Documentation

For more information on how to use and connect the MCP, visit the MCP docs.

Maintainers

The Perigon MCP Server is developed and maintained by the Perigon engineering team.

Lead Developer: Islem Maboud, responsible for the architecture, implementation, and ongoing development of this MCP server, including the remote transport layer, authentication handling, deployment configuration, and the MCP playground.

Usage

Playground

You can try out the Perigon MCP server in our playground.

Note: A valid Perigon API key is required to use the MCP. The MCP playground requires you to be already authenticated to the Perigon dashboard.

Connecting

You can connect to our remote MCP server using any MCP-compatible client.

Server URL: https://mcp.perigon.io

The recommended transport is Streamable HTTP (/v1/mcp). SSE (/v1/sse) is supported for legacy clients but not recommended for new integrations.

Quick Setup Examples

Streamable HTTP — native support (recommended):

{
  "mcpServers": {
    "perigon_news_api": {
      "url": "https://mcp.perigon.io/v1/mcp",
      "type": "http",
      "headers": {
        "Authorization": "Bearer YOUR_PERIGON_API_KEY"
      }
    }
  }
}

Streamable HTTP — via mcp-remote (for clients without native HTTP support):

{
  "mcpServers": {
    "perigon_news_api": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote@latest",
        "https://mcp.perigon.io/v1/mcp",
        "--header",
        "Authorization: Bearer ${PERIGON_API_KEY}"
      ],
      "env": {
        "PERIGON_API_KEY": "YOUR_PERIGON_API_KEY"
      }
    }
  }
}

For Claude Code (CLI):

claude mcp add --transport http perigon_news_api https://mcp.perigon.io/v1/mcp \
  --header "Authorization: Bearer YOUR_PERIGON_API_KEY"

SSE (legacy clients only):

{
  "mcpServers": {
    "perigon_news_api": {
      "url": "https://mcp.perigon.io/v1/sse",
      "type": "sse",
      "headers": {
        "Authorization": "Bearer YOUR_PERIGON_API_KEY"
      }
    }
  }
}

📖 For detailed setup instructions for different clients, see our comprehensive MCP documentation.

Selecting specific tools

By default all tools permitted by your API key are available. You can restrict a session to a smaller set by appending a ?tools= query parameter to the server URL. This is useful for reducing context size and keeping the model focused.

https://mcp.perigon.io/v1/mcp?tools=search_news_articles,search_news_stories

• Pass a comma-separated list of tool names, or all to explicitly activate every permitted tool.
• Only tools your API key already has access to will be activated — the parameter cannot expand permissions.
• Omitting the parameter, passing an empty value, or passing all are all equivalent and activate every permitted tool.

Example — Cursor config scoped to article and story search:

{
  "mcpServers": {
    "perigon_news_api": {
      "url": "https://mcp.perigon.io/v1/mcp?tools=search_news_articles,search_news_stories",
      "type": "http",
      "headers": {
        "Authorization": "Bearer YOUR_PERIGON_API_KEY"
      }
    }
  }
}

Prompt Examples

When prompting your agent we recommend providing the current date (or a tool to get it) unless the agent already has access to such information, this is because some models like Claude will otherwise think the current date is their knowledge cutoff and they will retrieve outdated information frequently.

News Articles & Stories:

• Give me the top 5 political headlines in the United States from today.
• What business stories are trending in New York today?
• Show me the latest tech news from California this week.
• Find political news from swing states in the last 3 days.
• Show me cryptocurrency-related stories from the past week.

Journalists & Sources:

• Find local news sources in Texas.
• Who are the top business journalists at major publications?
• Find journalists covering renewable energy, then show me their recent articles.
• Which journalists write the most about climate policy?

Supported tools

The full list of available tools — including names, descriptions, and parameter schemas — is visible in the MCP playground. The tools available to you depend on the scopes granted to your API key.
