Financial data MCP server for Claude, Cursor, and Continue

Jintel runs a hosted Model Context Protocol (MCP) server at https://api.jintel.ai/mcp over the Streamable HTTP transport. It exposes 15 typed finance tools that any MCP-compatible runtime — Claude Desktop, Cursor, Continue, Cline, Zed, Windsurf, Raycast AI, the OpenAI Responses API, LangChain, LlamaIndex — can call natively, with the same schema and the same Bearer / x402 auth.

What you get​

  • 15 tools covering market quotes, batch entity enrichment, regulatory filings (10-K / 10-Q / 13F / Exhibit 21), OFAC sanctions screening, macro indicators (GDP / CPI / interest rates / FRED), technicals (RSI / MACD / Bollinger Bands), news, social sentiment, short interest, campaign finance, S&P 500 valuation multiples, and the full GraphQL fan-out for nested queries the catalog doesn't pre-bake.
  • Streamable HTTP transport — no local install for the remote variant; agents discover the server at /.well-known/mcp.json and the richer server card which inlines the full tool catalog with input schemas.
  • Read-only annotations on every tool (readOnlyHint: true, destructiveHint: false) so Claude Desktop and other hosts can skip the human-confirmation prompt that fires for unannotated tools.
  • Free initialize and tools/list so agents can browse the catalog before binding a key — the only paid path is tools/call.

Why MCP​

  • Native tool calls. Claude / Cursor / Continue treat MCP servers as first-class function-calling targets. No glue code, no JSON parsing, no rate-limit retries — the runtime handles all of it.
  • Typed inputs. Every tool ships a JSON Schema for its arguments. Agents see exactly which tickers, dates, or filter knobs are valid before issuing the call.
  • Discoverable catalog. tools/list returns descriptions and schemas. Combined with /.well-known/mcp.json, agent registries (orank, openrouter, mcp.so) can index Jintel without bespoke connectors.

Auth options​

  • Bearer API key — Authorization: Bearer jk_live_…. Issue via Google OAuth or wallet sign-in (/auth/siwx/verify).
  • x402 pay-per-query — drop the Bearer header, sign each tools/call payment quote with EIP-3009 USDC on Base mainnet. No signup; the wallet identifies the caller.
