BillDog.io MCP ServerVerifiedFeatured

What is BillDog?

BillDog is a monetization and growth platform for mobile and web apps: native paywalls, subscriptions and in-app purchases, entitlements, A/B experiments, feature flags, analytics, surveys and messaging, behind one SDK. The BillDog MCP server lets your AI agent read and set up a BillDog project directly.

How to connect

Add the server URL to any client that supports remote MCP servers (Streamable HTTP):

{ "mcpServers": { "billdog": { "url": "https://api.billdog.io/mcp" } } }

The first tool call opens Sign in with BillDog in your browser. You pick one project and choose whether the agent may only read, also create and edit, or also publish. No API key is needed. For clients without OAuth, a read-only bd_mcp_ key works as a Bearer token.

What you can ask

• "Check my BillDog project setup and tell me what is missing"
• "Create a monthly and an annual subscription and attach them to the Pro entitlement"
• "Build a paywall from a template, preview it, and show it at the onboarding placement"
• "Run an A/B test between two paywalls and tell me which one converts better"
• "Roll out the new_onboarding feature flag to 10% of users"
• "What was revenue per user from last week's paywall views?"

Tools (57)

• Setup and diagnostics: setup status, recent SDK activity, SDK integration guides
• Catalog: products, entitlements, offerings, packages, placements
• Paywalls: templates, AI design, preview, publish and unpublish
• Experiments and feature flags: create, start, stop, ship the winner, per-variant results
• Analytics: queries, saved views, cohorts, event names
• Engagement: surveys, campaigns, journeys, message templates
• Projects: projects and public SDK keys

Safety

• New products, offerings, placements and paywalls start as drafts or inactive.
• Publishing, starting an experiment or changing a live offering needs the publish permission. On projects with live traffic, an owner or admin must approve it.
• Every write is recorded in the project's audit log, attributed to the agent and the user who connected it.
• You can disconnect the agent from the BillDog dashboard at any time.
