Sixteen mutating routes now refuse a caller who cannot present the token the server started with; queries stay open, because a question is not a write. The environment variable is ELY_EYE_AUTH_TOKEN, following the repo's env_prefix convention — the shorter name I reached for first returned 403 where the smoke expected 401, and the server printed the reason. Words from a stranger are quarantined on the way in: an HTTP upload is third_party by definition, and a sentence carrying an instruction-shaped phrase is quarantined whoever wrote it. A quarantined atom stays findable and stays out of the compiled context until a second, live, unquarantined source agrees with its rarest words. Corroboration is computed at read time because it is a property of the corpus now, not of the moment a memory was written; it is term-level, and the docstring says so. forget now erases the source row and the compiled contexts beside the atoms, so a forgotten memory leaves nothing that can still speak. The semantic cache key carries a store revision, which fixes a real staleness: a context compiled before new evidence arrived kept its old quarantine decision forever. bench.audit --product still pointed at evals.py, which the p1-6 split moved into backend/src/ely_eye/proofs/. It failed fast, but the anti-self-justification rule had quietly stopped auditing the product; it now walks the package, and a test pins that the package exists and holds no re-roll. Gates: pytest 306 passed; ruff clean; mypy cold cache 24 errors in 9 files, the recorded baseline, net zero; pyright 0 errors on the 23 backend files and the 2 bench files; go build/vet/test and gofmt clean; npm run build 221.39 kB with eslint exit 0; bench/filesize_check clean; bench.audit --product clean over 31 harness files; scripts/mcp_write_smoke.sh PASS with the gate live across two servers and the MCP child.
Ely-Eye MCP
Ely-Eye MCP exposes a local Context Cartridge memory store as a stdio Model Context Protocol server for coding agents such as Codex and Claude Code.
The server is local-first and read-only against <ely-eye-home>/data/ely_eye.sqlite. It reads Evidence Atoms, cartridge manifests, Memory DNA, proof-suite artifacts, HashHop proofs, and compiled evidence packs. The production database is never modified.
It can be deployed for any .ely_eye store. Identity is anchored on the database file, not on the Ely-Eye repository layout, so the server walks up from the working directory to find .ely_eye/data/ely_eye.sqlite, or takes an explicit --ely-eye-home.
One-command setup
The installer downloads a checksum-verified prebuilt binary for the platform when a tagged release is available, otherwise it builds from source with Go from a repository checkout. Either way it installs the binary into <ely-eye-home>/bin and registers the server with Codex and Claude Code. No Docker.
Windows:
powershell -ExecutionPolicy Bypass -File .\ely-eye-mcp\install.ps1 -Client both
Linux and macOS:
bash ./ely-eye-mcp/install.sh --client both
Force a source build (requires Go 1.25 or newer):
bash ./ely-eye-mcp/install.sh --method source
Codex registration uses codex mcp add. Claude Code project registration writes .mcp.json at the project root; --scope user registers through the Claude CLI instead.
Manual run
From inside a project that owns an .ely_eye store:
go run ./cmd/ely-eye-mcp server
Or point at an explicit store:
go run ./cmd/ely-eye-mcp server --ely-eye-home /path/to/.ely_eye
Tools
ely_eye_status returns atom, source, cartridge, token, and cache-layer counts.
list_cartridges lists local Context Cartridges with manifest JSON and Memory DNA.
get_cartridge reads one cartridge plus artifact metadata, memory capsule index, and asset report.
search_atoms queries the local SQLite FTS index and returns ranked Evidence Atoms.
fetch_atom reads one Evidence Atom by exact id.
compile_context compiles a question into a local evidence pack with the same profile names used by the app (live_demo, extreme_context, library_100m, research_theater).
list_proof_suites lists PRD proof suites under <ely-eye-home>/data/eval_proofs.
list_hashhop_proofs aggregates HashHop and Visual HashHop long-context addressing proofs by kind, hop count, and token budget, with pass counts and example proofs. Proofs are deduplicated by content-derived id.
get_proof_suite reads one PRD proof suite by id, including all checks and a summary of its HashHop proofs.
Resources
ely-eye://project/prd, ely-eye://project/readme, and ely-eye://project/mcp-research expose PRD.md, the project README, and these research notes when those files are present next to the store.
Releases
Pushing a mcp-v* tag runs .github/workflows/mcp-release.yml, which cross-compiles the pure-Go server (CGO disabled) for Linux, macOS, and Windows on amd64 and arm64, then publishes the archives with a SHA256SUMS manifest to a GitHub Release. The installers consume those assets.
Security posture
The server opens SQLite read-only with mode=ro and PRAGMA query_only(1), and uses busy_timeout so reads tolerate concurrent writes by the Ely-Eye app. Tools expose structured outputs and return tool-level errors for invalid inputs so agents self-correct through normal tool calls. Proof ids are validated as single path elements before any filesystem read. The server uses stdio transport for local clients and takes credentials only from the local environment.
