mcp-compressor Python SDK
Python SDK and CLI wrapper for mcp-compressor.
The public Python import is mcp_compressor:
from mcp_compressor import CompressorClient
Quick start
The primary SDK object is CompressorClient. It starts a local session and returns a CompressorProxy; no mcp-compressor stdio subprocess is required.
from mcp_compressor import CompressorClient
servers = {
"alpha": {
"command": "python",
"args": ["alpha_server.py"],
},
"atlassian": {
"url": "https://mcp.atlassian.com/v1/mcp",
},
}
with CompressorClient(
servers=servers,
mode="compressed",
compression_level="medium",
include_tools=["getConfluencePage", "updateConfluencePage"],
toonify=True,
) as proxy:
print([tool.name for tool in proxy.tools])
result = proxy.invoke(
"getAccessibleAtlassianResources",
{},
server="atlassian",
)
print(result)
Modes
CompressorClient accepts these modes:
compressed— expose compressed wrapper tools such as<server>_get_tool_schemaand<server>_invoke_tool.cli— expose CLI/help tools for generated shell command usage.bash— expose Just Bash command integration for command-oriented agents.
Generated Python and TypeScript clients are produced with proxy.write_client(...) rather than by selecting a long-lived session mode.
Just Bash metadata
Just Bash mode lets language hosts register backend MCP tools as shell-style commands:
from mcp_compressor import CompressorClient, create_just_bash_commands
with CompressorClient(servers=servers, mode="bash") as proxy:
commands = {cmd.command_name: cmd for cmd in create_just_bash_commands(proxy)}
print(commands["atlassian_get-accessible-atlassian-resources"]([]))
Duplicate backend command names are prefixed with the provider name, for example alpha_echo and beta_echo.
Generated clients
A connected proxy can write shell, Python, or TypeScript clients that call the live proxy:
with CompressorClient(servers=servers, compression_level="max") as proxy:
proxy.write_client("cli", "./bin", name="atlassian")
proxy.write_client("python", "./generated-py", name="atlassian")
proxy.write_client("typescript", "./generated-ts", name="atlassian")
Packaging smoke test
Build a local wheel and verify it imports from a clean virtualenv:
uvx maturin build --release --out dist
python -m venv /tmp/mcp-compressor-wheel-test
/tmp/mcp-compressor-wheel-test/bin/python -m pip install "$PWD"/dist/*.whl
cd /tmp
/tmp/mcp-compressor-wheel-test/bin/python -c "from mcp_compressor import CompressorClient, ToolSpec"
CI runs the same kind of wheel smoke test before uploading the built wheel as an artifact.
Advanced helpers
Low-level helpers such as compress_tool_listing, parse_tool_argv, and ToolSpec remain available for tests and advanced integrations, but the primary SDK entry point is CompressorClient.
