What to fix (3)

5 parameter(s) across 2 tool(s) have no description.

Add a "description" to each parameter with its format and an example ("ISO 8601 date, e.g. 2026-10-17"). This is the commonest cause of wrong arguments on the first call. How to fix →

Tools: helixar_hdp_validate, helixar_inspect_mcp

2 of 2 tool(s) carry no readOnlyHint/destructiveHint annotations.

Annotate read-only tools with {"readOnlyHint": true}. Agents and gateways can then run them without a confirmation prompt, and route around destructive ones. How to fix →

Tools: helixar_hdp_validate, helixar_inspect_mcp

No tool declares an outputSchema.

Declare outputSchema and return structuredContent (MCP 2025-06-18+). Agents can then parse results without guessing, and chain tools reliably. How to fix →

Auto-fix: 1 corrected tool definition

Paste-ready definitions with the problems above fixed. Changes marked verify need a human look. 2 tool(s) still need parameter descriptions written by someone who knows the API. All of them as JSON: /v1/readiness/mcp-registry%2Fai.helixar%2Fmcp/fixes

How do I install Helixar MCP server?

Point your MCP client at this streamable-http endpoint: https://mcp.helixar.ai/mcp

Is the Helixar MCP server safe to connect to an AI agent?

Glimind scanned all 2 tool definitions for tool-poisoning patterns — hidden or invisible characters, instructions that override the model, concealment from the user, requests to read credential or MCP config files, conversation exfiltration and cross-tool shadowing — and found none. This checks what the server tells the model, not what its code does; review the source before granting access to sensitive data.
