Third-party server, listed as discovered. Review its source before installing.
15 of 15 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 →
21 parameter(s) across 9 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 →
1 tool(s) have parameters with no type (no type/enum/anyOf/$ref).
Give every parameter a "type" (or "enum"/"anyOf"). Untyped parameters make models guess — strings for numbers, objects for arrays. How to fix →
In the last 30 days: 38 tool(s) removed and 0 schema change(s).
Add new tools or optional parameters instead of renaming or removing; deprecate first (say so in the description) and remove later. Agents cache tool contracts. How to fix →
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 →
3 tools share an identical description with another tool on this server.
Make each description say how the tool differs from its siblings, or the model will pick between them at random. How to fix →
Paste-ready definitions with the problems above fixed. Changes marked verify need a human look. 9 tool(s) still need parameter descriptions written by someone who knows the API. All of them as JSON: /v1/readiness/mcp-registry%2Fnet.fatstack%2Fregistry/fixes

Glimind records every version of this server's tool definitions in a signed, append-only transparency log. Current manifest sha256:22bb2a01b8e8f2ed…, first seen 2026-10-20, included at leaf 29891 of 35,704. Version history · verify what your client received.
Compare: most reliable search servers · most reliable security servers · most reliable devops servers · most reliable data servers · most reliable other servers
Glimind tells agents whether a server is up right now and how to call it, then fails over to a live alternative when it isn't.

As of 2026-10-20 22:55 UTC, the Fatstack Registry MCP server is up with a Glimind reliability score of 97/100 (grade A). Over the last 30 days it answered 100% of Glimind's liveness checks.
Fatstack Registry MCP server advertises 15 tools, including askzephy-quick-scan__google_news_feed, askzephy-quick-scan__sol_audit, askzephy-quick-scan__sol_quick_scan, cron-explain__cron_explain, csv-to-json__csv_to_json.

Glimind scanned all 15 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.
