WHAT IT DOES

What convert_betting_odds does on Calcgrid

AI agents use convert_betting_odds to create or update resources in Calcgrid, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Calcgrid environment.

Parameter	Type	Required	Description
`odds`	string	Yes	Odds in any format: American +150 or -200, decimal 2.50, fractional 3/2 or 3-2, or evens.
`stake`	number	—	Stake used for the profit and return outputs (any currency).
`format`	string	—	Format of the odds input. Auto: a/b or a-b with digits on both sides is fractional, a sign or an integer of 100 or more is American, anything else is decimal.

Parameters from the server's own tool schema.

RISK

Why convert_betting_odds is rated Medium

An AI agent can call convert_betting_odds faster than any human can review: one bad instruction and it creates or modifies resources in Calcgrid by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs convert_betting_odds safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Calcgrid, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For convert_betting_odds, this is the rule to start with:

convert_betting_odds Rate-limited

convert_betting_odds stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about convert_betting_odds

What does the convert_betting_odds tool do? +

Use this when you have odds in one format and need the other two, the implied probability of a price, or the payout of a stake at those odds. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when you need the combined price of several selections (use parlay-odds), the value of a bet given your own probability estimate (use bet-expected-value), or a bookmaker's margin across a whole market (use arbitrage-bet). Mathematics only; not gambling advice. What it computes: Converts betting odds between American (moneyline), decimal (European) and fractional (UK) formats, auto-detecting the input format, and reports the implied probability, profit and total return for a stake. Inputs: odds (string); format (enum, optional); stake (number, optional). Complete JSON argument examples: {"odds":"+150"} | {"odds":"-200","format":"auto","stake":100} Outputs: american, decimal, fractional, implied_probability_percent [%], profit_on_stake, total_return, detected_format. Formula: decimal = 1 + american/100 (american > 0) or 1 + 100/|american| (american < 0); decimal = 1 + a/b (fractional a/b); american = +100·(decimal − 1) if decimal ≥ 2, else −100/(decimal − 1); fractional = (decimal − 1) reduced with the GCD; implied_probability_percent = 100/decimal; total_return = stake × decimal Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/odds-converter with the same JSON input fields. Do not guess another /api/* path. Docs: https://tttkmbb.com/gaming/odds-converter.md. It is categorised as a Write tool in the Calcgrid MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I block convert_betting_odds completely? +
