v0.2.3

v0.2.3 launch notes

HeliosDB CodeKB MCP v0.2.3 focuses on agent installation and token-saving usage:

• ready-to-use Claude Code and Codex config templates
• compact helios(action, args) MCP wrapper mode
• wrapper cache support for repeated calls
• docs/source retrieval workflows for repo and portfolio KBs
• reproducible examples for code+docs KB setup

Install:

cargo install heliosdb-codekb-mcp

Serve:

heliosdb-codekb-mcp serve --source . --mega-tool --wrapper-cache-size 128

v0.2.1 — README install rewrite (Claude Code + CODEX)

[0.2.1] — 2026-05-27

Documentation-only patch on top of 0.2.0. No code changes.

Changed

• README.md rewritten to lead with install instructions for Claude
  Code + OpenAI CODEX (the two MCP-aware coding agents this plugin
  primarily targets), each with a concrete .mcp.json /
  ~/.codex/config.toml snippet plus a one-shot copy/paste invocation.
• Removed the broken curl … releases/download/v0.2.0/… instruction.
  The v0.2.0 release was crates.io-only — no GitHub release artifact
  existed for that tag, so the documented URL returned HTTP 404.
  Pre-built Linux x86_64 binary still ships at the v0.1.0 GH release;
  documented as a fallback with the honest caveat that it's stale vs
  the published crate.
• Install section reordered: cargo install heliosdb-codekb-mcp is
  now the only first-class recommendation. Pre-built binary is
  demoted to "alternative" with the version-staleness warning.

v0.1.0

Platform support

Platform	Status
Linux x86_64	✅ Released — binary attached below
macOS x86_64 (Intel)	Planned — release TBD (GitHub Actions Intel-macOS runners are scarce; tracking)
Linux aarch64	Planned — pending rocksdb cross-compilation work
macOS aarch64 (Apple Silicon)	Planned — pending rocksdb cross-compilation work

If you need a binary for an unsupported platform now, build from source: cargo build --release --features native-binary-docs.

What's in v0.1.0

A single-binary MCP server that indexes a code+docs corpus and exposes 11 LSP-shaped + Graph-RAG tools to Claude Code, Codex, Cursor, Continue, and Aider over stdio or HTTP — no ports, no auth dance, all local.

Tool surface (inherited from embedded heliosdb-nano v3.22.2):

• 10 LSP-shaped: helios_lsp_definition, helios_lsp_references, helios_lsp_hover, helios_lsp_document_symbols, helios_lsp_call_hierarchy, helios_lsp_rename_preview, helios_lsp_rename_apply, helios_lsp_body_diff, helios_lsp_references_diff, helios_ast_diff
• 1 Graph-RAG: helios_graphrag_search (BM25 + optional vector rerank + N-hop graph expansion)

KB-location modes: co-located (<source>/.helios-kb), global ($XDG_DATA_HOME/helios-kb/<slug>), hybrid (explicit --kb).

Ingest tiers: fast (BM25 + hop-distance, ~26 s on the 666-file pilot), --with-embeddings (adds in-process FastEmbedder, ~3 m 15 s), --background-quality (26 s parent + detached child).

See the README for quickstart and .mcp.json wire-up.
