Wealthnow MCP server

Institutional financial data for AI agents: corporate bond prints and CDS spreads, a 10.6M-company private-markets graph, replayable options-chain history, 13F and insider flows, transcripts, and point-in-time fundamentals. 370+ REST endpoints across 22 data products, one sign-in.

Wealthnow is a hosted Model Context Protocol server. Add one URL to your AI app, sign in to Wealthnow, and your agent can call financial data tools directly.

Market data tools are read-only; nothing places orders or moves money.

• Default list: your agent first sees account_status and up to 12 starter tools.
• Full catalogue: connect to https://mcp.wealthnow.io/mcp?catalog=full to list every public tool. The same list is in the server card.
• Plans: your agent can call any tool your plan includes, whether or not it is listed. The Free plan covers market data, fundamentals and SEC filings.

Data and structured signals, not investment advice.

What your agent can reach

Most finance MCP servers stop at quotes and statements. Wealthnow exposes data that desks usually get through a terminal contract:

• Corporate credit: FINRA TRACE bond prints, 21.8M daily single-name CDS observations back to 2005, 15.8M credit-rating actions, and syndicated loans with pricing and covenants, keyed off the equity ticker.
• Private markets: 10.6M companies, 3M deals, 4.9M people, 645k investors and funds with IRR, DPI and TVPI, and 100k+ limited partners, with round-by-round syndicates, comparables and a valuation mark.
• Options chain history and tape: the entire chain with greeks, implied vol and open interest for every trading day captured since May 2026, replayable exactly as it stood, plus per-print options and futures trades and minute bars for about 10.5k tickers.
• Transcripts and events: 1.75M earnings-call transcript versions and 41.9M dated corporate events back to 1990.
• Institutional and insider flows: 13F holdings with quarter-over-quarter changes, a 308M-row mutual-fund holdings archive, Form 4, Rule 10b5-1 plans, Form 144 notices, insider buying clusters and congressional trades.
• Fundamentals done right: point-in-time vintages, as-reported XBRL, business segments and survivorship-bias-free prices, so backtests do not see the future.
• And more: options flow and gamma exposure, short interest and borrow cost, alternative data (WARN layoffs, supply-chain dependence, forensic accounting flags, lobbying, contracts, patents), news sentiment back to 2000, macro and rates, crypto, and a point-in-time ticker, CUSIP, ISIN and CIK crosswalk.

Try asking your agent:

• "Using Wealthnow, is the bond market more worried about Boeing than the stock market is?"
• "Using Wealthnow, who led each funding round for this startup, and what are its closest private peers?"
• "Using Wealthnow, what did NVDA's options chain look like the day before its last earnings?"

The Free plan (1,000 credits a month) covers prices, fundamentals and SEC filings. Credit, private markets and options history are on the Pro plan. Failed calls are never charged. Pricing · Get a free key

Connect

Claude (claude.ai, Claude Desktop, Claude mobile)

Add Wealthnow to Claude

To add it by hand instead:

1. In Claude, open Settings → Connectors → Add custom connector.
2. Enter the name Wealthnow and the URL https://mcp.wealthnow.io/mcp.
3. Click Connect, sign in to Wealthnow, then click Connect on the Wealthnow page.

A connector you add on the web also appears in Claude Desktop and on mobile.

Claude Code

claude mcp add --transport http wealthnow https://mcp.wealthnow.io/mcp

Then run /mcp inside Claude Code, choose wealthnow, and sign in.

Or install it as a plugin from this repository:

/plugin marketplace add Hlobo-dev/wealthnow-mcp/plugin install wealthnow@wealthnow

ChatGPT

1. Open ChatGPT on the web and go to Settings → Apps. Some accounts label this Apps & Connectors or Connectors.
2. Open Advanced settings and turn on Developer mode.
3. Back on Apps, click Create.
4. Enter the URL https://mcp.wealthnow.io/mcp and choose OAuth.
5. Sign in to Wealthnow when ChatGPT sends you there.

Cursor

Add Wealthnow to Cursor

Or add this to ~/.cursor/mcp.json:

{  "mcpServers": {    "wealthnow": { "url": "https://mcp.wealthnow.io/mcp" }  }}

The first time you use it, Cursor asks you to sign in to Wealthnow.

Codex

codex mcp add wealthnow --url https://mcp.wealthnow.io/mcpcodex mcp login wealthnow

codex mcp login opens the Wealthnow sign-in in your browser. To use an API key instead, set bearer_token_env_var = "WEALTHNOW_API_KEY" under [mcp_servers.wealthnow] in ~/.codex/config.toml.

Other MCP apps

In most apps that support remote MCP servers with OAuth, you add https://mcp.wealthnow.io/mcp as a remote (Streamable HTTP) server, and the app registers itself and runs the sign-in.

• Full sign-in tested end to end (sign in, back in the app, tools listed): Claude, ChatGPT, Grok, Cursor and Perplexity.
• Checked to reach the Wealthnow sign-in page (2026-09-28, 70 of 72 client variants): VS Code, Zed, GitHub Copilot CLI and the Copilot desktop app, Codex, Goose, Devin Desktop (formerly Windsurf), Warp, Continue, Cline, Raycast, the Code tab in Claude Desktop, Devin, Cline, Kiro, Amp, LM Studio, Postman, Slack and Figma. The steps after sign-in are the same as for the apps above.
• Gemini CLI 0.60 and later requires an iss parameter on the sign-in response; Wealthnow sends it. We have not yet run a Gemini CLI sign-in end to end.
• OpenCode cannot finish sign-in yet because of a bug in OpenCode (opencode#50510). Connect it with an API key (below).
• Devin Desktop (formerly Windsurf) and Warp refused the sign-in until 2026-09-28: their clients drop the iss parameter and report it missing (devin-cli#5). The server no longer asks clients to require it (it still sends it), so their sign-in is no longer refused for that reason. A key (below) also works.

If sign-in fails in your app, connect it with an API key instead:

Keep the key in your user-level settings, never in a project file that may be committed to a repository.

VS Code (.vscode/mcp.json): VS Code prompts for the key once and stores it securely.

{  "inputs": [    {      "type": "promptString",      "id": "wealthnow-key",      "description": "Wealthnow API key",      "password": true    }  ],  "servers": {    "wealthnow": {      "type": "http",      "url": "https://mcp.wealthnow.io/mcp",      "headers": { "X-API-Key": "${input:wealthnow-key}" }    }  }}

Gemini CLI (-s user saves it in ~/.gemini/settings.json; without it the key is written into the current project's .gemini/settings.json):

gemini mcp add -s user --transport http wealthnow https://mcp.wealthnow.io/mcp -H "X-API-Key: YOUR_WEALTHNOW_API_KEY"

Goose (~/.config/goose/config.yaml):

extensions:  wealthnow:    type: streamable_http    name: wealthnow    enabled: true    uri: https://mcp.wealthnow.io/mcp    headers:      X-API-Key: YOUR_WEALTHNOW_API_KEY    timeout: 300

OpenCode (your global config, ~/.config/opencode/opencode.json; the key comes from an environment variable):

{  "mcp": {    "wealthnow": {      "type": "remote",      "url": "https://mcp.wealthnow.io/mcp",      "headers": { "X-API-Key": "{env:WEALTHNOW_API_KEY}" },      "oauth": false    }  }}

Devin Desktop and Warp sign in on their own; a key also works, for example on a machine without a browser.

Devin Desktop (formerly Windsurf; ~/.config/devin/mcp_config.json on macOS and Linux, %APPDATA%\devin\mcp_config.json on Windows; the key comes from an environment variable):

{  "mcpServers": {    "wealthnow": {      "serverUrl": "https://mcp.wealthnow.io/mcp",      "headers": { "X-API-Key": "${env:WEALTHNOW_API_KEY}" }    }  }}

Warp (Settings → Agents → MCP servers, then add a server):

{  "wealthnow": {    "url": "https://mcp.wealthnow.io/mcp",    "headers": { "X-API-Key": "YOUR_WEALTHNOW_API_KEY" }  }}

VS Code and Zed sign in on their own; a key also works, for example on a machine without a browser.

Zed (your user settings, ~/.config/zed/settings.json): Zed skips sign-in when an Authorization header is set, and the server accepts the key as a bearer token.

{  "context_servers": {    "wealthnow": {      "url": "https://mcp.wealthnow.io/mcp",      "headers": { "Authorization": "Bearer YOUR_WEALTHNOW_API_KEY" }    }  }}

With an API key

Get a key from the Wealthnow dashboard and send it in the X-API-Key header. Keys start with wn_; keys created before October 2026 start with tengu_ and keep working. This works in any client that lets you set headers:

{  "mcpServers": {    "wealthnow": {      "url": "https://mcp.wealthnow.io/mcp",      "headers": { "X-API-Key": "YOUR_WEALTHNOW_API_KEY" }    }  }}

If your app only runs local servers, bridge to the remote one with mcp-remote:

{  "mcpServers": {    "wealthnow": {      "command": "npx",      "args": ["-y", "[email protected]", "https://mcp.wealthnow.io/mcp",               "--header", "X-API-Key:${WEALTHNOW_API_KEY}"],      "env": { "WEALTHNOW_API_KEY": "YOUR_WEALTHNOW_API_KEY" }    }  }}

Try it

Once connected, ask your agent:

Using Wealthnow, what's the latest quote for AAPL?

Or call it directly with an API key:

curl -s -X POST https://mcp.wealthnow.io/mcp \  -H 'Content-Type: application/json' \  -H 'Accept: application/json, text/event-stream' \  -H "X-API-Key: $WEALTHNOW_API_KEY" \  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call",       "params":{"name":"fundamentals_price_snapshot","arguments":{"ticker":"AAPL"}}}'

More in examples/: a quickstart, Python and TypeScript.
