Quick Install

One command in Claude Code:

/plugin marketplace add reatlat/fullstory-claude-plugin
/plugin install fullstory-reatlat@fullstory-marketplace

Also works in Cursor (Marketplace panel, same URL) and VS Code Copilot (Chat: Install Plugin from Source).

No local server. No API keys to juggle. OAuth handles auth — you sign in once and it just works.

Hermes Agent

Hermes loads skills natively and has built-in MCP support — no plugin system needed.

# Clone the repo
git clone https://github.com/reatlat/fullstory-claude-plugin ~/fullstory-claude-plugin

# Symlink skills into Hermes
ln -s ~/fullstory-claude-plugin/skills/* ~/.hermes/skills/

Add the MCP server to ~/.hermes/config.yaml:

mcp_servers:
  fullstory:
    url: "https://api.fullstory.com/mcp/fullstory"

Restart Hermes. All 46 skills load automatically, and MCP tools appear as mcp_fullstory_*. OAuth flow triggers on first tool call.

Claude Desktop (manual setup)

Claude Desktop doesn't support the plugin marketplace — you get the MCP tools but not the skills/agents. Add this to claude_desktop_config.json:

{
  "mcpServers": {
    "fullstory": {
      "type": "http",
      "url": "https://api.fullstory.com/mcp/fullstory"
    }
  }
}

Config file locations: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS), %APPDATA%\Claude\claude_desktop_config.json (Windows). Restart Claude Desktop after editing.

What It Does

Fullstory records every session on your site. This plugin lets Claude read that data.

Before: Export CSV → pivot table → screenshot → Slack → someone asks "but why?" → repeat.

After: Type a question. Get an answer.

You ask	Claude does
"What's the top frustration on our product right now?"	Builds a rage-click metric across all pages, surfaces the worst offenders, pulls sessions to show you exactly what users are clicking
"How many users abandoned checkout last month, by device?"	Resolves or builds a funnel metric, attaches segment, computes, returns a table with percentages
"Show me sessions where enterprise users hit errors on settings"	Builds enterprise segment, finds error sessions, reads each transcript in isolation, synthesizes patterns
"Is our new onboarding flow actually reducing drop-off?"	Trend metric comparing before/after deploy date, with statistical context
"Find session #abc123 and tell me why the submit button didn't work"	Opens session, steps through key moments, diffs before/after the click, reports what broke

It doesn't just answer "how many." It answers "why" — by reading the actual sessions behind the numbers.
