The rule that runs get_opening_line safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Infersports, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_opening_line, this is the rule to start with:
get_opening_line is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Infersports, apply this rule, and every get_opening_line call is checked against it from then on.
Questions about get_opening_line
Get the opening odds (初盘) for a fixture, paired with the current price, in ONE call. Resolves the fixture, then for each book returns its true opening (first-seen) quote alongside the current quote — so you can read movement directly. For 1x2 that's a price move; for totals/AH compare line (the opening line) vs current_line to read the line move (the sharp book often opens days earlier). A market with no opening yet on file is omitted. Args: query: natural-language fixture, e.g. "Real Madrid vs Barcelona" or a single team. markets: optional filter — any of "1x2", "asian_handicap", "totals". bookmakers: optional filter — bookmaker keys, e.g. ["pinnacle", "crown"]. period: optional — "full_time" or "half_time" (default: both). format: odds format — decimal | hk | malay | american | indonesian | probability. sport: optional filter — "football" or "basketball". date: optional UTC date "YYYY-MM-DD" to disambiguate same-name fixtures. On an ambiguous query, status is "ambiguous" and ask_user carries a disambiguation prompt — do not assume a match. Best-effort: a book/line with no opening on file is omitted. It is categorised as a Read tool in the Infersports MCP Server, which means it retrieves data without modifying state.
