Project Context Router

A local-first CLI and Model Context Protocol server that gives coding agents structured project memory, task contracts, compact context packs, backlog workflows, and verification evidence.

The router keeps durable knowledge in reviewable Markdown and YAML inside the consumer repository. A disposable SQLite index makes retrieval fast without turning an external service into the source of truth.

Status: active development. The current package is vincenzo-mcp-context@0.4.0, requires Node.js 22.13 or newer, and is distributed from source or a versioned tarball. It is not currently published to an npm registry.

Why use it?

• Keep project memory versioned beside the code that it describes.

• Give agents a focused context pack instead of an unbounded repository dump.

• Validate and confirm a Task Contract before implementation begins.

• Search existing capabilities before adding duplicate code.

• Track backlog state, dependencies, decisions, and verification evidence.

• Expose the same workflow through a human-friendly CLI and MCP tools.

• Keep generated drafts and indexes out of version control and package artifacts.

Quick start

Install directly from GitHub in the repository that should own the project context:

npm install --save-dev --save-exact github:ukolov-dev/mcp-project-context-router
npx project-context init --name "Example Project" --module app:src
npx project-context index
npx project-context doctor --json

init is non-destructive: it does not overwrite an existing configuration. Review .project-context/project.yaml after generation and replace the example modules, source globs, playbooks, and verification commands with real project values.

A typical agent workflow then looks like this:

npx project-context validate-task "Add CSV export" --mode feature
npx project-context pack "Add CSV export" --workflow standard --explain
npx project-context reuse-scan "CSV export"
npx project-context verify-task "CSV export"

Run npx project-context --help for the complete CLI surface.

Connect your coding agent

The package includes client-specific setup guides and copy-ready configuration templates:

All three configurations start the same local stdio MCP server from the consumer repository. They contain no credentials or workstation-specific absolute paths. Codex uses .codex/config.toml; OpenCode uses opencode.json at the repository root. The two OpenCode schemas are intentionally separate because stable and V2 currently use different MCP nesting and enablement fields.

The server supports scoped tool profiles:

core is the default. The legacy PPM_CONTEXT_TOOL_PROFILE variable remains supported for compatibility.

How data is laid out

.project-context/
├── project.yaml       # routing, modules, commands, and project identity
├── active/            # reviewed, durable project records
├── drafts/            # reviewable generated proposals (ignored)
├── indexes/           # rebuildable SQLite/cache data (ignored)
└── templates/         # Task Contract and Verification Record templates

Project data belongs to the consumer repository, not to this package. The configuration routes queries to modules and playbooks; the index adds fast retrieval; the CLI and MCP server apply the same workflow and repository-boundary checks.

Safety model

• Repository-boundary and symlink-escape checks reject paths outside the project.

• Secret-like values are redacted from generated excerpts.

• Credentials are read from environment variables or supported native credential stores and are never written into exported project context.

• Indexes, drafts, trash, build outputs, and local environment files are ignored.

• The npm package allowlist excludes source-project records, credentials, source TypeScript, tests, and generated SQLite databases.

• Network integrations such as Confluence and Context Hub are optional and require explicit project configuration and credentials.

Develop locally

git clone https://github.com/ukolov-dev/mcp-project-context-router.git
cd mcp-project-context-router
npm ci
npm run build
npm test
npm run package:check
node bin/project-context doctor --json

To exercise the installable artifact locally:

mkdir -p artifacts
npm pack --pack-destination ./artifacts

The tarball contains compiled runtime code, launchers, hooks, credential helper scripts, installation guides, consumer templates, and this README. It excludes .project-context, .codex, tests, source TypeScript, generated indexes, and node_modules.
