AI agents are only as capable as the tools they can use. The Model Context Protocol (MCP) gives agents structured access to external data and services — transforming chatbots into useful autonomous workers.
Here are 8 MCP tools worth adding to your agent stack.
1. BuyWhere — Product Search & Commerce API
Real-time product catalog across 2M+ products. Search, compare prices, find deals — all through a structured API.
Why it matters: Most commerce agents still scrape web pages. BuyWhere gives structured pricing, availability, and product specs in a single API call.
2. Brave Search API — Web Search
Live web search with structured results. Let your agent answer questions with current information instead of stale training data.
Best for: Research agents, fact-checking, competitive analysis.
3. Pinecone — Vector Database
Store and retrieve embeddings for agent memory, document search, and semantic retrieval.
Best for: RAG systems, long-term agent memory, knowledge bases.
4. Filesystem MCP — Local File Access
Let agents read, write, and organize files on your machine. The simplest tool with the broadest utility.
Best for: Code generation agents, document processing, data pipelines.
5. GitHub MCP — Repository Operations
Create repos, manage issues, search code, and handle pull requests — programmatically.
Best for: Dev workflow automation, code review agents, CI/CD pipelines.
6. PostgreSQL MCP — Database Access
Run SQL queries against real databases. Read schemas, execute queries, explore data.
Best for: Data analysis agents, schema exploration, dashboard builders.
7. Notion MCP — Knowledge Management
Search pages, create documents, manage databases — all through MCP.
Best for: Documentation agents, meeting note organizers, knowledge bots.
8. Playwright MCP — Browser Automation
Control a headless browser: navigate pages, click buttons, extract data.
Best for: Web scraping agents, form automation, end-to-end testing.
Building Your Stack
Start with 2-3 tools that match your agent's job. Don't overload — every tool call adds latency and cost.
The best stacks combine information (search, database), action (filesystem, browser), and domain data (commerce, docs).
