Supports 10+ search engines (DuckDuckGo, Bing, Google, Brave, Wikipedia, Arxiv, YouTube, Reddit) and deep page browsing. No API key required.
lawrencehui/Citio
Self-hosted AI teammate in Slack: @mention it and Claude Code or Codex investigates CloudWatch logs, runs tests, and opens pull requests. The bundled MCP server holds all credentials (GitHub, AWS, Slack) so the agent never sees keys. One-command deploy to your own AWS. MIT.
loicfontaine-max/qorami-sdk
Check an email before an AI agent sends it: returns send / ask-a-human / block, with machine reason codes and prompt-injection detection.
SurajKGoyal/amnesic
The MCP server that remembers your database — persists table/column annotations, an FK relationship graph, and searchable notes across sessions, so the model stops re-discovering your schema every time. PostgreSQL, MySQL, MSSQL, SQLite; read-only-enforced.
aradar46/reuse-before-generate
Checks whether a project idea already exists before your agent scaffolds it. Searches GitHub, npm and Python repos, drops archived/inactive results, and returns at most 3 maintained alternatives with a concrete "extend this instead" suggestion for each. The calling agent does the relevance judgement itself, so no extra API key is needed. `npx -y reuse-before-generate`

chaoz23/inkcheck
CI for [ink](https://github.com/inkle/ink) interactive-fiction stories.

Declade/lucairn-sdks
Privacy-preserving AI gateway. Sanitises PII (German + English; Microsoft Presidio + custom recognisers) before prompts reach Anthropic / OpenAI / your LLM, then emits a signed cryptographic certificate per call (Ed25519 + RFC 3161 timestamp + Sigstore Rekor anchoring).

calllint/calllint
Pre-flight security linter for MCP servers, agent tools, and skills. Scans a config *before* it runs — offline, deterministic, evidence-backed — and returns SAFE / REVIEW / BLOCK / UNKNOWN verdicts without executing the server it judges. CLI (`npx calllint scan`), MCP server (`npx calllint-mcp`), SARIF + CI gate. UNKNOWN is never SAFE.
