Installation

Deployed at https://mcp.steuerboard.com

{
  "command": "npx",
  "args": [
    "@steuerboard/mcp",
    "start",
    "--bearer-auth",
    ""
  ]
}

claude mcp add Steuerboard -- npx -y @steuerboard/mcp start --bearer-auth 

gemini mcp add Steuerboard -- npx -y @steuerboard/mcp start --bearer-auth 

{
  "command": "npx",
  "args": [
    "@steuerboard/mcp",
    "start",
    "--bearer-auth",
    ""
  ]
}

{
  "command": "npx",
  "args": [
    "@steuerboard/mcp",

npx @steuerboard/mcp --help

Progressive Discovery

MCP servers with many tools can bloat LLM context windows, leading to increased token usage and tool confusion. Dynamic mode solves this by exposing only a small set of meta-tools that let agents progressively discover and invoke tools on demand.

To enable dynamic mode, pass the --mode dynamic flag when starting your server:

{
  "mcpServers": {
    "Steuerboard": {
      "command": "npx",
      "args": ["@steuerboard/mcp", "start", "--mode", "dynamic"],
      // ... other server arguments
    }
  }
}

In dynamic mode, the server registers only the following meta-tools instead of every individual tool:

• list_tools: Lists all available tools with their names and descriptions.
• describe_tool_input: Returns the input schema for one or more tools by name.
• execute_tool: Executes a tool by name with its arguments.

This approach significantly reduces the number of tokens sent to the LLM on each request, which is especially useful for servers with a large number of tools.

Development

Run locally without a published npm package:

1. Clone this repository
2. Run npm install
3. Run npm run build
4. Run node ./bin/mcp-server.js start --bearer-auth ... To use this local version with Cursor, Claude or other MCP Clients, you'll need to add the following config:

{
  "mcpServers": {
    "Steuerboard": {
      "command": "node",
      "args": ["./bin/mcp-server.js", "start", "--bearer-auth", "..."]
    }
  }
}

Or to debug the MCP server locally, use the official MCP Inspector:

npx @modelcontextprotocol/inspector node ./bin/mcp-server.js start --bearer-auth ...

Cloudflare Deployment

To deploy to Cloudflare Workers:

npm install
npm run deploy

To run the cloudflare deployment locally:

npm install
npm run dev

The local development server will be available at http://localhost:8787

Then install with Claude Code CLI:

claude mcp add --transport sse Steuerboard http://localhost:8787/sse --header "authorization: ..."

Contributions

While we value contributions to this MCP Server, the code is generated programmatically. Any manual changes added to internal files will be overwritten on the next generation. We look forward to hearing your feedback. Feel free to open a PR or an issue with a proof of concept and we'll do our best to include it in a future release.
