Readme

@openfinclaw/core

Core logic for OpenFinClaw — DeepAgent client, strategy tools & shared types. Zero framework dependencies.

npm License: MIT

This is the library core used by @openfinclaw/cli (the MCP Server + CLI). Install this directly only if you are building your own MCP wrapper, custom agent integration, or calling the OpenFinClaw DeepAgent / Hub APIs from code.

🧪 Try DeepAgent online first → https://hub.openfinclaw.ai/en/chat — no install required.

👉 For most users, install @openfinclaw/cli instead.

Install

npm install @openfinclaw/core
# or
pnpm add @openfinclaw/core

Node 18+ (ESM only). TypeScript types are bundled.

What's inside

Two tool groups, both exported as pure functions + JSON schemas. Bring your own MCP SDK / agent framework. Both groups share a single fch_ API key (Authorization: Bearer fch_...)—DeepAgent traffic is routed through the Hub Gateway, strategy traffic hits commons-hub directly.

Group Tools Auth
DeepAgent (one-stop quant agent) fin_deepagent_health · _skills · _threads · _messages · _research_submit · _research_poll · _research_finalize · _status · _cancel · _backtests · _backtest_result · _packages · _package_meta · _download_package Authorization: Bearer fch_... (Hub Gateway)
Strategy (advanced local FEP v2.0 workflow) skill_publish · skill_validate · skill_fork · skill_leaderboard · skill_get_info · skill_list_local · skill_publish_verify Authorization: Bearer fch_... (Hub)

DeepAgent covers market data, analysis, deep reports, strategy generation, backtesting and paper trading — a one-stop quant-trading agent you can reach from any coding assistant via MCP.

Quick example

import { resolveOpenFinClawConfig, executeDeepagentResearchSubmit } from "@openfinclaw/core";

// Picks up OPENFINCLAW_API_KEY from env / ~/.openfinclaw/config.json automatically.
const config = resolveOpenFinClawConfig();

const { taskId } = await executeDeepagentResearchSubmit(
  { query: "Research NVDA momentum over the last 90 days, propose a strategy, backtest 1y" },
  config,
);
// Then poll with executeDeepagentResearchPoll / finalize with executeDeepagentResearchFinalize

Every tool follows the same signature:

execute<ToolName>(params: Params, config: OpenFinClawConfig): Promise<Result>

Each tool also ships a paired JSON schema (e.g. deepagentResearchSubmitSchema) for wiring into any MCP SDK, OpenAI function-calling, or custom validation layer.

Configuration

import { resolveOpenFinClawConfig, type OpenFinClawConfig } from "@openfinclaw/core";

const config: OpenFinClawConfig = resolveOpenFinClawConfig({
  apiKey: "fch_...",          // unified key for both strategy & deepagent
  allowMissingApiKey: true,    // diagnostic mode (used by `doctor`)
});

Resolution order (highest priority first):

  1. options.apiKey
  2. OPENFINCLAW_API_KEY env
  3. ~/.openfinclaw/config.json#apiKey

Override the config file path with OPENFINCLAW_CONFIG_PATH. The DeepAgent base URL defaults to https://gateway.openfinclaw.ai/api/v1/agent and can be overridden with DEEPAGENT_API_URL for staging.

DeepAgent streaming (optional)

For terminal-side true token-by-token streaming, use parseDeepAgentSSE directly:

import { parseDeepAgentSSE } from "@openfinclaw/core";

const resp = await fetch(`${config.deepagentApiUrl}/threads/${threadId}/runs`, {
  method: "POST",
  headers: {
    Authorization: `Bearer ${config.apiKey}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({ message: "Analyze BTC trend" }),
});

for await (const event of parseDeepAgentSSE(resp.body!)) {
  if (event.type === "TEXT_DELTA") process.stdout.write(event.data.delta);
}

For MCP server contexts (where token-by-token rendering isn't supported by most clients), use the three-step submit/poll/finalize tools instead — they return immediately and let the agent poll for progress.
