Agent-first MCP server for WeChat Mini Program debugging & automation via WeChat DevTools.

In-path gate · all MCP tools

Using io.github.Chaixueyuan/weapp-agent-mcp in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts—before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Limits of this verdict

- Semantic screen only - the deterministic conformance probe has not run on this server
- Confidence is reported but not yet calibrated (v1)
- Screen reads the tool description, not the live behavior
- advisory
- registry description only no input schema
- screen model 8b

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

Environment variables

WEAPP_WS_ENDPOINT

Automation WebSocket endpoint for the 'connect' flow (e.g. ws://localhost:9420). When a local endpoint is not listening and auto-launch is enabled, mp_ensureConnection may start DevTools if it can resolve a project.

WEAPP_AUTOMATOR_MODE

Force 'launch' or 'connect' mode. Defaults to 'launch' unless WEAPP_WS_ENDPOINT is set.

WEAPP_PROJECT_PATH

Optional Mini Program project directory used by launch and local auto-launch flows. The server can also resolve a persisted default, a recent project, or the current working directory.

WECHAT_DEVTOOLS_CLI_PATH

Optional override for the WeChat DevTools CLI binary path (e.g. /Applications/wechatwebdevtools.app/Contents/MacOS/cli on macOS).

WEAPP_DEVTOOLS_PORT

Automation websocket port passed to 'cli auto --auto-port' in launch mode (default 9420).

WEAPP_DEVTOOLS_TIMEOUT

Milliseconds passed to miniprogram-automator when launching WeChat DevTools.

WEAPP_AUTO_ACCOUNT

secret

Optional account passed to miniprogram-automator launch.

WEAPP_DEVTOOLS_TICKET

secret

Optional DevTools launch ticket.

WEAPP_TRUST_PROJECT

Whether launch mode should trust the project. Accepts true/false, 1/0, yes/no, or on/off.

WEAPP_DEVTOOLS_ARGS

Additional whitespace-separated CLI arguments passed during launch.

WEAPP_DEVTOOLS_CWD

Optional working directory passed to the DevTools launch process.

WEAPP_AUTOCLOSE

Whether to close or disconnect the automator session after each tool call. Accepts true/false, 1/0, yes/no, or on/off.

WEAPP_AUTOLAUNCH

Allow mp_ensureConnection to launch local WeChat DevTools with cli auto when the configured local automation port is not listening. Defaults to enabled; set false to disable.

WEAPP_LAUNCH_TIMEOUT

Milliseconds to wait for a locally auto-launched automation port (default 45000).

WEAPP_CONNECT_TIMEOUT

Milliseconds to wait for an automator websocket connection (default 45000).
