Category Security
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security0
- No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
- Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified

- Tool/resource definitions use about 1190 tokens (~108/item across 11 items; 10 tools + 1 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management13
- Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

- 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 Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 10 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass

Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

Background: How many MCP packages publish verified provenance →
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 →

How do I install the Mimecast MCP server?
Mimecast runs locally as a container image, launched with docker run --rm -i -e MIMECAST_CLIENT_ID -e MIMECAST_CLIENT_SECRET -e MIMECAST_REGION -e MCP_TRANSPORT -e AUTH_MODE -e LOG_LEVEL ghcr.io/wyre-ai/mimecast-mcp:v1.3.9. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

claude mcp add wyre-ai-mimecast-mcp -- docker run --rm -i -e MIMECAST_CLIENT_ID -e MIMECAST_CLIENT_SECRET -e MIMECAST_REGION -e MCP_TRANSPORT -e AUTH_MODE -e LOG_LEVEL ghcr.io/wyre-ai/mimecast-mcp:v1.3.9
This image reads MIMECAST_CLIENT_ID, MIMECAST_CLIENT_SECRET, MIMECAST_REGION, MCP_TRANSPORT, AUTH_MODE and LOG_LEVEL. Set them in your client's env block for this server; docker run -e passes each one through to the container.
What is the Mimecast MCP server?
Mimecast is an MCP server listed in the public MCP registry as io.github.WYRE-AI/mimecast-mcp. MCP server for Mimecast email security: message queue, held messages, domains, and threats. This page covers its container image (ghcr.io/wyre-ai/mimecast-mcp).
Is the Mimecast MCP server safe to use?
Mimecast scores 44 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 Mimecast MCP server expose?
Mimecast exposes 10 tools: mimecast_navigate, mimecast_status, mimecast_find_message, mimecast_get_message_info, mimecast_hold_message, and 5 more. Their descriptions and schemas cost roughly 1,172 tokens of context every time the server is loaded.
Is the Mimecast MCP server still maintained?
Mimecast is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
