Gives you read and write access to QuickBooks Online's accounting data through the MCP protocol. You can create and query invoices, manage bills, work with customers and vendors, handle employee records, and interact with the chart of accounts. Part of Mindstone's 35-connector monorepo, which means it ships with the same host-orchestrated OAuth patterns and security hardening (pinned dependencies, OIDC provenance, seven-day release cool-down) as their Google Workspace and HubSpot servers. Look for the QB_ALLOW_PROD_WRITES environment flag if you need mutation permissions outside sandbox mode. Reach for this when you're building accounting workflows or need an LLM to pull financial data without opening the QuickBooks UI.

Each server builds independently:
cd connectors/<name>
npm install
npm run build
Or run directly via npx (once published):
npx -y @mindstone/mcp-server-zendesk
Moving from
@mindstone-engineering/? Every server has been republished under the shorter@mindstone/npm scope. The legacy@mindstone-engineering/mcp-server-*packages still install but are marked deprecated. See MIGRATION.md for the consumer one-liner and the deprecation timeline.
See each server's README for configuration and host setup instructions. Some connectors require additional environment variables to opt into specific behaviour (e.g. QB_ALLOW_PROD_WRITES for QuickBooks production writes, MCP_WORKSPACE_PATH for sandboxed file reads, BROWSER_AUTOMATION_ALLOW_EVAL for browser-automation script eval) — see the per-connector READMEs for the full list.
This monorepo follows a defence-in-depth posture for tool-call hosts. Highlights include:
permissions: block. Publish is split into a build job (does the install/test/pack with no publish credentials) and a publish job (downloads the packed tarball, runs only npm publish --ignore-scripts --provenance under OIDC trusted publishing, gated by the npm-publish environment). The publish job invokes NO third-party JS — tsc, vitest, lifecycle scripts, etc. all run upstream, away from id-token: write. See docs/security/AUDIT_FOX-3319_tanstack_supply_chain.md for the supply-chain threat model and docs/security/BRANCH_PROTECTION.md for required GitHub settings..npmrc sets min-release-age=7 (days), so CI refuses to install dependency versions published in the last week. This blocks the "same-day malicious re-publish" path that ships post-npm audit-clean PRs into a release tag..github/workflows/release.yml) under the @mindstone/ npm scope via Trusted Publishing OIDC — no long-lived npm token exists anywhere — with --provenance Sigstore attestations consumers can verify via npm audit signatures. Every publishable release commit must carry a Release-Gate trailer pointing at its pre-release security review, and every publish posts an alert; the full gate chain is in docs/PUBLISH_APPROVAL_PROCESS.md. (Only a brand-new connector's first publish is manual and WebAuthn-gated; those tarballs carry no provenance attestation but remain shasum-verifiable — check out the release commit and run npm pack; see MIGRATION.md.).github/workflows/scorecard.yml. The report is generated by a third party from the source tree, so every claim above (action pinning, branch protection, token usage, dependency hygiene) is independently checked rather than just asserted here. The current score is shown by the badge at the top of this README.These connectors are published as plain npm packages. The strongest single thing you can do to protect yourself from a future supply-chain compromise of any npm package (these or otherwise) is to use a client that does not run lifecycle scripts by default:
pnpm install / pnpm dlx) — does not execute postinstall/prepare hooks unless explicitly allowlisted via onlyBuiltDependencies. pnpm v11+ also defaults to a 24-hour minimumReleaseAge cool-down.bunx) — same default, no lifecycle scripts unless allowlisted.min-release-age=7 and ignore-scripts=true in your global ~/.npmrc. Requires npm v11.10+ for min-release-age.None of our published packages need postinstall to function, so disabling lifecycle scripts in your installer of choice is safe.
