Context7 vs srclight

Context7: Context7 is an MCP server that injects up-to-date, version-specific library documentation directly into LLM prompts. Add "use context7" to any coding prompt and it fetches current docs for the library you're working with, eliminating hallucinated APIs and outdated code examples. Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible editor.; srclight: Srclight builds a rich, searchable index of your codebase that AI coding agents can query instantly, replacing inefficient grep/glob calls with precise, structured lookups. It provides comprehensive code intelligence, including symbol search, relationship graphs, and semantic search, all while operating fully local and private.

TL;DR

Context7 logo
Context7Code Assistant · ★ 63.5k
When to choose:
  • You use Cursor, Claude Code or another coding agent with fast-moving public libraries and want current, version-specific docs and examples.
  • You want the least setup: `npx ctx7 setup` signs you in and configures the skill or MCP server for your agents.
  • You want to work with or without MCP: the CLI plus skill mode fetches docs without an MCP server.
When to skip:
  • You need docs for internal or private libraries: a self-hosted index fits better.
  • Your data policy rules out sending queries to an external service: requests go to Upstash's hosted backend.
  • You need a fully open-source stack: only the MCP server is open source; the API backend, parser and crawler are private.

Use Cases

Context7 logoContext7
↳Preventing LLMs from hallucinating deprecated or non-existent API methods
↳Getting accurate code examples for the exact library version in use
↳Keeping AI coding assistants up-to-date across fast-moving frameworks
srclight logosrclight
↳AI agents can instantly get codebase overviews and find callers/callees, drastically reducing orientation time.
↳Developers can perform semantic searches with natural language queries like "find code that handles authentication" to locate relevant code by meaning.
↳Before committing changes, analyze the "blast radius" to see what other parts of the codebase will be affected, preventing unintended breaks.
↳Integrate with MCP clients like Claude Code or Cursor to enhance AI's ability to understand, navigate, and modify complex codebases.
↳Index and search across multiple projects simultaneously, providing a unified code intelligence view for large codebases or monorepos.
