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 Usability71
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1100 tokens (~137/item across 8 items; 8 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 Management50
- Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 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 tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. 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 →
early_offers Early-access offers (private feed) ~81
Offers that are verified but not public yet (embargoed, each with public_after), plus new, changed and closed offer events from the last 30 days, filtered by the subscription topics. Needs the private feed token from subscribe (webhook) or from the email confirmation page.
| Name | Type | Req | Description |
|---|---|---|---|
| token | string | yes | Private feed token (starts with pf_). |
No output schema declared.
No examples provided.
find_credits Find free credits for a need ~277
Answer "what free credits / free tier / startup program can I get for X". Ranked, verified offers matching a need such as "free speech to text credits", "GPU for a bootstrapped startup" or "student LLM API credits". Each result has credit_value, eligibility, how_to_claim, claim_url, source_url, source_snippet (verbatim vendor quote), last_verified, value_usd (explicit one-time USD amount or null), audience, and live claims / claims_7d / votes counts (real visitors, never padded; null if unavailable). filters.sort orders by relevance (default), popular (most claimed this week), votes, newest, verified (most recently re-checked), value (largest stated USD credit) or az. need may be empty when you only filter/sort. Closed offers are excluded unless filters.status is "all"/"closed" or include_closed is true. claim_redirect_url sends the user to the vendor and counts the claim anonymously; claim_url is the direct vendor link.
| Name | Type | Req | Description |
|---|---|---|---|
| filters | object | – | Optional filters. |
| need | string | – | What the user wants credits for, in plain words. E.g. "speech to text", "GPU compute for a bootstrapped startup", "vector database". May be empty ("") to list by filters and sort only. |
No output schema declared.
No examples provided.
get_offer Get one offer ~59
Full record for one Perq offer by id (e.g. "deepgram-200-credit"), including source quote, last_verified, recorded changes and packs that contain it.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Offer id from find_credits or a pack. |
No output schema declared.
No examples provided.
get_pack Get a pack ~60
One curated pack by slug with every offer in it and how its up-to total was computed (which offers counted and why others did not).
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Pack slug from list_packs, e.g. "llm-api-free-tier-pack". |
No output schema declared.
No examples provided.
list_packs List curated packs ~48
Curated bundles of offers (e.g. AI startup launch pack, LLM API free tier pack, voice AI pack) with each pack's headline and up-to total where one is computed.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
recently_changed Recently changed offers ~65
Offers added, updated (value, eligibility, claim steps) or closed in the last N days (dates in America/New_York).
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | – | Look-back window in days (default 7). |
| limit | integer | – | Max events returned (default 100). |
No output schema declared.
No examples provided.
subscribe Subscribe to early access ~192
Get newly verified offers before they are public on https://perq.sh (about 24h early), plus closures and changes. Give either email (a person: we send a confirmation link, then a digest only on days with something new) or webhook_url (an agent: https only, public hosts only; each new offer is POSTed as JSON signed with HMAC-SHA256). A webhook signup returns the signing secret once, a private feed token for early_offers, and the result of a signed verification ping. Only subscribe an address or URL the user asked you to.
| Name | Type | Req | Description |
|---|---|---|---|
| string | – | Email address to subscribe (double opt-in). | |
| topics | array | – | Optional topics; omit for everything. One of: llm-api, gpu, voice, startup-programs, student, agents, dev-tools. |
| webhook_url | string | – | https:// URL that receives signed JSON POSTs. |
No output schema declared.
No examples provided.
trending Most claimed / top voted this week ~122
Offers people are actually claiming (clicks on the claim link, one per visitor per day) or voting "worked for me", over the last 7 days or all time. Counts are real and never seeded; when nothing has been claimed yet the list is empty and says so.
| Name | Type | Req | Description |
|---|---|---|---|
| by | string | – | claims (default) or votes. |
| category | string | – | Optional category slug, e.g. llm-api. |
| limit | integer | – | Max results (default 10). |
| window | string | – | 7d (default) or all. |

How do I install the Perq MCP server?
Perq is a hosted endpoint at https://perq.sh/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 Perq MCP server?
Perq is an MCP server listed in the public MCP registry as sh.perq/perq. Verified free AI credits, free tiers and startup programs, each with source link and verified date. This page covers its hosted endpoint (https://perq.sh/mcp).
Is the Perq MCP server safe to use?
Perq 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 Perq MCP server expose?
Perq exposes 8 tools: find_credits, trending, get_offer, list_packs, get_pack, and 3 more. Their descriptions and schemas cost roughly 904 tokens of context every time the server is loaded.
Does the Perq MCP server require authentication?
No. We connected to Perq without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Perq MCP server still maintained?
Perq is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
