Weavatrix Online extension: guarded sync, advisories, malware review, architecture contracts.
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.
Installation
In SourceWeft
- Open Weavatrix Online in the dashboard and add it to a workspace.
- 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
Online currently uses the JavaScript graph/runtime package internally:
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.
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:
The command starts a stdio MCP server. The first positional argument is the repository to analyze. An existing graph can be supplied explicitly:
The npm package is intentionally an executable MCP product; it does not advertise a nonexistent JavaScript library entry point.
Codex
Claude Desktop
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
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:
Refresh advisory evidence, then evaluate it locally:
Review the exact upload without sending it:
After a human or trusted controller approves the displayed destination, section summary, counts, size, and body hash, use the returned token:
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
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_CHECKEDandPARTIALstates 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
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:
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
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.
License
MIT. Weavatrix Online and its internal weavatrix-js runtime are
independently versioned MIT-licensed packages.
