Waveleta provides read-only market data to MCP clients, including crypto tickers and metadata, ranked radar signals, FX reference rates, energy commodities and early-access US equities history. Advisors and investment teams can use it for market context in client reviews and pricing inputs to research and trading workflows. Firm developers can connect the hosted feed to internal data and reporting tools.
Provides data. A read-only feed from one provider; it answers questions, doesn't act, and doesn't expect other servers alongside it. More on Source servers →All seven roles →
Vendor-reported coverage, refresh intervals and capabilities have not been independently verified.
The vendor states that this MCP server cannot place, change or cancel orders. The separate trading service described on the page is not an MCP capability.
Vendor-reported crypto ticker refresh is once per minute, FX rates are daily reference rates, and US equities history is early access. These feeds should not be assumed to provide real-time execution pricing.
Vendor-reported pricing is €0.002 per successful tool call from a prepaid balance after €2 starter credit. Connecting, listing tools and failed calls are not charged.
The vendor documents API keys stored in client configuration files and warns against committing them to repositories. The source does not specify MCP request retention or data-handling policies.
The vendor reports that OAuth is not yet offered, limiting ChatGPT custom connector support. Claude Desktop requires the mcp-remote bridge and Node.js.
Start with read-only scopes and keep client-side approval prompts on until the connection is proven.

How to connect Waveleta Market Data
Step 1
Remote server: paste a URL
Waveleta Market Data publishes a remote (Streamable HTTP) endpoint, so nothing is installed locally. Add it as a custom connector in Claude, ChatGPT or your IDE and paste the endpoint below.
Create a key in the vendor's dashboard and store it as an environment variable in your client config. Never paste it into a chat window.
Step 3
Verify, then widen access
Restart your client, confirm the server's tools appear, and run one read-only question first. Keep client-side approval prompts on for any tool that can write, trade or send. Confirm with your firm's compliance policy before connecting systems holding client data.
Trade & RebalanceCustody & ClearingMarket & Financial Data
Read-only: for the proposed sells in <account>, review tax lots at the custodian and flag short-term gains, large realised gains, and any purchase in the last 30 days that could create a wash sale. Then use market-data tools to value each lot at the latest available price and to check for splits, mergers or other corporate actions that would change basis or share count. Output Symbol / Lot / Acquired / Basis / Market value / Gain-loss / Flag / Source. Do not place or modify trades. Tell me where the data may be delayed or incomplete.

Scenario comparison brief
A side-by-side read on two planning scenarios.
Financial PlanningFinancial PlanningMarket & Financial Data
Read-only: compare the existing plan for <client name> against the scenario <describe change, e.g. retire two years earlier>. Pull the plan's stored return, inflation and yield assumptions, then use market-data tools to show current comparable figures for the same inputs. Present outcome differences, an assumptions table of Plan assumption / Current market reading / Source / Date, and which assumption the result is most sensitive to. State every assumption explicitly. Do not save, overwrite or publish any scenario in the planning system.

Market context talking points
Three to five neutral talking points on recent market moves.
Client Review Meeting PrepWealth PlatformsMarket & Financial Data
Read-only: pull <client name>'s current holdings and sector or asset-class weights from the wealth platform, then use market-data tools to explain what moved those specific exposures over the last quarter. Return three to five neutral talking points, each tied to a holding or weight and to the market data behind it. No forecasts, no recommendations to buy or sell, no performance promises. Cite the source and date for both the holdings figure and the market figure so I can verify before I use it with a client.
