README

Oyster MCP by usefulapi

Use your Oyster account from Claude, Cursor, or any MCP client. It reads team members, time off, expenses, contract changes, invoices and time sheets, and it approves or rejects time off and expenses only when you ask. Hosted, no local install: connect with your own credentials.

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

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://oyster.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http oyster https://oyster.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": {    "oyster": {      "url": "https://oyster.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 you sign in with your Oyster account.

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

On first connect you sign in to Oyster and approve access. A Company Admin must approve the access. No keys go in config files.

Pricing

PlanPriceLimit
Free$050 tool calls / month
Pro (per user)$9/mo or $90/yr (2 months free)10,000 tool calls / month
Pro+ (per user)$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 oyster_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 oyster_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 oyster_upgrade before then undoes the cancel. Or write to [email protected].
