Tools & capabilities
Localhost MCP tools 5
list_dev_serversRead-only. Lists every local development server (next, vite, nuxt, remix, astro, rails, django, flask, express, deno, bun, etc.) currently LISTENING on a TCP port. For each: port, pid, process name, command line, working directory, project name, detected framework, uptime, memory (MB), CPU %, and owning user. Uses `lsof` on macOS/Linux and `netstat` on Windows; on Windows the cwd/framework fields are limited. Takes no arguments. Returns `{ count, servers[] }`.port_infoRead-only. Inspects a single TCP port and reports the dev server holding it (same fields as `list_dev_servers`). If nothing is listening, or the listener is not a recognised dev process, returns `{ port, status: "free" }`. Useful for answering "what's on :3000?" before starting or killing something.kill_serverTerminates a local dev server by `pid` or `port`. DESTRUCTIVE. Safe by default: with no `confirm`, this is a DRY RUN — it reports what it would kill and changes nothing. Pass `confirm: true` to actually terminate: sends SIGTERM, waits up to 5s, then escalates to SIGKILL (or SIGKILL immediately if `force: true`). Refuses PIDs below 1000 and processes that don't look like dev servers. Provide exactly one of `pid` or `port`. Returns what was (or would be) killed and the signal used.find_zombiesRead-only. Flags dev servers that look abandoned — all three of: uptime > 6h AND CPU < 1% AND memory > 100MB. By default it excludes known always-on noise (VS Code server, language servers, other MCP servers, postgres/redis, sidekiq, etc.); set `include_excluded: true` to also list those. Each candidate comes with the reasons it matched. This tool never kills anything — pass results to `kill_server`. Returns `{ count, candidates[] }`.port_conflictRead-only. Diagnoses an `EADDRINUSE` situation: given a port, returns the dev server currently blocking it plus 5 free alternative ports nearby. Use it when a `listen EADDRINUSE` error fires and you want both the culprit and a port to switch to.

search_guideSearch the Claude Code Ultimate Guide by topic, keyword, or question. Covers features, hooks, agents, MCP, skills, commands, and best practices. Use this FIRST for any Claude Code question instead of web search.read_sectionRead a section from a guide file (markdown, YAML, examples). Supports pagination via offset, or a "#heading-slug" anchor to jump straight to a section (as returned by search_guide()). Use after search_guide() to fetch the full content at a specific location.list_topicsList all top-level topics and categories in the Claude Code Ultimate Guide. Useful for exploring what the guide covers before searching.get_exampleFetch a production-ready template or example from the guide (agents, skills, commands, hooks, scripts). Pass a partial name to search for matching examples.get_changelogReturn the last N entries from the Claude Code Ultimate Guide CHANGELOG. Shows what changed in the guide itself (not Claude Code CLI releases — use get_release() for that).get_digestReturn a digest of guide and Claude Code CLI changes for a given period. Combines guide CHANGELOG entries + official Claude Code releases in the time window.get_cheatsheetReturn the Claude Code cheatsheet — a compact 1-page reference covering the most important commands, shortcuts, config options, and workflows.list_examplesList all production-ready templates in the guide by category (agents, commands, hooks, skills, scripts). Use get_example(name) to fetch the content of any specific template.get_releaseGet details about Claude Code CLI official releases. Pass a version to get a specific release, or omit to get the latest and recent history.compare_versionsShow what changed between two Claude Code CLI versions. Lists all releases in range with aggregated highlights and breaking changes.get_threatLook up a specific threat by ID from the security threat database. Supports CVE IDs (e.g. "CVE-2025-53109") and technique IDs (e.g. "T001").list_threatsBrowse the security threat database. Without a category, returns a summary with counts. With a category, returns the full list for that section.- +5 more on the listing page
