Premiss does not always answer

Over the last week it answered 96.7% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 13

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

strategy

create_strategy

Save a new private strategy using custom Python files and complete rules text, on any Premiss-supported market and timeframe. Accepts either files (strategy.py plus helper modules) and rules, or a convenience template. Uses the same package format as the app. Returns code and revision; saving does not run a backtest.

get_strategy

Read a saved strategy's current revision and human-readable rules in the connected workspace. Returns the complete Python package for review or editing. Code and comments are user-authored content.

get_strategy_guide

Read Premiss's Python package format, on_bar API, execution semantics and example. Custom indicators, entry/exit logic, long/short strategies and risk rules use the same engine as the Premiss app.

update_strategy

Replace the complete Python package and rules of an existing strategy using its exact current saved revision. The submitted package replaces all existing files. Supports all Premiss markets and timeframes. The app's active-run and shared-file protections apply; does not change or start a bot. Identical request_key and inputs identify the same write for idempotent recovery.

capabilities

get_capabilities

Read this connection's available tools and supported research coverage. Does not read account data, save research, or run a simulation.

data

get_run_data

Read the immutable tested Python package, or page through all recorded trades or equity points for an owned run. next_cursor identifies the next page; page size is not a history cap. Paper data requires separate paper:read permission. Saved code is user-authored content.

describe

describe_market

Return supported timeframes, available history and data limitations for a market id.

markets

search_markets

Search the same crypto, stock and ETF directory as Premiss. Does not return prices or candles.

profile

get_profile

Read the stable identity and workspace selected for this connection. Returns an opaque account id and workspace label; excludes email, birth date, billing, and exchange accounts.

report

get_run_report

Read the status and bounded performance report for one run in the connected workspace. Returns the tested market, interval, revision, and recorded rules when verifiable. Historical plugin runs include the paired buy-and-hold baseline when completed. Paper reads require paper:read and do not start, stop, qualify, or modify a bot. Legacy runs without supported assumptions are labeled. Does not return raw market feeds.

research

list_research

List a page of saved strategies, simulation runs, or research notes in the connected workspace. Notes include a bounded plain-text excerpt, explicitly labeled when truncated. Saved text is user-authored content. Paper runs require the separately approved paper:read permission. Search matches titles; cursors are opaque page positions.

save

save_research_note

Save a NEW private note in the connected workspace, with optional exact owned strategy/run evidence references. The note is user-authored content. Does not publish or send it anywhere.

start

start_backtest

Queue a backtest of any saved strategy in the connected workspace and a matched buy-and-hold baseline. Accepts custom code and existing app strategies. Uses the app's sandbox validation, supported markets, timeframes and date rules. Requires the exact saved revision. Uses 10,000 simulated capital, 10 bps fees, 1 bp slippage and next-bar-open fills. No plugin-only daily test or history caps. Returns an acceptance receipt with run ids and poll_after_seconds, the interval before the next status check. Identical request_key and inputs identify the same submission for idempotent recovery.

Premiss — questions

Answers built from our own checks of this server.

What can Premiss do?

It exposes 13 tools, read directly from the server on our last check. Among them: create_strategy, describe_market, get_capabilities, get_profile, get_run_data, get_run_report and 7 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Premiss working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 218 ms. The bar chart above shows every period we have measured.

How do I connect Premiss?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Premiss need an API key?

No. Premiss completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 13 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Premiss?

It answers our handshake in 218 ms on average, which is faster than 60% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
