prerelease-check

prerelease-check is a command for Claude Code from mizchi/lsmcp. It costs 0 tokens per session (2,226 once invoked), scanned A, original, MIT.

A checklist for verifying lsmcp before release. lsmcp is an MCP server that exposes Language Server Protocol tools, which provide code intelligence such as type information and definition lookup.

In plain words
What is it for?
Use it to test startup, list available tools, inspect types, find definitions, and run release checks after building the project.
Why use it?
It checks that the server starts, exposes its tools, and returns expected code-navigation results before publishing.

Command for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions Claude Code.

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/mizchi/mizchi/lsmcp.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

prerelease-check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Pre-release Checklist

This document outlines the verification steps to be performed before releasing lsmcp. The primary focus is to ensure that lsmcp-dev MCP functionality works correctly.

Prerequisites

  • Node.js is installed
  • Project dependencies are installed (pnpm install)
  • Build is completed (pnpm build)
  • .mcp.json has lsmcp-dev configured

1. Basic Functionality Verification

1.1 MCP Server Startup

# Verify that the MCP server starts correctly in Claude Code
# Uses the lsmcp-dev configuration from .mcp.json

1.2 Tool List Retrieval

# List all available MCP tools from lsmcp-dev server
# Verify that 13 LSP tools are available

Expected: 13 LSP tools should be listed

2. LSP Core Features

2.1 Hover Information

# Use mcp__lsmcp-dev__get_hover
# Example: Get hover info for an import statement in src/mcp/lsmcp.ts
root: /home/mizchi/mizchi/lsmcp
filePath: src/mcp/lsmcp.ts
line: 14
target: debug

Expected: Type information and documentation for the imported function

2.2 Go to Definition

# Use mcp__lsmcp-dev__get_definitions
# Example: Find definition location for functions or classes
root: /home/mizchi/mizchi/lsmcp
filePath: src/mcp/lsmcp.ts
line: <line number>
symbolName: <symbol name>

Expected: File path and line number of the definition

2.3 Find References

# Use mcp__lsmcp-dev__find_references
# Example: Search where a specific function is used
root: /home/mizchi/mizchi/lsmcp
filePath: src/mcp/_mcplib.ts
line: <line number>
symbolName: debug

Expected: List of all locations where the symbol is used

2.4 Get Diagnostics

# Use mcp__lsmcp-dev__get_diagnostics
# Get TypeScript errors and warnings
root: /home/mizchi/mizchi/lsmcp
filePath: <target file>

Expected: Detailed error and warning information if any exist

2.5 Get All Diagnostics

# Use mcp__lsmcp-dev__get_all_diagnostics
# Get errors and warnings for all files in the project
root: /home/mizchi/mizchi/lsmcp
include: **/*.ts
severityFilter: all

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

prerelease-check is a command published in the GitHub repository mizchi/lsmcp (453 stars, last pushed 10mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,226 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
