Claude Code Beacon Plugin
Register the Beacon marketplace so Claude Code can semantically search your codebase with embeddings instead of grep-only exploration.
Overview
claude-code-beacon-plugin is a plugin marketplace for the Build phase that provides Beacon semantic code search with embeddings inside Claude Code.
What is this marketplace?
- MIT-licensed Beacon plugin v1.0.0 for Claude Code
- Semantic code search using embeddings beyond literal string matching
- Keywords: semantic-search, code-search, embeddings in marketplace metadata
- Development-category plugin aimed at faster navigation in large repos
- Marketplace bundles 1 plugin: beacon version 1.0.0
- MIT license declared in marketplace manifest
Community signal: 36 GitHub stars.
What problem does it solve?
Agents stall on large codebases because keyword search misses conceptually related implementations and wastes tokens scanning irrelevant files.
Who is it for?
Indie builders and small teams on Claude Code who work in multi-package repos and need concept-level code discovery during feature work and debugging.
Skip if: Greenfield tiny repos where full-tree context fits every turn, or teams that cannot run Beacon’s indexing prerequisites locally.
What do I get? / Deliverables
After install, Claude can locate semantically related code paths faster, reducing blind grepping and shortening fix-and-ship loops.
- Semantic search results surfacing related functions, types, and modules
- Faster agent-led exploration paths across unfamiliar code
- Reduced reliance on exhaustive manual file listing in prompts

Recommended Marketplaces
Journey fit
Semantic code search is primarily adopted while building and extending the repo, though it also speeds review and production fixes. agent-tooling is the canonical shelf because Beacon extends how the coding agent discovers symbols and flows across files.
How it compares
Agent tooling marketplace for semantic repo search, not an MCP server catalog entry or a testing skill.
Common Questions / FAQ
Who is Claude Code Beacon Plugin for?
It is for Claude Code users who need embedding-based semantic search to navigate medium-to-large codebases during implementation and fixes.
When should I use Claude Code Beacon Plugin?
Use it when grep and filename search fail to find the right module, especially while building features, reviewing changes, or tracing bugs across services.
How do I add Claude Code Beacon Plugin to my agent?
Add sagarmk/beacon-plugin as a Claude Code marketplace, install the beacon plugin, then complete Beacon setup from its GitHub README before searching in your project.
