Strands Agents | CleanTextLab Docs

Requirements

Python 3.10+
CleanTextLab Pro API key
Strands Agents installed

python -m venv .venv
source .venv/bin/activate
pip install strands-agents

Option A: Local MCP via npx (recommended for local dev)

from strands import Agent
from strands.tools.mcp import MCPClient
from mcp import stdio_client, StdioServerParameters

cleantextlab = MCPClient(
    lambda: stdio_client(
        StdioServerParameters(
            command="npx",
            args=["-y", "cleantextlab-mcp"],
            env={"CLEANTEXTLAB_API_KEY": "ctl_live_YOUR_KEY"},
        )
    )
)

with cleantextlab:
    agent = Agent(tools=cleantextlab.list_tools_sync())
    agent("Remove line breaks from: Hello\\nworld")

Option B: Hosted MCP (SSE)

from strands import Agent
from strands.tools.mcp import MCPClient
from mcp import sse_client, SSEServerParameters

cleantextlab = MCPClient(
    lambda: sse_client(
        SSEServerParameters(
            url="https://cleantextlab.com/api/mcp/sse",
            headers={"x-api-key": "ctl_live_YOUR_KEY"},
        )
    )
)

with cleantextlab:
    agent = Agent(tools=cleantextlab.list_tools_sync())
    agent("Generate an ASCII tree from: src/app/page.tsx")

Why MCP for agents?

Deterministic output for formatting tasks
Lower token usage by offloading heavy text operations
Reusable tools across agent workflows
