Fictura MCP server

Fictura is the growth platform for Expo and React Native apps: paywalls and onboarding flows built in the Studio editor, subscription analytics and funnels, A/B experiments, attribution and ad spend, deep links, App Store and Google Play analytics, and error tracking with stack traces. This server puts all of it in reach of Claude, ChatGPT, Codex, Cursor, VS Code, Windsurf, Gemini CLI and any other MCP client.

https://mcp.fictura.co/mcp

Streamable HTTP, stateless, JSON responses. https://api.fictura.co/mcp serves the same server.

What your agent can do

More: "Which campaigns paid back this month?" (get_acquisition_report), "Which experiment is winning, and how sure are we?" (list_experiments), "Are Universal Links set up right?" (get_link_infrastructure).

Connect

One-click

Both buttons add the URL only; sign in with your Fictura account when the editor asks. If the buttons do nothing on your system, open these links directly:

cursor://anysphere.cursor-deeplink/mcp/install?name=fictura&config=eyJ1cmwiOiJodHRwczovL21jcC5maWN0dXJhLmNvL21jcCJ9
vscode:mcp/install?%7B%22name%22%3A%22fictura%22%2C%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fmcp.fictura.co%2Fmcp%22%7D

Claude (claude.ai, Claude Desktop, Cowork)

1. Open Customize → Connectors, select + Add, then Add custom connector.

2. Name it Fictura, paste https://mcp.fictura.co/mcp and select Continue.

3. Keep the detected sign-in settings, select Add, then connect and sign in with Fictura. To use an MCP key instead, choose No sign in and add the key under Request headers as X-API-Key.

On Team and Enterprise plans an Owner adds the connector first under Organization settings → Connectors, then each member connects.

ChatGPT

1. Go to chatgpt.com/plugins, select +, then Add custom MCP server.

2. Enter https://mcp.fictura.co/mcp and choose OAuth for authentication.

3. Select Create as a plugin, then sign in with Fictura.

Your account or workspace policy must allow custom MCP servers.

Claude Code

Install the plugin from this repository. It adds the server and a skill that makes Claude read your app's real setup before it writes integration code:

claude plugin marketplace add Apex-Byte-Technologies/fictura-mcp
claude plugin install fictura@fictura

Or add only the server:

claude mcp add --transport http fictura https://mcp.fictura.co/mcp

Then run /mcp, pick fictura and sign in. To use an MCP key instead:

claude mcp add --transport http fictura https://mcp.fictura.co/mcp \
  --header "X-API-Key: $FICTURA_MCP_KEY"

Codex (CLI, IDE extension, ChatGPT desktop app)

codex mcp add fictura --url https://mcp.fictura.co/mcp
codex mcp login fictura

With an MCP key instead of sign-in, keep the key in an environment variable:

export FICTURA_MCP_KEY=fk_mcp_...
codex mcp add fictura --url https://mcp.fictura.co/mcp --bearer-token-env-var FICTURA_MCP_KEY

The same thing in ~/.codex/config.toml:

[mcp_servers.fictura]
url = "https://mcp.fictura.co/mcp"
bearer_token_env_var = "FICTURA_MCP_KEY"

Cursor

Use the button above, or add this to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "fictura": {
      "url": "https://mcp.fictura.co/mcp"
    }
  }
}

With an MCP key, add "headers": { "X-API-Key": "${env:FICTURA_MCP_KEY}" } to the fictura entry.

VS Code

Use the button above to sign in with Fictura. To use an MCP key instead, add this to .vscode/mcp.json; VS Code asks for the key once and stores it securely.

{
  "inputs": [
    {
      "type": "promptString",
      "id": "fictura-mcp-key",
      "description": "Fictura MCP key (fk_mcp_...)",
      "password": true
    }
  ],
  "servers": {
    "fictura": {
      "type": "http",
      "url": "https://mcp.fictura.co/mcp",
      "headers": { "X-API-Key": "${input:fictura-mcp-key}" }
    }
  }
}

Windsurf

Open the Cascade panel's ... menu, then Open MCP config file, and add:

{
  "mcpServers": {
    "fictura": {
      "serverUrl": "https://mcp.fictura.co/mcp",
      "headers": { "X-API-Key": "${env:FICTURA_MCP_KEY}" }
    }
  }
}

Gemini CLI

gemini extensions install https://github.com/Apex-Byte-Technologies/fictura-mcp

The installer asks for an optional MCP key and keeps it in your system keychain. Change it later with gemini extensions config fictura.

Claude Desktop with a local bridge (npx)

For clients that only run local (stdio) servers, the @fictura/mcp package bridges to the hosted server. In Claude Desktop, open Settings → Developer → Edit Config and add:

{
  "mcpServers": {
    "fictura": {
      "command": "npx",
      "args": ["-y", "@fictura/mcp"],
      "env": { "FICTURA_MCP_KEY": "fk_mcp_..." }
    }
  }
}

The bridge reads FICTURA_MCP_KEY and, optionally, FICTURA_API_BASE (default https://api.fictura.co). Claude Desktop also supports the custom connector above, which needs no local install.

Authentication

Without sign-in or a key, only the three documentation tools work: search_docs, list_docs and read_doc. Every other tool answers with how to connect.

A key is read-only unless you tick Can edit draft paywalls when you create it (those keys start with fk_mcpw_). The AppsFlyer import needs a key created with Can connect and import data. App data over MCP needs an active Fictura subscription with AI access.

Tools

44 tools and one prompt. "Read" tools change nothing.

Prompt: integrate_fictura_sdk (Integrate the Fictura SDK) walks the agent through wiring @fictura/sdk into an Expo / React Native app with the app's real credentials.

Security

• The app comes from your sign-in or key, never from the agent. No tool takes an app id, so there is no argument an agent could pass to read another app's data. A sign-in reaches only the one app you chose on the consent screen.

• Drafts never go live. The paywall and onboarding tools create and edit drafts only. Saving a live paywall or flow is refused, and going live is a click in the Fictura dashboard. Every save is a new version you can roll back; the history marks it mcp: <note>.

• The editor stays yours. editor_set_doc changes the canvas of a Studio editor you paired with a one-time code. It does not save; you see the change, can undo it, and save it yourself.

• Other writes are opt-in. update_error_issue works only after you turn on Let MCP keys change issues in the app's Issues settings. start_appsflyer_import needs a key created with Can connect and import data.

• Revocation is immediate. A revoked or invalid key is rejected on its next request with an error, never silently downgraded.

• Keep keys out of code. MCP keys (fk_mcp_...) read revenue and user data: store them in environment variables or your client's secret storage, never in a repository. The SDK key that get_app_setup returns (gk_...) is different: it is publishable and safe to ship in your app.

Report a vulnerability as described in SECURITY.md.

This repository holds the public listing files for the hosted server. The server itself runs at Fictura; there is no server code here.
