Summary
Connects to Microsoft Teams through the Graph API, letting Claude list your chats, read and send messages, browse teams and channels, and check presence status. Built by Mindstone as part of a 35-connector suite, this server shares host-orchestrated OAuth with their other Microsoft 365 connectors (Outlook mail, calendar, OneDrive files, SharePoint). Useful when you need an LLM to search chat history, send updates to team channels, or coordinate notifications based on availability. Ships with stdio transport and follows the same hardened supply-chain practices as the rest of the monorepo, including pinned dependencies, seven-day release cool-down, and provenance attestation on npm.

Quick Start
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.
Security & Hardening
This monorepo follows a defence-in-depth posture for tool-call hosts. Highlights include:
- Workflow safety. GitHub Actions workflows are env-fy'd against script injection (CWE-94), every action is pinned to a commit SHA (kept current by Dependabot), and each job is granted a least-privilege
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 onlynpm publish --ignore-scripts --provenanceunder OIDC trusted publishing, gated by thenpm-publishenvironment). The publish job invokes NO third-party JS —tsc,vitest, lifecycle scripts, etc. all run upstream, away fromid-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. - Release-age cool-down. The repo-level
.npmrcsetsmin-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. - Provenance-attested releases. Releases are published by CI (
.github/workflows/release.yml) under the@mindstone/npm scope via Trusted Publishing OIDC — no long-lived npm token exists anywhere — with--provenanceSigstore attestations consumers can verify vianpm audit signatures. Every publishable release commit must carry aRelease-Gatetrailer 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 runnpm pack; see MIGRATION.md.) - OpenSSF Scorecard. The repo runs the OpenSSF Scorecard weekly via
.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.
Recommendations for consumers
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 (
pnpm install/pnpm dlx) — does not executepostinstall/preparehooks unless explicitly allowlisted viaonlyBuiltDependencies. pnpm v11+ also defaults to a 24-hourminimumReleaseAgecool-down. - bun (
bunx) — same default, no lifecycle scripts unless allowlisted. - npm — if you must use npm, set
min-release-age=7andignore-scripts=truein your global~/.npmrc. Requires npm v11.10+ formin-release-age.
None of our published packages need postinstall to function, so disabling lifecycle scripts in your installer of choice is safe.
- Untrusted-content envelopes. External content from email, helpdesk, and ticketing systems (email-imap, freshdesk, zendesk) is wrapped in
<untrusted-content source="...">envelopes with close-tag breakout escaping, so an LLM host can recognise and refuse instruction-injection attempts. - Workspace sandboxing. File-uploading connectors (nano-banana, pandadoc, elevenlabs) constrain reads to
MCP_WORKSPACE_PATH(oros.tmpdir()) with canonical-prefix containment that handles symlinked roots like/tmp→/private/tmp. - Secure-by-default writes. Production-impacting writes (QuickBooks invoices/bills/customers/vendors) require an explicit
QB_ALLOW_PROD_WRITES=1opt-in env var; outreach prospect-enrolment and mixmax sequence-recipient tools carrydestructiveHint: trueso hosts surface confirmation prompts. - SSRF & path traversal. Download connectors (napkin, runway) enforce host allow-lists, manual-redirect handling, and symlink-safe write paths under a configurable root.
- Loopback OAuth bind. Connectors with local OAuth callback servers (salesforce, outreach) hard-code 127.0.0.1, ignoring any
MCP_OAUTH_BIND_HOSToverride. - E.164 validation. Outbound phone-call tools (retell-ai) reject non-E.164 numbers before any upstream API call.

The Mindstone open-source family
This repo is one of several open-source projects from Mindstone:
- Rebel — the AI workspace desktop app that ships these connectors out of the box (source release in progress).
- Super-MCP — a proxy MCP router that loads only the tools you actually need, saving your context window.
- rebel-system — the public Rebel system: skills, prompts, operators, help docs, and templates.
- meeting-note-recorder — meeting detection, recording, and live transcripts (the Rebel note-taker).
