Search Stack Overflow questions (keyless). Each result: title, link, score, answer count, answered flag, view count, tags, creation date, and question id. Sort by relevance, votes, activity, or creation. For coding agents that need authoritative Q&A on errors, APIs, and language features.
AI agents call dev.stackoverflow-search to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure data retrieval tool that queries Stack Overflow's public API for question metadata. It does not create, modify, delete, or execute any code. The severity is low because misuse would only result in retrieving unwanted information, with no destructive or financial consequences.
From the tool's definition Tool description states it 'Search[es] Stack Overflow questions' and returns metadata like 'title, link, score, answer count, answered flag, view count, tags, creation date, and question id.' No modification, deletion, or execution capabilities are mentioned.

Search Stack Overflow questions (keyless). Each result: title, link, score, answer count, answered flag, view count, tags, creation date, and question id. Sort by relevance, votes, activity, or creation. For coding agents that need authoritative Q&A on errors, APIs, and language features. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for dev.stackoverflow-search: 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 Mcp. Nothing to install.
dev.stackoverflow-search 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 dev.stackoverflow-search 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 dev.stackoverflow-search. 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.
dev.stackoverflow-search is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
