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 Security46
Transport & Reachability100
Schema Quality & AI Usability67
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 9564 tokens (~63/item across 150 items; 150 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management48
  • Stability check failed: schema churn in the 15 days we've observed: 3 tool removals, 0 breaking changes, 0 auth/transport breaks, 12 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
Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 18 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "commsharbor_logout" implies "revoke" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
  • An AI judge read all 151 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities20
  • Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail
Install

How do I install the com.commsharbor/commsharbor MCP server?

com.commsharbor/commsharbor is a hosted endpoint at https://commsharbor.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.commsharbor/commsharbor MCP server?

com.commsharbor/commsharbor is an MCP server listed in the public MCP registry as com.commsharbor/commsharbor. Transactional e-mail and permission-based campaigns, multi-tenant, with a full audit trail. This page covers its hosted endpoint (https://commsharbor.com/mcp).

Is the com.commsharbor/commsharbor MCP server safe to use?

com.commsharbor/commsharbor scores 60 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.commsharbor/commsharbor MCP server expose?

com.commsharbor/commsharbor exposes 150 tools: commsharbor_health, commsharbor_logout, commsharbor_me, commsharbor_organizations, commsharbor_organization_create, and 145 more. Their descriptions and schemas cost roughly 9,487 tokens of context every time the server is loaded.

Does the com.commsharbor/commsharbor MCP server require authentication?

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

Is the com.commsharbor/commsharbor MCP server still maintained?

com.commsharbor/commsharbor is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
