Category Communication

Trust breakdown (7 categories)

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 image's dependency list comes from an SBOM its publisher attached, which nothing verifies, so we will not report it as a clean result.Unverified
  • Install-script risk not yet assessed.Unverified
  • Dependency health could not be checked: this image's dependency list comes from an SBOM its publisher attached. It names packages and versions but not whether each is deprecated, still maintained or linked to its source, so there is nothing we can fairly grade.Unverified
Provenance & Transparency31
Schema Quality & AI Usability0
  • Schema quality not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no schema to assess.Unverified
Stability & Change Management0
  • Stability not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no schema to compare.Unverified
Tool Coverage0
  • Tool coverage not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no tool definitions to assess.Unverified
Tool Safety0
  • Tool safety not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no tool text to scan.Unverified
Capabilities0
  • Protocol version not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we never saw its MCP handshake.Unverified

Unverified: 6 categories

Categories scored 0 because we could not verify them: 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.

Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

MCP tools

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 →

Tools for package channels are captured by running the package in an isolated sandbox. The most recent sandbox run could not capture a tool list from this package.

Install

How do I install the JMAP Email MCP server?

JMAP Email runs locally as a container image, launched with docker run --rm -i -e JMAP_SESSION_URL -e JMAP_AUTH_TOKEN ghcr.io/mikluko/jmap-mcp:0.10.0. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

oci · ghcr.io/mikluko/jmap-mcp:0.10.0

# add to Claude Code
claude mcp add mikluko-jmap-mcp -- docker run --rm -i -e JMAP_SESSION_URL -e JMAP_AUTH_TOKEN ghcr.io/mikluko/jmap-mcp:0.10.0

This image reads JMAP_SESSION_URL and JMAP_AUTH_TOKEN. Set them in your client's env block for this server; docker run -e passes each one through to the container.

Common questions

What is the JMAP Email MCP server?

JMAP Email is an MCP server listed in the public MCP registry as io.github.mikluko/jmap-mcp. Email management via JMAP, mailboxes, messages, identities, and Sieve scripts. This page covers its container image (ghcr.io/mikluko/jmap-mcp:0.10.0).

Is the JMAP Email MCP server safe to use?

JMAP Email scores 6 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.

Is the JMAP Email MCP server still maintained?

JMAP Email is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What did VerifyMCP test on the JMAP Email MCP server?

VerifyMCP ran 5 checks on JMAP Email, covering Source repository, Provenance, License, Maintenance and 1 more. 9 items could not be completed, a gap on our side rather than a finding about JMAP Email: Malware scan, Known CVEs, Install scripts, Dependency health and 5 more. 6 categories score 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to a container image, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
