Score50
How is this score calculated?
Weighted across six dimensions, scored 0-100.
Provenance (25): listed in an official or curated registry.
Installability (25): a runnable install command beats a declared transport, which beats a source checkout.
Maintenance (20): recency of the last push; archived entries score zero here.
Adoption (20): repository stars on a log curve.
Documentation (10) and description quality (10): parsed manifest or SKILL.md frontmatter, and a real description rather than a placeholder.
Dimensions a source cannot supply — registries publish no stars or license — are excluded from the entry's own average instead of counted as zero, so entries stay comparable across sources.
Security signals subtract up to 20. Scores are recomputed on every daily ingest.
Open-source AI co-browsing browser for macOS and Linux. Let Claude Code, Codex or any MCP agent act inside your logged-in accounts — off by default, granted per tab, killable instantly, and written to a hash-chained audit log. The agent never gets your cookies, passwords or profile.
Browser automation MCP server that does not get blocked. Anti-detect Firefox (Camoufox), sign-in-once profiles, and mandatory session isolation between conversations.
Token-efficient browser MCP server: headless Chrome in Docker that captures everything (console / network / IndexedDB / snapshots) and lets the model query on read. 56 tools across full / slim / gateway mount modes.
Unofficial, read-only MCP server for public kleinanzeigen.de listings: search and read listings via a local Patchright browser. No login, no account, no messaging. Not affiliated with Kleinanzeigen.
Catches stale and wrong money figures in AI agents' answers before customers see them: 102 IRS, SSA and Medicare figures by year, each with its source. pip install fin-assist, MCP server, browser check.
Official Cursor plugin for Vertiso Memory: add the remote, user-owned memory MCP server plus the session skills in one step. Durable recall, hybrid search, and cross-session handoffs and checkpoints, with browser OAuth and no API key to paste.
Vertiso Memory plugin for OpenAI Codex: connect the remote, user-owned memory MCP server plus session skills directly, without the store or the CLI. Durable recall, hybrid search, and cross-session handoffs, with browser OAuth and no API key to paste.
Open-source engine that lets AI agents use a browser: an MCP server that shows pages as compact text, with secrets and prompt injections kept away from the model.
High-performance, token-efficient Chromium browser automation for AI coding agents. Powered by a lightweight native Rust MCP Server and a Manifest V3 Google Chrome Extension.
Local RAG search and MCP server for AI agents like Claude Code: hybrid BM25 + semantic search with reranking over Markdown and Obsidian notes, PDF, Office files and emails. Backlinks, metadata filters, browser UI. Runs on your own GPU or CPU: no cloud, no API keys.
