MCP Nexus (hirurg-lybitel/MCP-Nexus) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
Enables universal access to MCP tools and capabilities from external clients, client-side, and server-side within a Next.js application.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
minimatch ReDoS: nested *() extglobs generate catastrophically backtracking regular expressions
minimatch has a ReDoS via repeated wildcards with non-matching literal in pattern
minimatch has ReDoS: matchOne() combinatorial backtracking via multiple non-adjacent GLOBSTAR segments

FIREBIRD_ENV_FILE$env:="D:\git\gdmn-nxt\.env" # PowerShellHOSTHOSTNAMENEXT_PUBLIC_MCP_PORTNEXT_PUBLIC_OPENAI_SECURITY_KEYPORTTool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
7/7 tools missing one or more hints — get_humidity (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_current_temperature (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_rain_probability (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
6/7 tool handlers declare input schemas (86%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
4/7 tool handlers wrap calls in try/catch (57%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
5/7 tools referenced in tests (71%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Dev dependencies
3 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
