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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability79
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 2414 tokens (~100/item across 24 items; 14 tools + 10 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management50
- Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage86
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 57% 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 14 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 16 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
ask_aifree Ask aifree ~60
A short answer about free AI offers grounded in the verified catalog, citing only offer slugs it was shown. Declines questions outside the catalog. Cached per question for 24 h; subject to a daily budget.
| Name | Type | Req | Description |
|---|---|---|---|
| question | string | yes | – |
No output schema declared.
No examples provided.
build_stack Build a free AI stack ~186
The aifree.dev/stack builder: for a template (chat, rag, image, voice, agent, finetune) one free pick per slot (llm, emb, vec, host, gpu, tts, stt, image) with alternatives, the tightest published LLM requests per day, cards and programs to watch, and a shareable URL. Optionally pin a slot to an offer slug, require no card, or limit to a country.
| Name | Type | Req | Description |
|---|---|---|---|
| noCard | boolean | – | true = only offers that never ask for a card |
| picks | object | – | Pin slots to offer slugs, e.g. { "llm": "groq-free-tier" } |
| region | string | – | ISO 3166-1 alpha-2 code, e.g. "VN"; unknown codes are ignored |

No examples provided.
check_eligibility Check which free AI offers a profile can claim ~388
Use when someone asks what free AI they qualify for given who they are, e.g. "I am a student in Vietnam with no credit card, what free AI can I get?". Same rules as the aifree.dev/unlock quiz: student and startup programs only when the profile says so, no-card drops offers that ask for a card, country drops offers recorded as other-countries-only (offers with no recorded region stay in and are counted in unrecordedRegionCount), building narrows by category. All parameters are optional; omitted ones mean not a student, no startup, anywhere, card OK, any category. Unknown values are ignored the same way. Returns verified rows first, then by USD value. totalUsd sums USD headline values of verified rows only (tokens, requests, images or minutes count as $0, no exchange rates); listed rows are public but not yet checked by a person. limit (default 20, max 50) only trims the returned list: total, verifiedCount and totalUsd cover every match. Each provider decides who qualifies; cite the offer url and the unlockUrl (the same result as a page).
| Name | Type | Req | Description |
|---|---|---|---|
| building | string | – | any (default), coding, api-credits (apps on LLM APIs), image, audio, video, assistant |
| country | string | – | ISO 3166-1 alpha-2 code, e.g. "VN", "IN", "US"; unknown codes are ignored |
| limit | integer | – | – |
| noCard | boolean | – | true = will not enter a payment card |
| startupStage | string | – | none (default), idea (no company yet), early (incorporated, pre-seed or bootstrapped), funded (raised a round); anything but none adds startup programs |
| student | boolean | – | true = enrolled student (adds student programs) |

How do I install the io.github.minhtc/aifree MCP server?
io.github.minhtc/aifree is a hosted endpoint at https://aifree.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 io.github.minhtc/aifree MCP server?
io.github.minhtc/aifree is an MCP server listed in the public MCP registry as io.github.minhtc/aifree. Verified free AI offers, API free tiers, credits and student/startup programs from aifree.dev. This page covers its hosted endpoint (https://aifree.dev/mcp).
Is the io.github.minhtc/aifree MCP server safe to use?
io.github.minhtc/aifree scores 80 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 io.github.minhtc/aifree MCP server expose?
io.github.minhtc/aifree exposes 14 tools: search_free_ai_offers, get_offer, offer_history, list_free_llm_apis, find_models, and 9 more. Their descriptions and schemas cost roughly 1,867 tokens of context every time the server is loaded.
Does the io.github.minhtc/aifree MCP server require authentication?
No. We connected to io.github.minhtc/aifree without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the io.github.minhtc/aifree MCP server still maintained?
io.github.minhtc/aifree is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
