Compatible with every major AI agent and IDE
What is the Paraíba Open Data MCP Server?
The Paraíba MCP Server connects your AI agent to the official Dados Abertos portal of the State of Paraíba. This integration allows for real-time auditing and analysis of public finances, government contracts, and personnel spending through natural conversation.
What you can do
- Budget & Finance — Query budget allocations (
get_dotacao), liquidations (get_liquidacao), and revenue execution or forecasts. - Public Spending — Inspect commitment notes (
get_empenho), daily allowances for public servants (get_diarias), and payment authorizations. - Human Resources — Access detailed payroll summaries (
get_folha_pagamento) to monitor state personnel costs. - Contracts & Agreements — List and analyze government contracts (
get_contratos) and outstanding payables (Restos a Pagar). - Institutional Structure — Retrieve information about management units, government actions, and resource sources.
How it works
- Subscribe to this server
- Enter your API access token for the Paraíba data proxy
- Start auditing public data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Journalists & Researchers — Instantly aggregate spending data for investigative reports without manual CSV exports.
- Public Auditors & Lawyers — Cross-reference contracts and payment authorizations directly from your workspace.
- Engaged Citizens — Exercise transparency by asking simple questions about how state resources are allocated.

Frequently asked questions
Can I see the total payroll for a specific month and year?
Yes! Use the get_folha_pagamento tool by providing the exercicio (year) and mes (month). The agent will return a summary of personnel spending for that period.
How do I check government contracts for a specific year?
You can use the get_contratos tool with the exercicio parameter. This will list the contracts registered in the state's system for the requested year.
Is it possible to track outstanding debts (Restos a Pagar)?
Yes, the get_restos_a_pagar tool allows you to fetch data on expenses that were committed but not yet paid from previous fiscal years.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Paraíba Open Data MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
