API keys and plans
Issuing and revoking an API key for the MCP server, and what each plan holds.
API keys
An API key lets an AI client reach your workspace through Sondo's MCP server. Each client gets its own key, and you can revoke any of them at any time without touching the others.
Keys live on the Integrations page in the dashboard, alongside the endpoint every client connects to.
The one endpoint every client connects to is https://usesondo.com/api/mcp.
Issuing a key
Click Create API key and give it a label. Name it after the client you are connecting, for example "Claude Code on my laptop", because the label is the only way you will tell your keys apart later.
The key is then shown once. Copy it before you close the dialog: Sondo stores only a hash of it, so a lost key can be re-issued but never recovered. The dialog deliberately will not close on Escape or a stray click while the key is on screen.
Every key starts with sondo_sk_. Treat it like a password. It grants access to the conversations
in that workspace.
You can hold up to twenty active keys per workspace. Revoked keys do not count.
Revoking a key
Revoke on any row. Any client using that key stops working immediately.
A revoked key stays in your list as a record and cannot be un-revoked. To reconnect that client, issue a new key.
The table also shows when each key was created and when it was last used, so an unused key is easy to spot before you revoke it.
Plans
Every feature is on every plan. They differ only in how much they hold.
| Plan | Monthly | Yearly | Workspaces | Knowledge Base |
|---|---|---|---|---|
| Solo | $12 a month | $120 a year | 1 | 5,000 pages |
| Pro | $29 a month | $290 a year | 5 | 15,000 pages |
A page is 2,000 characters of text, roughly one printed page.
Prices are in United States dollars and exclude tax. Paying yearly costs ten months rather than twelve.
If you need more than Pro holds, there is a Pro Max tier with unlimited workspaces and an unlimited Knowledge Base, arranged by email rather than bought online. The pricing page has the address to write to.
There is no trial and no free tier: your widget answers visitors while the subscription is active. If a payment fails, Sondo keeps answering while the card is retried rather than cutting your site off over a card that expired.
You can change plans or cancel at any time from your account page in the dashboard. Everything you added stays in place if you cancel, and comes back with the subscription.
