prop-rules-mcp

An MCP server that answers "can I take this trade?" instantly, against a specific prop firm's actual rules — drawdown remaining, max position size, consistency rule, daily loss limit — instead of a trader doing that math by hand mid-session.

The problem this solves

Prop firm rules vary firm-to-firm and account-size-to-account-size (trailing vs. static drawdown, consistency rule thresholds, per-instrument contract caps), and breaking one silently fails an evaluation or a funded account — often discovered only after the fact. This puts the actual rule set behind a tool call instead of a tab of firm PDFs.

Tools

check_account_status

Pass/fail state for a live evaluation or funded account: how close to each limit, and what actions are safe right now.

get_drawdown_remaining

Exact drawdown headroom left before account breach, trailing or static.

get_max_position_size

Max allowed contracts for a given instrument, per firm and account-size rules.

check_consistency_rule

Checks whether a trader's best single day exceeds the firm's allowed percentage of total profit — the rule that quietly disqualifies otherwise-passing accounts.

get_firm_rules

Full rule set for a specific prop firm and account size, as structured data.
