Five field reports in the 24 hours after v0.10.0 all pointed at the same thing: gates that were right in principle refused real, ordinary setups, and then failed to say why. Per the consolidated strictness decision, each gate keeps the protection that matters and drops the part that was refusing legitimate users — and every refusal now names what it refused and how to proceed. **Daemon image gate: npx and every ephemeral install path (#1539, #1383).** The admission check treated "the peer's image hashes differently" and "the peer's image cannot be examined at all" as one failure. The second is what `npx codebase-memory-mcp` always produces (ephemeral cache path, unfingerprintable), so every npx-invoked client was rejected — and, because the client never reported it, agents saw a transport that closed mid-handshake with zero bytes on stdout. Reported by @wassolles with the admission path already read and the fix space mapped. An unverifiable image is now admitted: the rendezvous HELLO immediately above it has already proven semantic version, build fingerprint, and protocol/store/ feature ABI, and the image check was trading that real proof for an unavailable one. It logs daemon.client_image_unverifiable_admitted so the weaker check is never invisible. A fingerprint MISMATCH — the tamper case the gate exists for — still rejects hard. Separate test seams keep the two modes testable apart. **Client bootstrap failures are no longer silent (#1539).** An MCP client that cannot reach the daemon now emits a JSON-RPC error on stdout naming the reason, plus the same text on stderr. Previously the reason sat in bootstrap_result.message and the process exited having written nothing at all. **POSIX activation: group-writable ancestors (#1535, discussion #1526).** activation_directory_secure required no group or other write bit on the install directory AND every ancestor. WSL2 ships ~ and ~/.local at 0775, as do several distro skeletons and any site using a shared primary group, so install.sh failed for a large fraction of Linux users — reporting a policy refusal as "activation transaction I/O failed", which sent reporters after disk errors and filesystem types. Root-caused by @AmirF194 in a clean ubuntu container; @shochdoerfer and @iandol confirmed independently. World-writable ancestors are still refused (any local user could swap a path component mid-transaction). Group-writable ancestors are now warned about and admitted. The LEAF directory stays strictly owner-private — that is where the binary is published, and group write there would let another account replace the executable between validation and exec. Refusals now name the directory, its mode, and which rule refused. **The obsolete ui/standard chooser (#1538, from discussion #1526).** v0.10.0 consolidated to one archive per platform with the UI always embedded, but `update` still offered a variant choice: "ui" could only 404, and "standard" quietly WAS the UI build. Reported by @iandol upgrading 0.9.0 -> 0.10.0. The chooser, its --standard/--ui flags, and the ui- URL plumbing are removed, along with the CBM_VARIANT=ui remnant in the npm installer. Already-released 0.9.x binaries cannot be fixed retroactively, so the release workflow now publishes byte-identical ui-*-named alias assets — their updaters work again with no user action. The aliases are uploaded AFTER the VirusTotal gate: they are the same bytes as archives it already cleared, and uploading them earlier would duplicate every object in the scan set and the provenance manifest. **macOS install noise and attribution (#1537).** install.sh silenced the "No such xattr: com.apple.quarantine" line, which is what happens when a curl-downloaded archive carries no quarantine attribute — harmless, and it became the title of a bug report about an unrelated failure. The session-stop refusal now points at `daemon status` to list the client processes actually holding the daemon, instead of asserting sessions exist and leaving the reader to guess. Reported by @listepo. **Riders.** hatchling is pinned in pkg/pypi (an unpinned backend resolved fresh inside `python -m build` is what emitted Metadata-Version 2.5 and broke the v0.10.1 publish); SECURITY.md's supported-versions table moves to 0.10.x. Tests: separate seams for unverifiable vs mismatched peer images with a test per outcome; activation refusal must name directory + mode + rule; a group-writable ancestor must stage successfully. The update tests drop the flag that no longer exists. Verified against each reporter's environment shape. **Open security alerts (all three, OSSF Scorecard).** - HIGH, binary artifact: an 8.8 MB compiled Go ELF wrapper had been committed at pkg/go/codebase-memory-mcp by accident. Removed, and both it and its .exe sibling are gitignored so `go build` in that directory cannot repeat it. - HIGH, GHSA-2v37-7h3g-55p8: nanoid < 3.3.17 loops forever when a custom generator is called with size 0. It reaches us transitively (postcss -> vite), so it is pinned through the existing graph-ui overrides block rather than promoted to a direct dependency; the lockfile resolves 3.3.18. - MEDIUM, unpinned pip command: the publish step installed build/twine by version only, leaving the whole transitive graph resolved at run time. pkg/pypi/requirements-publish.txt now hash-pins the complete toolchain (316 hashes), generated on a linux/amd64 python:3.12 image so the wheels match what ubuntu-latest resolves, and the step runs pip with --require-hashes. Verified by installing from it in that same image. Signed-off-by: Martin Vogel <martin.vogel.tech@gmail.com>
codebase-memory-mcp
The fastest and most efficient code intelligence engine for AI coding agents. Full-indexes an average repository in milliseconds, the Linux kernel (28M LOC, 75K files) in 3 minutes. Answers structural queries in under 1ms. This npm wrapper downloads, verifies, and caches the selected native runtime set: the executable, its authenticated integration asset, and—when requested—the content-addressed UI pack.
High-quality parsing through tree-sitter AST analysis across 159 languages — producing a persistent knowledge graph of functions, classes, call chains, HTTP routes, and cross-service links. 14 MCP tools. No hosted service or API key; this package requires Node.js to manage and launch the cached native runtime set. Plug and play across 43 automatic/conditional client surfaces.
Installation
npm install -g codebase-memory-mcp
The runtime set for your platform is downloaded automatically at install time. There is one composition per platform and the graph UI is always included — the former CBM_VARIANT=ui opt-in is obsolete.
Then configure your coding agents:
codebase-memory-mcp install
Restart your agent. Say "Index this project" — done.
Why codebase-memory-mcp
- Extreme indexing speed — Linux kernel (28M LOC, 75K files) in 3 minutes. RAM-first pipeline with LZ4 compression and in-memory SQLite.
- Plug and play — verified native runtime sets for macOS (arm64/amd64), Linux (arm64/amd64), and Windows (arm64/amd64). No Docker or API keys; Node.js owns package download, cache repair, and launch.
- 159 languages — vendored tree-sitter grammars compiled into the binary. Nothing to install, nothing that breaks.
- 120x fewer tokens — 5 structural queries: ~3,400 tokens vs ~412,000 via file-by-file search.
- 43 supported automatic/conditional client surfaces —
installconfigures the appropriate MCP, durable-context, and documented hook surfaces without widening client permissions. - Detected automatically (37) — Claude Code, Codex CLI, Gemini CLI, Zed, OpenCode, Antigravity, Aider, KiloCode, VS Code, Cursor, Windsurf, Augment / Auggie, OpenClaw, Kiro, Junie, Hermes, OpenHands, Cline, Warp, Qwen Code, GitHub Copilot CLI, Factory Droid, Crush, Goose, Mistral Vibe, Qoder CLI, Kimi Code CLI, GitLab Duo CLI, Rovo Dev CLI, Amp, Devin CLI / Local, Tabnine, Amazon Q Developer IDE, CodeBuddy Code CLI, IBM Bob Shell, Pochi, and Pi.
- Conditional or explicit (6) — Continue / cn, Visual Studio, TRAE, Roo Code, IBM Bob IDE, and Sourcegraph Cody. Bob IDE is touched only when
~/.bob/mcp.jsonalready exists. - New documented adapters — CodeBuddy uses
~/.codebuddy/.mcp.jsonwhile preserving active older files; Bob Shell uses~/.bob/mcp_settings.json; Pochi uses themcpsection in~/.pochi/config.jsonc; Amazon Q Developer IDE defaults to~/.aws/amazonq/default.jsonwhile preserving either documented alternative. - Lifecycle hooks stay conservative — Kimi uses
UserPromptSubmit; on macOS/Linux, GitLab Duo gets a fail-open userSessionStart, while Devin getsUserPromptSubmit,PostCompaction, and a deduplicatedSessionStartwhen Claude does not already provide it. Qoder, GitLab Duo, Devin, and Factory hooks are withheld on Windows without a documented shell/executor contract. Cline's auto-activating file hooks are withheld because their context output is not reliably consumed, CodeBuddy beta hooks are not auto-installed, and Cursor context hooks remain withheld. - Subagent access is explicit — Claude, Gemini, Kiro, Qwen, CodeBuddy, KiloCode, Mistral Vibe, Qoder, Junie, and Factory get documented graph profiles with the narrowest tool/server filters their schemas support. KiloCode and Vibe enumerate read-only query tools rather than using server wildcards. Cursor, Rovo, Pochi, and Cline use explicit parent handoff where child MCP is unavailable or unsafe; IBM Bob receives no invented hook or agent.
- Manual, UI, cloud, or repository-managed (not counted) — Qodo, Warp MCP, JetBrains AI/ACP, GitHub Copilot coding agent, Jules, CodeRabbit, Replit, BLACKBOX AI, Plandex, and SWE-agent. Warp is counted above for its detected skill installation; its MCP connection remains manual.
- 14 MCP tools — search, trace, architecture, impact analysis, Cypher queries, dead code detection, cross-service HTTP linking, ADR management, and more.
