Open-source MCP server that audits programmatic SEO sites for SpamBrain risk — doorway clusters, near-duplicates, thin content — grouped by template. Clusters URLs into templates, samples pages from each, and returns a per-template verdict with risk score and fix manifest. Fix one template, fix thousands of pages. MIT.

63-layer continuous-time Symplectic Neural ODE computing topological invariants of real market signals. 256-dim feature space with non-Abelian gauge field geometry. 27 data products (property intelligence, DAG manifold computation, federal contracts, distressed real estate) with autonomous Stripe purchase. 500K out-of-pocket validated embeddings. Free tier available.

Zhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.

Auditable, self-improving knowledge & memory for AI agents, served over MCP. Citation-enforced answers (no source, no claim), a replayable why-trace per answer, and a judge-gated loop that promotes validated knowledge. Zero-key local embeddings (bge-m3), hybrid vector + BM25 retrieval, scoped fail-closed bearer auth, and multi-tenant row-level security — self-hosted on Postgres alone. Apache-2.0. Reference implementation of the Agentic Product Standard.

143 local tools for Claude, Cursor & ChatGPT — Mail, iMessage, Microsoft Teams, Slack, WhatsApp, Calendar, OneDrive, Outlook, OmniFocus, Notes, Finder and Office docs. 100% local, no API keys. Reaches what cloud connectors can't. Mac + Windows.

mneme is an open-source, vault-native memory layer for Claude Code and any MCP client. Your Markdown files are the source of truth. The index, embeddings, and knowledge graph are all derived and rebuildable. No LLM or network on the capture path. Redaction runs before every derived store. MIT licensed.

B2B enrichment API for AI agents — 89 canonical fields per person + company, each annotated with source, confidence (0-1) and freshness. One call synthesises ten sources; no per-field bills. Add https://mcp.abm.dev/mcp as a custom MCP connector (OAuth 2.1 PKCE).

A Model Context Protocol (MCP) server that integrates with Jina AI Search Foundation APIs.

Mercury is an MCP server + API where your AI agent pays for web data itself. It discovers a service, pays per call over x402 (or a free API key — no crypto needed), and gets back clean data plus an EIP-191 signed provenance receipt it can verify offline. 18 keyless services — fetch, extract, markdown, metadata, links, tables, feeds, sitemaps, DNS, diff, notarize — ~$0.003–0.02 a call, on 6 chains (Base, Polygon, Avalanche, Sei, IoTeX, peaq). npx mercury-x402-mcp for Claude / Cursor / Cline.

GraphPilot gives coding agents persistent structural knowledge of a codebase. It parses TypeScript/JavaScript with tree-sitter into a graph of symbols and call edges, then exposes that graph over MCP so the agent can recall definitions, find callers, and trace change impact without re-reading files every conversation. Local-first: no network, no telemetry, no code ever leaves your machine. Four tools — gp_index, gp_recall, gp_callers, gp_impact.

GitLab API, enabling project management

A Model Context Protocol Server connector for Perplexity API, to enable web search without leaving the MCP ecosystem.
