ITHZ MCP

MCP36.4 Integration and Pregame Constitution

The MCP36.4 integration pack includes the read-evidence compatibility fix and the Pregame project constitution. Existing root downloads and registry metadata below remain on their previously published versions; this update is not a new binary or PyPI release.

Local-first deterministic project memory for AI coding agents and MCP-compatible development workflows.

ITHZ MCP stores durable agent work memory in project-owned files: context packs, decisions, gates, risks, reviewer notes, scoped claims and explicit checkpoints. Git remains the code history and transport; ITHZ MCP keeps the operational memory that helps agents resume work without depending only on hidden chat history or repeated full-repo scans.

Install From PyPI

python -m pip install ithz-mcp
python -m ithz_mcp version

Minimal stdio MCP configuration:

{
  "mcpServers": {
    "ithz_mcp": {
      "command": "python",
      "args": [
        "-m",
        "ithz_mcp",
        "mcp-server",
        "--project",
        "/path/to/project",
        "--mode",
        "read-only",
        "--protocol",
        "direct",
        "--storage-profile",
        "native-archive"
      ]
    }
  }
}

Use a write-enabled profile only when your host and workflow explicitly allow the agent to append sanitized task checkpoints into project.ithz.

What It Is

ITHZ MCP is a local project-memory layer for AI-assisted development. It is designed for agents and developers who want deterministic, auditable handoff state next to the project:

• context packs for onboarding an agent to a repo or task

• durable decisions, gates, risks and next steps

• reviewer notes and scoped claim ledgers

• end-of-task checkpoints for future agents

• local-first operation through project-owned memory files

• MCP stdio integration for compatible coding-agent hosts

What It Is Not

ITHZ MCP does not replace Git, a production database, cloud sync, a source-code backup, a vector database, or every retrieval system. It complements these tools by keeping durable project memory explicit and inspectable.

Agent Bootstrap

For agent-assisted installation into another project:

1. Copy ithz_mcp.md or install_ithz.md into the target project.

2. Ask the local coding agent to read that file and install ITHZ MCP.

3. The agent should preserve an existing project.ithz if present, configure local MCP/Git support, and report exactly what changed.

Platform Notes

macOS Intel Native Runtime

ithz-mcp-macos.zip installs the Python stdio MCP layer. Native project.ithz storage on Mac Intel additionally needs ithz-native, which can be built from ithz-native-macos-intel-build-kit.zip:

unzip ithz-native-macos-intel-build-kit.zip
cd ithz-native-macos-intel-build-kit
chmod +x native_ithz/macos_native/build_macos_native_package.sh
native_ithz/macos_native/build_macos_native_package.sh --arch x86_64

Then install the generated native package:

cd native_ithz/dist/macos_native/ithz-native-preview-v0.1-alpha-rc2-macos-x86_64
./smoke_test.sh
./install_macos_native.sh
export ITHZ_NATIVE_EXE="$HOME/.local/share/ithz-mcp/native/ithz-native"

Ubuntu/Linux

The Ubuntu package includes install_ithz.md, Linux host installers, user-local wrapper scripts, a Linux native source build kit and extraction-backed fallback commands:

tar -xzf ithz-mcp-ubuntu.tar.gz
cd ithz-mcp-ubuntu
./install.sh
./install_linux_native.sh
ithz-mcp version
ithz-native-resolve

Native Linux project.ithz support uses the bundled build kit and dynamically loads the system zlib runtime (libz.so.1 / libz.so).

Status

ITHZ MCP is currently free during alpha preview. Public package metadata is published on PyPI and in the official MCP Registry.
