  DEFAULT_AGENTS list includes "CoinGeckoTokenInfoAgent", enabling its tools with names prefixed by "coingeckotokeninfoagent_"

• mesh_mcp_server/server.py:189-217 (registration)

  Dynamically registers each agent tool as an MCP tool with ID '{agent_id.lower()}_{tool_name}', e.g. 'coingeckotokeninfoagent_get_token_price_multi'

      for tool in agent_data.get("tools", []):
          if tool.get("type") == "function":
              function_data = tool.get("function", {})
              tool_name = function_data.get("name")
  
              if not tool_name:
                  continue
  
              # Create a unique tool ID
              tool_id = f"{agent_id.lower()}_{tool_name}"
  
              # Get parameters or create default schema
              parameters = function_data.get("parameters", {})
              if not parameters:

• mesh_mcp_server/server.py:300-319 (handler)

  MCP handler for calling the tool: parses name to get agent/tool, invokes execute_tool which proxies to Mesh API.

• mesh_mcp_server/server.py:224-262 (helper)

  Helper that sends tool call to Mesh API endpoint /mesh_request with agent_id and tool details.
