utensils/mcp-nixos
MCP server providing accurate information about NixOS packages, system options, Home Manager configurations, and nix-darwin macOS settings to prevent AI hallucinations.
juyterman1000/entroly
Auditable context control plane and MCP server for AI coding agents. Compresses context 70–95% (BM25 + entropy + dep-graph knapsack), stabilizes prompt prefixes for provider cache discounts, routes easy tasks to cheaper models (RAVS Bayesian router), and verifies answers locally with WITNESS hallucination guard (0.844 AUROC, $0, ~3 ms). MemoryOS adds local budget-aware working/episodic/semantic me
zoharbabin/web-researcher-mcp
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.
BrowseAI-HQ/BrowserAI-Dev
Evidence-backed web research for AI agents. Real-time search with cited claims, confidence scores, and compare mode (raw LLM vs evidence-backed). MCP server, REST API, and Python SDK.
TyKolt/kremis
Deterministic knowledge graph MCP server. Single binary, zero LLM/embedding calls in the bridge, BLAKE3 state hashing, canonical KREX export for byte-identical audit. Local-first via redb (ACID). **Alpha**.
mopanc/depguard
Pre-install guardian for npm packages with static code analysis, supply-chain attack detection, vulnerability audit (npm + GitHub Advisory Database), AI hallucination guard, and CycloneDX 1.6 SBOM generation with VEX. 28 MCP tools. Zero runtime dependencies — the SBOM serializer is implemented natively against the public CycloneDX schema.
Chimera-Protocol/csl-core
Deterministic AI safety policy engine with Z3 formal verification. Write, verify, and enforce machine-verifiable constraints for AI agents via MCP.
jigyasudham/veto
A council of 49 specialist agents + 93 tools for every major AI CLI (Claude Code, Codex, Gemini, Cursor, Windsurf). Deterministic agents that optionally upgrade to LLM, a self-learning router, cross-CLI memory, and guards for dependency hallucinations and decision drift. No API keys; zero extra cost on subscriptions.
VrtxOmega/omega-brain-mcp
Omega Brain MCP Server. Hardened AI execution pipeline prioritizing NAEF logic constraints over narrative LLM hallucination. 15 VERITAS Build Gates for uncompromising determinism, semantic vault integration, and Tri-Node Cortex validations.
cuttalo/depscope
Package Intelligence for AI agents. 22 tools across 17 ecosystems (npm/pypi/cargo/go/maven/nuget/rubygems/composer/pub/hex/swift/cocoapods/cpan/hackage/cran/conda/homebrew) — check health, vulnerabilities (OSV + CISA KEV + EPSS), typosquats, malicious flags, alternatives, known bugs, breaking changes, stack compatibility and error-to-fix. 31k+ packages, 2.2k+ CVEs enriched. Zero auth, MIT. Remote
yanmxa/scriptflow-mcp
A script workflow management system that transforms complex, repetitive AI interactions into persistent, executable scripts. Supports multi-language execution (Bash, Python, Node.js, TypeScript) with guaranteed consistency and reduced hallucination risks.
poll-the-people/customgpt-mcp
An MCP server for accessing all of CustomGPT.ai's anti-hallucination RAG-as-a-service API endpoints.
imran-siddique/agentos-mcp-server
Agent OS MCP server for AI agent governance with policy enforcement, code safety verification, multi-model hallucination detection, and immutable audit trails.
hernaninverso/eleata-verify-mcp
Grounding / hallucination guard: verify a claim against evidence (Supported/Refuted/Not Enough Evidence) with a confidence + abstain flag, for RAG and agents. `npx -y eleata-verify-mcp`.
