io.github.Sofiia7/actually
Matches news to Polymarket markets and returns the market's probability. Optional capped trading.
The current version, v0.1.7, was published to the official MCP registry on 2026-08-26. It is distributed as actually-mcp-server on npm, filed under Other by this index, and declares 8 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).
Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less
uv tool install mcpindex-gate && mcpindex-config-wireVerdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

That verdict was true at screening time (snapshot 2026-08-26).
Contracts can change after screening, with no version bump. The gate pins io.github.Sofiia7/actually’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

POLYMARKET_PRIVATE_KEYOptional. Your own Polygon EOA private key. Enables the trading tools (place_order, sell_order, cancel_order, get_open_orders, get_positions). Omit to run signal-only, which needs no key and no wallet.
ACTUALLY_MAX_ORDER_USDOptional. Per-order USD cap for the trading tools (default 100). Enforced server-side against the market's own price, so a caller cannot understate an order to slip past it.
ACTUALLY_DAILY_LIMIT_USDOptional. Rolling UTC-day USD cap shared by place_order and sell_order (default 500). Held in a persisted ledger, so it survives restarts.
ACTUALLY_ENABLE_REDEEMOptional. Set to exactly 'true' to additionally register redeem_position. A second opt-in beyond the private key, because it submits a real on-chain transaction through Polymarket's relayer and is still in testing.
ACTUALLY_SEARCH_FALLBACKOptional. Set to exactly 'true' to let check_news fall back to Polymarket's own market search when nothing in the cached set matches. Off by default: the query is built from the caller's text and leaves the machine.
ACTUALLY_SPEND_STATE_PATHOptional. Where the spend ledger is stored (default ~/.actually-mcp-server/spend-guard.json).
ACTUALLY_WORKER_URLOptional. Only if you run your own Cloudflare Worker instead of the shared default.
ACTUALLY_WORKER_SECRETOptional. Shared secret for your own Worker. Not a private credential: the default one ships inside every client by design.
