常见问题

Iposignal 安全吗?

它在 3 项适用的基础检查中通过了 3 项。我们没有阅读代码。在添加密钥或令牌之前,请先看看这个服务器要求哪些权限,并使用只具备所需权限的密钥。

它需要哪些密钥或代码?

注册中心没有列出必需的密钥,不过有些服务器会在首次使用时要求你登录。

它在我的电脑上运行还是在云端?

它在作者的云端运行。通过互联网连接,无需安装,但你发送的内容会经过作者的服务器。

它还在维护吗?

GitHub 仓库最后更新于–,最新版本(1.3.0)于2个月前进入注册中心。

哪些应用可以使用它?

支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接,所以接受远程 MCP 服务器的应用也可以使用,例如开启开发者模式的 ChatGPT。

有什么可以替代它?

IPOSignal — MCP server, A2A agent card, x402 API

Machine-readable IPO intelligence from iposignal.xyz: deal terms, SEC filings, AI research, proprietary market and social sentiment, and live valuation metrics for any US-listed company.

Three ways in, all against the same data:

SurfaceEndpointAuthCost
MCPhttps://iposignal.xyz/api/mcpnonefree
A2Ahttps://iposignal.xyz/.well-known/agent-card.jsonnonediscovery free, calls priced below
HTTP + x402https://iposignal.xyz/api/agent/*nonepay-per-request in USDC on Base

No accounts, no API keys, no rate-limit tiers. This repo holds the public metadata, connection docs and examples — the product source is private.


MCP server

Streamable HTTP. Free and ungated: the MCP surface mirrors the paid HTTP endpoints at no cost.

claude mcp add --transport http iposignal https://iposignal.xyz/api/mcp

Or in a client config:

{

"mcpServers": { "iposignal": { "type": "streamable-http", "url": "https://iposignal.xyz/api/mcp" } } }

Tools (4)
ToolReturns
get_ipo_snapshotFull IPO company profile — deal terms, pricing range, expected market cap, SEC registration and prospectus details, offering structure, lifecycle timeline, IBKR indicative borrow fee. Includes AI research with valuation models, competitor benchmarking, underwriter ratings, board analysis and risk factors where available. One of companyId, symbol or cik.
get_ipo_sentimentProprietary daily IPO-market sentiment score, −100 (extreme bearish) to +100 (extreme bullish), with trend over the last N days. Identifies favourable IPO windows and overall appetite for new listings.
get_company_metricsLive valuation metrics for any US-listed company, not just IPOs: SEC XBRL companyfacts TTM fundamentals plus latest close → P/E, P/S, EV/Revenue, EV/EBITDA, PEG, linear yields, net-debt/EBITDA, margins, YoY growth. One of symbol or companyName.
get_ipo_social_sentimentAggregate X/Twitter sentiment for a specific IPO, −1 to +1, with label, post tallies and a one-line summary. Aggregate signal only, not the underlying posts.

Test it live in the Glama MCP inspector by pasting the endpoint URL.


A2A agent card

Served at both paths during the spec transition:

  • https://iposignal.xyz/.well-known/agent-card.json — current spec
  • https://iposignal.xyz/.well-known/agent.json — legacy (v0.2 and earlier)

Discovery manifest: https://iposignal.xyz/api/a2a

Six skills, one free (lookup_companies_with_financials), five paid via x402.


Paying with x402

Endpoints under /api/agent/* are machine-payable using the open x402 protocol. USDC on Base mainnet (eip155:8453).

  1. Call the endpoint. Unpaid requests return HTTP 402 with a PAYMENT-REQUIRED header describing price, asset, network and recipient.
  2. Your x402 client signs the payment and retries with a PAYMENT-SIGNATURE header.
  3. The payment is verified and settled on-chain, then the data returns with a PAYMENT-RESPONSE settlement header.
Prices

Live values are always in the agent card under payment.prices — read them there rather than hardcoding.

EndpointPrice
GET /api/agent/companies?q={query}free
GET /api/agent/ipo/by-symbol/{symbol}$0.01
GET /api/agent/financials/by-symbol/{symbol}$0.01
GET /api/agent/company-metrics?symbol={symbol}$0.02
GET /api/agent/ipo-sentiment$0.01
GET /api/agent/social-sentiment?symbol={symbol}$0.01
