On 2026-10-30 the server answered initialize and tools/list without a sign-in. First answer in 198 ms.

• Its tools do none of the product's use cases we checked: run a whole household during grid outages; store solar power for use after sunset; shift grid electricity use away from peak-price hours.
• Checked on 3 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• search

  Search the Oxbox Energy website for stationary batteries, chargers and DC power: product pages, datasheets, discharge tables, manuals, SDS and technical articles. Ask in plain words, e.g. "12 V gel battery for solar" or "OPzS 2V cell…

• fetch

  Read the full text of one result from search (a web page, a PDF, or a product series) with its link. A discharge table returns its figures once it has been checked against its datasheet, otherwise the link and page.

• find_series

  Find a stationary battery or product series that Oxbox Energy offers by chemistry (VRLA gel, AGM, flooded, pure lead, lithium), nominal voltage (2 V, 6 V, 12 V, 48 V ...) or application (telecom, utility, solar, UPS, switchgear). Returns…

• get_documents

  List the documents Oxbox Energy publishes for a series, or of one type across the site: datasheet, discharge_table, manual, sds, certificate, standard, brochure, technical_paper, warranty. Third-party documents are linked at their source.

• quote_request

  How to ask Oxbox Energy for a quote or price: the address to write to, and what to include so the engineers can answer without a round of questions. It sends nothing; the customer sends the request themselves.

• sizing_tool

  Oxbox Energy has NO online sizing tool, and this connector cannot size a system. This says how to get one sized: the customer sends the load, runtime and voltage with a quote request and the engineers size it.
