| mif-frontmatter | library | Markdown frontmatter <-> JSON-LD lossless round-trip |
| mif-embed | library | Local sentence-embedding inference |
| mif-store | library | SQLite vector store for document embeddings |
| mif-cli | binary | Command-line interface (validate, ontology resolve, ingest, search, find-similar, corpus-stats) |
| mif-mcp | binary | MCP server exposing the same six operations as tools |
Installation
cargo add mif-core mif-schema mif-ontology mif-problem mif-frontmatter mif-embed mif-store # libraries
cargo install mif-cli mif-mcp # binaries
Quick start
mif-cli validate document.json
mif-cli ontology resolve grazing-plan --ontologies-dir ./ontologies
mif-cli ingest document.md --db-path .mif/vectors.db
let document: serde_json::Value = serde_json::from_str(&contents)?;
mif_schema::validate_document(&document)?;
Development
just is the local task runner. Run just to list all recipes.
Run lefthook install once after cloning to set up local git hooks mirroring
CI (fmt/clippy/test on commit/push).
just check # Full CI check (fmt + clippy + test + doc + deny)
just build # Debug build (workspace)
just test # All tests
Raw cargo equivalents
cargo build --workspace
cargo test --workspace --all-features
cargo clippy --workspace --all-targets --all-features -- -D warnings
cargo fmt --all -- --check
cargo doc --workspace --no-deps --all-features

CI/CD and releases
CI (pipeline.yml, quality-gates.yml) runs formatting, lint, tests, docs,
supply-chain checks, and the org's SAST/SCA/Scorecard/Trivy gates on every
push and PR. Releases are tag-triggered (release.yml, publish.yml,
package-homebrew.yml) and produce SLSA-attested, multi-platform binaries
for both mif-cli and mif-mcp, plus crates.io publication via Trusted
Publishing. See docs/runbooks/RELEASING.md
for the full procedure and SECURITY.md
for artifact verification commands.
See CLAUDE.md for full development conventions (lint configuration, error
handling, testing).
