BugSmash MCP

Local Model Context Protocol server that lets an LLM read and manage BugSmash reviewer feedback without ever seeing your BugSmash API key.

LLM (Claude) --MCP--> bugsmash-mcp --HTTPS + X-API-Key--> https://api.bugsmash.io/api/v2

Install

npm install -g @mxrcochxvez/bugsmash-mcp

Or run without a global install via npx (see connector config below).

Requires Node.js 18+.

Generate an API key

1. Sign in at tools.bugsmash.io.
2. Open your profile menu → Settings.
3. Find the API Key section and copy the key.
4. Treat it like a password. If it leaks, regenerate it immediately from the same settings page.

Official auth docs: docs.bugsmash.io/authentication

Set BUGSMASH_API_KEY (do not commit it)

Export the key in your shell — never put it in a committed file.

export BUGSMASH_API_KEY="your-key-here"

macOS / Linux (zsh), persist for your user:

echo 'export BUGSMASH_API_KEY="your-key-here"' >> ~/.zshrc
source ~/.zshrc

Confirm it is set (does not print the value):

test -n "$BUGSMASH_API_KEY" && echo "BUGSMASH_API_KEY is set"

Register as a user-level MCP connector

Use a user scope so the server is available in every project.

Claude Code / Claude CLI (recommended: npx)

claude mcp add --scope user bugsmash --env BUGSMASH_API_KEY=$BUGSMASH_API_KEY -- npx -y @mxrcochxvez/bugsmash-mcp

If you installed globally:

claude mcp add --scope user bugsmash --env BUGSMASH_API_KEY=$BUGSMASH_API_KEY -- bugsmash-mcp

Claude Desktop

Edit your Claude Desktop config (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "bugsmash": {
      "command": "npx",
      "args": ["-y", "@mxrcochxvez/bugsmash-mcp"],
      "env": {
        "BUGSMASH_API_KEY": "your-key-here"
      }
    }
  }
}

Prefer injecting the key from the environment your Desktop app inherits, rather than pasting it into a synced config file when possible.

Cursor

Add a similar MCP entry: command npx, args ["-y", "@mxrcochxvez/bugsmash-mcp"], and BUGSMASH_API_KEY under env.

Tools

| Tool | BugSmash API | Purpose | | --- | --- | --- | | list_projects | GET /projects | Paginated project list (find projectId) | | get_project | GET /project/{projectId} | Project details + versions | | list_feedback | GET /comments?projectId | All reviewer comments on a project | | get_feedback | GET /comment/{commentId} | Single comment (+ replies) | | update_feedback | PATCH /comment/{commentId} | Update text / status / priority / privacy | | list_replies | GET /comment/{commentId}/replies | Thread replies | | post_reply | POST /reply | Reply on a thread |

Base URL: https://api.bugsmash.io/api/v2
Auth header: X-API-Key (never a tool argument).

Typical flow: list_projects → list_feedback → optionally update_feedback / post_reply.

Security note

• The API key is read only from BUGSMASH_API_KEY.
• It is never accepted as a tool parameter.
• It must never be logged, printed, masked-partially in errors, or returned in tool responses.
• On startup, a missing key exits with the generic message BUGSMASH_API_KEY is not set.
• All HTTP calls go through one helper that attaches X-API-Key; request headers are not surfaced on errors.
