Category Communication
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: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified

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 Spacemail by NWD MCP server?
Spacemail by NWD ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. Before opening it, check the file's SHA-256 matches the one the MCP registry declares for it, 9fddd5945c46550058b5fd81121c3db9773f157fc1664654a97527ad3a1431c7; the commands to do that are on this page. If it does not match, do not open it.

Run it in the folder you saved the bundle to, then open the file with an MCPB-capable host such as Claude Desktop.
What is the Spacemail by NWD MCP server?
Spacemail by NWD is an MCP server listed in the public MCP registry as design.norwichwebsite/spacemail. Check, search, read and draft replies to Spacemail (Spaceship) emails, across several mailboxes. This page covers its MCPB bundle (https://github.com/evilash182/spacemail-mcp/releases/download/v1.0.1/spacemail.mcpb).
Is the Spacemail by NWD MCP server safe to use?
Spacemail by NWD scores 40 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 Spacemail by NWD MCP server expose?
Spacemail by NWD exposes 10 tools: list_mailboxes, test_connection, check_inbox, search_emails, read_email, and 5 more. Their descriptions and schemas cost roughly 1,375 tokens of context every time the server is loaded.
What licence is the Spacemail by NWD MCP server under?
Spacemail by NWD declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
What did VerifyMCP test on the Spacemail by NWD MCP server?
VerifyMCP ran 11 checks on Spacemail by NWD, covering Source repository, Provenance, License, Maintenance and 7 more. 5 items could not be completed, a gap on our side rather than a finding about Spacemail by NWD: Malware scan, Known CVEs, Install scripts, Dependency health and 1 more. 2 categories score 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to an MCPB bundle, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
