## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-04.

- **Endpoint Security**: 94/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
  - The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1564 tokens (~142/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (11)

### `get_inventory_overview` (~59 tokens)

Get inventory overview

Use this when the merchant asks for a broad inventory health check, an executive summary, their urgent/excess/no-demand counts, inventory valuation, or current PO workload. Requires a connected Forthcast store; the assistant will prompt to sign in.

Takes 3 to 365 monthly, weekly or daily totals (oldest first) and returns the next periods with an 80 percent range, the model used (Holt-Winters seasonal, damped trend, Croston for intermittent demand, or moving average) and why.

## Common questions

### What is the Forthcast Inventory MCP server?

Forthcast Inventory is an MCP server listed in the public MCP registry as io.forthcast/inventory. Demand forecasts, reorder points, order quantities and inventory health for Shopify stores. This page covers its hosted endpoint (https://app.forthcast.io/mcp).

### Is the Forthcast Inventory MCP server safe to use?

Forthcast Inventory scores 80 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Forthcast Inventory MCP server expose?

Forthcast Inventory exposes 11 tools: get_inventory_overview, get_reorder_recommendations, find_inventory_items, get_inventory_item, list_purchase_orders, and 6 more. Their descriptions and schemas cost roughly 1,411 tokens of context every time the server is loaded.

### Does the Forthcast Inventory MCP server require authentication?

Yes. Forthcast Inventory asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the Forthcast Inventory MCP server still maintained?

Forthcast Inventory is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
