Tools

ragbrain_register

Inputs:

  • email

  • password

  • full_name optional

ragbrain_login

Inputs:

  • email

Streamable HTTP client config example

{
  "mcpServers": {
    "ragbrain-auth": {
      "url": "http://127.0.0.1:8765/mcp"
    }
  }
}

Start the server first:

cd /home/mediax/research/mcp_research
.venv/bin/python ragbrain_auth_mcp_server.py

Note: some clients only support local STDIO MCP servers. Use a client that supports MCP Streamable HTTP.

OpenAI Agents SDK client

This repo also includes a simple OpenAI Agents SDK agent that uses the MCP server above.

Start the MCP server:

cd /home/mediax/research/mcp_research
.venv/bin/python ragbrain_auth_mcp_server.py

In another terminal, verify the agent can see the MCP tools without calling OpenAI:

cd /home/mediax/research/mcp_research
.venv/bin/python ragbrain_auth_agent.py --list-tools

Run the agent with OpenAI:

cd /home/mediax/research/mcp_research
export OPENAI_API_KEY="..."
.venv/bin/python ragbrain_auth_agent.py "Login to RagBrain with email user@example.com and password ..."

Optional config:

export RAGBRAIN_MCP_URL="http://127.0.0.1:8765/mcp"
export OPENAI_AGENT_MODEL="gpt-5.6"

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
