fal-mcp-server: Hook for Claude Code

.claude/settings.json

PreToolUse is a hook for Claude Code from luminarylane/fal-mcp-server. Its token cost is not measured, scanned A, original, MIT.

Automated checks that run before selected web searches and file changes made by the coding agent. They can adjust a search query and create a backup before editing a file.

In plain words
What is it for?
Use them to add a year to undated web searches, back up files before changes, and run checks around the agent’s tool use.
Why use it?
They help prevent searches from missing the current year and reduce the risk of losing earlier file contents during edits.

Hook for Claude Code

Written for Claude Code: PreToolUse hook event.

This is luminarylane/fal-mcp-server's own configuration. It tells Claude Code how to work on fal-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything fal-mcp-server configures →

Part of the fal-ai plugin — 3 hooks, 6 MCP servers shipped together

One of 4 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 3 are separate, each on its own page.

Reuse

Borrowing it

Nothing to install: this file belongs to luminarylane/fal-mcp-server. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

Copy the file
curl -O https://raw.githubusercontent.com/luminarylane/fal-mcp-server/main/.claude/settings.json
Clone the repo
git clone --depth 1 https://github.com/luminarylane/fal-mcp-server

Made for: Claude Code.

Or install fal-ai, the plugin that ships this one along with the rest of its 3 hooks, 6 MCP servers.

Security

Grade A, and why

PreToolUse 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 8d ago.

A static scan of the commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

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.

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.
