Zephex MCP Server — Zed Extension

Zed Extension npm License: MIT

One-click access to Zephex — a hosted MCP server with 10 developer tools — directly inside Zed's Agent Panel. No local server to run, no Docker, no port management. Just an API key.

What you get

Project intelligence — AST-aware code reading, BM25-ranked search, full architecture diagrams
Package safety — live npm / PyPI / Cargo / Maven / NuGet CVE checks and deep migration guidance
Security audits — TLS, CSP, cookies, redirects on any URL with copy-paste fix snippets
Persistent reasoning — long-running thinking sessions with drift detection and cross-session memory
Curated knowledge base — answers across databases, security, frontend, backend, auth, mobile

Files stay on your machine. Only tool calls go out to https://zephex.dev/mcp.

Setup

1. Get an API key

Sign up at zephex.dev (free tier: 300 requests / month). Open the dashboard and copy your key — it starts with mcp_.

2. Install this extension

In Zed: cmd-shift-p → zed: extensions → search Zephex → Install.

3. Add your key to `settings.json`

cmd-, (Zed settings) then click the {} icon to edit JSON. Paste:

{
  "context_servers": {
    "mcp-server-zephex": {
      "settings": {
        "zephex_api_key": "mcp_your_key_here"
      }
    }
  }
}

4. Reload

cmd-shift-p → zed: reload context servers. Open the Agent Panel — Zephex's 10 tools are now available.

Tools

Tool	What it does
`get_project_context`	Detects framework, package manager, build/test/dev/lint commands, env vars, deps, monorepo layout, entry points
`read_code`	AST-extracted symbol or full-file reading with token budgets, outline mode, and pagination
`find_code`	BM25-ranked search with AST-aware enclosing-block context, multi-query fan-out, exhaustive mode
`explain_architecture`	End-to-end architecture analysis with Mermaid diagrams (sequence, service, C4) and health scoring
`scope_task`	Plain-English task → minimal focus file set with risk assessment and reusable utilities
`thinking`	Persistent reasoning sessions with drift detection, revision tracking, branching hypotheses
`audit_headers`	HTTP / TLS / cookie / redirect security audit with fix snippets for Nginx, Caddy, Vercel, Cloudflare, etc.
`check_package`	Live npm / PyPI / Cargo / Maven / NuGet / Pub / Hex / CocoaPods / SPM version + supply-chain signals
`audit_package`	Deep package intelligence — breaking changes, CVEs, real migration steps and code diff examples
`Zephex_dev_info`	Expert knowledge base across 6 domains: databases, security, frontend, backend, auth, mobile

How it works

This extension is a thin Rust → WebAssembly shim that:

Reads zephex_api_key from your Zed settings
Uses Zed's bundled Node.js runtime to install the zephex npm package (the actual MCP stdio server)
Spawns the server with your API key injected as ZEPHEX_API_KEY

The MCP server handles JSON-RPC, keeps file reads local, and proxies tool calls to https://zephex.dev/mcp. No long-lived process, no port allocation, no admin permissions.

Compatibility

Zed 0.190+ (extension API 0.7.0)
macOS, Linux, Windows
Bundled Node.js runtime — no system Node required

Troubleshooting

Missing zephex_api_key — your settings.json is missing the key or has it under the wrong path. Confirm the structure: context_servers > mcp-server-zephex > settings > zephex_api_key. Run zed: reload context servers after edits.

Tool call returns 401 Unauthorized — API key is invalid or expired. Get a fresh one at zephex.dev/dashboard.

Extension fails to start — open cmd-shift-p → zed: open log and search for zephex or extension. The most common cause is a stale Node install in Zed's cache; reinstalling the extension fixes it.
