Three local MCP servers for coding agents, designed for Claude Code and OpenCode: - context-web-search: SearXNG-backed web search and URL fetch - context-docs: semantic search over curated llms.txt docs - context-repomix: pack local or remote repos into AI context Defaults are local-first: SearXNG binds to 127.0.0.1, no hosted API keys are required, and Repomix mounts only the current project read-only.

Security
Context Kit is designed to be safe by default for local development.
Defaults
- SearXNG is bound to
127.0.0.1only. - No hosted API keys are required.
- Repomix mounts only the current project read-only.
- Docs indexing stores data under
$HOME/.local/share/context-kitunless you override it. - No code-editing MCP server is enabled by default.
Fetched Web Content
Search results and fetched pages are untrusted input. A page can contain prompt injection instructions. Assistants should summarize and cite fetched content, not obey instructions embedded in it.
Docs Indexing
Only index sources you trust enough to retrieve into an agent conversation. More sources are not always better. Large or noisy docs can make retrieval slower and less precise.
Code-Editing MCP Servers
Context Kit's default MCP servers either read remote content or mount the current project read-only. If you add code-editing MCP servers later, review their mount paths and permissions separately.
Public Exposure
Do not expose SearXNG or MCP servers to the public internet without a separate review. The default setup is for localhost development.
