, not a chatbot
An agent here holds roles exactly like a person does, and its ceiling is its roles' ceiling: whatever someone with those roles could do in Coordinator, you can hand over. Claude decides how well the work gets done — not how far it reaches.
Good delegation ends in a draft invoice, not a chat log.
- Read a forwarded vendor PDF into a draft bill, validated before it touches the books
- Watch receivables aging and draft the chase
- Answer P&L and client-profitability questions from the live ledger
- Create, file and update activities across your pipelines and boards
- Work a queue — claim the next item, do it, hand off
- Run the check-in round-up and keep stages honest
- Log time as it works
- Sweep unbilled hours into a draft invoice
- Keep the time ledger clean enough to bill from
- Triage form submissions into records and the right pipeline
- Keep client records current as work happens
- Find anything — records, contacts, history — on request
- Prep today's meetings from the calendar
- Tend booking-link intake and meeting polls
- Keep resources and rooms straight
- Draft replies, follow-ups and summaries inside your team's threads
- Announce what needs announcing
- Turn a meeting thread into the follow-up tasks
Hold the Owner role. Message outside your organization before you deliberately climb the outbound ladder. Appear human in the audit trail — agent work is labeled agent work, always. Keep going after you hit pause. Everything else opens closed and is yours to grant, role by role.
What Claude itself brings
Any provider on this site can power the delegation above. These are the reasons to pick Claude in particular.
Claude models your agents can use
Prices and lineup verified September 2, 2026. In the product, the picker is fetched live from Anthropic on your own key — it never goes stale, and a custom model id always works if it validates.
$1/$5 per million tokens, 200K context — extraction is structured reading, and Haiku is accurate at it and the cheapest thing Anthropic sells
$2/$10, million-token context — the launch price Anthropic made permanent; the agent-workflow workhorse
$5/$25, million-token context — for the messiest documents and hardest calls
$10/$50 — Anthropic's frontier tier, reachable through the live picker if your key can call it (check the retention terms on frontier models first)
the picker asks Anthropic's Models API what your key can reach today — new Claudes appear without waiting on us
Media through Coordinator's pipeline: PDFs and images. The authority on current rates is Anthropic's pricing page.
Claude's API, as its users describe it
Recurring themes from public developer forums and reviews — the likes and the complaints — and how each plays out when the provider runs inside your own workspace.
- Opus 5's July 2026 launch — near-frontier capability at half the old flagship price — drew one of the year's biggest positive developer receptions.
- Sonnet 5's million-token context and adaptive thinking get credited for real agent-workflow fit, not benchmark theatre; Haiku 4.5 at $1/$5 per million tokens is the routinely named sweet spot for high-volume work.
- The Rate Limits API (April 2026) fixed a long-standing gripe — your code can now ask what its actual limits are instead of scraping the console.
Capacity is the recurring 2026 complaint: platform-wide overload (529) spikes reliably follow big model launches, with several incidents this year.
Here: An agent here isn't married to one vendor. Keep a second provider connected and switching the brain mid-incident is a settings change — the roles, fences and workflows don't move.
Cost-tracking surprises made the rounds — viral threads about API spend far outrunning expectations on agent workloads.
Here: Every agent turn bills your own Anthropic key at Anthropic's prices, with usage attributed per agent in the audit trail — the spend is visible where the work happened, and Anthropic workspaces let you cap it at the key.
The June 2026 requirement of 30-day data retention on Anthropic's newest Fable/Mythos tier drew loud backlash; Anthropic announced a rollback on September 1, 2026.
Here: The models this page lists — Haiku 4.5, Sonnet 5, Opus 5 — were never in that covered tier and keep the not-retained-by-default posture. If you route agents to a covered model, read Anthropic's retention page first; policy here is moving week to week.
How Coordinator treats your Anthropic key
The section above is Anthropic's report card. This one is ours — the plumbing decisions that make handing an agent your API key boring instead of brave.
Your key is encrypted like every credential in Coordinator, and after connecting, nothing ever displays more than its last four characters.
Connecting is a live round-trip to Anthropic — a key that doesn't actually work can't be saved, so failures happen in settings, not mid-task.
Zero markup, no metering, no shared key anywhere in the system. Every agent turn bills your own account at the vendor's own prices.
Model choices come from Anthropic's Models API on your key, so new Claudes appear without waiting on us — a baked-in list exists only as an outage floor, and a custom model id always works.
From no key to a working agent in a few minutes
Create a key in the Anthropic Console under Settings → API keys, on a workspace with credits.
- 1
Sign in at console.anthropic.com (a Claude.ai subscription is separate — the API is billed on its own).
- 2
Open Settings → API keys and choose Create key.
- 3
Pick or create a workspace for it. A dedicated workspace lets you set a spend limit and revoke Coordinator's access without touching anything else.
- 4
Copy the key the moment it appears — the console never shows it again.
- 5
Under Settings → Billing, add credits. A brand-new organisation has a zero balance and every call fails until you do.
Key verified — a live call to Anthropic confirmed it before anything was stored. Only the last four characters are kept visible.
Settings → AI: pick Anthropic (Claude), paste the key. A live call to Anthropic verifies it before anything is stored.
Fetched live from your key — never a stale list. Custom model ids work too.
Choose a default model from your key's live catalogue — or set one per agent later.
Billed per token on your own account. Claude Haiku 4.5 is the cheapest model that reads documents well; a one-page bill typically costs well under one US cent. Check the pricing page before committing — rates move.
The commonest failure is not a bad key: it's an unfunded workspace. If the connect test says the key was rejected but you're sure it was copied correctly, check the credit balance first.
Every agent turn bills your Anthropic account at Anthropic's prices. Coordinator adds no markup and never holds a shared key — connect-time validation is a live round-trip against your own credential.
Claude + Coordinator, asked directly
Any chat model your Anthropic key can reach — Haiku 4.5, Sonnet 5 and Opus 5 are offered by default, the live picker lists what your key sees, and a custom model id always saves if it validates.
No. Coordinator is free. Your Anthropic key is billed by Anthropic directly, at their published prices, with zero platform markup.
Yes — natively. Claude accepts multi-page PDFs as documents, so bill extraction works on the file your vendor actually sent, not a degraded screenshot of it.
They're complementary. An Anthropic key makes Claude power agents inside Coordinator; our MCP server lets your Claude apps operate Coordinator from outside. You can use either or both.
Swap the brain, keep the team
Your agents aren't built out of Claude — they're built out of roles, permissions and workflows. The model behind an agent is a setting: change it in a minute and the team, the history and the fences all stay put. Every provider we support gets the same treatment, and the same honest page:
Put Claude on the payroll
Coordinator is free — the only bill is the one Anthropic already sends you.
