How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →

Endpoint Security89
Transport & Reachability100
Schema Quality & AI Usability62
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 25001 tokens (~119/item across 209 items; 209 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 Management95
  • Stability check failed: schema churn in the 30 days we've observed: 7 tool removals, 1 breaking changes, 0 auth/transport breaks, 60 additions. See how to fix → Fail
Tool Coverage67
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 0% of tool parameters carry a description.Fail
Tool Safety98
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 12 of 13 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "run_gaql_query" implies "execute" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Partial
  • An AI judge read all 210 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 io.github.jshorwitz/synter-ads MCP server?

io.github.jshorwitz/synter-ads is a hosted endpoint at https://mcp.syntermedia.ai/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.

MCP tools · 209 exposed · ~20,927 tokens

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 io.github.jshorwitz/synter-ads MCP server?

io.github.jshorwitz/synter-ads is an MCP server listed in the public MCP registry as io.github.jshorwitz/synter-ads. Manage ad campaigns across Google, Meta, LinkedIn, Reddit, TikTok, and more via AI. This page covers its hosted endpoint (https://mcp.syntermedia.ai/mcp/).

Is the io.github.jshorwitz/synter-ads MCP server safe to use?

io.github.jshorwitz/synter-ads scores 85 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 io.github.jshorwitz/synter-ads MCP server expose?

io.github.jshorwitz/synter-ads exposes 209 tools: get_organic_publishing_readiness, draft_organic_post, validate_organic_post, approve_organic_post, schedule_organic_post, and 204 more. Their descriptions and schemas cost roughly 20,927 tokens of context every time the server is loaded.

Does the io.github.jshorwitz/synter-ads MCP server require authentication?

Yes. io.github.jshorwitz/synter-ads asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
