Description
The Gunsnation MCP Server is a lightweight integration layer that exposes the Gunsnation firearms catalog to AI assistants through the Model Context Protocol (MCP). It allows compatible AI clients to search, filter, and retrieve detailed firearm information using structured tool calls instead of manual API integration.
What our measurements say
gunsnation-mcp is a remote MCP server published at api.gunsnation.com. It has been probed 7 times since 9/10/2026. It answered in 7 of them (100.0%), a near-uninterrupted record. Median response time is 475 ms, placing it among the faster endpoints. It offers a narrow, focused set of 12 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names clearly indicate their primary function (e.g., 'search_firearms', 'get_firearm')
- Some tools include detailed usage constraints (e.g., 'apply_firearm_faqs' specifies prohibited content types)
Weaknesses
- Parameter definitions are not explicitly documented in descriptions
- Potential overlap between 'list_brands' and 'list_vendors' could confuse agents
- Error handling and constraints are only mentioned for a subset of tools
mark_firearms_for_enrichment— Ambiguous parameter 'request scraper re-scrape' lacks explicit input schemaapply_firearm_enrichment— 'leave the rest out' is vague without defined required/optional fieldslist_brands— Functionally similar to 'list_vendors' with unclear differentiationapply_firearm_faqs— Prohibited content categories could be better structured as explicit constraints
Verdict
Event narrative
Risk: medium
- 2026-09-10T21:16:35.016Z — era changed from auth-gated to legacy · system transitioned to legacy state
- 2026-09-11T03:50:39.090Z — complianceScore set to 100, smokeOk set to true · system achieved full compliance and passed smoke tests
Advice
Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test passed · last run:
- Cold-start: cold 143ms → warm 150ms (penalty 0ms)
