How to Use the Ayuntamiento de Barcelona (CKAN) MCP in Mastra AI
Build resilient, self-healing Mastra AI workflows that query, filter, and process Barcelona's municipal CKAN datasets.
Works with every AI agent you already use
…and any MCP-compatible client
Connect Ayuntamiento de Barcelona (CKAN) MCP to Mastra AI
Create your Vinkius account to connect Ayuntamiento de Barcelona (CKAN) to Mastra AI and route execution through our secure gateway. The platform manages server hosting, runtime updates, and security layers. Configuration requires no manual server provisioning.
Multi-step workflows for Barcelona public statistics
The `bcn_package_search` tool finds specific municipal datasets, which Mastra AI feeds directly into its workflow engine for conditional processing. If a dataset contains environmental records, your agent branches to analyze air quality; if it contains traffic data, it routes to transit analysis. You register the MCP Server tools by instantiating `MCPClient` and spreading the tools into your Mastra Agent. The workflow handles API hiccups automatically, retrying failed calls to the Barcelona catalog without crashing your execution loop.
Human-in-the-loop SQL validation for Mastra AI
The `bcn_datastore_search_sql` tool executes SQL queries against Barcelona's open datastores, but raw SQL can be unpredictable. Mastra AI lets you require explicit human approval before your agent runs these queries on the municipal database. If the agent generates a query to analyze public statistics, Mastra pauses execution and prompts you. Once approved, the agent executes the query and continues its workflow to format the municipal records.
Automated catalog syncs with error retries
The `bcn_current_packages` tool retrieves a list of active datasets and their resources from the Open Data BCN portal. Mastra's built-in retry mechanism with exponential backoff ensures your background syncs succeed even when the Barcelona API is under heavy load. If the initial request fails, the workflow backs off and retries. Your agent then uses `bcn_resource_show` to pull the latest CSV files, ensuring your local database stays up to date with the city's public metrics.
