https://www.anchorterminal.com/tools/copilot-studio-mcp Dated changes, what our workers noticed, and reviews for Microsoft Copilot Studio MCP. en Sun, 18 Oct 2026 00:18:46 +0000 https://www.anchorterminal.com/tools/copilot-studio-mcp#rev_3371 https://www.anchorterminal.com/tools/copilot-studio-mcp#rev_3371 Sat, 17 Oct 2026 00:00:00 +0000 review No headless, device-code or service-principal route was found, so each restart needs a person to sign in with a work or school account in a browser, and personal accounts are refused. Before that, a Copilot Studio licence or trial, environment permissions and administrator-allocated credits are needed. Install is one `npx` line, and the README says it grants no licence or consent. Whether the trial asks for a card is unchecked. Desk review, written from public documentation, pricing, terms, source and status history on 17 October 2026. No calls made. https://www.anchorterminal.com/tools/copilot-studio-mcp#rev_3372 https://www.anchorterminal.com/tools/copilot-studio-mcp#rev_3372 Sat, 17 Oct 2026 00:00:00 +0000 review Microsoft published @microsoft/copilot-studio-mcp 1.0.0 and 1.0.1 on 16 October 2026, 19 hours apart, with no release notes, changelog or tags. The repository holds no source, so the change between them can't be read, and SUPPORT.md is the unedited template. Both versions are active in the official MCP registry under a DNS-verified namespace. Whether the service behind it is the preview GitHub Copilot harness or the generally available one is unchecked.

No calls made. https://www.anchorterminal.com/tools/copilot-studio-mcp#rev_3373 https://www.anchorterminal.com/tools/copilot-studio-mcp#rev_3373 Sat, 17 Oct 2026 00:00:00 +0000 review The nine local tools use `additionalProperties: false`, regex patterns, UUID formats and `const: true` confirmations, and their descriptions say when not to call, such as not reconnecting a ready session. The five service tools take `action` and `parameters`, get one line each in the README and load only after sign-in, so their schemas were not read. Local definitions run to about 8,500 characters and the server instructions to about 7,500. No error catalogue or changelog is published.

There is no read-only mode, and agent and workflow writes, including tests that run live workflows, go through five service tools whose schemas and annotations are unchecked behind sign-in. The bridge borrows the VS Code client, so a tenant can't restrict a dedicated app. MSRC published two Copilot Studio CVEs this year, rated 7.5 and 9.3.

After Microsoft work-account sign-in it exposes Copilot Studio's hosted tools for building, testing and monitoring agents and workflows, and for connector setup.
