NuMetric MCP Server
Read your NuMetric accounting, reports & documents from any MCP client.
Website · Documentation · Privacy · Support
A Model Context Protocol server for the NuMetric.work POS / ERP / accounting platform. It exposes your live business data as read-only tools, so an AI assistant answers from your actual books instead of guessing.
It never creates, edits, or deletes anything.

}Any other MCP client
Point it at the Streamable-HTTP endpoint above. The server advertises OAuth 2.1 discovery (RFC 9728 / RFC 8414), so compliant clients start the sign-in flow automatically.
Requirements
- A NuMetric.work account (any plan).
- Your region (e.g.
JO,SA, or Global). - An MCP client that supports remote servers with OAuth.
Access follows your existing NuMetric permissions — you only ever see the modules you already have
rights to. A tool you lack permission for returns SCOPE_REQUIRED rather than data.
Choosing a business
If your account has more than one business, ask your assistant to list your businesses, then select one ("list my businesses" → "use Acme Trading"). The choice sticks for the session and you can switch anytime. Single-business accounts are selected automatically.

Machine-readable schema for every tool: mcp-schema.json.
Read-only by design
Every tool carries readOnlyHint: true. There is no payment, transfer, trade, create, edit, or delete
tool in this server — not gated, not present. That is meant literally: as of 0.9.0 the write code was
removed from the deployed server rather than left behind a feature flag, so there is no configuration
that turns it on. Read-only tools run without per-call confirmation in clients that honor the hint.
Verified vs. Guarded
Every computed figure carries a confidence value:
- Verified — the figure comes straight from NuMetric's accounting engine and reconciles.
- Guarded — NuMetric flagged it as possibly stale or unbalanced, or it is a snapshot rather than a live read. Your subscription entitlements are always Guarded: NuMetric provides no way to re-read them, so they reflect the moment you connected and refresh when you reconnect. Usage figures are the exception worth knowing about — seat counts come from NuMetric directly, while the transaction count is measured from your ledger and is reported with its basis.
The server instructs connecting assistants to hedge on Guarded figures rather than present them as final. Claude reports what your books say; it does not recompute your accounting itself.
Authentication
OAuth 2.1 with PKCE (S256). You sign in on NuMetric's own page — your credentials are exchanged for a token server-side and held in an encrypted vault. The assistant only ever holds a short-lived token scoped to this server; your NuMetric password and API token never reach it.
Your business identity and region are bound to the authenticated principal and are never passed by the AI caller. Disconnect anytime from your client's connector settings.
Privacy & security
- Read-only — no tool can move money or change your data.
- Credentials never reach the AI client.
- Encrypted in transit and at rest.
- Every read is rate-limited per principal and written to an audit log.
See the Privacy Policy and Terms & Conditions.
Troubleshooting
| Message | Meaning |
|---|---|
NO_BUSINESS_SELECTED | Run "list my businesses", then select one. |
SCOPE_REQUIRED | Your NuMetric user lacks access to that module — ask your account admin. |
| A figure marked Guarded | Treat it as unconfirmed rather than final. |
STATEMENT_UNAVAILABLE | That statement type isn't available yet for your account. |
