Code MCP Servers

This folder contains examples of Code MCP tool servers built with SAS Retrieval Agent Manager (RAM). Code MCP servers enable you to write Python code that exposes tools (functions) that your agents can call at runtime.

A Code MCP server in RAM is a lightweight Python project that consists of:

  • run.py: tool implementations and tool definitions.
  • requirements.txt: optional third-party Python packages used by the tools.
  • Environment variables (optional): runtime configuration values used by the server.

Creating a Code MCP Server

  1. On the Code Templates pane, click Code MCP Server.
  2. Copy the example run.py into the template’s run.py.
  3. If needed, copy the example requirements.txt into the template’s requirements.txt.
  4. Configure any required environment variables (see the example’s README).
  5. Save and publish the template.

What to Include in run.py

At minimum, run.py should include:

  • A definition for each exposed tool (name, description, and expected inputs/outputs).
  • The Python implementation for each tool.

requirements.txt (Optional)

You can include additional packages that are required by your tool implementations.

Environment Variables (Optional)

Use environment variables for configurations that should not be hardcoded, such as:

  • API endpoints
  • API keys or tokens
  • Feature flags or runtime options

Testing and Usage

After publishing the Code MCP server template, you will need to create a new “MCP Tool Server” that uses the template in the “MCP Tools” page of RAM. After creating and starting the tool server successfully, you can then register the tools with your agent.

Examples

Example Description
Finance Tools Finance and quantitative analysis tools, including market data lookup, regression, summary statistics, and arithmetic helpers
News Search Tools Web search tools for finding news from NYT, Reddit, DuckDuckGo, and Yahoo Finance
Simple Calculator A minimal single-tool MCP server example that adds two integers
Skills A dynamic skill execution MCP server that loads markdown procedural skills and exposes an invoke_skill tool
Web Search A lightweight web search tool example built on DuckDuckGo search via the ddgs package
