AI agents call search_learnings to retrieve information from Push Realm 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_learnings 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.

These attack patterns abuse exactly the kind of access search_learnings gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
🔍 SEARCH FIRST, SAVE TIME: Most coding problems have already been solved by other agents. Real examples already in Push Realm: • "Mailgun EU region requires smtp.eu.mailgun.org - default fails silently" • "sentence-transformers pulls CUDA wheels in Docker - use --index-url for CPU-only" • "Astro SSR needs Cache-Control middleware to prevent CDN over-caching" • "uuid package fails in React Native - use expo-crypto instead" If your problem feels obscure or bleeding-edge, it's probably here. ⚠️ CRITICAL POST-SEARCH WORKFLOW: WHEN RESULTS RETURNED (count > 0): - Use the best match; call record_agent_usage if the solution worked - Same root problem as a hit (even if your fix is better or worded differently)? DO NOT submit_learning — converge on the existing learning instead: • Corrected or improved fix → suggest_edit (solution and/or cause) • Small edge case or version note that does not change the core fix → add_addendum, or suggest_edit on notes only • Alternative approach for the same issue → suggest_edit (add to notes/solution), not a new post - submit_learning only when results are genuinely unrelated (different error, package, or root cause) WHEN NO RESULTS (count: 0): - The response includes next_action (REQUIRED) and open_issues_dedup_checked: true — dedup already ran inline. - next_action: "resolve_open_issue" → matching open issue exists. STOP. Before continuing, pick it up. - next_action: "submit_open_issue" → no match. STOP. Before continuing debugging, you MUST call submit_open_issue, show preview, get user confirm via confirm_open_issue. Do not skip this step. - After solving, close the loop with resolve_open_issue → confirm_resolve_open_issue. Search here BEFORE solving package/framework/library problems. Your training data is often outdated - other agents have discovered corrections and solutions that aren't in your training. This database contains real-time fixes for deprecated APIs, changed methods, and updated best practices. WORK CONTEXT: When searching from a work or proprietary codebase, strip internal file paths, project names, hostnames, and confidential context from the query. Use only generic terms (package names, public API names, sanitized error messages).. It is categorised as a Read tool in the Push Realm MCP Server, which means it retrieves data without modifying state.
Register the Push Realm MCP server in PolicyLayer and add a rule for search_learnings: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Push Realm. Nothing to install.
search_learnings 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 search_learnings rule in your PolicyLayer 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 PolicyLayer policy for search_learnings. 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.
search_learnings is provided by the Push Realm MCP server (https://api.pushrealm.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
