Weavatrix Online extension: guarded sync, advisories, malware review, architecture contracts.

Overview

AI-generated overview

A local stdio MCP extension that adds guarded, source-free synchronization of repository graph evidence to Weavatrix Cloud or a compatible endpoint.

What you can do
Weavatrix Online exposes seven MCP tools for endpoint discovery, advisory refresh, dependency vulnerability and malware scanning, architecture-contract retrieval, and controlled synchronization. It analyzes a repository locally, builds a bounded source-free payload, and requires an exact short-lived confirmation token from preview_sync before sync_graph can send anything. Advisory and malware scans run against a local cache and report NOT_CHECKED or PARTIAL when evidence is incomplete.
When to use it
Use it when endpoint status, remotely managed architecture contracts, advisory refresh, or explicit source-free synchronization is part of the workflow. Keep the plain Weavatrix package when the graph must stay entirely local. Installing or starting it does not synchronize anything by itself.
Requirements
Node.js with npx; the package runs as a local stdio process and takes a repository path as its first argument. Network workflows need WEAVATRIX_SYNC_URL and, for authenticated endpoints, the WEAVATRIX_SYNC_TOKEN bearer token. Optional variables include WEAVATRIX_CAPABILITIES_URL, WEAVATRIX_ARCHITECTURE_URL, WEAVATRIX_PRECISION, WEAVATRIX_GRAPH_HOME and WEAVATRIX_ADVISORY_STORE.
Before you install
WEAVATRIX_SYNC_TOKEN is a scoped bearer token and should be kept in the MCP client's runtime secret storage, not in Git, a committed .env, release logs, or checked-in configuration. sync_graph sends an approved payload to a third-party endpoint; review the displayed repository identity, destination, counts, sections, and hash before approving. Source-free does not mean anonymous. Malware findings are static evidence only and never a compromise verdict.

Installation

In SourceWeft

  1. Open Weavatrix Online in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

Weavatrix Online

Take repository intelligence across a network without handing the network your repository.

[npm] [CI] [license] [Node.js]

The explicit network boundary of the Weavatrix ecosystem. Core and Refactor remain separate installs.

Weavatrix Online is the MIT-licensed MCP connector for Weavatrix Cloud and compatible customer-controlled endpoints. It keeps analysis local, produces an inspectable source-free payload, and requires an exact short-lived confirmation before that payload can leave the machine.

The public Online profile exposes 7 MCP tools for endpoint discovery, advisories, malware review, architecture contracts, and controlled synchronization. The local weavatrix-js graph engine is an implementation detail: its tools are not re-exported, so installing Core, Refactor, and Online together does not duplicate their catalogs in an agent's context.

Installing or starting Online does not synchronize anything. preview_sync makes no network request; sync_graph accepts only the still-valid preview for the same repository, destination, payload, and graph.

Choose the right Weavatrix package

ProductInstallBoundary
weavatrixnpm or CargoNative local-first MCP product. Both package managers distribute the same local Weavatrix server and engine.
weavatrix-rustCargoProtocol-independent Rust repository-intelligence engine for library and CLI use; it does not own MCP transport.
weavatrix-refactornpm or CargoNative extension-only transactional refactoring; it uses the Rust graph engine internally.
weavatrix-onlinenpmThis optional network extension: source-free Cloud/self-hosted workflows over an internal local graph runtime.

Online currently uses the JavaScript graph/runtime package internally:

text
weavatrix-online 0.3.4  └─ weavatrix-js 0.3.x (internal; no Core tools re-exported)

It does not proxy the native weavatrix executable, import weavatrix-refactor, or copy either engine. Use weavatrix when the graph must remain entirely local. Use weavatrix-online when endpoint status, remotely managed architecture contracts, advisory refresh, or explicit source-free synchronization is part of the workflow.

Install and run

Plugins for Cursor, Codex, Claude, and Grok

The repository now contains one portable plugin bundle at plugins/weavatrix-online plus native marketplace manifests for all four clients. The plugin starts the pinned npm release and includes an optional, compact skill with one lazily loaded card per Online method.

text
codex plugin marketplace add Weavatrix/weavatrix-online --sparse .agents/plugins plugins/weavatrix-onlinecodex plugin add weavatrix-online@weavatrix-online
claude plugin marketplace add Weavatrix/weavatrix-online --sparse .claude-plugin pluginsclaude plugin install weavatrix-online@weavatrix-online
grok plugin marketplace add Weavatrix/weavatrix-online

Cursor can load the bundle locally from ~/.cursor/plugins/local/weavatrix-online; public marketplace discovery starts after the listing is reviewed and approved.

Direct MCP launch

Run the pinned release without a global install:

powershell
npx -y [email protected] C:\path\to\repository

The command starts a stdio MCP server. The first positional argument is the repository to analyze. An existing graph can be supplied explicitly:

powershell
npx -y [email protected] C:\graphs\repository\graph.json C:\path\to\repository

The npm package is intentionally an executable MCP product; it does not advertise a nonexistent JavaScript library entry point.

Keep bearer tokens in the MCP client's runtime secret storage. Do not put them in Git, a committed .env, release logs, or checked-in MCP configuration.

The seven Online tools

ToolNetworkEvidence and effect
online_statusYesDiscovers endpoint capabilities, payload versions, limits, and auth mode without repository evidence.
refresh_advisoriesYesInventories exact dependency coordinates, queries OSV, validates returned records, and atomically refreshes the local cache.
scan_dependency_vulnerabilitiesNoMatches the current inventory against that cache. Missing, stale, partial, or mismatched coverage remains NOT_CHECKED or PARTIAL.
scan_dependency_malwareNoPerforms bounded static review of installed dependency files. Findings require review and are never a compromise verdict.
pull_architecture_contractYesFetches the owner-approved target for the active opaque repository ID, validates it, and updates the local graph cache.
preview_syncNoSerializes the exact allowlisted payload, hashes it, and issues a five-minute confirmation token.
sync_graphYesSends only the payload approved by preview_sync; dry_run:false and the matching token are mandatory.

Install Weavatrix Core for read-only repository intelligence and Weavatrix Refactor for guarded source changes. Their methods remain in their owning products.

Typical workflows

Check endpoint compatibility before doing any repository work:

json
{"name":"online_status","arguments":{"timeout_ms":10000}}

Refresh advisory evidence, then evaluate it locally:

json
{"name":"refresh_advisories","arguments":{"timeout_ms":20000}}{"name":"scan_dependency_vulnerabilities","arguments":{"max_age_days":30}}

Review the exact upload without sending it:

json
{"name":"preview_sync","arguments":{"payload_version":3}}

After a human or trusted controller approves the displayed destination, section summary, counts, size, and body hash, use the returned token:

json
{  "name": "sync_graph",  "arguments": {    "payload_version": 3,    "dry_run": false,    "confirm_token": "token-returned-by-preview_sync",    "timeout_ms": 30000  }}

Changing the graph, repository, destination, payload, or expiry state invalidates that approval. A rejected or unavailable endpoint leaves the graph local.

Network and consent boundary

text
local repository      │      ▼local graph + derived evidence      │      ▼preview_sync ── inspect destination, sections, counts, size, and SHA-256      │      ▼explicit approval      │      ▼sync_graph ── capability negotiation ── approved endpoint

The connector enforces:

  • HTTPS for every non-loopback destination;
  • loopback-only HTTP for local development;
  • no credentials embedded in URLs;
  • endpoint capability negotiation before upload;
  • a bounded versioned payload allowlist;
  • exact preview hashing and a short-lived confirmation token;
  • honest NOT_CHECKED and PARTIAL states when evidence is incomplete.

The sync payload contains bounded graph topology and selected derived evidence. It excludes source bodies, snippets, absolute host paths, environment values, credentials, Git remotes, and fields outside the wire allowlist. “Source-free” does not mean anonymous: review the displayed repository identity, destination, counts, sections, and hash before approval.

Configuration

VariableRequiredMeaning
WEAVATRIX_SYNC_URLFor Online network workflowsCloud or compatible self-hosted sync endpoint.
WEAVATRIX_SYNC_TOKENFor Cloud/authenticated endpointsScoped bearer token sent only to the approved endpoint.
WEAVATRIX_CAPABILITIES_URLNoExplicit capability document; otherwise /api/v1/capabilities with legacy /api/health fallback.
WEAVATRIX_ARCHITECTURE_URLNoExplicit owner-approved architecture-contract endpoint.
WEAVATRIX_PRECISIONNoLocal semantic precision: lsp (default) or off.
WEAVATRIX_GRAPH_HOMENoOverride local graph/cache storage.
WEAVATRIX_ADVISORY_STORENoOverride the local advisory-cache file.

Compatible endpoints must implement the versioned capability and sync contracts. Capability discovery itself sends no repository evidence.

Security evidence without false certainty

Advisory refresh covers pinned npm, PyPI, Go, Maven/Gradle, and crates.io coordinates found in bounded repository manifests. A clean zero is allowed only when the current inventory matches a complete, current Online cache.

Malware review is static and bounded. It can identify evidence such as download-and-execute lifecycle scripts, reverse-shell patterns, decoded execution, miner indicators, credential-file reads, or suspicious exfiltration endpoints. It cannot prove execution, provenance, credential exposure, safety, or compromise.

Architecture contracts are validated locally before becoming active.

Report vulnerabilities privately through GitHub Security Advisories.

Architecture

The connector is a strict modular ports-and-adapters system:

text
policy  └─ discovery adapters       └─ security cache and evidence services            └─ Online actions                 └─ MCP composition and executable
  • policy: destination validation, version matching, inventory identities, and malware evidence rules;
  • discovery: bounded manifest and installed-package adapters;
  • security: atomic advisory state, cached matching, scanning, and reporting;
  • online-actions: capability, contract, advisory, preview, and sync use cases;
  • composition: extension registration, launcher, and stdio executable.

The checked-in architecture contract enforces zero runtime cycles, production files at or below 300 physical lines, and functions at or below 100 physical lines, with no exceptions and no violation baseline.

Development and release proof

powershell
npm ci --ignore-scriptsnpm testnpm run verify:releasenpm auditnpm pack --dry-run --json

The release gate verifies package identity, dependency ranges, exact installed versions, MCP Registry metadata, checked-in release notes, MIT licensing, the published file allowlist, and tag/version agreement. CI repeats the tests, security audit, and package dry-run on Node.js 24.
