Ten read-only tools over the Model Context Protocol: the live market catalogue, per-market price and leverage limits, venue health and settlement chain, the engine fee ladder, the round-trip cost a trade has to beat with its provenance, a cost gate for any claimed edge, an honest way to combine agreeing signals, a route comparison against a public order book, an indicative estimate that is labelled derived and never firm, and the oracle price beside an external mid. Install it with one line and your agent reads Gryps.
§1Capabilities
Serves live market state: symbols, leverage limits and the fee ladder are read from the venue at call time, never hardcoded. When pricing changes, your agent sees a data change, not a broken assumption.
Answers the only question that matters before a trade: what it costs. The friction floor is decomposed into fees and spread with full provenance, and it says when it is a lower bound rather than pretending to be all-in.
Cost-gates a claimed edge from any signal source without ever saying the signal is true, and refuses to count five correlated sources as five confirmations.
§2Design
MCP-native. Standard Model Context Protocol server. Works with Claude Desktop, Claude Code and any MCP-compatible client: one config entry and the tools appear.
Every answer names its source. Each response carries the endpoint it read, the time it read it, and its limitations, so your agent can reason about trust and staleness instead of assuming them.
Read-mode first. The open build is deliberately read-only. Write mode ships behind the same adapter seam once the v2 engine write path is stable, with no re-integration required.
§3Availability by tier
| Open | Read-mode server, full source, non-commercial license. |
| Pro | Write mode plus a hosted endpoint with SLA. |
| Institutional | Dedicated instance, custom tools, commercial license. |
Indicative until launch.
§4 · Stated plainly
Read-only, by construction. Spread is not yet measured on v2, so the friction floor is a lower bound and says so. Whether the engine fee is per side or round trip is unverified; the server assumes per side and doubles it, and carries that assumption in every response.
