lgrep

Dual-engine code intelligence for OpenCode: semantic code search plus symbol lookup for AI agents.

Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

// key findings
21 tools verified — handlers match their declared behaviour
12 read-only tools verified — handlers contain no write/delete/exec
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
🔐
You'll be asked for 3 credentials: LGREP_GITHUB_TOKEN, GITHUB_TOKEN, VOYAGE_API_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.
configLGREP_STALENESS_DEADLINE_S
configLGREP_AUTO_REFRESH
configLGREP_TOOL_TIMEOUT_SPer-tool server-side timeout (seconds). Bounds each MCP tool invocation.
🔐 secretLGREP_GITHUB_TOKENGitHub token used by index_symbols_repo when no token is passed to the call. Lifts remote indexing from the anonymous 60/hour rate limit (shared across all sessions) to the authenticated 5000/hour limit. GITHUB_TOKEN is used as a fallback; an explicit github_token argument wins over both.
🔐 secretGITHUB_TOKENGitHub token used by index_symbols_repo when no token is passed to the call. Lifts remote indexing from the anonymous 60/hour rate limit (shared across all sessions) to the authenticated 5000/hour limit. GITHUB_TOKEN is used as a fallback; an explicit github_token argument wins over both.
configLGREP_CACHE_DIRCache directory
configLGREP_PRUNE_MIN_AGE_SGrace window (seconds) before prune-orphans will treat an ambiguous orphan (unreadable meta / missing chunks) as prunable. 0 disables grace.
configLGREP_SYMBOLS_DIRSymbol index storage directory used by lgrep index-symbols and lgrep prune-symbols.
🔐 secretVOYAGE_API_KEYVoyage API key
configLGREP_WORKTREE_DEDUPWhen set (any value), git worktrees sharing a common .git directory resolve to the same semantic cache key, eliminating duplicate embeddings and disk usage across worktrees.
configLGREP_INDEX_MAX_WALL_S
configLGREP_LOG_LEVELLog verbosity
configLGREP_AUTO_WATCHAuto-start file watchers for warmed projects
configLGREP_WARM_PATHSColon-separated projects to warm on startup
configLGREP_AUTO_WARM_DISKAuto-load all discoverable disk caches on startup when no explicit warm paths are set. Set false for large shared machines.
configLGREP_WORKER_MAX_THREADSMax worker threads for supervised blocking daemon jobs.
// quality suggestions

All four hints declared on every tool

14/21 tools missing one or more hints — search_semantic (missing: destructiveHint); index_semantic (missing: idempotentHint); status_semantic (missing: destructiveHint), +11 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool inputs are validated

20/21 tool handlers declare input schemas (95%)

Declare an inputSchema with zod/joi/yup on every tool definition.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 2 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
