Available components
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 Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- 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
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability78
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 705 tokens (~141/item across 5 items; 5 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 Coverage100
- 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
- Structured output schemas are declared (80% of tools); any adoption earns full credit.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "nexus_npm_package_ws_has_241560546_weekly_down_send_typed_ws_frame" implies "send" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the io.github.nexus-mcp-infra/npm-package-ws-has-241560546-week… server?
io.github.nexus-mcp-infra/npm-package-ws-has-241560546-week… is a hosted endpoint at https://npm-package-ws-has-241560546-w-production.up.railway.app/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.

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 →
nexus_npm_package_ws_has_241560546_weekly_down_close_websocket_session ~161
Sends a WebSocket close frame with the specified status code, waits for the server close handshake, and removes the session from the registry. Returns a final telemetry snapshot. Use when a session is no longer needed. Do NOT use to temporarily pause a session -- the session_id is permanently deallocated after this call and cannot be reused.
| Name | Type | Req | Description |
|---|---|---|---|
| reason | string | – | Optional UTF-8 close reason string, max 123 bytes per RFC 6455. |
| session_id | string | yes | 32-character session id of the session to close. |
| status_code | number | – | WebSocket close status code per RFC 6455 (1000-4999). Defaults to 1000. |
Structured output declared, but exposes no named fields.
No examples provided.
nexus_npm_package_ws_has_241560546_weekly_down_drain_ws_frame_buffer ~123
Returns up to max_frames buffered inbound frames received since the last drain (or session open), each annotated with its Shannon entropy delta and schema validation result. Use to poll for incoming messages without holding a blocking connection. Do NOT use as a real-time streaming mechanism -- it returns only frames already buffered.
| Name | Type | Req | Description |
|---|---|---|---|
| max_frames | number | – | Maximum number of buffered frames to return in a single call. |
| session_id | string | yes | 32-character session id of the open session to drain frames from. |
Structured output declared, but exposes no named fields.
No examples provided.
nexus_npm_package_ws_has_241560546_weekly_down_inspect_ws_session_telemetry ~110
Returns real-time telemetry for a session: connection state, frame counts, cumulative and rolling Shannon entropy statistics, schema violation rate, and uptime. Use to diagnose whether a stream is diverging from its expected schema or to verify a session is still alive before sending. Do NOT use as the primary liveness check in a tight loop.
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | 32-character session id of the session to inspect. |
Structured output declared, but exposes no named fields.
No examples provided.
nexus_npm_package_ws_has_241560546_weekly_down_open_websocket_session ~142
Establishes a persistent WebSocket connection to a target URL and registers it in the stateful session registry. Returns a session_id for all subsequent operations. Use when an agent needs to initiate a long-lived connection before sending or receiving frames. Do NOT use to reconnect an already-open session -- call close_websocket_session first, or use the session_id of an existing session.
| Name | Type | Req | Description |
|---|---|---|---|
| connect_timeout_seconds | number | – | Maximum seconds to wait for the WebSocket handshake to complete. |
| target_url | string | yes | Full WebSocket URL to connect to (must start with ws:// or wss://). |
No output schema declared.
No examples provided.
nexus_npm_package_ws_has_241560546_weekly_down_send_typed_ws_frame ~169
Sends a single text or binary frame over an open session and returns the frame's Shannon entropy delta relative to the session baseline. Use for request-response patterns or publishing commands to a WebSocket server. Do NOT use to send a sequence of frames in bulk -- call this tool once per frame. Fails if session_id does not exist or connection is not in OPEN state.
| Name | Type | Req | Description |
|---|---|---|---|
| frame_type | string | – | Either 'text' or 'binary'. Determines wire encoding. |
| payload | string | yes | Frame payload. For binary frames, encode as hex and set frame_type to 'binary'. |
| session_id | string | yes | 32-character session id (uuid4 hex, no dashes) returned by open_websocket_session. |
Structured output declared, but exposes no named fields.
No examples provided.
