Claude Local Server Connection

See Claude Desktop MCP docs for more info.

Install uv (a modern Python package and project manager):

curl -LsSf https://astral.sh/uv/install.sh | sh

Open Claude Desktop developer settings and edit your claude_desktop_config.json file to add the following configuration:

{
  "mcpServers": {
    "alphavantage": {
      "command": "uvx",
      "args": ["marketdata-mcp-server", "YOUR_API_KEY"]
    }
  }
}

Replace YOUR_API_KEY with your actual Alpha Vantage API key.

Requirements:

• ChatGPT Plus account (or higher tier)
• Developer mode enabled (beta feature) - see OpenAI's Developer Mode documentation

📺 Watch the setup tutorial - Click the image below to watch a step-by-step video guide:

📺 Already have your Alpha Vantage MCP server set up? Below are a few examples of ChatGPT performing various stock analysis & charting tasks:

Setup (Recommended, OAuth):

1. Go to ChatGPT Settings → Apps
2. Click on Advanced settings → enable Developer mode
3. Return to the Apps submenu, then click Create app.
4. MCP Server URL: https://mcp.alphavantage.co/mcp
5. Authentication: OAuth. When you connect, a consent page opens where you enter and authorize your Alpha Vantage API key.

Legacy (API key in URL, deprecated):

1. Go to ChatGPT Settings → Apps
2. Click on Advanced settings → enable Developer mode
3. Return to the Apps submenu, then click Create app.
4. MCP Server URL: https://mcp.alphavantage.co/mcp?apikey=YOUR_API_KEY (replace YOUR_API_KEY with your actual Alpha Vantage API key).
5. Authentication: No authentication

Note: When you return to your conversation, your UI will clearly indicate that you are in Developer mode. ChatGPT will retain memory of any previous remarks made within the same chat session; however, these sessions may not be persisted, meaning the conversation generated while Developer mode is active may not be saved or accessible once closed.

Troubleshooting for ChatGPT Plus Accounts

While Developer mode is available for both Plus and Pro accounts, on Plus accounts, first-time MCP tool execution may exhibit inconsistent behavior. This primarily affects large data payloads returned from the MCP server. If you notice that MCP calls abruptly terminate without returning any JSON response, try the following:

1. Confirm Connection

   • Confirm the connection by prompting:
     Code

     Copy

     List 3 functions available in Alpha Vantage MCP server.
     

   • You should see endpoints like TIME_SERIES_DAILY and TIME_SERIES_INTRADAY.

2. Force JSON Passthrough with simple payload

   • Use the following prompts in sequence to prime ChatGPT to surface the full payload:
     Code

     Copy

     Run ADD_TWO_NUMBERS from Alpha Vantage MCP Server using 3 and 6, and then show the JSON response.
     

   • If successful, ChatGPT should ask you to Confirm or Deny the call. Click Confirm.
   • If it doesn't, use the 🔄 "Try Again..." button and see if you get the Confirm/Deny prompt.
   • If this doesn't work, ask ChatGPT the following, and if it starts Thinking make it Skip, so that it doesn't try the call again and instead outputs its conversational response.
     Code

     Copy

     Why aren't you receiving a JSON response?
     

   • Then, regardless of the response, prompt ChatGPT
     Code

     Copy

     Explicitly request a return value from the tool response to verify what the server outputs.
     

   • Typically, this gets ChatGPT to ask you to Confirm or Deny the call. Click Confirm.
   • Sometimes, ChatGPT will insist it has no active connection to Alpha Vantage MCP Server. Just tell it to "try again".
   • If payloads still fail to appear, start a New Chat and try Step #2 again.

3. Force JSON Passthrough with large payload

   • Once step #2 has been successful, repeat step #2 with the larger call:
     Code

     Copy

     Run TIME_SERIES_DAILY using NVDA, and then show the JSON response.
     

   • Use the fallback steps from Step #2 if ChatGPT does not ask you to Confirm or Deny the call.
   • Once you observe ChatGPT successfully return part of the raw JSON payload from the larger call, you can typically continue on with more conversational queries.

Requirements:

• SuperGrok (or higher tier)

Setup:

1. Click the + button → Connectors → Add connector → Custom
2. Name: Alpha Vantage MCP Server (or whatever you prefer)
3. Server URL: https://mcp.alphavantage.co/mcp?apikey=YOUR_API_KEY (replace YOUR_API_KEY with your actual Alpha Vantage API key).
4. Click Add Connector

Requirements:

• Azure subscription with access to Azure AI Foundry

📺 Watch the setup tutorial. (Click image below.)

Microsoft Azure AI Foundry — Agent Service Connection

To connect a Foundry agent to this MCP server:

1. Open your agent (or Create Agent from Home Dashboard) in Azure AI Foundry's Agent playground or Agent designer.
2. In the Tools section of the agent configuration, click Add → Browse All Tools. Select the Catalog tab, then search for Alpha Vantage MCP Server or filter by Finance under the Category filter. Click Create.
3. Configure the connection with the following settings:
   • Name: Accept the default generated name, or enter your own
   • (read-only) Remote MCP Server endpoint: https://mcp.alphavantage.co/mcp
   • (read-only) Authentication: Key-based
   • Credential — apikey: Enter your Alpha Vantage API key
4. Click Connect.

Recommended Agent Instructions:

Add the following to your agent's system prompt to optimize performance:

You are a helpful financial agent with access to market data through Alpha Vantage MCP Server.
The Alpha Vantage functions (TIME_SERIES_DAILY, RSI, COMPANY_OVERVIEW, etc.) are exposed
directly as MCP tools. Call them by name with their parameters, e.g.
TIME_SERIES_DAILY(symbol="IBM", outputsize="compact").
Always use Alpha Vantage MCP Server for market data queries. Do not answer from prior knowledge or web search.

Requirements:

• Hermes Agent installed with the hermes CLI available

Hermes Remote Server Connection (Recommended, OAuth)

Add the server and start the authorization flow:

hermes mcp add alphavantage --url https://mcp.alphavantage.co/mcp --auth oauth
hermes mcp login alphavantage

Or configure it directly in config.yaml:

mcp_servers:
  alphavantage:
    url: https://mcp.alphavantage.co/mcp
    auth: oauth

A browser consent page opens where you enter and authorize your Alpha Vantage API key. If you would like to update/rotate the API key in the future, run hermes mcp login alphavantage (or hermes mcp reauth alphavantage) again and enter the new key on the consent page.

Verify the connection with:

hermes mcp test alphavantage

Hermes Remote Server Connection (API key in URL)

For non-interactive environments (e.g., terminal-only setups where the browser-based OAuth flow is not possible), put the API key in the server URL instead. Add the server to your config.yaml under mcp_servers:

mcp_servers:
  alphavantage:
    url: https://mcp.alphavantage.co/mcp?apikey=YOUR_API_KEY

Replace YOUR_API_KEY with your actual Alpha Vantage API key. To update/rotate the API key, simply change the key in the URL.

Verify the connection with:

hermes mcp test alphavantage

Requirements:

• Mac with Apple Silicon (or dedicated Mac mini)
• LLM API Key (OpenAI used in demo)
