Quick Start

Get Started in 4 Steps

Install HTTPeep

Download and install HTTPeep. The CLI tool (httpeep-cli / hp) is included out of the box — no separate install needed.

Install HTTPeep CLI Skills

Run the command below to register HTTPeep's AI Skills with your coding agent. Supports Claude Code, Codex CLI, Gemini CLI, and Cursor.

Terminal

npx skills add HTTPeep/agent-skills --skill httpeep-cli

Trust the Root Certificate

Launch the app and trust the root CA with one click, or run the CLI command below and enter your password.

Terminal

httpeep-cli cert install

Start Capturing & Debug with AI

Open your AI assistant and describe what you need. For example:

"Find all 5xx errors from the last 10 minutes and tell me why they're failing"

"Mock /api/user/profile to return a VIP user for testing"

"Create a rule to forward api.example.com to localhost:3000"

"Analyze the slowest requests and show me a breakdown"

How It Works

Three Steps to AI-Powered Debugging

Connect Your AI Assistant

Install HTTPeep CLI Skills with one command. Works with Claude Code, Codex CLI, Gemini CLI, and Cursor out of the box.

Describe What You Need

Type a natural language command like "Mock the /api/user response" or "Find all 5xx errors from the last hour".

AI Executes in Real-Time

Your assistant reads captured traffic, creates rules, analyzes sessions, and generates diagnostic reports — all through HTTPeep's CLI tools.

Mock /api/user response and change subscription.tier from free to pro, help me test edge cases

Analyzing: User needs to override subscription.tier in /api/user responses. I will search for recent matching sessions, inspect the response structure, then create a modify_response rule.

⚡Tool Callhttpeep_sessions_list

Arguments

{
  "url_like": "/api/user",
  "limit": 5,
  "status_code": 200
}

Result

Returned 3 matching sessions

CLI$ hp sessions list --url-like "/api/user" --limit 5

ID        METHOD  URL                      STATUS  DURATION
abc123    GET     /api/user                200     45ms
def456    GET     /api/user/profile        200     32ms
ghi789    POST    /api/user/update         200     120ms

Found 3 matching sessions. Inspecting the latest abc123 for response structure...

⚡Tool Callhttpeep_session_detail

Arguments

{
  "session_id": "abc123",
  "unredacted": true
}

CLI$ hp sessions list --id abc123 --format json

{
  "response_body_preview": {
    "id": "u_123",
    "name": "Alice",
    "subscription": {
      "tier": "free",
      "expires_at": "2026-12-31"
    }
  }
}

Response structure confirmed. Now creating a modify_response rule to override subscription.tier from "free" to "pro":

⚡Tool Callhttpeep_rules_upsert

Arguments

{
  "rule": {
    "id": "mock-user-tier-pro",
    "enabled": true,
    "match": {
      "domains": [{"type":"exact","value":"api.example.com"}],
      "paths": [{"type":"exact","value":"/api/user"}]
    },
    "actions": [{
      "type": "modify_response",
      "json_path": "$.subscription.tier",
      "replace_with": "pro"
    }]
  }
}

Result

Rule created, quota: { used: 2, limit: 10 }

CLI$ hp rules upsert --rule-file ./mock-tier-pro.json

✓ Rule "mock-user-tier-pro" upserted
  Quota: 2 / 10 used
  Builtin rules: 3

JSON Diffmodified

Before

{
  "id": "u_123",
  "name": "Alice",
  "subscription": {
    "tier": "free",
    "expires_at": "2026-12-31"

  "name": "Alice",
  "subscription": {
    "tier": "pro",
    "expires_at": "2026-12-31"
  }
}

✓ Mock rule active · matching requests return modified response

Frequently Asked Questions

What are HTTPeep AI Skills?

HTTPeep CLI Skills allow AI assistants to directly interact with your HTTP debugging session. Your AI agent can read captured traffic, create and manage rules, analyze errors, and generate reports — all from natural language commands via the CLI.

Which AI assistants are supported?

HTTPeep Skills work with any AI tool that supports CLI skills. This includes Claude Code, Codex CLI, Gemini CLI, Cursor, and more.

Do I need to install a plugin?

No plugin is needed. Run `npx skills add HTTPeep/agent-skills --skill httpeep-cli` to register the skill with your AI tool. That's it.

Is it free to use?

Yes. All CLI Skill capabilities are included in the free version of HTTPeep. No additional license or subscription is required.
