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 Security89
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- 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
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability58
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 13769 tokens (~259/item across 53 items; 53 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage91
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 72% of tool parameters carry a description.Partial
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "list_wipe_jobs" implies "wipe" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Fail
- An AI judge read all 54 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

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 →
share_advisor_finding Share Advisor Finding ~172
Build a SHAREABLE package for ONE advisor finding — the max-context markdown + flat LLM prose + the permalink, so it can be dropped into a doc/chat/issue with full context (Finding · Analysis · Evidence · Deep links · Repro · Meta). Returns { format, permalink (https://dash.busymate.dev/advisor?sev&kind&f), advisor_url, markdown, llm_text } — `format` is an emphasis hint (markdown|llm|links) ECHOED BACK in the result (defaulted to markdown when omitted or unrecognized); every other field is returned regardless of it. Read-only. Gated audit:view.
| Name | Type | Req | Description |
|---|---|---|---|
| fingerprint | string | yes | The finding fingerprint. |
| format | string | – | Emphasis hint (default markdown); all fields returned. |

summarize_device_traffic Summarize Device Traffic ~315
BOUNDED traffic aggregation for ONE device — the FIRST tool to call to report what a device is doing, find the busy/flooding host, or pick a host to clean up. REQUIRES a device (`device_uuid` or `deviceName`) — a host alone is NOT enough: if you don't know which device, ask the user (or check list_devices) BEFORE calling. NEVER scans or returns raw rows (use it instead of search_entries/inspect_requests on a high-volume device — those time out at scale). Omit `host` → top hosts by request count (which host dominates). Pass `host` → top path-bases on that host with per-path count + last-seen (which endpoint floods). Optional absolute time range. Fast on 17k+ rows (one index-only GROUP BY). Returns ONLY {host|path_base, count, last_seen} — no headers/bodies.
| Name | Type | Req | Description |
|---|---|---|---|
| after | string | – | Only entries with ts >= this ISO date/datetime. |
| before | string | – | Only entries with ts < this ISO date/datetime. |
| deviceName | string | – | The device's name — an alternative to device_uuid; one of the two is REQUIRED. |
| device_uuid | string | – | REQUIRED unless deviceName is given — the device to summarize. |
| host | string | – | Omit for top hosts; pass a full hostname to get its top path-bases. |
| limit | number | – | Max groups (default 25, capped 100). |
No output schema declared.
No examples provided.
test_pac_connection Test PAC Connection ~472
PROVE whether PAC capture actually works for ONE device — the "is it really working?" answer, not "does it look configured". Runs 8 independent checks and returns a per-check verdict with a specific human fix: (1) connection mode — is the device even on `pac` (a `vpn`/`off` device is SAID SO plainly, never reported as broken PAC); (2) PAC port + URL — a pool port is allocated and http://<port>.busymate.net/ + /proxy.pac + /wpad.dat each serve HTTP 200 with the PAC content type; (3) THE HEADLINE — the PAC the proxy really serves this device carries a PROXY directive and is NOT the silent DIRECT fallback (a DIRECT PAC means the device bypasses capture ENTIRELY while looking perfectly configured — ~11k serves/day hit this); (4) egress IP is in the asserted allowlist (the dominant cause of that DIRECT fallback); (5) the proxy is really routing this device's requests right now; (6) the effective SSL-proxying list is NON-EMPTY and covers hosts the device actually contacts (an empty list = configured to decrypt NOTHING, which FAILS); (7) live decryption evidence — genuinely DECRYPTED requests for hosts in this device's OWN resolved list (a CONNECT envelope or a raw-TCP row is never counted as proof); (8) the device-reported CA-trust readiness + its exact remediation. Every check is pass | fail | unverified — a check that could not reach the thing it judges returns UNVERIFIED and is NEVER reported as healthy. Overall verdict ok | degraded | broken | unverified plus ONE plain-language next action. YOUR OWN (or demo) devices by default; testing someone else's device requires devices:view (re-verified server-side, fail-closed). Read-only, no confirm, changes nothing.
| Name | Type | Req | Description |
|---|---|---|---|
| deviceName | string | – | The device's name — an alternative to device_uuid; one of the two is REQUIRED. |
| device_uuid | string | – | REQUIRED unless deviceName is given — the device to test. |
| window_minutes | number | – | Lookback for the traffic + decryption checks (default 60, min 5, max 1440). |

Is the Busymate DevTools MCP server safe to use?
Busymate DevTools scores 86 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 Busymate DevTools MCP server expose?
Busymate DevTools exposes 53 tools: get_product_pricing, search_docs, read_docs_page, list_docs_sections, get_setup_steps, and 48 more. Their descriptions and schemas cost roughly 13,458 tokens of context every time the server is loaded.
Does the Busymate DevTools MCP server require authentication?
Yes. Busymate DevTools asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
Is the Busymate DevTools MCP server still maintained?
Busymate DevTools is still listed as active in the MCP registry. We last reached this channel on 7 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 Busymate DevTools MCP server?
VerifyMCP ran 13 checks on Busymate DevTools, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. 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.
