Genexus MCP Server

GeneXus MCP Server lets AI agents - Claude Desktop, Claude Code, Cursor, Antigravity, and any MCP-compatible client - read, edit, analyze, and refactor objects inside a GeneXus 18 Knowledge Base. It talks to the native GeneXus SDK, so the agent works with the real KB, not a copy or a parsed approximation. Its README documents 10 tools, including genexus_whoami, genexus_doctor, genexus_recipe.

People connecting documentation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in C#.

01 · Install Genexus

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add lennix1337-genexus18mcp -- npx -y genexus-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "lennix1337-genexus18mcp": {
      "command": "npx",
      "args": [
        "-y",
        "genexus-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package genexus-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.lennix1337 is GitHub-verified and matches the repo owner

03 · What Genexus can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

An agent gets 10 documented tools, including genexus_whoami, genexus_doctor, genexus_recipe, genexus_telemetry, genexus_query.

The 10 tools it gives your agent

Extracted from the project's README - what genexus lets an agent do.

genexus_whoami: - KB context, version, worker/index/database health, self-update check, next-step hints
genexus_doctor: - connection + install + cache health check
genexus_recipe: - named playbooks / self-extending macros
genexus_telemetry: - observability (metrics, latency, errors)
genexus_query: - object search (prefixes name:, type:, usedby:, parent:, …)
genexus_list_objects: - paginated object listing with aggregates
genexus_read: - read any part of an object (source, structure, rules, events, docs, pattern XML, …)
genexus_inspect: - one-shot object snapshot (metadata, variables, structure, signature, callers)
genexus_search_source: - regex/semantic search across Procedure/DataProvider/WebPanel/Transaction source
genexus_navigation: - the IDE "View Navigation" report

Latest releases

v2.46.0 · 2026-08-24

Fixed · Report Layout writes accepted again via genexus_edit / visual write paths. The input validator rejected the <Report> root that genexus_layout itself emits for Procedure Report layouts, making every round-trip…

v2.45.2 · 2026-08-24

Changed · Faster object resolution on large KBs. genexus_search and target-name lookups no longer scan the whole in-memory index when the typed probes miss - candidates are resolved through the name→objects multimap…

v2.45.1 · 2026-08-22

Fixed · genexus-mcp doctor --mcp-smoke no longer fails on a healthy server. The smoke check omitted the Accept: application/json, text/event-stream header that the gateway requires on every POST, so it always got a 406…
