mcp.run Setup

You will need to get an mcp.run session ID by running:

npx --yes -p @dylibso/mcpx gen-session --write

This will generate a new session and write the session ID to a configuration file that can be used by mcp-run.

If you need to store the session ID in an environment variable you can run gen-session without the --write flag:

npx --yes -p @dylibso/mcpx gen-session

which should output something like:

Login successful!
Session: kabA7w6qH58H7kKOQ5su4v3bX_CeFn4k.Y4l/s/9dQwkjv9r8t/xZFjsn2fkLzf+tkve89P1vKhQ

Then set the MPC_RUN_SESSION_ID environment variable:

$ export MCP_RUN_SESSION_ID=kabA7w6qH58H7kKOQ5su4v3bX_CeFn4k.Y4l/s/9dQwkjv9r8t/xZFjsn2fkLzf+tkve89P1vKhQ

from mcp_run import Client  # Import the mcp.run client

client = Client()  # Create the client, this will check the
# default location for the mcp.run config or
# the `MCP_RUN_SESSION_ID` env var can be used
# to specify a valid mcp.run session id

# Call a tool with the given input
results = client.call_tool("eval-js", params={"code": "'Hello, world!'"})

# Iterate over the results
for content in results.content:
    print(content.text)
