ReqRes · reqres.in · who's behind it

ReqRes' hosted MCP server lets a coding agent create a real hosted REST backend with no account, persistent JSON collections and API keys, then read and write its records. Unclaimed projects are deleted after 72 hours.

Best for Coding agents that need a throwaway or starter backend for a prototype, with no account to set up.

Assessment. ReqRes' MCP server is the quickest way for a coding agent to stand up a real hosted backend, with no account, seven annotated tools and paginated records. Every result carries a sponsored line by default, the free tier is small, and unclaimed projects vanish after 72 hours.

Strengths

  • A hosted backend from one call, with no account
  • Seven compact annotated tools with paginated records
  • A claim link moves the project to an account with data intact
  • llms.txt and a plain REST API behind the tools

Weaknesses

  • A sponsored line in every successful result unless ?sponsor=0
  • Unclaimed projects are deleted after 72 hours
  • Free plan of 250 requests a day
  • Status page unreachable and no changelog

Before you call it notes for agents

  1. Add ?sponsor=0 to the server URL to keep ads out of context
  2. Give the user the claim link so the project survives 72 hours
  3. Use the public key in frontend code and keep the manage key server-side

The document

A reading by a fixed set of rules, each answered with the vendor's own sentence. It isn't legal advice, a rule can miss a clause or misread one, and the document itself is what binds. How it's read and scored.

Not looked up: RDAP isn't requested under the 1 November 2026 rules.

The operating company wasn't named in the parts of the terms and privacy policy read.

Checked 2026-11-07 against the vendor's own pages and the domain registry. Provenance is half of Transparency & trust.

Notable

  • Projects created without an account are deleted after 72 hours unless claimed source
  • Successful tool results end with a labelled sponsored message; ?sponsor=0 hides it source

Reviews by the Anchor panel

Every review here is a desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026. No calls made. The outcome says whether the reviewer's questions could be answered from public material. How reviews work.

Score breakdown methodology v0.7 · October 2026 research run

Assessed on 7 November 2026 from public evidence, against the published checklist. Confidence medium. Performance and Task success are pending until our probes and task suites run, so the total is over the 7 assessed categories, each weight divided by 80.

Fix list 15 items, the biggest gain first

Everything this grade says the listing lacks, from the reasons above, the checklist, the provenance checks, the deductions, what we couldn't check and what the review panel asked for, with the steps, ready to paste into a coding agent working on ReqRes MCP server. A fix counts at the next check, once it's public.

What we couldn't check

  • Paid plan prices and the operating company not read
  • People, ownership and investors not researched

  2. Tell us where it is

    We read it once now and again every week. If the link is missing two weeks in a row the listing says so, and a later check puts it back.

Agents send the same to POST /api/v1/verify as {"slug": "reqres-mcp", "url": "…"}, or call the verify_listing tool at /mcp. Ten checks an hour from one address. What we check. To announce the listing, get sharing assets for social media.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
