Set up a Notion API integration by creating a new integration, retrieving and pasting the secret key, and granting read, write, and insert update access to connect pages and reports.

Set up the MCP server with SQLite and attach it to cloud desktop to access the SQL database, then download, extract sample database, and verify the SQL server is running.

Connect cloud desktop to the escalate MCP server and perform SQLite database analysis with AI, running queries to find top salaries, department averages, and manager counts.

Explore MCP resources and types, including static and dynamic resources, text and binary data, URIs, mime types, and metadata, and learn duplicate resource management with prompts.

Learn to build a job search API with Rapid API, obtain an API key and free plan access, and test endpoints using curl and environment variables.

Implement the save_job tool to move a selected job from the temp data into the candidate saved folder, extracting or inferring salary and storing a structured json.

Develop MCP prompts to analyze the job market, generate personalized job recommendations, and create match reports that compare resume details with saved job data.

Build a rag system with MCP by ingesting PDFs into a chroma DB and creating embeddings with lang chain and lama. Explore gateway architecture and search across cloud and desktop.

Configure the MCP RAG server by writing server.py, installing dependencies via a virtual environment from pyproject.toml, and wiring LangChain with Ollama embedding for a vector store, plus PDF text extraction.

Implement PDF text extraction from a PDF file, folder, or URL using PyPDF2, split text into chunks with a recursive character splitter, and ingest embeddings into a chroma vector store.

Download a pdf from a url into a download directory, extract text, and ingest it using MCP tools for folder ingestion and retrieve db info and clear db.

Implement the ingest pdf mcp tool to handle pdf files, folders, and remote urls, then extract, create embeddings, chunk, and store vectors with error reporting.

Implement retrieve MCP tool to query chroma vector store, run a similarity search for top chunks with scores and metadata, and expose db_info and clear_db tools for database management.
