Dear @olaservo @dsp-ant @cliffhall

We have created an official MCP server for our widely used financial API, Twelve Data. To help developers easily access our service via the MCP ecosystem, we’ve submitted a pull request to include our server in your MCP servers catalog (README).

We kindly request your review and approval of this contribution.

Thank you for your support.
