These are gaps on our side, not findings about this hosted endpoint. We only credit what we can confirm, so a category made up entirely of them scores 0.

  • Authorization in Endpoint SecurityAuthorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  • HTTPS in Endpoint SecurityHTTPS enforcement could not be verified: the plaintext port redirected somewhere other than https, so enforcement is unproven.

MCP tools · 19 exposed · ~3,166 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Install

How do I install the SOS Inventory MCP by usefulapi server?

SOS Inventory MCP by usefulapi is a hosted endpoint at https://sos-inventory.usefulapi.io/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Common questions

What is the SOS Inventory MCP by usefulapi server?

SOS Inventory MCP by usefulapi is listed in the public MCP registry as io.usefulapi/sos-inventory. Read SOS Inventory stock and orders; create customers, items and purchase or sales orders. This page covers its hosted endpoint (https://sos-inventory.usefulapi.io/mcp).

Is the SOS Inventory MCP by usefulapi server safe to use?

SOS Inventory MCP by usefulapi scores 18 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 SOS Inventory MCP by usefulapi server expose?

SOS Inventory MCP by usefulapi exposes 19 tools: sosinventory_list_items, sosinventory_get_item, sosinventory_get_item_bom, sosinventory_list_customers, sosinventory_get_customer, and 14 more. Their descriptions and schemas cost roughly 3,166 tokens of context every time the server is loaded.

Does the SOS Inventory MCP by usefulapi server require authentication?

Its publisher declares no required credentials for SOS Inventory MCP by usefulapi. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

Is the SOS Inventory MCP by usefulapi server still maintained?

SOS Inventory MCP by usefulapi is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What did VerifyMCP test on the SOS Inventory MCP by usefulapi server?

VerifyMCP ran 4 checks on SOS Inventory MCP by usefulapi, covering TLS certificate, HSTS header, DNSSEC and Transport. 7 items could not be completed, a gap on our side rather than a finding about SOS Inventory MCP by usefulapi: Authorization, HTTPS, Schema quality, Stability and 3 more. 5 categories score 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
