Advanced token search using a structured FilterExpression. Build arbitrary AND/OR filter trees across all filterable token fields. Two node types: Condition (leaf): {
AI agents call advanced_search_tokens to retrieve information from TDC MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data about tokens using filter conditions. It has no side effects, creates no data, executes no code, and performs no destructive or financial operations. It is a search/query function comparable to its sibling tools like get_tokens_batch and list_* functions. Classification as Read is appropriate.
From the tool's definition Tool description states 'Advanced token search' and 'Build arbitrary AND/OR filter trees across all filterable token fields.' All sibling tools are read-only queries (get_*, list_*).

Advanced token search using a structured FilterExpression. Build arbitrary AND/OR filter trees across all filterable token fields. Two node types: Condition (leaf): {. It is categorised as a Read tool in the TDC MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TDC MCP Server MCP server in PolicyLayer and add a rule for advanced_search_tokens: 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 TDC MCP Server. Nothing to install.
advanced_search_tokens 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 advanced_search_tokens 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 advanced_search_tokens. 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.
advanced_search_tokens is provided by the TDC MCP Server MCP server (truedungeoncompanion/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
