Part of the Claude Token Saver MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use pull_model to create or modify resources in Claude Token Saver. 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 pull_model 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 Claude Token Saver.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Download a model from the Ollama registry to local storage. Use this to install recommended models before preloading them into VRAM.. It is categorised as a Write tool in the Claude Token Saver 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 pull_model. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Claude Token Saver MCP server.
pull_model 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 pull_model 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 pull_model. 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.
pull_model is provided by the Claude Token Saver MCP server (claude-token-saver-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
