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
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not yet verified: we couldn't confirm whether this endpoint requires it. View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 404, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport check failed: declared streamable-http, but the endpoint returned HTTP 404. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability0
- Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.Unverified

Unverified: 5 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

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 Company filing and CVE evidence snapshots MCP server?
Company filing and CVE evidence snapshots is a hosted endpoint at https://agent-research-fishnet.walsh-datascience.workers.dev/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.

What is the Company filing and CVE evidence snapshots MCP server?
Company filing and CVE evidence snapshots is an MCP server listed in the public MCP registry as io.github.Stavros65/fishnet-company-cve. Company filing/CVE snapshots, status and optional feedback. Remote MCP or local stdio. Free Phase A. This page covers its hosted endpoint (https://agent-research-fishnet.walsh-datascience.workers.dev/mcp).
Is the Company filing and CVE evidence snapshots MCP server safe to use?
Company filing and CVE evidence snapshots scores 18 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 Company filing and CVE evidence snapshots MCP server expose?
Company filing and CVE evidence snapshots exposes 3 tools: company_snapshot, cve_snapshot, submit_fishnet_feedback. Their descriptions and schemas cost roughly 775 tokens of context every time the server is loaded.
Does the Company filing and CVE evidence snapshots MCP server require authentication?
Its publisher declares no required credentials for Company filing and CVE evidence snapshots. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.
Is the Company filing and CVE evidence snapshots MCP server still maintained?
Company filing and CVE evidence snapshots 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 Company filing and CVE evidence snapshots MCP server?
VerifyMCP ran 4 checks on Company filing and CVE evidence snapshots, covering TLS certificate, HSTS header, DNSSEC and Transport. 7 items could not be completed, a gap on our side rather than a finding about Company filing and CVE evidence snapshots: Authorization, HTTPS, Schema quality, Stability and 3 more. 5 categories score 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
