Overview

AI-generated overview

Hosted Unkey server that lets an assistant inspect and manage API keys, identities, permissions, rate-limit overrides and verification analytics.

What you can do
  • Check API health and look up keys by id or by plaintext secret
  • Read API namespaces, list keys under an API, and list identities with their metadata
  • List workspace permissions, roles, and rate-limit overrides per namespace
  • Run read-only SQL over key-verification analytics using public table aliases
  • Create APIs, keys and identities, update key settings and credits, revoke keys, and set rate-limit overrides
  • Report usage, request features, and manage the Pro or Pro+ subscription
When to use it
Useful when you want to ask questions about your Unkey workspace in natural language, such as which keys a customer holds, how many verifications passed recently, or which rate limits are overridden. Also suits issuing, updating or revoking keys and adjusting a single customer's limits without opening the Unkey dashboard.
Requirements
Remote streamable HTTP endpoint; no local install. Connect with the URL only and sign in through OAuth with your Unkey credentials on first connect; credentials are stored per user. A free plan allows 50 tool calls per month; paid plans raise the limit.
Before you install
Write tools create, change and revoke keys, identities and rate-limit overrides, and deleting a key permanently erases it when requested; confirm before running them. A newly created key's plaintext is returned only once. The server asks for your Unkey credentials at sign-in and proxies calls to Unkey. Usage is metered, and upgrades return Stripe checkout links that spend money; cancellations give no refund for the current period.

Installation

In SourceWeft

  1. Open Unkey MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Funkey/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

Unkey MCP by usefulapi

Manage API keys, identities, permissions, rate-limit overrides and verification analytics. Hosted, no local install.

Live endpoint: https://unkey.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://unkey.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http unkey https://unkey.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "unkey": {      "url": "https://unkey.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Unkey credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/unkey/

On first connect you'll paste your Unkey credentials. They are validated, stored per-user, and scoped to you — no keys in config files.

Pricing

PlanPriceLimit
Free$050 tool calls / month
Pro$9/mo or $90/yr (2 months free)10,000 tool calls / month
Pro+$39/mo or $390/yr (2 months free)100,000 tool calls / month

Each paid plan covers this server only. Ask your AI to run unkey_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with unkey_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with unkey_upgrade before then undoes the cancel. Or write to [email protected].

Check that the Unkey API is reachable and the root key works. The only GET in the v2 surface. Unkey: GET /v2/liveness.

Takes no parameters.

unkey_get_key

Fetch a key's metadata by its key id — name, owner, permissions, credits, rate limits and whether it is enabled. Read-only despite being a POST. Unkey: POST /v2/keys.getKey.

ParameterskeyIdrequireddecrypt

unkey_whoami_key
