Part of the Ckan MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call ckan_find_portals to retrieve information from Ckan without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though ckan_find_portals only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Search the live datashades.info registry of ~950 CKAN portals worldwide. Use this tool to discover which CKAN portals exist for a country, language, or topic before querying them with other CKAN tools. **IMPORTANT — country parameter**: always pass country name in English. If the user writes in another language (e.g. "Italia", "España", "Brasil"), translate to English ("Italy", "Spain", "Brazil") before calling this tool. Args: - country (string): Country name in English (e.g. "Italy", "Brazil", "France") - query (string): Keyword to match against portal title (e.g. "transport", "health") - min_datasets (number): Minimum number of datasets (e.g. 100) - language (string): Portal default locale code (e.g. "it", "en", "pt_BR", "fr") - has_datastore (boolean): If true, return only portals with DataStore enabled (supports SQL queries) - limit (number): Max results to return (default 10, max 50) Returns: Ranked list of matching portals with URL, country, CKAN version, dataset count, and DataStore status. Typical workflow: ckan_find_portals (discover portal URL) → ckan_status_show (verify) → ckan_package_search (search datasets). It is categorised as a Read tool in the Ckan MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for ckan_find_portals. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Ckan MCP server.
ckan_find_portals is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the ckan_find_portals rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the Intercept policy for ckan_find_portals. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
ckan_find_portals is provided by the Ckan MCP server (@aborruso/ckan-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
