Claude Desktop MCP Server for Stock Market Data

Claude Desktop

Claude Desktop connects to the Equibles MCP server as a custom connector — sign in over OAuth and there's no key to manage.

1. Install Claude Desktop

Download the desktop app from claude.com/download and sign in.

2. Add the Equibles server

Add Equibles as a custom connector over OAuth:

Open Settings → Connectors.
Click Add custom connector.
Paste the server URL:
```
https://mcp.equibles.com/mcp
```
Click through to sign in to Equibles and approve access. Claude Desktop holds a short-lived OAuth token — no key to copy.

Prefer an API key? Instead of signing in, paste a URL with your key from /dashboard/apikeys:
https://mcp.equibles.com/mcp?api_key=eq_your_api_key

3. Ask for Equibles by name

Confirm the connector is enabled, then ask for it by name: "using Equibles, ...".

Claude has its own web search, and left to choose it will often browse for a figure rather than call the connector. Naming Equibles gets you the processed, cited data, the filing and period behind every number, instead of whatever a search result says.

4. Test it

Open a new chat and ask any of these, and Claude should call an Equibles tool:

› Using Equibles, compare NVDA's latest earnings call with the previous quarter. Build a management accountability scorecard showing what was promised, delivered, missed, or is too early to judge; compare prior guidance with filed results; flag achievements that exceeded or were not foreshadowed by management's prior outlook; explain changes in tone and priorities; and cite every conclusion. Earnings

› Who are NVIDIA's top institutional holders this quarter? 13F

› Summarize Microsoft's most recent earnings call. Earnings

Troubleshooting

Connector not appearing?

Fully quit and reopen Claude Desktop after adding it — a reload isn't enough.

Claude answers without Equibles data?

It answered from memory or from its own web search. Confirm the connector is enabled, then re-ask starting with "using Equibles, ...". Naming the connector is the reliable way to keep Claude off web search and on the sourced data.

Access denied?

Re-approve the connector in Settings → Connectors, or if you're using a key, re-copy it from /dashboard/apikeys. If you're over your daily limit, see Rate limits.
