AI agent builders need three things: real-time web data, a memory layer, and reliable LLM calls. Tavily and Perplexity give the agent eyes on the web; Firecrawl handles deep site extraction; Pinecone or a vector-enabled Postgres gives it memory; Redis is the fast cache. Install these and your agent is production-grade on day one.
A developer building AI agents, chatbots, or autonomous workflows. Needs search, scraping, vector storage, and LLM orchestration — all as tools the agent can call.
Purpose-built search for agents — returns summarised, LLM-tuned results instead of raw SERP junk. 10x faster iteration when building a research agent.
When you need actual answers with citations, not links. Perplexity MCP gives your agent a 'senior researcher' tool for deep questions.
The best open-source scraper for agent use. Markdown output, structured extraction, and crawling — all as MCP tools. Solves the 'agent needs to read a PDF or site' problem.
Postgres with pgvector enabled — perfect memory layer for agents without the Pinecone bill. One MCP covers auth, storage, and vector search.
Tool result cache, rate limit state, and ephemeral agent memory. Redis MCP means your agent can cache a Tavily search for 24h in one line.
Agents that build code need to read repos, open PRs, and inspect issues. GitHub MCP is table stakes for any coding agent.
Build a research agent that monitors 50 competitor blogs. Firecrawl crawls each blog weekly, the content is embedded into Supabase pgvector, Tavily searches it semantically on user questions, Redis caches the last 100 queries to save on API bill. Your agent prompt is 20 lines; the MCPs do the heavy lifting. What used to be a 2-week infra project becomes a one-day build.
Typical agent dev saves 2–3 weeks on initial infra (search + scrape + vector + cache). Ongoing, ~8h/week on observability, cache management, and prompt iteration.
Run Tavily searches on scheduled topics and index the results in Supabase for trend analysis and content research.
Schedule a Firecrawl scrape of any website and store the structured results directly in a Supabase table for analysis.
Paste a research topic in Notion and an agent uses Perplexity to gather sources, summarize findings, and structure them.
When a Supabase row changes, the corresponding Redis cache key is automatically invalidated to keep your API fresh.
Parse your GitHub repos and build a Neo4j knowledge graph of files, functions, imports, and authors for code intelligence.
MCPs are a standard protocol — swap Tavily for Exa without changing agent code, just swap the MCP. Also, MCPs are discoverable by the LLM: the agent introspects available tools and picks the right one, instead of you hardcoding which API to call when.
Yes. The MCP SDK (Python/TS) lets you connect to any MCP server from your own orchestration code. LangChain, LangGraph, and OpenAI Agents SDK all have MCP integrations now.
Supabase + pgvector. One MCP install, one SQL migration to enable the extension, and you have a vector DB. Pinecone is faster at scale, but for <1M embeddings Supabase is dramatically cheaper.
Tavily returns real URLs + snippets, so hallucination risk is on your agent's summarisation. Perplexity returns pre-summarised answers with citations — lower hallucination on the answer, but you trust Perplexity's summary pipeline. Use Tavily for breadth, Perplexity for depth.
Yes — each agent gets its own MCP client with a scoped tool set. For example: a 'researcher' agent gets Tavily+Firecrawl, a 'writer' agent gets Notion+Linear. They coordinate via a shared MCP (Redis or a message queue MCP).
A technical founder (0–10 employees) building a B2B SaaS who ships code, handles billing, writes marketing, and answers support — all in the same day.
An indie hacker with a Twitter audience, a newsletter, 1–3 shipped products, and zero employees. Ships daily, markets constantly, avoids meetings.
A DevOps / SRE / platform engineer running Kubernetes, CI/CD, observability, and on-call rotations. Lives in a terminal.
