Reqable Traffic Capture

Reqable MCP Server exposes local Reqable capture traffic to MCP clients (Windsurf/Cursor/Claude/Codex).

Default architecture is local-only:

1. Reqable posts HAR(JSON) to http://127.0.0.1:18765/report.
2. Optional incremental WebSocket events can be posted to http://127.0.0.1:18765/ws/events.
3. reqable-mcp normalizes and stores requests/messages in local SQLite.
4. MCP tools query local data only (no cloud relay by default).

Features

• Local-first, privacy-first ingest path.
• Real-time ingest via Reqable Report Server.
• HAR file import fallback for missed sessions.
• HTTP request query/search/domain stats/API analysis.
• WebSocket session/message parsing for HAR entries carrying message-frame extensions.
• Cross-platform runtime (macOS / Linux / Windows with Python 3.10+).

Prerequisites

1. Install and open Reqable.
2. Configure Reqable Report Server to post to http://127.0.0.1:18765/report.
3. Ensure Node.js (for npx) and uv (for uvx) are available.

Installation

Run via npx (recommended)

npx -y reqable-mcp@latest

Local development

uv run reqable-mcp

MCP Client Configuration

{
  "mcpServers": {
    "reqable": {
      "command": "npx",
      "args": ["-y", "reqable-mcp@latest"]
    }
  }
}

Reqable Report Server Setup

Use these values in Reqable "Add Report Server":

1. Name: reqable-mcp-local
2. Match rule: * (or your target domains)
3. Server URL: http://127.0.0.1:18765/report
4. Compression: None (or keep consistent with your receiver)

After saving, generate traffic and call ingest_status to verify incoming payload count.

Important note: reqable-mcp still uses HTTP-only ingest transport (no native ws:// listener), but now supports two HTTP ingest paths: /report for HAR/session payload and /ws/events for incremental WebSocket events. WebSocket capture works when Reqable payload includes frame data (for example _webSocketMessages or event frame objects). Raw entry JSON and raw message JSON are preserved and exposed by WebSocket tools. HAR export/import remains the fallback when live pushes miss frames.

Available Tools

• ingest_status: ingest server state and counters
• import_har: import HAR from file path
• list_requests: list recent HTTP/WebSocket handshake requests with filters
• get_request: fetch request details by ID (full includes raw_entry)
• search_requests: keyword search in HTTP URL/body/raw uploaded entry (raw / raw_entry)
• list_websocket_sessions: list captured WebSocket sessions
• list_active_websocket_sessions: list recently active WebSocket sessions by latest captured frames
• get_websocket_session: fetch WebSocket session details and messages by ID (including raw_entry and message raw)
• tail_websocket_messages: incremental fetch by request_id + after_seq cursor
• search_websocket_messages: precise WebSocket message search by keyword, direction, type, opcode, close code, domain, and request ID
• analyze_websocket_session: summarize directions, message types, JSON shapes, and close events for a session
• export_websocket_session_raw: export the raw uploaded WebSocket entry and raw frame list
• health_report: ingest status + WebSocket data quality report
• repair_websocket_messages: backfill missing fields from raw frames (supports dry-run)
• get_domains: domain-level request statistics
• analyze_api: infer API shapes for a domain
• generate_code: generate sample client code from captured HTTP request

Privacy and Data Retention

• Data stays on local machine in default mode.
• Retention cleanup is applied to local DB records, including WebSocket messages.
• If ingest server is offline, Reqable failed report push is not retried.
