search_cpv

Look up CPV (Common Procurement Vocabulary — EU procurement category) codes by Polish keyword. Use this before search_tenders to find the right CPV filter. Returns code, name, division, and historical tender count.

Accepts freeform code/query input (query)

Part of the Atlasprzetargow MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

@atlasprzetargow/mcp Read Risk 2/5

AI agents call search_cpv to retrieve information from Atlasprzetargow 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 search_cpv 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.

What does the search_cpv tool do? +

Look up CPV (Common Procurement Vocabulary — EU procurement category) codes by Polish keyword. Use this before search_tenders to find the right CPV filter. Returns code, name, division, and historical tender count.. It is categorised as a Read tool in the Atlasprzetargow MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on search_cpv? +

Add a rule in your Intercept YAML policy under the tools section for search_cpv. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Atlasprzetargow MCP server.

What risk level is search_cpv? +

search_cpv is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit search_cpv? +

Yes. Add a rate_limit block to the search_cpv 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.

How do I block search_cpv completely? +

Set action: deny in the Intercept policy for search_cpv. 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.

What MCP server provides search_cpv? +

search_cpv is provided by the Atlasprzetargow MCP server (@atlasprzetargow/mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
