Fullstory MCP

What does a Fullstory MCP server do?

The Fullstory MCP server lets an AI assistant query your behavioral data. It builds and runs metrics, segments, funnels and journeys, pulls sessions and reads their event transcripts. Agentic session review captures screenshots at a timestamp, so the assistant can see what a user saw. Your privacy rules still apply, including masking and exclusions.

• Fullstory for Customer Agents: a separate read-only server at https://api.fullstory.com/mcp/activations gives support and sales agents context on one session. Fullstory points aggregate analytics to the main server.
• Skills: the fullstory-skills plugin adds skills and a session-context agent on top of the same tools.

Is there an official Fullstory MCP server?

Yes. Fullstory publishes the server and its docs, and its release notes show a beta in April 2026 and general availability in October 2026. Claude's directory lists the connector as made by Fullstory. Fullstory also maintains the fullstory-skills plugin on its own GitHub org.

• Fullstory's FAQ still says "during Early Access" where it explains manual saving. The October release notes are the later statement.

What is the Fullstory MCP server URL, and how do you sign in?

The URL is https://api.fullstory.com/mcp/fullstory. You sign in with OAuth in a browser as yourself. An API key suits gateways and shared services, sent as a Bearer token, and Fullstory recommends a Standard key. Some clients need the regional URL: https://api.eu1.fullstory.com/mcp/fullstory for EU orgs or https://api.na1.fullstory.com/mcp/fullstory for US orgs.

• StoryAI and the Model Context Protocol toggle must both be on, under Settings > StoryAI Features. If StoryAI is opted out, the client shows as connected with no tools.
• Fullstory says all orgs have MCP on by default.
• Each connection covers one org, so several orgs need several connections.

What can a Fullstory MCP server read and change?

Most tools read. The build_ tools turn a description into a segment, metric, funnel or journey. Fullstory's tools reference says segments, funnels and journeys persist, while its limits page says the server only creates drafts that need a manual save. Check your org after a build. Users, billing and settings stay out of reach.

What it can read

• Metrics and segments: compute_metric, get_metric, get_segment and get_view_counts.
• Funnels and journeys: compute_funnel, get_funnel_sessions, compute_journey and get_journey_sessions.
• Sessions: get_sessions, get_session_events and get_pages.
• Session review: review-open, review-snapshot, review-zoom, review-summary and review-close.
• Frustration signals: discover_groups and get_opportunity_stats. get_opportunities and the other lookup tools need the StoryAI Premium SKU.

What it can change

• Segments: build_segment persists a segment and returns its segment_id. update_segment refines one.
• Funnels and journeys: build_funnel and build_journey persist a definition. The update_ tools produce a refined copy and leave the source unchanged.
• Metrics: build_metric and update_metric create definitions. Fullstory's FAQ says unsaved segments and metrics are discarded when the session ends.

How do you set up a Fullstory MCP server in Claude, ChatGPT and Cursor?

Fullstory documents all three as listed installs. Claude uses the connector directory, ChatGPT and Codex use the plugin directory, and Cursor uses the plugin marketplace. Each route signs in with OAuth. Check that StoryAI is on first, because the client connects with no tools if it's off.

What can you ask a Fullstory MCP server?

Good first prompts name a page, a date range and a comparison. These examples follow Fullstory's release impact workflow and use tools it documents. Keep session pulls small, since session tools stop at 50. Prompts that build a segment, metric or funnel can create objects, so check what the assistant made.

What are the limits of a Fullstory MCP server?

Fullstory limits the server to 3 requests a second, with a burst of 20, per org and per endpoint. Session tools default to 10 and stop at 50. Group-by results stop at 50 rows, so Fullstory says it doesn't suit bulk exports. It covers part of the product, focused on metrics, segments and session replay.

• Each server connects to one org, and cross-org queries aren't supported.
• Fullstory doesn't schedule queries. Scheduling depends on your AI client, and rate limits still apply.
• MCP rate limits are tracked separately from Server API limits.

How much does a Fullstory MCP server cost?

Fullstory lists no separate price for the server, and it's available to all paying customers. Fullstory shows no public prices for Business, Advanced or Enterprise, so you request a quote. FullstoryFree costs nothing but leaves out StoryAI, which the server needs. Four lookup tools also need the StoryAI Premium SKU.

• FullstoryFree includes 30,000 sessions a month, 12 months of retention and up to 10 users.
• Fullstory for Customer Agents is part of Anywhere: Activation, with 1,000 Activations a month on Enterprise and Advanced plans. Each tool call uses Activations.

What are the alternatives to a Fullstory MCP server?

The main alternatives are another behavior tool's server or a product analytics server. Product analytics MCP servers compared covers Amplitude, Mixpanel, PostHog, Pendo and Contentsquare side by side, so you can match the server to the tool that holds your trusted numbers. Each option below is a separate product.

• Microsoft Clarity MCP: Site behavior metrics, if you run Clarity beside or instead of Fullstory.
• Pendo MCP: Usage, guides and feedback, if Pendo holds your product data.
• Amplitude MCP: The route if Amplitude holds your product analytics.
• PostHog MCP: The route if PostHog holds your product analytics.

Which skill goes with a Fullstory MCP server?

Use the free Agent write safety skill before you let an assistant build segments, funnels or journeys, because those can land in your Fullstory org. Use the Analytics tool selector to decide whether Fullstory or a product analytics tool should answer a question, so you connect the server that holds the right data.

• Agent write safety: Sets approvals before an agent can create objects in your org.
• Analytics tool selector: Helps you choose which analytics tool should answer each question.
