code-analysis-client 1.6.39

Async JSON-RPC client for the code-analysis MCP server (mcp-proxy-adapter JsonRpcClient)

code-analysis-client

Async Python client for the code-analysis server. It wraps mcp-proxy-adapter’s JsonRpcClient, so you get the adapter’s built-in methods (queue, transfer, help, health, …) plus thin helpers to run any registered server command.

Install

pip install code-analysis-client

Usage

import asyncio
from code_analysis_client import CodeAnalysisAsyncClient


async def main() -> None:
    client = CodeAnalysisAsyncClient(
        protocol="https",
        host="127.0.0.1",
        port=15001,
        cert="/path/client.crt",
        key="/path/client.key",
        ca="/path/ca.crt",
        timeout=120.0,
    )
    async with client:
        h = await client.rpc.help()
        r = await client.call("list_projects", {"include_deleted": False})
    print(h, r)


asyncio.run(main())

Build client settings from the same JSON shape as the pipeline adapter settings (host, port, protocol, optional ssl with cert / key / ca or *_path aliases), or from a full server config.json object.

from code_analysis_client import CodeAnalysisAsyncClient

client = CodeAnalysisAsyncClient.from_server_config(config_dict, timeout=60.0)

Queued/long commands: use client.call_unified(..., expect_queue=True, auto_poll=True) or the underlying client.rpc.execute_command_unified(...).

Validation using the server schema

The authoritative input schema is whatever the running server returns from help with cmdname set to the command. The client calls that, optionally caches the result, performs the same shallow checks as the server’s BaseMCPCommand (types, required, enum, additionalProperties), then runs the command.

async with CodeAnalysisAsyncClient(host="127.0.0.1", port=15001) as client:
    # Explicit
    out = await client.call_validated(
        "list_projects",
        {"include_deleted": False},
    )
    # Dynamic wrapper: same as call_validated("list_projects", {...})
    out = await client.commands.list_projects(include_deleted=False)
    # After server reload
    client.clear_command_schema_cache()

Use call_unified_validated when you need queue polling. Pass refresh_schema=True on a single call to bypass the in-memory schema cache.

High-level facades (aligned with live server registry)

The client does not wrap CST commands (cst_load_file, …) or legacy file I/O (universal_file_read, read_project_text_file, …). Those commands are removed from the server registry. Use the facades below or generic call / commands.*.

Facade	Property	Server commands
Client DB sessions + transfer	client.file_sessions	session_*, subordinate_session_*, project_file_transfer_*, project_file_advisory_lock_batch
Universal edit sessions	client.universal_files	universal_file_open, edit, write, close, preview
Any registered command	client.call / client.commands.<name>	schema from live help()

Canonical command lists: code_analysis_client.server_api — exported as FILE_SESSION_COMMANDS, FILE_SESSION_FACADE_METHODS, CLIENT_FACADE_COMMANDS, REMOVED_COMMANDS.

Sync checks (in-process registry):

pytest tests/test_client_server_api_sync.py tests/test_code_analysis_client.py -k session

Package version is in the root pyproject.toml; before a client wheel build run python scripts/sync_code_analysis_client_version.py (also done by release_build.sh).

Examples (this repository)

Runnable scripts live under client/examples/. Long-form “man page” style documentation is embedded in the module docstrings of those Python files (see client/examples/README.md for how to read them).

Script	Purpose
run_all_examples.py	Full API tour + runs all live sibling scripts
ex_minimal_validated.py	Smallest validated RPC example
ex_universal_files.py	All UniversalFileClient methods (open/edit/write/close/preview)
ex_session_view_subordinates.py	session_view and subordinate CRUD
ex_file_sessions.py	Sessions, locks, transfer roundtrip
ex_config_only.py	Parse config.json without TCP

casmgr --config config.json start
python client/examples/run_all_examples.py

Development

From the repository root:

pip install -e ./client
pytest tests/test_code_analysis_client.py

Releasing to PyPI (version = root code-analysis project)

The client wheel version is read from client/code_analysis_client/version.txt. That file must match [project].version in the repository root pyproject.toml. Sync before build:

python scripts/sync_code_analysis_client_version.py
cd client && python -m build && twine check dist/* && twine upload dist/*
