Как установить Llm Kernel?

Скопируйте на этой странице конфигурацию stdio для Cursor, Claude Desktop, Claude Code или VS Code. Она использует установку издателя, а не прокси PlugMCP.

Нужен ли API-ключ для Llm Kernel?

В этой записи не указано обязательных переменных окружения.

Какой транспорт использует Llm Kernel?

Llm Kernel работает локально через stdio.

MCP-сервер Llm Kernel | PlugMCP

Feature	Description	Default
`provider`	Provider catalog, model descriptors, pricing	✅
`rustls-aws-lc-rs`	TLS provider for every reqwest-backed feature (aws-lc-rs; needs a C toolchain to cross-compile)	✅
`rustls-ring`	ring TLS provider — no cmake/nasm (a plain C compiler suffices); llm-kernel installs the process-default provider itself (mutually exclusive with `rustls-aws-lc-rs`, not in `full`; see #93)
`client-async`	Async LLM client (reqwest) with streaming
`discovery`	Dynamic model discovery (models.dev, Ollama, OpenAI-compat)
`discovery-async`	Async model discovery — `DiscoverySource` trait over reqwest
`secrets`	SecretVault credential management
`store`	SQLite init helpers (WAL, FTS5, schema versioning) + `KvStore`
`config`	TOML config loader
`graph`	Knowledge graph — `GraphBackend` trait, SQLite impl, FTS5, smart recall, BFS, migrations, graph algorithms (PageRank, community, shortest-path, similarity)
`graph-async`	Async graph wrappers (requires tokio)
`graph-pool`	Multi-connection async graph pool (`AsyncPoolGraph`, WAL concurrency)
`graph-cjk`	CJK-aware graph search via Rust-side segmentation (no schema change)
`graph-pg`	PostgreSQL `GraphBackend` (`PgGraph`) + SQLite↔PostgreSQL migration CLI
`graph-pg-tls`	TLS-enabled `PgGraph` connections (`connect_native_tls` / `connect_tls` / `connect_config_tls`)
`mcp`	MCP server — JSON-RPC 2.0 dual-era (2026-07-28 stateless + legacy 2025-06-18 → 2024-11-05), stdio transport, tools/resources/prompts, async handlers, Bearer auth
`mcp-http`	MCP remote transport — Streamable HTTP (axum + tokio)
`cache`	LLM response cache — `CacheClient` over `KvStore`
`tokens`	Token estimation, budgeting, and sentence-aware document chunking
`install`	AI tool installation wizard
`search`	Hybrid search — `SearchProvider` trait, RRF / weighted-sum / CombMNZ fusion
`embedding`	Embedding provider trait + cosine similarity + `AsyncVectorIndex` trait (async counterpart to `VectorIndex`)
`embedding-openai`	OpenAI text-embedding client (sync HTTP)
`embedding-fastembed`	Local ONNX embedding via fastembed-rs (44 models)
`embedding-fastembed-qwen3`	Qwen3 embedding via candle backend
`embedding-fastembed-nomic-moe`	Nomic V2 MoE embedding via candle backend
`embedding-fastembed-directml`	DirectML GPU execution provider for `FastembedProvider` (Windows only)
`embedding-fastembed-coreml`	CoreML GPU/ANE execution provider for `FastembedProvider` (macOS only) — `new_with_coreml()` accelerates bge-m3
`embedding-metal`	Metal GPU acceleration for the candle providers (`Qwen3Provider`/`NomicMoeProvider`) on Apple Silicon — `new_metal()` (macOS only; combine with `embedding-fastembed-qwen3` / `-nomic-moe`)
`embedding-mlx`	Rust-native MLX embedding on Apple Silicon (GPU via unified memory) — `MlxEmbeddingProvider`, 13 vanilla-BERT models incl. BGE-en/zh, MiniLM, e5-small, Arctic, mxbai (macOS/aarch64 only; batch-throughput path complementing `embedding-metal`)
`embedding-fastembed-dynamic-linking`	Dynamic ONNX Runtime linking (opt-in; mutually exclusive with `embedding-fastembed` and any feature implying it — for hosts where the static archive fails at release link: glibc <2.38 / older MSVC; see #50 #55)
`vector-index`	TurboQuant compressed vector index — 2-bit/4-bit, SIMD ANN search
`qdrant`	Qdrant `AsyncVectorIndex` (`QdrantVectorIndex`) for remote vector search
`elastic`	Elasticsearch `AsyncVectorIndex` (`ElasticsearchVectorIndex`) over a hand-rolled reqwest client
`pgvector`	pgvector `AsyncVectorIndex` (`PgVectorIndex`) over PostgreSQL + the pgvector extension (cosine `<=>`, HNSW index)
`federation`	Cross-engine federation — concurrent query over multiple `AsyncVectorIndex` backends with a per-backend timeout (RRF default)
`telemetry`	Enum-gated telemetry events, no PII
`safety`	Secret masking, error classification, output sanitization, prompt-injection detection
`dlp`	Data-loss prevention — deterministic content scan (secrets, Korean PII, filesystem paths), provider data policy (`DataPolicy` on `ServiceDescriptor`)
`dlp-fingerprint`	DLP L2 — cosine fingerprint matching of registered sensitive documents over any `EmbeddingProvider`
`eval`	Quality evaluation CLI — tokens, safety, embedding, search
`eval-full`	All eval modules including graph
`catalog-sync`	Catalog sync library API — fetch models.dev at runtime, merge into the catalog (`provider::sync`) with no CLI dependencies
`catalog-sync-cli`	`catalog-sync` + CLI deps (clap, anyhow) — enables the `llm-kernel-sync-catalog` binary
`full`	All features
