Endpoint Security46
Transport & Reachability100
Schema Quality & AI Usability68
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 2299 tokens (~153/item across 15 items; 15 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management96
  • Stability check failed: schema churn in the 30 days we've observed: 0 tool removals, 1 breaking changes, 0 auth/transport breaks, 0 additions. See how to fix → Fail
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
  • An AI judge read all 15 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the com.googleapis.stitch/mcp server?

com.googleapis.stitch/mcp is a hosted endpoint at https://stitch.googleapis.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the com.googleapis.stitch/mcp server?

com.googleapis.stitch/mcp is listed in the public MCP registry as com.googleapis.stitch/mcp. Interact with the Stitch API using natural language commands. This page covers its hosted endpoint (https://stitch.googleapis.com/mcp).

Is the com.googleapis.stitch/mcp server safe to use?

com.googleapis.stitch/mcp scores 72 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the com.googleapis.stitch/mcp server expose?

com.googleapis.stitch/mcp exposes 15 tools: create_project, get_project, delete_project, list_projects, list_screens, and 10 more. Their descriptions and schemas cost roughly 2,299 tokens of context every time the server is loaded.

Does the com.googleapis.stitch/mcp server require authentication?

No. We connected to com.googleapis.stitch/mcp without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the com.googleapis.stitch/mcp server still maintained?

com.googleapis.stitch/mcp is still listed as active in the MCP registry. We last reached this channel on 27 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
