MCP server that searches Baseline status using Web Platform API

Semantic search over the StitchAPI documentation (the hosted docs MCP): `search_docs` returns the most relevant doc sections with deep links, `get_doc` fetches a full page. Hosted endpoint `https://stitchapi.dev/api/mcp`, no auth.

Production-grade MCP server for web search (Google, Brave, Serper, SearXNG, SearchAPI.io), content extraction (4-tier pipeline), academic/patent search, and multi-source research. Single Go binary.

MCP server that fetches YouTube video transcripts and optionally summarizes them. Supports multiple transcript formats (text, JSON, SRT, WebVTT), multi-language retrieval, and flexible YouTube URL parsing.

Querying network asset information by ZoomEye MCP Server

Self-contained SearXNG MCP server in Docker. 200+ search engines, 30+ categories, multi-page fanout, autocomplete, and engine discovery. Dual transport (HTTP + stdio), API key auth, and built-in SearXNG Web UI reverse proxy. Zero-install deploy.

This is a TypeScript-based MCP server that provides DuckDuckGo search functionality.

Self-hosted web research for MCP agents: search (SearXNG, with DuckDuckGo fallback), crawl, dense+BM25 rerank, and dedupe into a source-grounded, cited prompt. Local ONNX embeddings by default, or bring an OpenAI-compatible embedding API.

[Haunt](https://hauntapi.com/?utm_source=awesome-mcp-servers&utm_medium=listing&utm_campaign=sweep-2026-07) web extraction for AI agents: structured JSON or clean Markdown from permitted public pages, including Cloudflare-protected ones, with honest blocked/login/captcha errors instead of fabricated data

Beta - This project is in active development. APIs and features may change. A Model Context Protocol (MCP) server that enables AI assistants to interact with Anki, the spaced repetition flashcard application. Transform your Anki experience with natural language interaction - like having a private tutor. The AI assistant doesn't just present questions and answers; it can explain concepts, make the learning process more engaging and human-like, provide context, and adapt to your learning style. It can create and edit notes on the fly, turning your study sessions into dynamic conversations. More features coming soon!

**Verifiable oracle MCP server**: Platon VRF (`get_random`), Chronos VDF (`compute_vdf` / `verify_vdf`), LUMEN reputation (`get_reputation_scores`) as agent tools. Pay-per-call over AIMarket Hub; every result independently verifiable. stdio · Python · [Glama](https://glama.ai/mcp/servers/alexar76/aimarket-oracle-gateway).

Local-first persistent memory for Claude Code and Codex. Hooks capture sessions automatically, an LLM distills them into SQLite (optional SQLCipher encryption), and recall stays auditable via MCP, REST, and CLI with FTS + optional embeddings. Single Rust binary. `npm install -g @remem-ai/remem`

> [!IMPORTANT] > This repository is archived. The STDIO MCP server in this package is no longer being updated. > We now have a remote MCP server, which allows us to iterate faster on tools and provide a better experience.

Supply-chain gate for agent skills and MCP servers — scans tool definitions for poisoned instructions, pins vetted servers by content hash in a committed lock, and verifies drift in CI; the bundled truecopy-mcp proxy exposes only pinned, unmodified tools from a live server.

The first MCP server for [Malcolm](https://malcolm.fyi), the open-source network traffic analysis suite (Zeek + Suricata + Arkime + OpenSearch + NetBox). Gives AI agents structured, threat-hunting access: search and aggregate traffic, discover fields, query Suricata alerts, browse Arkime sessions, and resolve NetBox assets. Read-only by default; opt-in, audited write classes for alerts, tagging, hunts, and PCAP upload. `pip install mcp-server-malcolm`

Patent-pending semantic memory for AI agents: persistent memories with quality-gated writes, typed claims, conflict tracking and native coherence scoring. Hosted service with a free trial via OAuth sign-in, plus a local stdio bridge in `server/`.

Deterministic AI audit layer: evaluates LLM/agent outputs against configurable policies (jailbreak, safety, quality, wallet, trade, MEV compliance) and writes every verdict to a tamper-evident SHA-256 hash chain — metadata only, never raw content. 17 tools including a full crypto-trading compliance suite. Pay-per-call via x402 (USDC on Base), from $0.01. `mcp.fronesislabs.com/mcp`

Cross-repository code knowledge graph MCP server for Java, Kotlin, JavaScript, and TypeScript. Indexes source into embedded KuzuDB via tree-sitter; 30+ tools for call-flow tracing, multi-hop taint analysis (OWASP/CWE/PCI/STIG reports), entry-point reachability filtering, performance hotspot detection, and license compliance — without reading source files. 95% fewer tokens vs source-reading baseline. `pip install orihime`

Security & trust layer for AI agents. Scan an MCP server or skill *before* you install it (`scan_mcp_plugin`, `scan_skill`) — flags exfiltration, prompt-injection sinks, dangerous capabilities, install hooks and obfuscation → PROCEED/CAUTION/BLOCK. Plus `vet_endpoint` (endpoint safety verdict before an agent calls or pays it) and 25 more tools: vuln scans, threat intel, compliance (SOC 2/ISO 27001/HIPAA), code security (SAST/secret/dependency), identity — 28 total. Per-call billing via API key or x402 USDC on Base; free discovery tier.

Rust infrastructure diagnostics MCP server for AI agents: DNS checks, TLS certificate chain inspection, email security, global DNS propagation, and DNS latency benchmarking.

56 deterministic fact-checkers in one server (IBAN, VAT, VIN, GTIN/barcodes, national & tax IDs, crypto addresses, phone, dates, holidays) — verify the structured facts an agent emits against checksums and curated data.

Allow Claude to create flashcards for you with the official Model Context Protocol (MCP) for Rember. Rember helps you study and remember anything you care about by scheduling spaced repetition reviews. - Create flashcards from your chats _"... I like your answer, help me remember it"_ - Create flashcards from your PDFs _"Create flashcards from chapter 2 of this PDF"_ To run the Rember MCP server using npx, use the following command: Make sure to replace YOUR_REMBER_API_KEY with your actual Rember api key, which you can find in your Settings page. The API key should follow the format rember_ followed by 32 random characters.
