commit c905cf86c8db6a7e08d2e980f2395bb669576a3a Author: Ajay Krishnan Date: Thu May 21 08:43:38 2026 -0700 Initial public release 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. diff --git a/.env.example b/.env.example new file mode 100644 index 0000000..11f73b7 --- /dev/null +++ b/.env.example @@ -0,0 +1,23 @@ +# Copy to .env to override local defaults. + +# Where Context Kit stores docs indexes and model caches. +# Default: $HOME/.local/share/context-kit +# CONTEXT_KIT_DATA_DIR=/path/to/context-kit-data + +# Docker Compose project name.
