Part of the Gopeak MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call tool-catalog to retrieve information from Gopeak 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 tool-catalog 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.

[compact alias of tool_catalog] Discover available tools including hidden legacy tools. Use query to search by capability keywords. Results include group categorization (core/dynamic). Matching dynamic groups are auto-activated and become available immediately. Core groups (always visible): core_meta, core_project, core_editor, core_scene, core_script, core_class, core_signal, core_resource, core_export, core_runtime, core_visualizer, core_diagnostics. Dynamic groups (on-demand): scene_advanced, uid, import_export, autoload, signal, runtime, resource, animation, plugin, input, tilemap, audio, navigation, theme_ui, asset_store, testing, dx_tools, intent_tracking, class_advanced, lsp, dap, version_gate.. It is categorised as a Read tool in the Gopeak MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for tool-catalog. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Gopeak MCP server.
tool-catalog 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 tool-catalog 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 tool-catalog. 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.
tool-catalog is provided by the Gopeak MCP server (gopeak). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
