See setup guidance ↓Original source ↗ SOURCE REVIEW Reviewed 2026-09-22 Evidence 6 linked sources Publisher Firebase Licence MIT ↗ Revision bb6de61f629f Read what was—and wasn’t—checked ↓ “local Model Context Protocol (MCP) server that runs in your development environment” Firebase · upstream description ↗ Our analysis follows below. 01 / THE REASONING ## Why this made the selection. - Uses the official Firebase CLI’s project and authentication context instead of a separate third-party dashboard scraper. - Connects project configuration, rules and service tools to the application workspace, making environment selection visible before a change. ### A good fit for - Inspecting a Firebase application’s project context and security-rule configuration - Performing explicitly authorized Firebase development tasks with existing account permissions ### Weigh up before choosing - This is not a read-only connector. Available tools include user administration, data changes, messaging and deployment-related operations. - Tool availability depends on credentials, selected project, workspace and configured feature/tool filters. Core tools remain available when feature groups are narrowed. - Authentication grants and an enabled tool are not approval for a production change. Confirm the target project and possible service charges. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - Official MCP setup and capability guide - src/commands/mcp.ts - src/mcp/index.ts and tool registry - Relevant package metadata and licence ### Our findings - The MCP initialization, authentication context and tool filtering were inspected. - The registration path exposes mutating capabilities; this was not a full security audit of every Firebase tool. ### Not established by this review - No MCP server or upstream package was installed or run. - No authenticated account, API request, client handshake or write operation was tested. The review applies to the material and revision named here. A newer upstream release can change its behavior. 03 / PUT IT TO WORK ## Connect a server deliberately. Upstream setup instructions ↗ DOCUMENTED COMMAND npx -y firebase-tools@latest mcp Copy command ↗ Copying does not execute this command. It may retrieve a newer version than the reviewed source. - Use the publisher’s client-specific configuration for the local Firebase CLI MCP process. - Authenticate through the supported Firebase CLI/ADC path and explicitly select the intended project/workspace. - Inspect the available tools and narrow feature/tool selection as documented before granting the assistant operational access. ### Before you start - Node.js/npm supported by the current Firebase CLI - A Firebase/Google account with the required project permissions - Project configuration and credentials appropriate to the intended environment ### Compatibility Antigravity · Claude Code · Claude Desktop · Cline · Cursor · VS Code · Windsurf ### Implementation TypeScript ### Transports stdio ### Local MCP process with service access - Read the active Firebase project and application configuration - Authorized tools can change users, database content, messaging or deployed configuration - Local workspace access and Google/Firebase API requests use the host and account permissions ### Cost model MIT-licensed CLI; Firebase service usage, account entitlements and assistant/model usage are separate. 04 / FOLLOW THE EVIDENCE ## The source trail. Our notes are separate from the original resource. Check upstream before adopting a new version. - Publisher README at reviewed revision ↗ Checked 2026-09-22 https://github.com/firebase/firebase-tools/blob/bb6de61f629fc3536c2b673acd02ff6a4cf6a70e/README.md Supports: summary, upstreamDescription, whySelected, bestFor, install, compatibility, limitations, access - Source licence ↗ Checked 2026-09-22 https://github.com/firebase/firebase-tools/blob/bb6de61f629fc3536c2b673acd02ff6a4cf6a70e/LICENSE Supports: license, access.cost - Reviewed implementation: src/commands/mcp.ts ↗ Checked 2026-09-22 https://github.com/firebase/firebase-tools/blob/bb6de61f629fc3536c2b673acd02ff6a4cf6a70e/src/commands/mcp.ts Supports: review, limitations, access, transports - Reviewed implementation: src/mcp/index.ts ↗ Checked 2026-09-22 https://github.com/firebase/firebase-tools/blob/bb6de61f629fc3536c2b673acd02ff6a4cf6a70e/src/mcp/index.ts Supports: review, limitations, access, transports - Reviewed implementation: src/mcp/tools/index.ts ↗ Checked 2026-09-22 https://github.com/firebase/firebase-tools/blob/bb6de61f629fc3536c2b673acd02ff6a4cf6a70e/src/mcp/tools/index.ts Supports: review, limitations, access, transports - Official Firebase MCP guide ↗ Checked 2026-09-22 https://firebase.google.com/docs/ai-assistance/mcp-server Supports: upstreamDescription, summary, install, compatibility, access, limitations, transports KEEP COMPARING ## Other approaches to consider.
