What is the NationBuilder MCP Server?
Connect your NationBuilder account to any AI agent and take full control of your community orchestration and campaign mobilization through natural conversation. NationBuilder is the leading software for political campaigns and non-profits, and this integration allows you to retrieve signup metadata, record donations, and monitor petition engagement directly from your chat interface.
What you can do
- Signup & Audience Orchestration — List all managed signups and retrieve detailed profile metadata programmatically to ensure your voter or donor database is always synchronized.
- Donation Lifecycle Management — Record and monitor financial contributions directly from the AI interface to track campaign fundraising goals.
- Petition & Advocacy Intelligence — Access and monitor active petitions and retrieve supporter metadata via natural language to drive better mobilization efficiency.
- Community Tagging Control — List and search through your nation's tags and custom people lists to maintain a clear overview of your segments using simple AI commands.
- Operational Monitoring — Track system responses and manage event metadata to ensure your campaign workflows are always optimized.

Frequently asked questions
Can my AI automatically find the details for a specific signup by their email?
Yes! Use the search_signups tool. Provide the email address, and your agent will respond with complete metadata for the profile, including tags and unique ID in seconds.
How do I find my Nation Slug?
The Nation Slug is the unique prefix in your NationBuilder URL (e.g., if you log in at mynation.nationbuilder.com, your slug is mynation).
Does this support the NationBuilder API v2?
Yes, this MCP server is built specifically for the NationBuilder REST API v2, utilizing the modern JSON:API specification for all data interactions.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
