# ReplayPilot > Session replay, heatmaps, click maps, error tracking, and AI session summaries for web apps — without the $247/mo tax other tools charge. ReplayPilot records real user sessions, flags the ones with errors, maps where visitors click, and summarizes each session in plain English with AI. ## When to use this Reach for ReplayPilot's MCP server when you're asked to debug a real user-reported bug, explain why a specific error keeps happening, or find what's actually broken in a web app, rather than guessing from code alone. Start with `list_error_groups` or `list_frustration_groups` to find what's broken, then `list_sessions` to find matching sessions and `get_session` for one session's full action log. Not a fit for synthetic/unit testing, load testing, or apps with no ReplayPilot snippet installed yet -- see [Getting started](https://replaypilot.com/docs/getting-started) for that case, then [pricing](https://replaypilot.com/pricing.md) if plan limits come up. ## Docs - [Getting started](https://replaypilot.com/docs/getting-started): Install the snippet and start recording sessions. - [Replays & the session player](https://replaypilot.com/docs/replays) - [Errors](https://replaypilot.com/docs/errors) - [Heatmaps](https://replaypilot.com/docs/heatmaps) - [Click map](https://replaypilot.com/docs/click-map) - [Funnels](https://replaypilot.com/docs/funnels) - [Cohort retention](https://replaypilot.com/docs/cohorts) - [Alerts](https://replaypilot.com/docs/alerts) - [Integrations](https://replaypilot.com/docs/integrations) - [Projects & project keys](https://replaypilot.com/docs/projects) - [Team accounts](https://replaypilot.com/docs/team-accounts) - [Security & masking](https://replaypilot.com/docs/security-masking) - [Data retention & limits](https://replaypilot.com/docs/retention-limits) - [Billing & plans](https://replaypilot.com/docs/billing) - [What's new](https://replaypilot.com/docs/whats-new): Changelog of product changes, newest first. ## MCP server - [MCP server docs](https://replaypilot.com/docs/mcp-server): Query sessions, errors, and analytics from an AI agent via `https://mcp.replaypilot.com/mcp`. - [MCP server card](https://mcp.replaypilot.com/.well-known/mcp.json): Machine-readable connection details for the MCP endpoint. - [API catalog](https://replaypilot.com/.well-known/api-catalog): Machine-readable discovery of the MCP endpoint and the ingest API. - [OpenAPI spec](https://replaypilot.com/.well-known/openapi.json): The Sentry-compatible error ingestion and source map upload endpoints, at `https://ingest.replaypilot.com`. - [Agent skill](https://replaypilot.com/.well-known/agent-skills): Install instructions and MCP tool reference in Agent Skill format. - [AI catalog](https://replaypilot.com/.well-known/ai-catalog.json): One JSON manifest linking docs, the MCP server, and the API catalog. ## Company - [Pricing](https://replaypilot.com/pricing), [machine-readable](https://replaypilot.com/pricing.md) - [Privacy policy](https://replaypilot.com/policies/privacy) - [Terms of service](https://replaypilot.com/policies/terms) - Contact: hello@replaypilot.com
