📄 Description

Overview

Adds a Python integration page for langchain-toolstem (v0.1.0, live on PyPI), which wraps Toolstem's Finance and SEC EDGAR MCP servers as native LangChain tools with built-in x402 USDC micropayment support.

The package exposes 8 production tools:

  • Finance (create_finance_tools): get_stock_snapshot, get_company_metrics, compare_companies
  • SEC EDGAR (create_sec_tools): get_company_filings_summary, get_insider_signal, get_institutional_signal, get_material_events_digest, compare_disclosure_signals

Discovery (initialize / tools/list) is free; each tools/call costs $0.01 USDC on Base mainnet via x402. No API key or account registration is required.

This is the Python counterpart to the JavaScript integration in #3875.

Checklist

  • I have read the contributing guidelines, including the language policy
  • I have tested my changes locally using docs dev
  • All code examples reflect the package's documented public API (create_finance_tools, create_sec_tools, create_x402_httpx_client)
  • I have used root relative paths for internal links
  • I have updated navigation in src/docs.json if needed (not needed — individual tool pages are surfaced via the tools index, not enumerated in docs.json, consistent with #3875)
