description: The Tesser MCP server exposes every public Tesser API endpoint as a tool that AI agents can
  discover and invoke over Streamable HTTP. It is also modeled in the OpenAPI as the POST /v1/mcp operation
  (operationId mcp_server). Tools map 1:1 to the REST operations (Accounts, Counterparties, Tenants, API
  Keys, Payments, Treasury, Currencies, Networks, Organizations, Users).
authentication:
  model: oauth2-client-credentials (Auth0), same credentials as the REST API
  methods:
  - name: oauth-discovery
    recommended: true
    detail: 'Serves RFC 9728 protected-resource metadata at /.well-known/oauth-protected-resource; a 401
      returns a `WWW-Authenticate: resource_metadata` hint. MCP-authorization-spec clients (e.g. Cursor)
      run the OAuth flow and refresh tokens automatically.'
  - name: manual-bearer
    detail: 'Fallback for clients without OAuth discovery (e.g. Claude Code today): fetch a token via
      scripts/mcp-token.sh and pass it as a header.'
clients_documented:
- Cursor
- Claude Code
tools_note: Published server advertises tools dynamically from the API surface; the provider does not
  publish a static tool manifest. See the OpenAPI operations (58) as the canonical tool set.
