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 4 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 Usability69
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 2975 tokens (~106/item across 28 items; 28 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 Management13
- Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage74
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 22% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 28 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 29 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

How do I install the FreeTier Agent API MCP server?
FreeTier Agent API is a hosted endpoint at https://freetier-agent-api.pages.dev/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.

What is the FreeTier Agent API MCP server?
FreeTier Agent API is an MCP server listed in the public MCP registry as dev.pages.freetier-agent-api/freetier-agent-api. x402 pay-per-call data for agents: LLM prices, MCP/x402 directories, holidays, FX, page checks. This page covers its hosted endpoint (https://freetier-agent-api.pages.dev/mcp).
Is the FreeTier Agent API MCP server safe to use?
FreeTier Agent API scores 61 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the FreeTier Agent API MCP server expose?
FreeTier Agent API exposes 28 tools: list_endpoints, mcp_servers_sample, llm_pricing_sample, api_directory_sample, apis_search, and 23 more. Their descriptions and schemas cost roughly 2,919 tokens of context every time the server is loaded.
Does the FreeTier Agent API MCP server require authentication?
No. We connected to FreeTier Agent API without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the FreeTier Agent API MCP server still maintained?
FreeTier Agent API is still listed as active in the MCP registry. We last reached this channel on 22 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
