Checks for outdated packages and returns structured update information. Auto-detects package manager via lock files (pnpm-lock.yaml → pnpm, yarn.lock → yarn, otherwise npm).
Accepts file system path (path); High parameter count (11 properties)
Part of the Npm MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use outdated to create or modify resources in Npm. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call outdated repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Npm.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Other tools in the Write risk category across the catalogue. The same policy patterns (rate-limit, validate) apply to each.
Checks for outdated packages and returns structured update information. Auto-detects package manager via lock files (pnpm-lock.yaml → pnpm, yarn.lock → yarn, otherwise npm).. It is categorised as a Write tool in the Npm MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for outdated. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Npm MCP server.
outdated is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the outdated rule in your Intercept policy.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Set action: deny in the Intercept policy for outdated. 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.
outdated is provided by the Npm MCP server (@paretools/npm). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
