+`mcp-memory-server` directly interfaces with local Ollama instances (e.g. `http://192.168.1.30:11434`) via a native compiled Rust client (`server/src/ollama.rs`):
+* **Connection Handshake:** On startup and before executing LLM-enhanced tools, `mcp-memory-server` issues a **1.5-second health probe** (`GET /api/tags`).
+* **Environment Configuration (`mcp_config.json`):**
+  * `OLLAMA_URL`: Target Ollama host URL (default: `http://192.168.1.30:11434`).
+  * `OLLAMA_CODER_MODEL`: Local coding model (e.g., `qwen2.5-coder:1.5b`).
+  * `OLLAMA_REASONING_MODEL`: Chain-of-thought reasoning model (e.g., `deepseek-r1:1.5b`).
+  * `OLLAMA_VISION_MODEL`: Multimodal vision model (e.g., `qwen3-vl:2b`).
+  * `OLLAMA_EMBED_MODEL`: Dense embedding model (e.g., `nomic-embed-text:latest`).
+* **Graceful Degradation Guarantee:** If the local Ollama host is offline or unreachable, **no tool ever fails.** Every tool automatically falls back to pure Rust execution and local `redb`/`Tantivy` storage.

 # 8. GCP Infrastructure Provisioning (gcloud & Cloud Armor)
 - **Rule (Cloud Armor IP Limits):** GCP Cloud Armor security policies strictly enforce a limit of **10 IP ranges per rule** (`--src-ip-ranges`). When allowlisting large services (like Atlassian Bitbucket which has 11+ IP CIDR blocks), you MUST split the ranges across multiple rules (e.g., priority 1000 and 1001) to prevent the `Only a maximum of 10 IP ranges allowed per rule` API error.
 - **Rule (gcloud Idempotency):** When writing bash scripts to provision GCP infrastructure, NEVER use bare `gcloud ... create` commands. You MUST wrap all creation commands in existence checks (e.g., `if ! gcloud ... describe ... >/dev/null 2>&1; then ... fi`) to ensure the script is fully idempotent and can be safely retried upon failure.
+
+# 9. Rust Build System & Toolchain Resilience
+- **Rule (SChannel VPN Revocation Bypass):** To prevent `CRYPT_E_NO_REVOCATION_CHECK` errors when fetching crates over corporate VPNs, ensure `.cargo/config.toml` specifies `[http] check-revoke = false`.
+- **Rule (sccache Caching Efficiency):** When using `sccache` as `rustc-wrapper`, set `incremental = false` under `[profile.dev]` in `.cargo/config.toml`. `sccache` cannot cache incremental compilation units.
+- **Rule (sccache Daemon Recovery):** If `sccache` fails with socket error 10054 (`connection forcibly closed`), restart the daemon using `sccache --stop-server; Start-Sleep -Seconds 1; sccache --start-server` before retrying compilation.
+- **Rule (cargo-llvm-cov Toolchain Matching):** Always set `LLVM_COV` and `LLVM_PROFDATA` environment variables to the matching `rustup` toolchain LLVM binaries (`.../lib/rustlib/<target>/bin/llvm-cov.exe`) to prevent LLVM profile format version mismatches.

 ## 17. Tool Schema Discovery (Lazy Loading)
 Antigravity automatically caches all MCP tool schemas to your disk to save tokens. Do **NOT** grep or search the Rust source code to find tool schemas or arguments. To understand a tool's arguments, directly read `~/.gemini/antigravity-cli/mcp/<server_name>/<tool_name>.json`. Do NOT guess arguments. ALWAYS read the schema if you are unfamiliar with a tool to prevent invalid argument errors.
 
+## 18. Local Ollama LLM Handshake & Graceful Fallback
+`mcp-memory-server` includes a native, compiled Rust client (`server/src/ollama.rs`) that interfaces directly with local Ollama hardware (e.g. `http://192.168.1.30:11434`).
+- **Connection Handshake:** On startup and before executing LLM-enhanced tools, the server performs a **1.5-second health probe** (`GET /api/tags`).
+- **Environment Variables:** `OLLAMA_URL`, `OLLAMA_CODER_MODEL` (`qwen2.5-coder:1.5b`), `OLLAMA_REASONING_MODEL` (`deepseek-r1:1.5b`), `OLLAMA_VISION_MODEL` (`qwen3-vl:2b`), and `OLLAMA_EMBED_MODEL` (`nomic-embed-text:latest`).
+- **Synergistic Tool Enhancements:**
+  - **`log_code_change`**: Automatically uses `qwen2.5-coder:1.5b` to summarize architectural impact.
+  - **`log_error_fix`**: Automatically uses `deepseek-r1:1.5b` for root cause & solution extraction.
+  - **`read_clipboard`**: Automatically passes clipboard image bytes to `qwen3-vl:2b` for OCR/layout parsing.
+  - **`omni_search`**: Uses `nomic-embed-text` for dense vector search indexing.
+- **Graceful Fallback Guarantee:** If Ollama is offline, unreachable, or times out (>1.5s), **no tool ever fails or throws an error.** Every tool automatically degrades gracefully to pure Rust execution and local `redb`/`Tantivy` storage.
+
+## 19. Tool Discovery & WebSocket Handshake (`tools/list_changed`)
+The server implements the full Model Context Protocol (MCP) JSON-RPC specification for tool discovery and live updates:
+- **`tools/list` Endpoint:** Primary clients query this endpoint during initialization to discover all registered tools, schemas, and argument types.
+- **Dynamic Handshake Notification (`notifications/tools/list_changed`):** When the backend server restarts or modifies its tool definitions, it broadcasts a WebSocket `notifications/tools/list_changed` JSON-RPC notification. Light stubs (`mcp-memory-stub`) automatically receive this event and refresh the host CLI's tool catalog in real time without disconnecting or restarting the CLI context.
