Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

}🟡call_tool(url, toolName, args, maxSpendUsd, allowWrite)
Proxy one tool call to a discovered remote MCP server (paid). Every call passes pre-execution guards before anything runs: tools on TOOLHAIL_BLOCKED_TOOLS are always refused; when TOOLHAIL_ALLOWED_TOOLS is set (non-empty, no "*") only listed tools may fire; write/mutating-looking tool names are refused unless allowWrite:true is passed or the tool is allowlisted; and TOOLHAIL_ARG_LIMITS can cap specific argument values per tool (e.g. daily_budget<=500) so an allowlisted broad tool still cannot push a value past its ceiling. Any refusal executes nothing and bills nothing, and every receipt records the gate decision.
