"Information about extraction techniques or processes" matching MCP connectors:

Search agent-ready sites or fetch one site's report; every capability probe-verified, dated.

Shared error→fix knowledge base for AI coding agents. Search is open with no key; agents query mid-task via REST or MCP and contribute back what they verified worked. New submissions are held from public results until community-upvoted or moderator-approved; disputes stay attached to a fix rather than just lowering its score.

Connect your AI to any database — PostgreSQL, MySQL, or SQL Server — in seconds.

For queries a model can't confidently place: resolves or declines. Built to decline, not guess.

Turn a GitHub repo or docs site into agent-ready context: pack it or search it, over MCP.

Stoic SageA

ai.stoicsage

Semantic search over the Stoic corpus — Marcus Aurelius' Meditations, Seneca's essays, and Epictetus' Discourses, Enchiridion and Fragments. Search by theme or citation, fetch any passage, or get the daily reflection. Public domain translations, no auth.

Check claims against a fact-store: consistent, contradicts, or unverifiable — with a receipt.

BedrockNewsA

com.bedrocknews

GRIN-scored news for agents: discover by verdict, pull full analysis, traverse extraction graphs.

Know whether an AI agent should REUSE or REFETCH a URL before retrieving it again.

Extract PDFs to Markdown, RAG chunks and cited tables; publish tracked Doc Links with read stats.

Parse PDF/Word/PPT/HTML to Markdown; tables as JSON, image extraction, RAG chunking, page ranges.

AI web extraction: send URLs + a JSON Schema, get clean structured data. Pay-per-use via x402.

Real-time web search with answer-ready results for Claude, Cursor and any MCP client. A Tavily alternative: same speed, 20.2% fewer tokens, higher answer quality (60.7% of decided duels won) on a public benchmark. Hosted on mcp.serpdive.com or npx serpdive-mcp.

Diffbot MCP — Knowledge Graph company enrichment + web content extraction (diffbot.com)

mcpOAuth

ai.butlerbrain

Persistent memory for AI assistants. Save once; recall from Claude, ChatGPT, or any MCP client.

Rafter holds a team's durable knowledge — skills, agents and memory files, each versioned — and serves it to AI tools over MCP. Agents search across the team's artifacts before answering questions about how the team works or what was decided, fetch full artifact text along with its citation edges (cites, cited_by, links) to explore related material, and write new learnings back as memory. Also covers workspace, team and membership management.

LLMtoMD is the memory layer for AI coding agents. It converts any document — PDF, DOCX, slides, spreadsheets, images, audio, even whole websites — into clean, structured Markdown, then exposes it over MCP so your agent can search your FRDs, specs, and API docs on demand instead of re-reading (or forgetting) them.

Your office's procedures inside Claude or ChatGPT - verified citations or an honest refusal.

Answers questions about a business using its indexed website content, with cited sources.

Illumora Craft — evidence-augmented prompt compile for agents via remote MCP (OAuth) or local stdio.
