KyaniteLabs/kinocut
Guardrailed video editing for AI agents with 135 MCP tools for FFmpeg editing, captions, audio, effects, Hyperframes, repurposing, resumable workflows, quality gates, and provenance receipts. Includes a Python client and `kino` CLI; runs locally with no required API keys.
Kentucky-ai/opentakeoff
Construction plan takeoff on stdio — load a plan PDF, read the title block, adopt the drawing scale (never applied silently), one-click trace rooms, and export real-world quantities (square footage, linear feet, counts) with provenance receipts. Install via NPM: `npx -y opentakeoff-mcp`
markmhendrickson/neotoma
Deterministic state layer for AI agents. Stores versioned entities (contacts, tasks, transactions, decisions) with immutable observations, full provenance, and schema-first extraction. Local-first SQLite, cross-client memory across Claude, Cursor, ChatGPT, and OpenClaw. [Website](https://neotoma.io)
sgx-labs/statelessagent
Memory with provenance tracking — records where agent knowledge originated and detects when sources change. 17 MCP tools for session handoffs, decisions, semantic search, and knowledge graph. Works across Claude Code, Cursor, Windsurf, Codex CLI, and Gemini CLI. Single Go binary, SQLite + vector search, fully local.
masondelan/selvedge
Change tracking for AI-era codebases. AI agents call it to log structured change events (entity + diff + reasoning) before the session ends, then query history with diff, blame, history, changeset, and search. Captures the intent that would otherwise evaporate.
vornicx/Midas
Local-first memory for long-horizon AI agents with no LLM at ingest — $0 per message, zero data egress, verbatim source-traceable recall. Typed belief revision, selective forgetting, and a provenance guard that blocks memory-justified destructive actions unless user-confirmed. One `midas init` wires Claude Code, Cursor, Codex, and 6 more clients to one shared SQLite memory; local web inspector and
mcpqueen/mcpqueen
The graded MCP registry: live-probes every remote server in the official registry (initialize, tools/list, schema quality, latency, provenance) and publishes evidence-backed grades — searchable by agents via its own MCP endpoint at [mcpqueen.com](https://mcpqueen.com).
smaniches/uniprot-mcp
Auditable UniProt MCP server: 41 tools over the UniProt knowledgebase (entries, features, variants, PTMs, GO terms, cross-references) with per-query SHA-256 provenance and offline replay. `uvx uniprot-mcp-server`
beeswaxpat/chronoverify-mcp
Verify a photo's capture time and provenance before an agent trusts it: cryptographic C2PA Content Credentials validation against the official trust lists, EXIF and XMP consistency checks, and classical pixel forensics fused into one typed verdict with a 0 to 100 confidence. Free keyless tier, opt-in shareable verdict permalinks, and key-gated signed PDF audit reports. Provenance validation, not a
atakanelik34/Bilinc
Hosted agent memory that keeps an audit trail. Three tools — `commit_mem`, `recall`, `status` — where each write carries provenance (which run, tool, or operator produced it), contradictions with prior state surface as inspectable changes rather than silent overwrites, and a bad run is recovered from a snapshot instead of repaired by hand. `pip install -U bilinc`
askalf/truecopy
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.
layervai/qurl-mcp
Mint, resolve, audit, and rotate expiring scope-limited access links (qURLs) for AI agents — secure URL gateway for the qURL API. 9 tools (create / resolve / list / get / delete / extend / update / mint-link / batch-create), 3 resources, 3 guided prompts. stdio transport, OIDC-attested npm provenance.
thehealthai/clarity-mcp
Condition-aware ingredient, product & supplement safety for agents, with provenance on every answer — a verdict, an evidence tier (Gold/Silver/Bronze), and a verifiable citation — across breastfeeding, pregnancy, histamine/MCAS, rosacea, HS, allergy and fertility lenses. 9 tools incl. validate_claim (fact-check a claim against curated cited sources) and check_recall (FDA/consumer recall lookup by
geowire/geowire
Location intelligence gateway across 10 providers (OpenStreetMap, OSRM, Google, Yelp, Foursquare, US Census, Kakao, Naver, Baidu, your own CSV): place search, geocoding, directions + distance matrices, travel-time isochrones, and commercial-area analysis (category density, ratings, demographics). Multi-provider merge + dedup with per-field provenance, cost budgets, and a policy engine that enforce
