MCP Servers

Download

This server downloads the HTML content of a given URL. It uses the httpx library to download the content.

Then it converts the HTML content to Markdown text. So it is easier for LLM to read and understand the content.

Online Search

This server uses the Google Programmable Search API to search the web for a given query. It requires an API key to be set in the environment variable GOOGLE_API_KEY and GOOGLE_SEARCH_ENGINE_ID

See Google Programmable Search API for more information.

Today

This server returns today’s date in various formats. It is used to help LLM calculate dates in relation to the current date.

For instance it will help LLM to answer about What happened at the last Tuesday?

MCP Clients

Pydantic AI

This MCP client uses the Pydantic AI model from AWS Bedrock. It requires AWS credentials to be set in the environment variables.

This is not interactive client, it loads the model and does one task to present in STDOUT.

By default it is using Claude 3.7 model from AWS Bedrock.

Slack

This MCP client extends the Pydantic AI client to work with Slack. It uses the Slack Bolt library to create a Slack app.

It requires a Slack API token to be set in the environment variable SLACK_BOT_TOKEN and SLACK_APP_TOKEN. You can create a Slack app and get the tokens from the Slack API using the manifest file src/clients/slack/manifest.yaml
