Exa's official MCP server connects AI assistants to a search engine purpose-built for AI, using neural embeddings to match on meaning rather than keywords so agents get clean, ready-to-use content instead of a page of blue links to re-parse. The default tool set covers web_search_exa for quick topical lookups and web_search_advanced_exa for full control over domains, date ranges, and content filters, plus specialized tools for code_search (searching real-world code and GitHub), company_research (building company profiles, competitor lists, and financials), crawling/web_fetch (pulling clean content from a specific URL), people_search and linkedin_search (public professional-profile lookups), and deep_researcher_start/check for long-running multi-step research tasks backed by Exa's Research API. The server is hosted at https://mcp.exa.ai/mcp — no local process to run — and connects via one-line setup in Cursor, VS Code, Claude Code, Claude Desktop (available as a native Connector), Codex, OpenCode, Windsurf, and Antigravity, authenticated with an EXA_API_KEY from the Exa dashboard. Tool exposure is tunable per client via a ?tools= query parameter on the endpoint URL, letting teams ship narrow, purpose-built configurations (e.g. company-research-only or LinkedIn-only agents) instead of exposing the full surface, and Exa ships ready-made Claude Skills/agent definitions for common patterns like company research and people search with built-in query-variation and token-isolation guidance.

The MongoDB MCP server is the official Model Context Protocol integration from MongoDB, giving AI assistants conversational access to both MongoDB Community Server and MongoDB Atlas cloud databases. With this MCP server, developers can ask Claude, Cursor, or Windsurf to query collections with natural-language filters that translate to MongoDB query syntax, run aggregation pipelines for analytics, insert and update documents, inspect collection schemas and index definitions, list databases and collections, and even manage Atlas clusters — all without leaving the AI interface. Common workflows include debugging slow queries by asking the AI to explain query plans, generating sample data for development environments, building dynamic dashboards by asking Claude to aggregate and summarize collection data, and automating routine maintenance like dropping orphaned indexes or counting documents matching conditions. The server works with MongoDB Atlas (via Atlas connection string) and self-hosted MongoDB 4.4+ instances. Authentication uses a standard MongoDB URI. Install with: `npx mongodb-mcp-server`. Compatible with Claude Desktop, Cursor, VS Code, Windsurf, and all MCP-compliant clients. With official backing from the MongoDB team and strong community adoption, this is the definitive MCP server for MongoDB AI integration.

The PostgreSQL MCP server is an official Model Context Protocol server maintained by Anthropic that gives AI assistants read-only access to PostgreSQL databases. By connecting Claude Desktop, Cursor, or VS Code to a running Postgres instance, developers can ask natural-language questions about their data schema, run exploratory SQL queries, inspect table structures, list available schemas, and analyze query results — all without leaving their AI chat interface. The server operates in read-only mode by design, preventing any accidental data mutations, making it safe to connect against production databases for reporting, debugging, and data exploration workflows. Core tools include executing SELECT queries, listing tables and schemas, describing column types and constraints, and inspecting indexes. Setup requires a running PostgreSQL instance and a standard connection string in postgres:// format. Install via npx using the @modelcontextprotocol/server-postgres package, passing your database URI as an argument. Teams use it to power data analysis conversations, generate schema documentation automatically, debug production data anomalies by asking Claude to inspect table contents, and build ad-hoc reports through natural-language SQL generation. Works with any PostgreSQL 12+ instance including Amazon RDS, Supabase, Neon, and self-hosted deployments.

The SQLite MCP server is an official Anthropic reference implementation that gives AI assistants direct, conversational access to SQLite databases — the world's most widely deployed database engine. Through natural language, you can ask Claude or Cursor to run SELECT queries, insert and update rows, inspect table schemas, create new tables, and generate business intelligence reports without writing a single SQL statement manually. Common use cases include exploring local data files, prototyping application schemas, auditing CSV imports, running ad-hoc analytics on app databases, and letting AI agents manage lightweight structured storage during agentic workflows. The server exposes tools for query execution, schema introspection, and memo-style business insights that synthesize query results into readable summaries. It requires a path to an existing .db file as a startup argument. Install with: npx @modelcontextprotocol/server-sqlite /path/to/your-database.db. Works with Claude Desktop, Cursor, VS Code, and all MCP-compatible clients. For developers who want AI to reason directly over structured data stored locally, the SQLite MCP server is the fastest path from question to answer without leaving your AI chat interface.
