About Basis Theory MCP by usefulapi

Basis Theory MCP by usefulapi is a hosted MCP server for reading data from a Basis Theory PCI vault. It provides access to token metadata, applications, audit logs, proxies, and tenant information without a local installation.

Key features

  1. 01List, search, and inspect tokens
  2. 02View applications and configured key identity
  3. 03Read audit logs and entity types
  4. 04Inspect proxies and reactors
  5. 05Review permissions, roles, tenant members, and usage

Use cases

  1. 01Search vault tokens and inspect their metadata
  2. 02Review audit logs for vault activity
  3. 03Check tenant usage, roles, and members

MCP support

Exposes read-only Basis Theory vault and tenant tools to MCP clients, including token, application, audit log, proxy, and usage queries. The hosted server uses OAuth sign-in with Basis Theory credentials.

Configuration

Remote servers need no local install. Pick your client, then copy the config or install in one click.

Details

From the project README

Basis Theory MCP by usefulapi

Read token metadata, applications, audit logs, proxies and usage in the PCI vault. Hosted, no local install.

Live endpoint: https://basis-theory.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://basis-theory.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http basis-theory https://basis-theory.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:
{
  "mcpServers": {
    "basis-theory": {
      "url": "https://basis-theory.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 Basis Theory credentials.

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

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

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
